💻 GoogleMobileAds 8.1 crash on iOS 13 sumulator and Apple Silicon M1

Hi @Koze . I found the new problem 🤔 This issue is not spm related, but I would like to get confirmation from other developers.

GoogleMobileAds 8.1 crash on iOS 13 sumulator if you use Apple Silicon M1 processor.

Thread 1: EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0)

The crash points to the AppDelegate class but the problem is in GADMobileAds.sharedInstance().start(). If you remove this method, the crash disappears.

Can you confirm or deny the problem?

I have created topic on google developer forum: https://groups.google.com/g/google-admob-ads-sdk/c/ulno5g6X9IA

@mezhevikin I found a simple workaround. Setting any of the following diagnostic options in the scheme settings will prevent the crash.

• Address Sanitizer
• Thread Sanitizer
• Malloc Scribble
• Malloc Guard Edges
• Guard Malloc
• Malloc Stack Logging

I verified this with Xcode 12.4 (12D4e), iOS 13.7 Simulator, macOS Big Sur 11.2.3（20D91） and M1 Apple Silicon Mac.

@mezhevikin According to my investigation, it has nothing to do with AdMob, xcframework, or SPM. The crash seems to be caused by a combination of Xcode 12, iOS 13 Simulator, Big Sur, and M1, even when using only system frameworks.

Please try my workaround. Thanks,

Hi @Koze . I tried your workaround and it works perfectly. Thank you. I sent this information to Admob Team. I think it will be helpful in any case.

Additional information: This workaround works for iOS13 simulator, but does'n work for iOS 12.4 simulator.

does'n work for iOS 12.4 simulator

I hope this will be fixed in a future version of Xcode.
