How to troubleshoot simulator errors?

There are a few common issues that can occur when using the simulator, and several steps you can take to troubleshoot them:

• If the simulator is not launching or displays an error message, try quitting and reopening the simulator and IDE.
• Ensure you have installed the latest Xcode version.
• If the app crashes, check the IDE console output for error messages. These can often give clues as to what is causing the crash.
• Try cleaning the build (in Xcode, select "Product > Clean Build Folder" from the menu bar).
