When using SwiftUI's TextEditor, the application crashes immediately on launch.
This occurs even in a brand new project with the simplest usage.
If I remove the TextEditor, the application runs normally.
Environment:
OS: macOS 15.6.1
Xcode: 16.4
SDK: macOS 14 (and also tried with macOS 15 SDK)
Steps to Reproduce:
Create a new SwiftUI macOS App project.
Replace ContentView with the following code:
import SwiftUI
struct ContentView: View {
@State private var text = "114514"
var body: some View {
TextEditor(text: $text)
}
}
Run the app.
Expected Result:
The app should display a working TextEditor.
Actual Result:
The app immediately crashes, and the debugger shows a Metal assertion error.
If I remove the TextEditor, the app works fine.

Additional Notes:
This issue did not occur on macOS 14 / Xcode 15.4.
It reproduces even in an empty project.
Possibly related to SwiftUI/Metal integration on macOS 15.6.1.
