Migrating to Xcode 13.1 toolchain has caused a crash on device builds. No crash happen on simulator builds. Some build settings for device builds Optimised for size wmo enabled LTO - incremental We didn't manage to reproduce the crash on a example app after multiple attempts. ``` Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libswiftCore.dylib 0x00000001a6e16c3c swift_getAssociatedTypeWitnessSlowImpl+ 3767356 (swift::MetadataRequest, swift::TargetWitnessTable<swift::InProcess>*, swift::TargetMetadata<swift::InProcess> const*, swift::TargetProtocolRequirement<swift::InProcess> const*, swift::TargetProtocolRequirement<swift::InProcess> const*) + 352 1 libswiftCore.dylib 0x00000001a6e16c34 swift_getAssociatedTypeWitnessSlowImpl+ 3767348 (swift::MetadataRequest, swift::TargetWitnessTable<swift::InProcess>*, swift::TargetMetadata<swift::InProcess> const*, swift::TargetProtocolRequirement<swift::InProcess> const*, swift::TargetProtocolRequirement<swift::InProcess> const*) + 344 2 libswiftCore.dylib 0x00000001a6e14b3c swift_getAssociatedTypeWitness + 236 3 libswiftCore.dylib 0x00000001a6bff6cc _SwiftNewtypeWrapper<>._rawHashValue+ 1574604 (seed:) + 72 4 <redacted> 0x0000000104f22e5c protocol witness for Hashable._rawHashValue(seed:) in conformance AVMetadataObjectType + 13102684 (<compiler-generated>:0) 5 libswiftCore.dylib 0x00000001a6b46968 __RawDictionaryStorage.find<A>+ 817512 (_:) + 56 6 libswiftCore.dylib 0x00000001a6d9d688 specialized Dictionary.init+ 3270280 (dictionaryLiteral:) + 796 7 libswiftCore.dylib 0x00000001a6ad6d54 Dictionary.init+ 359764 (dictionaryLiteral:) + 24 8 <redacted> 0x000000010a76a090 specialized <redacted>.<redacted>() + 105668752 (<redacted>.swift:38) 9 <redacted> 0x000000010a76984c one-time initialization function for headline + 32 10 libdispatch.dylib 0x00000001a2b0381c _dispatch_client_callout + 20 11 libdispatch.dylib 0x00000001a2b050b4 _dispatch_once_callout + 32 12 libswiftCore.dylib 0x00000001a6e3397c swift_once + 48 13 <redacted> 0x000000010a7696a8 <redacted>.caption.unsafeMutableAddressor + 105666216 (<redacted>Font.swift:103) 14 <redacted> 0x00000001044069b4 <redacted>().init() + 1452468 (<redacted>swift:58) 15 <redacted> 0x0000000104406f84 @objc <redacted>().init() + 1453956 (<compiler-generated>:0) 16 <redacted> 0x00000001044061d4 one-time initialization function for shared + 1450452 (<redacted>swift:65) 17 libdispatch.dylib 0x00000001a2b0381c _dispatch_client_callout + 20 18 libdispatch.dylib 0x00000001a2b050b4 _dispatch_once_callout + 32 19 libswiftCore.dylib 0x00000001a6e3397c swift_once + 48 20 <redacted> 0x000000010442d444 closure #1 in <redacted> + 1610820 (AppDelegate.swift:117) 21 <redacted> 0x000000010442ba80 <redacted> + 1604224 (<compiler-generated>:0) 22 <redacted> 0x0000000104495a1c specialized <redacted>.init(<redacted>::) + 2038300 (<redacted>.swift:246) 23 <redacted> 0x0000000104493248 one-time initialization function for shared + 2028104 (<redacted>.swift:216) 24 libdispatch.dylib 0x00000001a2b0381c _dispatch_client_callout + 20 25 libdispatch.dylib 0x00000001a2b050b4 _dispatch_once_callout + 32 26 libswiftCore.dylib 0x00000001a6e3397c swift_once + 48 27 <redacted> 0x00000001042f40d4 AppDelegate.<redacted>() + 327892 (<redacted>.swift:800) 28 <redacted> 0x00000001042f40f0 @objc AppDelegate.<redacted>() + 327920 (<compiler-generated>:0) ```
