3. Steps to reproduce, with a description of expected vs. actual behavior

This is happening during app launch, so not much I can do.

👀 We've just linked this issue to our internal tracker and notified the team. Thank you for reporting, we're checking this out!

[fishandphil]

I believe that we're getting a similar crash at launch with Xcode 16 beta.

[MarkVillacampa]

Hey @fishandphil @eklipse2k8 thanks for your reports!

We're aware of this issue and already filed FB13828346 with Apple.

The issue seems to manifest only when compiling with Xcode 16, and running on iOS 17/macOS 14.

We're trying to find a workaround while Apple gets back to us. We'll keep you posted.

Meanwhile, you can test your apps by running on an iOS 18 simulator or device.

Sorry for the inconvenience!

[YiLee01]

The same issue also appears on devices running iOS 15.

[MarkVillacampa]

Filed an issue in the Swift repo:

https://github.com/apple/swift/issues/74333

[xAstralMars]

got the same issue with both iOS 18 beta and iOS 17.4. seems like it doesn't point to the code that crashed on 18.0 beta, only on the iOS 17 emulator

[mos-stuartpatt]

Is there a known version of the SDK that we know isn't having this issue? Seeing this on 17.4 also

[xAstralMars]

Is there a known version of the SDK that we know isn't having this issue? Seeing this on 17.4 also

it's on anything prior to ios 18 beta on Xcode 16 beta. the only version that works is ios 18

[roddymunro]

Confirming that this is still an issue on Xcode 16 beta 2.

[Melber17]

The same

[ekurutepe]

Are there any plans for a workaround, just in case the Swift bug is not fixed swiftly enough?

Edit: it seems like it's fixed already https://github.com/swiftlang/swift/issues/74333#issuecomment-2195013992

[VatanaChhorn]

Installed release/6.0 (June 22, 2024), and the crashes are still there.
