After upgrading to XCode 10.3 my iOS local builds started to fail on CompileAssetCatalog. From what I searched it happens for Native iOS project and React Native ones as well.

Here’s how you fix it:

  1. On XCode, clean the build by going to Product › Clean Build or by hitting ⌘⇧K and ⌥⌘⇧K
  2. Go to ~/Library/Developer/Xcode/ and delete the following directories:

    • iOS Device Support
    • DeviredData
    • Archives
  3. Restart your macOS
  4. Run the build again

Hope that helps!
