Why Does SwiftUI TextField Trigger a 'FAULT: TUICursorUIViewService' Error in Xcode?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm developing a SwiftUI app that contains a TextField using the code below:
SWIFTimport SwiftUI struct ContentView: View { @State private var text: String = "" var body: some View { VStack { TextField("Enter text...", text: $text) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() Text("You entered: \(text)") .padding() } } }
However, upon running the app, the Xcode console displays the following error:
FAULT: <NSRemoteView: 0x7fae1671cf80
com.apple.TextInputUI.xpc.CursorUIViewService TUICursorUIViewService>
determined it was necessary to configure <TUINSWindow: 0x7fae16707110>
to support remote view vibrancy
I also attempted to wrap an NSTextField from Cocoa into a SwiftUI view using NSViewRepresentable, but encountered the same error.
Is this error a cause for concern, what triggers it, and how can it be resolved?

This error is actually benign. The message about configuring the window for “remote view vibrancy” is logged by the underlying text input services and doesn’t indicate that your SwiftUI app is failing or misbehaving. It appears when the system is setting up features used by editable text views, especially when using a bridged Cocoa text field (or SwiftUI’s native TextField which leverages similar mechanisms).
In short:
-
Cause: The error results from the system’s internal handling of text input views that support vibrancy (a visual effect) in macOS. When a text field is created, the system checks if the window needs a configuration to support remote view vibrancy—but this code path isn’t critical for most apps.
-
Impact: There’s no negative effect on your app’s behavior. You can safely ignore the logged error.
-
Resolution: No action is required. If the warning bothers you, you might check for any system updates or changes in SwiftUI’s text field styling, but current consensus in the community is that this message is noncritical.
So, you do not need to be concerned or modify your code. Your SwiftUI TextField will work as expected despite the console message.
