I'm trying to upload to TestFlight a project build for arm64, armv7, and armv7s. It is using a framework from another project. But the frameowork appears to be built only for arm64 and not arm64 (file was built for arm64 which is not the architecture being linked (armv7)).
The question is how do I make the framework containing all architectures? I want to keep the projects separated. And I don't care for simulators. I want to make sure it is built for release.
This is the framework target:
EDIT: My project is Cordova based. So it is using a plugin which utilize a pre-built framework. There are instructions out there for building a fat framework, containing simulators and device, then concatenating it with lipo. What I need is the architecture from the device I don't have as well. Does that actually mean I need three devices from arm64, armv7, and armv7s to be able to concatenating them altogether?
Apple has discontinued support for 32-bit in iOS 11. You can neither run 32 bit apps on iOS 11 nor run iOS 11 on 32 bit processors. Thus, you have to set your Deployment Target to an iOS version earlier than iOS 11 for your framework.
You can try to create an aggregate target and write an script which will support all the platform. This is sample script from one of my project.

I am having this error in my Xcode project....So basically what I am doing is creating a static library that uses a Swagger Api that I have installed using CocoaPods. I am able to import the header files and use the header files in the library, but when I put the static library in another Xcode project I receive this error where It says _OBJC_CLASS_$_SWG....", referenced from: objc-class-ref in Sendable.o.... which is basically the class where I am using the Swagger header files.....
Things I have attempted:
1: Delete Derived Data folder, cleaned and rebuilt
2: made sure POD, library, and project using library have the same architectures as well as
3: made sure architecture build active is set to NO for all
4: made sure $(inherited) is in both library and project using library
5: installed pod file again in library
Things I noticed:
1: the library itself does not have POD in the header search path
2: I get the following warnings but ignored them
3: using Pod update gives me error saying GitHub is offline make sure you have internet connection, only removing and installing seem to work successfully.
My guess is that you are building the library for a single architecture - you are building it either for a Generic iOS Device, or some speciffic iOS device. Either way, you will not be able to use the library on a simulator (x86_64 architecture). Vice versa, if you build the library for a simulator, you will not be able to use it on a device.
If you want to use the same build on both devices and simulator, you need to create an universal library using a tool called lipo, either manually or by Build Phase script. Check out this article. Short summary:
Add an Aggregate target to your library project
Add a Run Script Build Phase
Paste this script into it:
# define output folder environment variable
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# Step 1. Build Device and Simulator versions
xcodebuild -target ${PROJECT_NAME} ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
xcodebuild -target ${PROJECT_NAME} -configuration ${CONFIGURATION} -sdk iphonesimulator -arch x86_64 -arch i386 -arch armv7 -arch armv7s -arch arm64 BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Step 2. Create universal binary file using lipo
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/lib${PROJECT_NAME}.a"
echo "Universal library can be found here:"
echo ${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a
# Last touch. copy the header files. Just for convenience
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/include" "${UNIVERSAL_OUTPUTFOLDER}/"
Build your Aggregate target and an universal library will be built
I am creating Framework, I used aggregate target in that framework where we can write shell script to Build the framework for device as well as simulator based on script based on that i will have executable framework that can be imported in any project and we can use that class and method of framework.
But issue is that when we create executable framework with "schema device" then i can able to run on all device but if i make build using particular iOS5/iOS6 simulator then it will run only selected iOS5/iOS6 simulator in client project.
if i have created framework build using iOS5 simulator and if i run that framework in client project and i used iOS6 simulator it gives Undefined symbols for architecture x86_64.
I need shell script which support both architecture i386 and x86_64 means my framework should be executable for all device and all simulator in client project.
Any insights into this would be really helpful.
Create aggregate target and inside its Build Phases -> Run script write script to:
Build 2 separate frameworks:
1. Framework with architectures for mobile devices (armv7, arm64, etc.)
2. Framework with architectures for simulator (i386 and x86_64).
For example:
xcodebuild -workspace MyApp.xcworkspace -scheme MyFrameworkScheme -arch i386 -arch x86_64 ONLY_ACTIVE_ARCH=NO -sdk iphonesimulator -configuration ${CONFIGURATION} clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphonesimulator BUILD_DIR=${BUILD_DIR}
xcodebuild -workspace MyApp.xcworkspace -scheme MyFrameworkScheme -arch armv7 -arch armv7s -arch arm64 ONLY_ACTIVE_ARCH=NO -sdk iphoneos -configuration ${CONFIGURATION} clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphoneos BUILD_DIR=${BUILD_DIR}
Then, use lipo to merge the libraries inside both frameworks to a fat library, and replace one of them inside the framework => you have a fat framework.
I need to build dynamic library as framework. I have building settings as follows:
ARCHS: armv7 armv7s arm64 i386 x86_64
ONLY_ACTIVE_ARCH: NO
VALID_ARCHS: arm64 armv7 armv7s x86_64 i386
I built target for ios device, and used lipo -info to check the architectures, the result is :
Architectures in the fat file: dyl are: armv7s armv7 arm64
So, does xcode can not build for both i386 and arm?
You need to select iOS simulator and build a framework for i386 arch. Then you can use lipo -create command to merge the two framework into one.
There is a way of doing it without exiting the Xcode. First you need to identify the latest iOS versions (64 bits) do not support i386 architecture. So if you still need i386 compatible framework, you have to build your project by selecting an old iOS version. I tried with iOS 10.
Next thing that you have to do is, add all the architectures that you need under Valid Architectures filed in the Build Settings.
Then, add a Run Script with your lipo commands to create the FAT file. (Following script I've taken from the Internet sometime back & credit goes to those who wrote that)
#!/bin/sh
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Step 1. Build Device and Simulator versions
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"
# Step 3. Copy Swift modules from iphonesimulator build (if it exists) to the copied framework directory
SIMULATOR_SWIFT_MODULES_DIR="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/."
if [ -d "${SIMULATOR_SWIFT_MODULES_DIR}" ]; then
cp -R "${SIMULATOR_SWIFT_MODULES_DIR}" "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
fi
# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"
# Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"
# Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"
Finally what you have to do is, build the framework by selecting Generic iOS Device option.
Then to verify, run the lipo -info command
Few days ago i create static-library (Universal) that work's fine with Xcode5.0 SDK7. After Update Xcode5.1 with SDK7.1 that not work if i select simulator iPhone Retina(4-inch 64-bit). Then i am going to update my lib with Bellow setting change.
I do the same for three Target:-
For sporting simulator as well as device i put Universal lib and in to this i run script this:-
After this i Build Again lib and used as i done Before in to my project. But still getting same issue with iPhone Retina(4-inch 64-bit) Undefined symbols for architecture x86_64:
So, My question is that is there any additional change required for updating lib for arm64 or i did any mistake in above step. Please current me if i am wrong.
what change needed for update my static-library for supporting 64Bit architecture
NOTE:
I am asking for my own created Library Update. i am not using third-party Library.
Update
I used this lipo -info testingLibImport/libLibNSlog.a command in to my Terminal that output is:
Architectures in the fat file: testingLibImport/libLibNSlog.a are: armv7 armv7s i386 arm64
Another solution I found with XCode 6.4 is to add ONLY_ACTIVE_ARCH=NO and not specify the architecture. So
xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphonesimulator BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
Will build i386 and x86_64 architectures in your library.
Here's my full universal lib run script to build all the architectures.
# define output folder environment variable
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# Step 1. Build Device and Simulator versions
xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphonesimulator BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Step 2. Create universal binary file using lipo
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/lib${PROJECT_NAME}.a"
# Last touch. copy the header files. Just for convenience
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/include" "${UNIVERSAL_OUTPUTFOLDER}/"
I too ran into the same problem yesterday and after lot of googling and trying on different solutions, i gave up and tried on my own. All i could understand from the different solutions provided was that when i run "lipo -info library.a" it was not built for x86_64 architecture. So, decided to give up the aggregate approach and made a simple attempt.
as advised in this post, i added armv7, armv7s and arm64 to the architectures.
build the static library project with iphone simulator (32 bit)
build the static library project with iphone simulator (64 bit)
build the static library project with iOS device
go to the build path (under derived data)
copied both simulator and device output to a common folder
used lipo command in terminal window to create the universal library
lipo command: lipo -create -output newlibraryname.a simulatorlibraryname.a devicelibraryname.a
integrated the newly created universal static library and it WORKED!!!
After lots of stuff i got solution. some of xcode dont know there is automatic appear Standard architectures (including 64-bit) (armv7,armv7s,arm64) but in my case there is not option into my Static Library Project. so i am going to add this Manually like:-
and select this Option:-
After this i re-Build My static Library and used in to in my project that working fine now. and I also checked with lipo command in to terminal that output going to different now:-
testingLibImport/libLibNSlog.a are: armv7 armv7s i386 x86_64 arm64
Sorry for posting another solution so late. I had found this solution long time back when i was trying to find a solution that would save me from the manual work of creating a universal library using lipo command every time i had to build the universal library.
So, here is the another approach, for those using aggregate approach to build the universal library
just make one small change as mentioned below in your aggregate script for simulator to build the universal library -
xcodebuild -target ProductName -configuration ${CONFIGURATION} -sdk iphonesimulator ARCHS="i386 x86_64" BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" SYMROOT="${SYMROOT}"
Please observe the inclusion of multiple architectures instead of using single architecture approach -
xcodebuild -target ProductName -configuration ${CONFIGURATION} -sdk iphonesimulator -arch i386 BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" SYMROOT="${SYMROOT}"
Just ARCHS="i386 x86_64" will do the magic for you.
You can confirm this by using the following lipo command
lipo -info newLibraryName.a
Hope this saves time for many others like me!!!
i am new to Apple iOS development. I am trying to create static library and add it to Main application.
Created Library Project and added it as a dependency project to the Main application. It works.
Now I took the lib.a (static library) from the Library project (present under debug-iphoneos) and copied to Main application. Tested the Main application - it works.
Now when i tried to copy the Main application to some other location (or even change the folder name - in which Main application is present) and try to run on Simulator, then i get following error:
ignoring file /Users/.../lib.a, missing required architecture i386 in file /Users/.../lib.a
I don't really understand the relation/dependency on the path.
the problem is solved.
I am using XCode 5.0.2 and iOS 7. when ever i compile the static library, the Xcode says it is building a universal library (but it is actually not). The 'Products' directory shows libxyz.a (which is in iphoneos/ directory) - this is actually for ARM6 & ARM7 for iPhone device. So when i took this 'libxyz.a' file and used it in another projects the linker used to throw a warning ' missing required architecture i386 '.
i have followed http://www.raywenderlich.com/41377/creating-a-static-library-in-ios-tutorial
used the script to generate single binary which contains both simulator & iphone device binary.
# define output folder environment variable
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# Step 1. Build Device and Simulator versions
xcodebuild -target ImageFilters ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
xcodebuild -target ImageFilters -configuration ${CONFIGURATION} -sdk iphonesimulator -arch i386 BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"
# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Step 2. Create universal binary file using lipo
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/lib${PROJECT_NAME}.a"
# Last touch. copy the header files. Just for convenience
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/include" "${UNIVERSAL_OUTPUTFOLDER}/"
