Actual results

Hi!

Short: Our game crashes on launch on iOS 13.1.3 with FB SDK 17.0.1 and 17.0.2.

Log:

May 22 16:38:45 iPhone-XS-QA MyApp(CoreFoundation)[387] : Error loading /var/containers/Bundle/Application/99834DD0-4983-46BC-A990-0725895ABFC2/MyApp.app/Frameworks/UnityFramework.framework/UnityFramework: dlopen(/var/containers/Bundle/Application/99834DD0-4983-46BC-A990-0725895ABFC2/MyApp.app/Frameworks/UnityFramework.framework/UnityFramework, 0x0109): relative file paths not allowed '@rpath/libswiftXPC.dylib'

More info:

The case is 100% reproducible on iOS 13.1.3 with FB SDK 17.0.1+
FB SDK v17.0.0 is fine, no crash. The older versions don't crash either.
Device: XS Max
We don't see the crash on more recent major versions of iOS, like 14, 15, 16, 17 - they're OK.
We tested it with an empty project. Only the FB SDK was integrated. So there was no interference from other SDKs.
We only have one device with iOS 13. We don't know how many old versions are affected. Interestingly, this message may indicate that there is no crash on iOS 13.4.1

Our game supports iOS 12+. Since the v17.0.1+ is mandatory because of the Apple Privacy Manifest support, we are going to ship an update soon knowing some of our users, including payers, won't be able to launch the game which is unfortunate.

Steps to reproduce

Build an iOS app with FB SDK v17.0.1+
Try to launch it on iOS 13.1.3 Some other older iOS versions may be affected too.

Code samples & details

// A podfile from the empty test project:

source 'https://cdn.cocoapods.org/'

platform :ios, '12.0'

target 'UnityFramework' do
  pod 'FBSDKCoreKit', '17.0.2'
  pod 'FBSDKCoreKit_Basics', '17.0.2'
  pod 'FBSDKGamingServicesKit', '17.0.2'
  pod 'FBSDKLoginKit', '17.0.2'
  pod 'FBSDKShareKit', '17.0.2'
end
target 'Unity-iPhone' do
end

swiftXPC require iOS17.4+, iOS17.4+ require XCode15.3 So, you need upgrade XCode version to 15.3 to resolve this problem.

Info from follow links:

You can follow my step to find why it happen :

download & unzip firebase ios sdk
Go to folder where contain FBAEMKit
ar -x FBAEMKit non-fat file, you can get many .o file
use nm -u *.o to check link symbol .

follow log is some of my result , you can find __swift_FORCE_LOAD_$_swiftXPC

I am using Xcode15.3 and Xcode15.4 and this crash still occurs on iOS13.1.2 devices
