Class _PointQueue is implemented in both when I click on textfield... How can I resolve this issue?

Question

I'm using xcode 13 and making a demo on coredata.

objc[6188]: Class _PathPoint is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/UIKitCore.framework/UIKitCore (0x114a8fa78) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/TextInputUI.framework/TextInputUI (0x12cd4a8b0). One of the two will be used. Which one is undefined.

Apple developer Quinn “The Eskimo!” @ Developer Technical Support @ Apple answered this question here:

This is not an error per se. Rather, it’s the Objective-C runtime telling you that:

• Two frameworks within your process implement the same class (well, in this case classes, namely _PathPoint and _PointQueue).
• The runtime will use one of them, choosing it in an unspecified way.

This can be bad but in this case it’s not. Both of the implementations are coming from the system (well, the simulated system) and thus you’d expect them to be in sync and thus it doesn’t matter which one the runtime uses.

So, in this specific case, these log messages are just log noise.

This error usually happens when you add a gesture recognizer inside a view that also has a gesture recognizer of its own. In your case, you may have added the textField as a subview of a view that has some sort of gesture recognizer, or scroll. So when you tap on that textField, it does not know which gesture to trigger. So, look into your implemetation and figure out if the textView is inside another view that has a geture.

In my case, I created a view, which had a gesture recognizer, and this view had a UITextView() as a subview. So when the parent view was tapped and the gestured was used, I would get this error. I solved it by disabling user interaction on my textView.

textView.isUserInteractionEnabled = false
