Window NSWindow 0x137632e40 ordered front from a non-active application and may order beneath the active application's windows

I'm seeing something similar. A blank document project generates a similar error code.

Same here

Me too

I'm seeing this in a lot of my apps. Running macOS 13.4, Xcode 14.3. App code unchanged, so this must be new log noise which started with macOS 13.3 or .4...

The warning error log is actually reflecting the actual app behavior. No wonder why sometimes my app window is not opened in frontmost position.

This is not a meaningless issue. This will cause unexpected behavior like error alert doesn't show in SwiftUI. If you encounter the same like me. You can get the window and make it key and front to fix this issue.

I used https://github.com/happycodelucky/SwiftUIWindowBinder to get the NSWindow. And used below func to make it key and front.

var body: some View {
    WindowBinder(window: $window) {
        // content view
    }
    .onAppear {
        makeKeyAndFront()
    }
}

private func makeKeyAndFront() {
    if let window {
        window.makeKeyAndOrderFront(nil)
    } else {
        DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(100)) {
            makeKeyAndFront()
        }
    }
}

I started seeing same warnings but they weren't there before. Not sure if some behaviour on macOS changed or is just noise, but to on the safe side I changed my implementation to open the first window on my app.

The key is to use orderFrontRegardless() instead of makeKeyAndOrderFront(nil)

Example

func applicationDidFinishLaunching(_: Notification) {
   let window = Window()
    window.makeKey()
    window.orderFrontRegardless()
}
