Hi @luionTW, our current builds all seem to pass on the GitHub Action runners. Can you check which Xcode version and macOS version you are using? Please ensure that you use the latest versions. Our CI should catch any build errors but there might be configurations that we are missing and might need to add based on your feedback.

If it is an underlying bug in SpeziViews, can you try to replicate it in the other repository while also ensuring that you are using the latest Xcode version? Feel free to move the issue to SpeziViews if it is more applicable there.

Hi @PSchmiedmayer ,

Thanks the information.

I noticed that the Xcode version in GitHub Actions is 16.0.1, while I am using Xcode 16.2 beta and an iPhone 15 Pro. I am not sure if this is the root cause.

Thank you for the additional context; it might be that the Xcode 16.2 beta could have changed some Swift behavior; can you try to reproduce the error in Spezi Views and see if there is a quick fix for the underlying issue?

Happy to see a PR that fixes this in time for Xcode 16.2 to be released 👍

Hi @PSchmiedmayer,

Here are the steps to reproduce the issue in the SpeziView repo:

• Open the Tests project in Xcode 16.2 beta and compile it.
• The error will be triggered immediately.

I am working on a fix, but it causes multiple dependency errors. Thank you.

Capture of 'state' with non-sendable type 'ValidationState.Binding' in a @Sendable closure

Can confirm this is a problem in Xcode 16.2. Swift 6 concurrency issues with non sendables crossing actor boundaries in several places
