"-[_NSXPCDistantObject ___nsx_pingHost:]: unrecognized selector sent to instance 0x600000408140" error while working with photo editing extension

Started working on a photo editing extension in Xcode. no matter what I do whenever I select my extension to edit a photo the app crashes with the following error.

After finding the solution for hours only thing I got was to uninstall and restart the app, but that too didn’t work.

The following is the screenshot of the error.

This is the console output after the app stops working:

For more understanding, I have attached a Google Drive video link.

Which Xcode version ? Could you post the crashlog itself ? Are you using any third party framework ?

Did you see those old threads ? It says that problem should have been resolved, but apparently not totally:

https://stackoverflow.com/questions/33703799/ios-9-crash-on-nsxpcdistantobject-methodsignatureforselector

and eskimo's in depth explanation:

https://developer.apple.com/forums/thread/45651#140745

The Xcode Version is 12.5.1. Also, the crash log is empty. No, I have used no third-party framework.

Accepted Answer
