How to customize build setting based on architecture in Xcode 7.2 - ios

I need to customize some build settings (namely linker flags) in Xcode based on whether the build is for architecture arm64 or armv7. I upgraded to Xcode 7.2 and it seems there is no longer this option:
As usual, you can expand any setting to see Debug and Release tabs, then if you click +, you will see pop up menu with Any Architecture|Any SDK on top, but inside the menu I only see options for different OSs and SDKs like iOS 9.2, Any iOS, Mac OS X, etc. I chose Any iOS since I need to support older iOS versions, but I don't see a way to choose arm64 and armv7, on which I need to customize.
Am I missing something, or did Xcode really remove this option now?
I suppose if this is no longer working, the only other way I see to customize is to create additional target, which is not very convenient.

One way you can do is to create a new xcconfig file for your target. (if you're using Cocoapods you might want to include it as well).
And then you can specify the architecture as well as the sdk for a build setting like this:
OTHER_SWIFT_FLAGS[sdk=iphoneos*][arch=arm64] = $(inherited) "-D" "COCOAPODS"

How to Update My Project Settings to Support iOS 5.1.1 or Later?

This has to be one of the simplest fixes. There must be something I'm just not seeing/getting.
I am in the process of converting my app to 64-bit so that I can deploy it to the app store. I got the warnings in my project and updated them like Xcode asks. However, I don't know how to update my project settings to support iOS 5.1.1. I just can't find that area.
I presume this is the reason why I cannot set my Architectures to “Standard Architectures (including 64-bit).” Instead, I only have the option of "Standard architectures (armv7, arm64) - $(ARCH_STANDARD)"
How do I resolve this?
Select your Project in the Project Navigator,
Select the Info tab, and then
Set the iOS Deployment Target to the version of iOS you want to target (in your case 5.1).
Im pretty sure that you can't simultaneously support 64-bit and pre-ios6...

Making Xcode ignore static library when building for iOS Simulator

I have a Xcode project, that includes a Static Library project, that uses another static library that does not support the iOS simulator architecture (Vuforia SDK: libQCAR.a).
Vuforia SDK documentation states:
Vuforia applications must be deployed to a device to run; they cannot be run in the iOS simulator.
This is my project structure:
MyApp.xcodeproj
Classes
MyStaticLibrary.xcodeproj
Classes that depends on libQCAR.a
Frameworks
libMyStaticLibrary.a
libQCAR.a
My problem is that MyApp.xcodeproj does not build for the iOS Simulator because libQCAR.a is not built for the i386 architecture.
Is there anyway to make MyApp.xcodeproj ignore the libQCAR.a library when building for i386? I would be able to disable all the code that depends on the library with #if !(TARGET_IPHONE_SIMULATOR)
You can use a conditional build settings to specify the library you want to link only on a given platform, instead of adding the library to your project in the usual ways. Specifically, you will need to specify:
-lQCAR
in "Other Linker Flags".
Have a look at the attached image that should make things more clear (in the picture I am linking only for the simulator, you will want to select a device, I guess).
Also, do not forget to add the path to the directory containing the library to "Library Search Path" build setting (this does not need to be conditional; it would not do any harm on the simulator).
This issue seems very similar to: Xcode: Conditional Build Settings based on architecture (Device (ARM) vs Simulator (i386))
I believe sergio's solution is very close, but have you tried specifying the full path to the library under Other Linker Flags (potentially without "-l" - just the path)?
In my case, it should specify clearly which SDK uses which flags.
So in Any iOS Simulator SDK, you should not include the library.
In Any iOS SDK, you should include it. In my case, it's -lCloudReco.

XCode 5 dependencies warning - confuses iOS deployment targets and architectures

I've searched here, read 9 answers that don't apply, validated my settings, checked them manually, cleaned, rebuilt and archived. I've also tried adding armv6 to Deployment Targets, same thing. The app runs fine on physical Iphone 4 and 5 devices, but I can't publish it...
Dependency Analysis Warning: iOS deployment targets lower than 4.3 are not supported (current IPHONEOS_DEPLOYMENT_TARGET = "4.0", ARCHS = "armv7").
(NOTE: After some thinking and testing, the basic problem is at the bottom of this question.)
Build Settings:
Architectures: Standard (armv7, armv7s)
Base SDK: Latest (iOS 7.0)
Supported platforms: iOS
iOS Deployment Target: iOS 5.1
Targeted Device Family: iPhone
Info.plist:
Iphone environment: Yes
no deployment target entry (which is what caused the warning in the linked answers)
But I still get the warning.
As you can see, this different from the Build Settings. I click the warning, but it doesn't tell me what could tell XCode to override the Build Settings, so I can do nothing about that.
How do I begin to fix this, where to look, what to check?
EDIT: In other words, this and this doesn't apply, since I don't build for deployment target lower than 4.3. I just need XCode to use the actual deployment target and architectures set in Build Settings.
UPDATE: So this is the issue I seem to be having: I added Required Device Capabilities armv7 (only) in the info.plist, and Apple forbids me to introduce such a requirement for apps that didn't have them (users couldn't upgrade). But then it would be nice of Apple to let me build for such users...
Unless it's just the bit about XCode not reading the targets right that prevents me from doing so.
--> So the question becomes: is there a way to force set IPHONEOS_DEPLOYMENT_TARGET to something >= 4.3?
There are couple of things you can do to see if this fixes your problem.
Do a clean build
XCode --> Product --> Clean
Close XCode
Go to your Derived data dir and remove everything from there
~Library~/Developer/Xcode/DerivedData
4- This maybe a redundant check. Though you have set your target to 5.1 check this anyways.
5- Launch Xcode and try your build again.
Even though I knew I hadn't typed the string IPHONEOS_DEPLOYMENT_TARGET in any of my sources, on a whim I searched for it in the project manager. Turns out that XCode does not use the settings displayed when clicking on the project in the project manager for compiling the app...
The only way I could get to the hidden setting that somehow overrode the visible setting was to click on the search result.
So, if you get this warning: iOS deployment targets lower than 4.3 are not supported, do this:
Cmd+Shift+F, search for IPHONEOS_DEPLOYMENT_TARGET.
Click search results with a target < iOS 5.0 (to go to the hidden Build Setting).
Set them to at least 5.0.
Note: Do not add armv6 to Architectures, set it to Standard (armv7, armv7s).

Possible Xcode Validate Settings Bug

I wrote an app originally for iOS 6, and I have since updated it to work on iOS 7. Now I want to build it to support the 64 bit iPhone 5s as well. In my project I switched the Architectures Build Setting to Standard architectures (including 64-bit) (armv7, armv7s, arm64). Upon build Xcode prompted me to validate my settings, and told me to let it automatically choose the architecture. I let it do this, however it switched it back to the default, Standard architectures (armv7, armv7s).
I looked for an answer on google but found no clear explanation.
I decided to ignore Xcode's warning, and fixed my app to support 64-bit and it built successfully (leaving the setting on Standard architectures (including 64-bit))
However I hated the feeling of going against Xcode's advice, so I created a new project as a test. I found that the default architecture build setting of a new project was Standard architectures (including 64-bit). I then clicked validate settings and found that even in this brand new project with nothing else changed, Xcode still wanted to change the architectures back to regular Standard architectures.
Is there a reason why Xcode is changing the architectures back, or is this a bug in the validate settings?

"Warning: iPhone apps should include an armv6 architecture" even with build config set

It's been a while since I've had to adjust project build settings. After upgrading to a recent SDK I'm having trouble building my ad hoc distribution configuration.
Build generates this warning and error:
warning: iPhone apps should include an armv6 architecture (current
ARCHS = "armv7")
iPhone/iPod Touch: application executable is missing a required
architecture. At least one of the following architecture(s) must be
present: armv6 (-19033)
However in my project I thought I had things set correctly:
Architectures is: Standard (armv6 armv7)
Base SDK: Latest iOS (currently set to iOS 4.2)
Valid Architectures: armv6 armv7
I have cleaned all targets.
I appreciate any tips.
If using Xcode 4.2 or higher, try the following:
Click your Project name (in the left column), followed by the Target:
Click the 'Build Settings' tab (in the right column):
Click the 'Release' or 'Distribution' row under 'Architectures', and choose 'Other...':
Double click the highlighted row named '$(ARCHS_STANDARD_32_BIT)' in the popover that appears, and replace it by typing 'armv6'. Then add a new row with the plus button in the bottom left of the popover, and type 'armv7', then click Done:
Update: you should add armv7s to target the iPhone 5 as well. (And drop armv6 if building with Xcode 4.5 or higher, which no longer supports armv6.)
That's it. You should now be able to build/archive without generating errors.
If it still doesn't work, see this answer from justinxreese, which suggests adding entries for armv6 and armv7 under "Required Device Capabilities" in your info.plist file.
If you uncheck "Build Active Architecture Only", then it will build all the valid architectures.
Update: This is no longer applicable as of Xcode 4 - follow Nick's instructions for Xcode 4 and later.
I had this problem even after following the accepted answer and found the following to work:
In your Info.plist, add an entry for Required Device Capabilities. This should be an array and will have two entries.
Item 0 : armv6
Item 1 : armv7
It will look like this:
In addition to Nick's answer about Xcode 4.2, you may also need to review your info.plist file. It seems as if new projects started in Xcode 4.2 by default specify 'armv7' in the 'Required Device Capabilities'. You'll need to remove this if wanting to support devices that run armv6 (e.g. the iPhone 3G).
Delete armv7 from the 'Required device capabilities' in yourProjectName-Info.plist
An ios 6 update
Changes in Xcode 4.5.x for ios 6
Xcode 4.5.x (and later) does not support generating armv6 binaries.
Now includes iPhone 5/armv7s support.
The minimum supported deployment target with Xcode 4.5.x or later is iOS 4.3.
I had this problem too. I just set my deployment target to 4.3 and left only armv7 architecture and it worked. At point almost everyone has 5, so 4.3 is fine.
for me it not work with every answer. but I try TARGETS > Architectures > Debug and add a new row with the plus button, and type 'armv6'(with out '), then click Done.
and finally CMD+B and then right click at PrjectName.app(in Products folder) > Open in Finder > Compress "PROJECT_NAME.APP" (in Debug-iphoneos) > Upload to AppStore
it's my screen setting.
if you have include project please config it all.
Hope your help.
After trying a mixture of these answers, I finally stumbled across making it work. Im so pissed off at Apple right now. Just another hour they made me waste. Here is my config.
I tried all the answers above ,none resolved my question. So I create a new project and diff the build settings one by one. Only "Alternate Permissions Files" is different.
The project build failed has a value armv7. Delete it then clean->build->archive . Succeed!
Hope can solve you question
Wow, I update/submit apps about every 6 months. Every time I do this I have to learn the "new" way to do it...
Same problems as described above when running iOS 5.1, and Xcode 4.3.2
Thanks for the posts! I spent a while updating all of the project settings to armv6, armv7, but no joy. When I set "build active architecture only" to No I got a build error about putting both objects in the same directory.
Fortunately, I noticed you guys were modifying the target build settings instead. This is what finally worked (armv6, armv7, and setting "build active architecture only" to No under the Target build Settings). As a disclaimer, I had already set all of the architectures to armv6, armv7 in the project settings too.
Anyway, thanks for the help,
Brent
I had to be sure to change these settings in both the Target and Project settings on xCode 4.3.2 after doing that and setting it to build for both armv6 and armv7 everywhere I was able to submit my app.
For safe measure I also exited xCode between making the changes and doing a clean, build, archive cycle.
Quite a painful problem for me too. Just spent about an hour trying to build and re-build - no joy. In the end I had to do this:
Upgrade the base SDK to the latest ( in my case iOS 5 )
Restart xCode
Clean & Build
It worked!
I guess it's a bunch of jargon about arm6 , arm7 as it looked like my project was valid for both, at least the settings seemed to say so ) , my guess is this is a cynical way to bamboozle us with the technicalities, which we don't understand, so we just take the easy option and target the latest iOS ( good for Apple with more people being up-to-date ) ....
Here is Apple's documentation:
Technical Q&A QA1760
It says there are two things that you must get right:
Add armv6 to the Architecture build settings
Set Build Active Architecture Only to No.
If this still doesn't help you, double check that you are really changing the architecture build settings for the right build configuration – I wasted half an hour fiddling with the wrong one and wondering why it didn't work...
Select Edit Scheme... in the Product menu, click the "Archive" scheme in the left list and check the Build Configuration. Change the value if it was not what you expected.
Note; I had to perform these steps for both my base project, and the embedded PhoneGap .xcodeproj file in my application.
Yes, I embed PhoneGap; they update far to frequently, and I've got less than two months to know that a feature is depreciated.
Try changing your deployment target to something higher than an armv6 processor. The settings for xCode are referencing the operating system level, for instance: iOS version#{3.1, 3.2, 4.0, 4.1, 4.2, 4.3, 5.0, 5.1}
(i)You can set this in the build settings tab or the summary tab. Start at the top left of the window in the Project Navigator, with all the files listed in it. Click the top-most one which has a blue icon.
(ii)If you are planning on using the programmable shader line circuitry, which is accessed and controlled through openGL ES 2.0 API, then you should set your "Deployment Version" to about 4.3, which I believe is only available on devices such as the 3GS or newer. xCode is reporting that iOS 4.2.5 or higher is needed run armv7 code. And once again, this processor, I believe, started with the 3GS.* iOS 4.3 seems to be the choice for me, for now.
http://theiphonewiki.com/wiki/index.php?title=Armv7
http://en.wikipedia.org/wiki/List_of_iOS_devices
If xCode keep complaining about armv7, make sure you disconnect any connect device (especially iPhone 5!!) and try again. Took me hours to find out that little piece of information.
Using Xcode 4.2 on Snow Leopard, I used the following settings to build an app that worked on both armv6 (Iphone 3G and lower) AND armv7 (everything newer than 3G including 3GS).
architectures: armv6 and armv7 (removed $(ARCHS_STANDARD_32_BIT))
build active architecture only: no required device capabilities:
armv6
do not put armv7 in required device capabilities if you want the app to run on 3G and lower as well.
