Thanks for your reply! I was able to confirm that the method you suggested worked correctly. I also discovered that it works correctly without AccessoryWidgetBackground(). Button(intent: intent) { ZStack { if showsWidgetContainerBackground { Color.black } else { Color.primary.opacity(0.15) //AccessoryWidgetBackground() } ... } } .buttonStyle(.plain) .widgetURL(URL(string: "widget://" + intent.id)) This problem seems to occur when using both AccessoryWidgetBackground() and .buttonStyle(.plain). Maybe this is a bug? I'll add this information to the feedback(FB15151000). Thank you very much for your help!

Thanks for your reply! I tried using Button instead of Button(intent:...) and the widget URL wasn't passed correctly. It always returns the URL of the first button.

In my case, the problem was caused by an external display connected via USB. When I connected the iPhone 16 Pro with a USB cable, it appeared in Finder but not in XCode. The external display was made by LG and I was using it in clamshell mode. Once I disconnected the USB connection to the external display, XCode was able to recognize the iPhone.
