After upgrade Xcode 13，run playground occur a error。

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.

Messages are pretty clear but I do not know why they happen or show in debug area. Adding following lines at the first or second line of my playground project page just works for me. I hope it helps you too.

import PlaygroundSupport;
defer{ PlaygroundPage.current.finishExecution() } 

My guess about the cause of this situation is that compiler keeps doing things after your code finish executing, such as it walks over libraries, tries to optimize things in the background, etc... I think in practice we never use conflicting libraries in any real projects at the same time, so that it only occurs at playground.

Regards,

It shows the error "No such module PlaygroundSupport" in my code I am trying to navigate to new view controller so I use {let goToNewVC = storyboard?..instantiateViewController(withIdentifier: "nameof the identifier" ) as! identifier class name navigationController?.pushViewController(goToNewVC, animated: false)} but this error shows one of the two will be used .
