Thank you for looking into this!

Seems like we also need to update the Snapshot tests & other functionality to reflect the concurrency change to make the PR mergable

[Supereg]

@PSchmiedmayer the Snapshots test are failing within the CI. If you look at the xcresult bundle, the snapshot images don't differ though. I couldn't reproduce the failure locally. I also tried to regenerate the images (they resulted in the exact same binary representation).

@Supereg As noted on Slack: I unfortunately don't have a clear idea where this might come from, let me know if you want me to dig deeper into this!

Maybe we can wait for Xcode 16 beta 4 release today and see if that changes anything? Otherwise, let's discuss other strategies in the meeting later.

@Supereg I have just installed the Xcode 16 Beta 4 on all macOS runners that we host.

Just resolved the issue. It seems there is a difference, if the snapshot tests are run on the iOS 18 simulator vs on an iOS 17.5 simulator. The iOS 18 simulator slightly changes shadows around text which made all of the snapshot testing fail. This is now resolved.

I added some additional minor changes to the PR, like improving Sendable annotation of ValidationRule, allow arbitrarily built Regex instances with ValidationRule and slightly improving flexibility of the VerifiableTextField. I re-requested a review to cover those changes 👍
