Cleaning Derived Date

Clear the following directory: home/Library/Developer/Xcode/DerivedData

Simulator Cache

One time I changed a model using SwiftData and my preview kept crashing; I'm guessing because the cached was jacked up and wouldn't stop crashing. So, I opened the simulator, Device | Erase All Content and Settings... which fixed my preview. Make sure you clear the content on the same simulator you're using for your preview.

Build Error on Xcode 13

The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

Solution

Project | Info | Custom iOS Target Properties
Add "Privacy - Camera Usage Description" with value of "${PRODUCT_NAME} Camera Usage"
