It's a bug. I just saw this: https://mastodon.social/@denisdepalatis/110561280521551715

I'm seeing this when I attempt to use a ClosedRange as the type of a model property.

Yep, I'm still seeing the issue with ClosedRanges on beta 5.

Thanks Quinn! I guess it is just my head playing tricks on me. Damn... and the sandbox means that there is no way to do this from an App Store app?

I've verified this on a second machine. Easy to see the issue by adding an image to your Assets and this piece of code: Button("Test", image: .myImage, action: {}) This will build but crash on launch.

Yep, that works. Here is the workaround: @MainActor func Button(_ str: String, image: ImageResource, action: @escaping () -> ()) -> some View { Button(action: action) { Label(str, image: image) } }
