SwiftUI Hello World app wouldn't build with SDK version 2.4.1

[nivbp7]

Hello,
I've created a new Xcode project. I've selected SwiftUI as the interface.
I've added the TelemetryDeck SDK, as described in this guide, where the Dependency Rule is set to Up to Next Major Version and the selected version is 2.4.1 release link.
Doing just that (not even importing TelemetryDeck to any file or Initializing the package, and the app fails during the build phase.
The failure is in the TelemetryClient file, in this line:

nonisolated(unsafe)

nonisolated can not be applied to stored properties

If I change the Dependency Rule to Exact Version and the selected version 2.3.0, the app can be built and run.

My setup:
Xcode: Version 15.0.1 (15A507)
macOS: 13.6 (22G120)
mac: MacBook Pro 13-inch, 2020, Four Thunderbolt 3 ports, 2 GHz Quad-Core Intel Core i5
simulator: iPhone 13 Pro, iOS 17.0.1

Same issue with version 2.5.0

Thank you for reporting this. I just investigated and found that the nonisolated(unsafe) was introduced via SE-412 in Swift 5.10, which shipped in a later version of Xcode. Unfortunately, later versions don't show that this was missing in Swift 5.9 even though the SDK defines Swift 5.9 as its target.

I rewrote the code to use a different approach without making use of nonisolated(unsafe) so we can reinstate support for Swift 5.9. Just waiting for #207 to get merged, should be fixed in the next update!

@nivbp7 @gparadelo I'm happy to inform you that the fix is now part of the new SDK release 2.6.0.

Please give it a try and let me know if you run into any issues! Thank you again for reporting this. 🙏
