xcodeproj adds framework but linker can't find it - ios

I'm adding a custom framework to my Xcode project using the xcodeproj Ruby Gem:
top_group = project.groups[0]
framework_ref = top_group.new_file(framework_path)
target = project.targets[0]
target.frameworks_build_phase.add_file_reference(framework_ref)
When I then open Xcode and look at the target, the framework is listed correctly under Linked Frameworks and Libraries, yet the linker complains that the framework cannot be found when building. Dragging the framework in the Linked Frameworks list in Xcode fixes it, and I can build successfully.
Why? Dragging seems to force Xcode to regenerate the project.pbxproj and add a missing reference. What would that be?

you need to set the path where your framework is!
append the path in build settings for "FRAMEWORK_SEARCH_PATHS"
settings = target.build_settings("Debug")
settings["FRAMEWORK_SEARCH_PATHS"] = [settings["FRAMEWORK_SEARCH_PATHS"], your_framework_directory ]
or
settings["FRAMEWORK_SEARCH_PATHS"] = settings["FRAMEWORK_SEARCH_PATHS"] + " " + your_framework_directory ]

Append the path in build setting as follows:
#Add framework search path
settings = target.build_settings("Release")
settings["FRAMEWORK_SEARCH_PATHS"] = Array(settings["FRAMEWORK_SEARCH_PATHS"])<< '$(PROJECT_DIR)/SDK'
settings["LIBRARY_SEARCH_PATHS"] = Array(settings["LIBRARY_SEARCH_PATHS"])<< '$(PROJECT_DIR)/SDK'

References to Removed Framework in project.pbxproj File

I recently removed a framework from my iOS project and am installing it instead through a dependency manager (CocoaPods). I noticed, however, when checking my changes in to source control that some references to the framework were removed, but one was added with an absolute path. From the diff (the first line was removed and the second line added to my project file):
- 767C7EC51DB295CE00A8850F /* TealiumIOSLifecycle.framework */ = {isa = PBXFileReference; lastKnownFileType = wrapper.framework; path = TealiumIOSLifecycle.framework; sourceTree = "<group>"; };
+ 767C7EC51DB295CE00A8850F /* TealiumIOSLifecycle.framework */ = {isa = PBXFileReference; lastKnownFileType = wrapper.framework; name = TealiumIOSLifecycle.framework; path = /Users/jal/workspace/com.myapp/MyApp/Shared/ThirdParty/TealiumIOSLifecycle.framework; sourceTree = "<absolute>"; };
There is no file at that path on my local machine, and I was able to make a fresh clone in a separate directory and on other machines with a different directory structure and was able to build the project without any warnings or errors. The physical file of the framework no longer exists in the project directory (when I removed the file from the project in Xcode, I chose "move to trash).
Is this normal? If not, how can I remove these references?
To be clear, there are no references to this framework anywhere in the project. This includes Linked Frameworks and Libraries, Link Binary with Libraries, Target Dependencies, Embed Frameworks, etc.
Tap on your project file in xcode and in the General tab scroll down and check that it is not included in the following sections
The missing frameworks would be probably highlighted in red (or faded in gray i don't remember exactly)
Also in the build phases check it's not being tried to be copied

Xcode 8 Beta - Convert to Current Swift Syntax Failed: Could not find test host

I am receiving an error message when I try to use Xcode 8's Convert Wizard.
After trying rebooting, downloading fresh code, and deleting my DerivedData files I cannot escape this error:
Convert to Current Swift Syntax Failed: Could not find test host
I have tried both options which are: Swift 2.3 and Swift 3. After I select a version I instantly get that error.
Here is a screenshot of the error:
This worked for me:
Select the Xcode project in the lefthand browser.
Click on your test target in the Project's General tab.
Disclose "Testing". In my project the "Host Application" pulldown button was blank. Select your appropriate host application.
Try building your test target now. If that succeeds then converting syntax should as well.
I had this problem after installing the Xcode 8 beta so I assume this is related.
Picture Credit to #karthikkck
It cost me a bit of time to find the "Host Application" pulldown mentioned in the otherwise very helpful answer by iluvcapra.
So this is what he meant:
This is where you find the pulldown menu. Select your main target.
I find easy fix for this, just edit your Scheme and disable tests.
And run conversion again.
+1 iluvcapra
Alternatively, use text editor to remove the following two items from your MyAppSwift.xcodeproj/project.pbxproj file, search for TEST_HOST
Now, re-open your project and run the convert wizard again.
4EFFFAE51B53D5D8003CD25A /* Debug */ = {
isa = XCBuildConfiguration;
buildSettings = {
BUNDLE_LOADER = "$(TEST_HOST)";
FRAMEWORK_SEARCH_PATHS = (
"$(SDKROOT)/Developer/Library/Frameworks",
"$(inherited)",
);
GCC_PREPROCESSOR_DEFINITIONS = (
"DEBUG=1",
"$(inherited)",
);
INFOPLIST_FILE = "AF SwiftTests/Info.plist";
LD_RUNPATH_SEARCH_PATHS = "$(inherited) #executable_path/Frameworks #loader_path/Frameworks";
PRODUCT_NAME = "FA SwiftTests";
TEST_HOST = "$(BUILT_PRODUCTS_DIR)/AF Swift.app/AF Swift";
};
name = Debug;
};
4EFFFAE61B53D5D8003CD25A /* Release */ = {
isa = XCBuildConfiguration;
buildSettings = {
BUNDLE_LOADER = "$(TEST_HOST)";
FRAMEWORK_SEARCH_PATHS = (
"$(SDKROOT)/Developer/Library/Frameworks",
"$(inherited)",
);
INFOPLIST_FILE = "AF SwiftTests/Info.plist";
LD_RUNPATH_SEARCH_PATHS = "$(inherited) #executable_path/Frameworks #loader_path/Frameworks";
PRODUCT_NAME = "FA SwiftTests";
TEST_HOST = "$(BUILT_PRODUCTS_DIR)/AF Swift.app/AF Swift";
};
name = Release;
};
Please try these Steps:
Select your project on the left side of Xcode.
Go to Targets and select your Project Tests.
Select the General Tab and select Host Application drop down and choose your Host Application.
Convert or Run your project.
Trying these steps worked for me.
In my case I deleted my tests target, then re-added it using the + below targets and selecting "iOs Unit Testing Bundle"
For some reason this got a compile error, so I changed the "Per-configuration Intermediate Build Files Path: for my test target to $(PROJECT_TEMP_DIR)/$(CONFIGURATION) for both debug and release. This allowed the compile to work.
Fix this in 3 steps:
First delete your test target
The select Edit -> Convert -> To current Swift syntax... and perform the conversion
Then add a new test target

Importing CommonCrypto in a Swift framework

How do you import CommonCrypto in a Swift framework for iOS?
I understand how to use CommonCrypto in a Swift app:
You add #import <CommonCrypto/CommonCrypto.h> to the bridging header.
However, Swift frameworks don't support bridging headers. The documentation says:
You can import external frameworks that have a pure Objective-C codebase, a pure Swift codebase, or a mixed-language codebase. The
process for importing an external framework is the same whether the
framework is written in a single language or contains files from both
languages. When you import an external framework, make sure the
Defines Module build setting for the framework you’re importing is set
to Yes.
You can import a framework into any Swift file within a different
target using the following syntax:
import FrameworkName
Unfortunately, import CommonCrypto doesn't work. Neither does adding #import <CommonCrypto/CommonCrypto.h> to the umbrella header.
Something a little simpler and more robust is to create an Aggregate target called "CommonCryptoModuleMap" with a Run Script phase to generate the module map automatically and with the correct Xcode/SDK path:
The Run Script phase should contain this bash:
# This if-statement means we'll only run the main script if the CommonCryptoModuleMap directory doesn't exist
# Because otherwise the rest of the script causes a full recompile for anything where CommonCrypto is a dependency
# Do a "Clean Build Folder" to remove this directory and trigger the rest of the script to run
if [ -d "${BUILT_PRODUCTS_DIR}/CommonCryptoModuleMap" ]; then
echo "${BUILT_PRODUCTS_DIR}/CommonCryptoModuleMap directory already exists, so skipping the rest of the script."
exit 0
fi
mkdir -p "${BUILT_PRODUCTS_DIR}/CommonCryptoModuleMap"
cat <<EOF > "${BUILT_PRODUCTS_DIR}/CommonCryptoModuleMap/module.modulemap"
module CommonCrypto [system] {
header "${SDKROOT}/usr/include/CommonCrypto/CommonCrypto.h"
export *
}
EOF
Using shell code and ${SDKROOT} means you don't have to hard code the Xcode.app path which can vary system-to-system, especially if you use xcode-select to switch to a beta version, or are building on a CI server where multiple versions are installed in non-standard locations. You also don't need to hard code the SDK so this should work for iOS, macOS, etc. You also don't need to have anything sitting in your project's source directory.
After creating this target, make your library/framework depend on it with a Target Dependencies item:
This will ensure the module map is generated before your framework is built.
macOS note: If you're supporting macOS as well, you'll need to add macosx to the Supported Platforms build setting on the new aggregate target you just created, otherwise it won't put the module map in the correct Debug derived data folder with the rest of the framework products.
Next, add the module map's parent directory, ${BUILT_PRODUCTS_DIR}/CommonCryptoModuleMap, to the "Import Paths" build setting under the Swift section (SWIFT_INCLUDE_PATHS):
Remember to add a $(inherited) line if you have search paths defined at the project or xcconfig level.
That's it, you should now be able to import CommonCrypto
Update for Xcode 10
Xcode 10 now ships with a CommonCrypto module map making this workaround unnecessary. If you would like to support both Xcode 9 and 10 you can do a check in the Run Script phase to see if the module map exists or not, e.g.
COMMON_CRYPTO_DIR="${SDKROOT}/usr/include/CommonCrypto"
if [ -f "${COMMON_CRYPTO_DIR}/module.modulemap" ]
then
echo "CommonCrypto already exists, skipping"
else
# generate the module map, using the original code above
fi
You can actually build a solution that "just works" (no need to copy a module.modulemap and SWIFT_INCLUDE_PATHS settings over to your project, as required by other solutions here), but it does require you to create a dummy framework/module that you'll import into your framework proper. We can also ensure it works regardless of platform (iphoneos, iphonesimulator, or macosx).
Add a new framework target to your project and name it after the system library, e.g., "CommonCrypto". (You can delete the umbrella header, CommonCrypto.h.)
Add a new Configuration Settings File and name it, e.g., "CommonCrypto.xcconfig". (Don't check any of your targets for inclusion.) Populate it with the following:
MODULEMAP_FILE[sdk=iphoneos*] = \
$(SRCROOT)/CommonCrypto/iphoneos.modulemap
MODULEMAP_FILE[sdk=iphonesimulator*] = \
$(SRCROOT)/CommonCrypto/iphonesimulator.modulemap
MODULEMAP_FILE[sdk=macosx*] = \
$(SRCROOT)/CommonCrypto/macosx.modulemap
Create the three referenced module map files, above, and populate them with the following:
iphoneos.modulemap
module CommonCrypto [system] {
header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h"
export *
}
iphonesimulator.modulemap
module CommonCrypto [system] {
header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/CommonCrypto/CommonCrypto.h"
export *
}
macosx.modulemap
module CommonCrypto [system] {
header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/CommonCrypto/CommonCrypto.h"
export *
}
(Replace "Xcode.app" with "Xcode-beta.app" if you're running a beta version. Replace 10.11 with your current OS SDK if not running El Capitan.)
On the Info tab of your project settings, under Configurations, set the Debug and Release configurations of CommonCrypto to CommonCrypto (referencing CommonCrypto.xcconfig).
On your framework target's Build Phases tab, add the CommonCrypto framework to Target Dependencies. Additionally add libcommonCrypto.dylib to the Link Binary With Libraries build phase.
Select CommonCrypto.framework in Products and make sure its Target Membership for your wrapper is set to Optional.
You should now be able to build, run and import CommonCrypto in your wrapper framework.
For an example, see how SQLite.swift uses a dummy sqlite3.framework.
I found a GitHub project that successfully uses CommonCrypto in a Swift framework: SHA256-Swift. Also, this article about the same problem with sqlite3 was useful.
Based on the above, the steps are:
1) Create a CommonCrypto directory inside the project directory. Within, create a module.map file. The module map will allow us to use the CommonCrypto library as a module within Swift. Its contents are:
module CommonCrypto [system] {
header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.0.sdk/usr/include/CommonCrypto/CommonCrypto.h"
link "CommonCrypto"
export *
}
2) In Build Settings, within Swift Compiler - Search Paths, add the CommonCrypto directory to Import Paths (SWIFT_INCLUDE_PATHS).
3) Finally, import CommonCrypto inside your Swift files as any other modules. For example:
import CommonCrypto
extension String {
func hnk_MD5String() -> String {
if let data = self.dataUsingEncoding(NSUTF8StringEncoding)
{
let result = NSMutableData(length: Int(CC_MD5_DIGEST_LENGTH))
let resultBytes = UnsafeMutablePointer<CUnsignedChar>(result.mutableBytes)
CC_MD5(data.bytes, CC_LONG(data.length), resultBytes)
let resultEnumerator = UnsafeBufferPointer<CUnsignedChar>(start: resultBytes, length: result.length)
let MD5 = NSMutableString()
for c in resultEnumerator {
MD5.appendFormat("%02x", c)
}
return MD5
}
return ""
}
}
Limitations
Using the custom framework in another project fails at compile time with the error missing required module 'CommonCrypto'. This is because the CommonCrypto module does not appear to be included with the custom framework. A workaround is to repeat step 2 (setting Import Paths) in the project that uses the framework.
The module map is not platform independent (it currently points to a specific platform, the iOS 8 Simulator). I don't know how to make the header path relative to the current platform.
Updates for iOS 8 <= We should remove the line link "CommonCrypto", to get the successful compilation.
UPDATE / EDIT
I kept getting the following build error:
ld: library not found for -lCommonCrypto for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Unless I removed the line link "CommonCrypto" from the module.map file I created. Once I removed this line it built ok.
This answer discusses how to make it work inside a framework, and with Cocoapods and Carthage
🐟 modulemap approach
I use modulemap in my wrapper around CommonCrypto https://github.com/onmyway133/arcane, https://github.com/onmyway133/Reindeer
For those getting header not found, please take a look https://github.com/onmyway133/Arcane/issues/4 or run xcode-select --install
Make a folder CCommonCrypto containing module.modulemap
module CCommonCrypto {
header "/usr/include/CommonCrypto/CommonCrypto.h"
export *
}
Go to Built Settings -> Import Paths
${SRCROOT}/Sources/CCommonCrypto
🌳 Cocoapods with modulemap approach
Here is the podspec https://github.com/onmyway133/Arcane/blob/master/Arcane.podspec
s.source_files = 'Sources/**/*.swift'
s.xcconfig = { 'SWIFT_INCLUDE_PATHS' =>
'$(PODS_ROOT)/CommonCryptoSwift/Sources/CCommonCrypto' }
s.preserve_paths = 'Sources/CCommonCrypto/module.modulemap'
Using module_map does not work, see https://github.com/CocoaPods/CocoaPods/issues/5271
Using Local Development Pod with path does not work, see https://github.com/CocoaPods/CocoaPods/issues/809
That's why you see that my Example Podfile https://github.com/onmyway133/CommonCrypto.swift/blob/master/Example/CommonCryptoSwiftDemo/Podfile points to the git repo
target 'CommonCryptoSwiftDemo' do
pod 'CommonCryptoSwift', :git => 'https://github.com/onmyway133/CommonCrypto.swift'
end
🐘 public header approach
Ji is a wrapper around libxml2, and it uses public header approach
It has a header file https://github.com/honghaoz/Ji/blob/master/Source/Ji.h with Target Membership set to Public
It has a list of header files for libxml2 https://github.com/honghaoz/Ji/tree/master/Source/Ji-libxml
It has Build Settings -> Header Search Paths
$(SDKROOT)/usr/include/libxml2
It has Build Settings -> Other Linker Flags
-lxml2
🐏 Cocoapods with public header approach
Take a look at the podspec https://github.com/honghaoz/Ji/blob/master/Ji.podspec
s.libraries = "xml2"
s.xcconfig = { 'HEADER_SEARCH_PATHS' => '$(SDKROOT)/usr/include/libxml2', 'OTHER_LDFLAGS' => '-lxml2' }

How to call C from Swift?
https://spin.atomicobject.com/2015/02/23/c-libraries-swift/
Good news! Swift 4.2 (Xcode 10) finally provides CommonCrypto!
Just add import CommonCrypto in your swift file.
WARNING: iTunesConnect may reject apps that are using this method.
New member on my team accidentally broke the solution given by one of the top answers, so I decided to consolidate it in a small wrapper project called CommonCryptoModule. You can install it manually or via Cocoapods:
pod 'CommonCryptoModule', '~> 1.0.2'
Then, all you have to do is to import the module where you need CommonCrypto, like so:
import CommonCryptoModule
Hope someone else finds this useful.
I think I have an improvement to Mike Weller's excellent work.
Add a Run Script phase before the Compile Sources phase containing this bash:
# This if-statement means we'll only run the main script if the
# CommonCrypto.framework directory doesn't exist because otherwise
# the rest of the script causes a full recompile for anything
# where CommonCrypto is a dependency
# Do a "Clean Build Folder" to remove this directory and trigger
# the rest of the script to run
FRAMEWORK_DIR="${BUILT_PRODUCTS_DIR}/CommonCrypto.framework"
if [ -d "${FRAMEWORK_DIR}" ]; then
echo "${FRAMEWORK_DIR} already exists, so skipping the rest of the script."
exit 0
fi
mkdir -p "${FRAMEWORK_DIR}/Modules"
cat <<EOF > "${FRAMEWORK_DIR}/Modules/module.modulemap"
module CommonCrypto [system] {
header "${SDKROOT}/usr/include/CommonCrypto/CommonCrypto.h"
export *
}
EOF
ln -sf "${SDKROOT}/usr/include/CommonCrypto" "${FRAMEWORK_DIR}/Headers"
This script constructs a bare bones framework with the module.map in the correct place and then relies on Xcode's automatic search of BUILT_PRODUCTS_DIR for frameworks.
I linked the original CommonCrypto include folder as the framework's Headers folder so the result should also function for Objective C projects.
For anyone using swift 4.2 with Xcode 10:
CommonCrypto module is now provided by the system, so you can directly import it like any other system framework.
import CommonCrypto
#mogstad has been kind enough to wrap #stephencelis solution in a Cocoapod:
pod 'libCommonCrypto'
The other pods available did not work for me.
The modulemap solutions can be good, and are robust against SDK changes, but I've found them awkward to use in practice, and not as reliable as I'd like when handing things out to others. To try to make it all more foolproof, I went a different way:
Just copy the headers.
I know, fragile. But Apple almost never makes significant changes to CommonCrypto and I'm living the dream that they will not change it in any significant way without also finally making CommonCrypto a modular header.
By "copy the headers" I mean "cut and paste all of the headers you need into one massive header in your project just like the preprocessor would do." As an example of this that you can copy or adapt, see RNCryptor.h.
Note that all of these files are licensed under APSL 2.0, and this approach intentionally maintains the copyright and license notices. My concatenation step is licensed under MIT, and that only applies up to the next license notice).
I am not saying this is a beautiful solution, but so far it seems to have been an incredibly simple solution to both implement and support.
I know this is an old question. But I figure out an alternative way to use the library in Swift project, which might be helpful for those who don't want to import framework introduced in these answers.
In Swift project, create a Objective-C bridging header, create NSData category (or custom class that to use the library) in Objective-C. The only drawback would be that you have to write all implementation code in Objective-C.
For example:
#import "NSData+NSDataEncryptionExtension.h"
#import <CommonCrypto/CommonCryptor.h>
#implementation NSData (NSDataEncryptionExtension)
- (NSData *)AES256EncryptWithKey:(NSString *)key {
//do something
}
- (NSData *)AES256DecryptWithKey:(NSString *)key {
//do something
}
And then in your objective-c bridging header, add this
#import "NSData+NSDataEncryptionExtension.h"
And then in Swift class do similar thing:
public extension String {
func encryp(withKey key:String) -> String? {
if let data = self.data(using: .utf8), let encrypedData = NSData(data: data).aes256Encrypt(withKey: key) {
return encrypedData.base64EncodedString()
}
return nil
}
func decryp(withKey key:String) -> String? {
if let data = NSData(base64Encoded: self, options: []), let decrypedData = data.aes256Decrypt(withKey: key) {
return decrypedData.UTF8String
}
return nil
}
}
It works as expected.
I've added some cocoapods magic to jjrscott's answer in case you need to use CommonCrypto in your cocoapods library.
1) Add this line to your podspec:
s.script_phase = { :name => 'CommonCrypto', :script => 'sh $PROJECT_DIR/../../install_common_crypto.sh', :execution_position => :before_compile }
2) Save this in your library folder or wherever you like (however don't forget to change the script_phase accordingly ...)
# This if-statement means we'll only run the main script if the
# CommonCrypto.framework directory doesn't exist because otherwise
# the rest of the script causes a full recompile for anything
# where CommonCrypto is a dependency
# Do a "Clean Build Folder" to remove this directory and trigger
# the rest of the script to run
FRAMEWORK_DIR="${BUILT_PRODUCTS_DIR}/CommonCrypto.framework"
if [ -d "${FRAMEWORK_DIR}" ]; then
echo "${FRAMEWORK_DIR} already exists, so skipping the rest of the script."
exit 0
fi
mkdir -p "${FRAMEWORK_DIR}/Modules"
echo "module CommonCrypto [system] {
header "${SDKROOT}/usr/include/CommonCrypto/CommonCrypto.h"
export *
}" >> "${FRAMEWORK_DIR}/Modules/module.modulemap"
ln -sf "${SDKROOT}/usr/include/CommonCrypto" "${FRAMEWORK_DIR}/Headers"
Works like a charm :)
I'm not sure if something's changed with Xcode 9.2 but it's now much simpler to achieve this. The only things I had to do are create a folder called "CommonCrypto" in my framework project directory and create two files inside it, one called "cc.h" as follows:
#include <CommonCrypto/CommonCrypto.h>
#include <CommonCrypto/CommonRandom.h>
And another called module.modulemap:
module CommonCrypto {
export *
header "cc.h"
}
(I don't know why you can't reference header files from the SDKROOT area directly in a modulemap file but I couldn't get it to work)
The third thing is to find the "Import Paths" setting and set to $(SRCROOT).
In fact you can set it to whatever folder you want the CommonCrypto folder to be under, if you don't want it at the root level.
After this you should be able to use
import CommonCrypto
In any swift file and all the types/functions/etc. are available.
A word of warning though - if your app uses libCommonCrypto (or libcoreCrypto) it's exceptionally easy for a not-too-sophisticated hacker to attach a debugger to your app and find out what keys are being passed to these functions.
In case you have the below issue :
ld: library not found for -lapple_crypto
clang: error: linker command failed with exit code 1 (use -v to see invocation)
In Xcode 10, Swift 4.0. CommonCrypto is a part of the framework.
Add
import CommonCrypto
Remove
CommonCrpto lib file from link binary with libraries from Build
phases
import CommonCrypto from Bridging header
This worked for me!
It happened the same to me after updating Xcode.
I tried everything I can do such as reinstalling cocoapods and cleaning the project, but it didn't work.
Now it's been solved after restart the system.
It's very simple. Add
#import <CommonCrypto/CommonCrypto.h>
to a .h file (the bridging header file of your project). As a convention you can call it YourProjectName-Bridging-Header.h.
Then go to your project Build Settings and look for Swift Compiler - Code Generation. Under it, add the name of your bridging header to the entry "Objetive-C Bridging Header".
You're done. No imports required in your Swift code. Any public Objective-C headers listed in this bridging header file will be visible to Swift.

Qt / QMake iOS Set Target, Device, other XCode settings

Qt for iOS creates an XCode project when you execute a build.
How does one dictate the XCode project settings from Qt to set a "target" (minimum iOS version) and "device" (Universal/iPhone/iPad), as found on the "General" tab in XCode when this project is opened?
I could not find this documented anywhere, but I figured it out.
In your qmake (pro or pri file) add these lines:
# Set "Target"
QMAKE_IOS_DEPLOYMENT_TARGET = 5.0
# Set "Devices" (2=iPad Only)
QMAKE_IOS_TARGETED_DEVICE_FAMILY = 2
Note for devices: 1=iPhone, 2=iPad, 1,2=Universal.
If you need to change other XCode project settings here's how you can:
After a build in Qt for iOS look at the "Compile Output" tab.
You will find a list of "export VARIBALE=some_value" entries.
To change one of these XCode build settings, simply use QMAKE_IOS_VARIABLE_NAME = my_value in your qmake.
For more info on these environmental varibles, check this out: Xcode Build Setting Reference
-- UPDATE --
I was wrong about the last part. You can't set all the XCode variables quite like that. If you output QMAKESPEC, however, you will get the path where you can find a qmake.conf file which will display some of these undocumented variables. Do so like this in your pro / pri:
message( $$QMAKESPEC )
That path will appear in the Qt console "General" tab when you build the project.
Here's an extended version I'm now using, with some logic for setting the build architectures:
greaterThan( QT_MAJOR_VERSION, 5 ){
DEFINES += QT_VER_5_4_OR_NEWER
}
else:equals( QT_MAJOR_VERSION, 5 ) &&
greaterThan( QT_MINOR_VERSION, 3 ){
DEFINES += QT_VER_5_4_OR_NEWER
}
contains(DEFINES, QT_VER_5_4_OR_NEWER){
DEFINES += SUPPORT_64_BIT_IOS
message( "SUPPORT_64_BIT_IOS" )
}
contains(DEFINES, SUPPORT_64_BIT_IOS) {
iosArchitectures="armv7 arm64"
iosTarget=5.1.1
}
else{
iosArchitectures=armv7
iosTarget=5.0
}
# Set "Architectures"
QMAKE_IOS_DEVICE_ARCHS = $$iosArchitectures
# Set "Target"
QMAKE_IOS_DEPLOYMENT_TARGET = $$iosTarget
# Set "Devices" (1=iPhone, 2=iPad, 1,2=Universal)
QMAKE_IOS_TARGETED_DEVICE_FAMILY = 2

Theos did not specify a target error

Trying to build a tweak using theos and having this error
/var/theos/makefiles/common.mk:103: *** You did not specify a target, and the "i phone" platform does not define a default target. Stop.
My Makefile is as shown
ARCHS = armv7 armv7s
SDKVERSION = 7.0
TARGET = iphone:7.0
include /var/theos/makefiles/common.mk
BUNDLE_NAME = sometweak
bustiming_FILES = Toggle.xm
bustiming_INSTALL_PATH = /Library/Application Support/CCToggles/Toggles
include $(THEOS_MAKE_PATH)/bundle.mk
Not sure what am I missing out, I've searched multiple websites and they said it's because of the missing TARGET in the Makefile however it's not working. Any advise is appreciated thanks.
Try
include $(THEOS_MAKE_PATH)/ instead of /var/theos/
Also try listing your Target as TARGET = iphone:latest:7.0
Finally, make sure before you use build, you have set the environment variables :-
export THEOS=/opt/theos
export THEOS_DEVICE_IP=192.168.0.2 (your phone ip)
export SKDVERVSION=7.0 (or whatever you are building for)
