SwiftUI Preview crashes with List ForEach subviews on macOS
When using a custom subview inside List ForEach for macOS, Xcode Preview crashes. Add AnyView(EmptyView()) as a workaround.

I ran into a SwiftUI Preview crash when building a macOS app. The preview works fine for iOS, but crashes for macOS targets.
The crashing code
This minimal example reproduces the crash:
struct ContentView: View {
var body: some View {
List {
ForEach(0..<3, id: \.self) { _ in
SubView() // Crashes preview
}
}
}
}
struct SubView: View {
var body: some View {
Text("Hello, World!")
}
}The preview crashes with PREVIEW UPDATE ERROR: GroupRecordingError. The crash only happens when using a custom subview inside List { ForEach }. Inline views like Text("Hello") work fine. Using the “Use Legacy Previews Execution” option did not help.
The workaround
Adding AnyView(EmptyView()) prevents the crash:
struct ContentView: View {
var body: some View {
List {
ForEach(0..<3, id: \.self) { _ in
#if DEBUG
AnyView(EmptyView())
#endif
SubView() // Works
}
}
}
}Environment
