Hi,

I am running Xcode Beta Version 15.0 beta 3 (15A5195k)

With my test Apps I am now getting the error Failed to Build the Scheme when trying to use the Canvas.

The Apps all compile and run both in the Simulator and on an external device such as my iPhone,

Error details below..

Any ideas would be helpful.

Thanks.. Craig.

I have the same problem after installing beta 3. You can't even preview the standard app template...

Same problem here. Unable to build standard template in the preview canvas :

`ld: Undefined symbols: unsafeMutableAddressor of self #1 : Crash.Item in Crash.Item.timestamp.init : Foundation.Date, referenced from: Crash.Item.timestamp.init : Foundation.Date in Item.o clang: error: linker command failed with exit code 1 (use -v to see invocation)

Xcode 15 beta 4 Release Notes :

Previewing view code in a SwiftData app results in a linker failure for the canvas despite that code compiling successfully for device and simulator. (111657477) Workaround: Run your app in the simulator to test your UI instead of using Previews.
