This error message is typically encountered in Xcode or the iOS simulator when class information for an Objective-C class cannot be loaded. There are several reasons why this might occur, including outdated versions of Xcode or the simulator, missing or corrupt files, or issues with your project configuration.
Here are some steps you can take to try and resolve the issue:
1.Make sure you have the latest version of Xcode installed. You can check for updates in the App Store or by going to the Xcode menu and selecting "Check for Updates".
2.Clean your project and rebuild it. In Xcode, go to the Product menu and select "Clean", then rebuild your project by going to the Product menu and selecting "Build".
3.Delete the DerivedData folder for your project. This folder contains build artifacts and can sometimes cause issues. You can find the location of the DerivedData folder by going to Xcode preferences, selecting "Locations", and looking under the "Derived Data" section. Once you've located the folder, delete it and try rebuilding your project.
4.Check your project configuration. Verify that your project is configured correctly and that all required files are present. You can also try deleting and re-adding any problematic files or frameworks.
5.Restart Xcode or the iOS simulator. Sometimes simply restarting Xcode or the simulator can help resolve issues with loading class information.
If these steps do not resolve the issue, you may need to seek further assistance or debug the problem in greater depth
