@DTS Engineer We have similar issues any insight about that crash or how to prevent it. In our case we have the following stack trace: What the OUTLINED_FUNCTION means ? how it can be prevented? 0 libswiftCore.dylib 0x37445c __swift_allocate_boxed_opaque_existential_0 + 28 1 libswiftCore.dylib 0x1797d4 swift_getAtKeyPath + 100 2 SwiftUI 0x5a6520 OUTLINED_FUNCTION_23 + 532 3 SwiftUI 0x244114 OUTLINED_FUNCTION_651 + 88 4 SwiftUI 0x17c394 __swift_memcpy25_8 + 2024 5 SwiftUI 0xce172c OUTLINED_FUNCTION_12 + 1084 6 SwiftUI 0xce19c8 OUTLINED_FUNCTION_12 + 1752 7 SwiftUI 0x7a7538 OUTLINED_FUNCTION_28 + 3104 8 SwiftUI 0x15dc268 OUTLINED_FUNCTION_39 + 6700 9 SwiftUI 0x15de2ac OUTLINED_FUNCTION_39 + 14960 10 SwiftUI 0x15de308 OUTLINED_FUNCTION_39 + 15052 11 Pendo 0x13d5bc UIView.extensionMethod() + 5364 12 Pendo 0x13d620 @objc UIView.extensionMethod() + 5464

We see the similar logs on just iOS app

@DTS Engineer you have mentioned the issue under the following ticket: (r. 32863680). Do we as developers have the right to access that ticket? For instance the following http://www.openradar.me/32863680, http://www.openradar.me/FB32863680 Doesnt lean to anything, my guess is that its internal apple issues, can you please confirm

My issue was not matching deployment targets between extension and hosting app

I have the same issue @DTS Engineer was it resolved, if yes any insight on what was wrong?

@App Review I have tried to schedule a meeting but was rejected in the end Amy chance we can answer the question in the thread so it will be also visible for other developers?

@App Review Yes I still need a help with that question where in this link: contact us I should update my phone number? I used Membership & Account -> Account Information update and send you a message with my phone number

We need build a xcframework if I build it with new Xcode version and the app is build with old Xcode version that will not work

@DTS Engineer Okay, so Xcode 15 SDK builds on Sequoia won't work for clients on older Xcodes, That's a major problem due to Swift forward incompatibility. Any workarounds? Can we use xcode-select with an older Xcode install on Sequoia for CLI builds? will that work?

Same issue on Xcode 16.4 and Xcode 26

Same issue

I was using OCmock for my tests and after rebuilding it with same Xcode version as all my other libs the coverage started to generated.

Hi @tattooedDev Thanks for your help. We have already opened a similar issue with apple here: https://developer.apple.com/forums/thread/814208 And also contacted them via TSI. Lets follow it from one source (to prevent confusion if you dont mind)

@DTS Engineer We have just submitted: FB21851974 Thanks

@DTS Engineer Any minimal insight you can share or how to avoid it ?
