Was building fine until beta3. 0 comments 0 Copy to clipboard Share this post Copied to Clipboard Load more Add comment wongfrompalmyrau OP Aug ’20 Can some guys of the Xcode team pay attention to this issue? This issue has appeared since Beta2. And I downloaded the latest Beta 5 still not work!!!!!!!! 0 comments 2 Copy to clipboard Share this post Copied to Clipboard Load more Add comment Engineer OP Apple Aug ’20 You haven't provided much information here so I can only make guesses. This might be caused by a project mis-configuration. If you were previously overriding the default value for build architecture please reset that to the default setting "$(STANDARD_ARCHS)".If you are building from the command line try giving xcodebuild the generic simulator destination. If that doesn't help please file a feedback item so we can investigate. It will help if you can provide your entire build log. You can also create a new project from a template and compare build settings between the two to attempt to narrow down what is misconfigured in your project. 0 comments 0 Copy to clipboard Share this post Copied to Clipboard Load more Add comment pak.support OP Aug ’20 You can easily check the problem with the below environment variables,Code Block

$ARCHS

$ARCHS_STANDARD

$ARCHS_STANDARD_32_64_BIT

$ARCHS_STANDARD_64_BIT

$VALID_ARCHS

Problem

We can able to resolve the problem with the help of hardcode the Standard Architecture to x8664 and Valid Architecture to x8664 for both Library Xcode project(It used for build the static library) and Application generate Xcode project(Used for generate the application). But the trouble is we are using the same project for both iOS Simulator and iOS Device building. So we can't go with the hardcoded value.

Analysis

For this issue please find my analysis, if anything wrong please correct me.I have checked the below environment variables in both Xcode11 and Xcode12 while building the library for iOS Simulator and I found the arm_64 appended in all the environment variables in Xcode12.

Xcode 11 Environment Variable values:

Code Block

export ARCHS="i386 x86_64"

export ARCHS_STANDARD="i386 x86_64"

export ARCHS_STANDARD_32_64_BIT="i386 x86_64"

export ARCHS_STANDARD_64_BIT=x86_64

export ARCHS_STANDARD_INCLUDING_64_BIT="i386 x86_64"

export ARCHS_UNIVERSAL_IPHONE_OS="i386 x86_64"

export VALID_ARCHS="i386 x86_64"

Xcode 12 Environment Variable values:

Code Block

export ARCHS\=arm64\ i386\ x86_64

export ARCHS_STANDARD\=arm64\ i386\ x86_64

export ARCHS_STANDARD_32_64_BIT\=arm64\ i386\ x86_64

export ARCHS_STANDARD_64_BIT\=arm64\ x86_64

export ARCHS_STANDARD_INCLUDING_64_BIT\=arm64\ i386\ x86_64

export ARCHS_UNIVERSAL_IPHONE_OS\=arm64\ i386\ x86_64

export VALID_ARCHS\=arm64\ i386\ x86_64

Could you please provide your quick suggestion?Note:

1. The above information is not help then i will file feedback request.

2. Above environment variable copied from my build log file.

If yes, what's the exact value to be set? I just tried with "arm64", no luck. 0 comments 0 Copy to clipboard Share this post Copied to Clipboard Load more Add comment pak.support OP Sep ’20 Any update? 0 comments 0 Copy to clipboard Share this post Copied to Clipboard Load more Add comment asengupta OP Sep ’20 I filed a Feedback regarding this and Apple closed it saying it is an expected behavior without any proper clarification.
