This simple project just makes the Swift compiler crash in init(comparator: KeyPathComparator<RemoteComputer>):
import SwiftUI
struct ContentView: View {
var body: some View {
VStack {
Image(systemName: "globe")
.imageScale(.large)

Text("Hello, world!")
}
.padding()
}

This code works fine in previous betas or Xcode 15.
