Flutter: XCode error "Unable to boot the Simulator"

Iam running the latest OSX/Flutter/XCode Versions using flutter, android studio and firebase and 1 hour ago everthing works perfectly.

Then i rebooted my macbook and when i try to launch an ios simulator i get this error "Unable to boot the simulator".

The following steps shows no solution:

  1. Reinstall the ios simulator
  2. Flutter clean and pub get
  3. Updating comand line tools 13.3.1 (13E500a)
  4. Run invalid cache of android studio

I found the problem also on stackoverflow but all sugestions does not working.

Any ideas?

    After checking some other comments, it seems uninstalling XCode is not necessary.

    The issue is not directly related to Flutter but it is related to the XCode 13.3.1 with the Simulator, specially for iPhone and iPad (tvOS and watchOS should have no issue so far).

    Somehow the existing files during the security update causes the simulator to get corrupted.

    As temporary workaround, you can try the following steps:

    1. Uninstall XCode by moving from Applications folder to the Trash
    2. Empty the Trash
    3. Open the Mac Storage Management and go to the Developer in the sidebar
    4. Delete everything from the Developer Section
    5. Download Xcode 13.1 from Apple Developers and not the stable release from App Store
    6. Extract the downloaded Xcode_13.1.xip file, i actually recommend via terminal by using xip -x Xcode_13.3.1.xip, and take in mind the extraction uses 100GB and it takes up to 2 hours to complete. You are going to have this message at the beggining xip: signing certificate was "Software Update" (validation not attempted), but you can ignore since this is expected.
    7. Finally, move the extracted XCode file to the Applications folder
    8. Run sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
    9. Run sudo xcodebuild -runFirstLaunch

    NO NEED TO UNINSTALL XCODE! Though I know the contributor already has solved the issue, I’m happy if this answer will help someone else.

    1. Go to [About this Mac > Storage > Manage > Developer]
    2. Delete all the content (no worries!)

    For me it was not necessary to delete XCode. I could solve it with this:

    1: Click on "About this Mac" in the top left corner

    2: Click on "Storage"-Tab

    3: Click on "Manage"-Button

    4: Click on "Developer"-Tab

    5: Right click on all the data and "Delete"

    You can just clean your Xcode Caches, and that will do the trick,

    1. About this Mac
    2. Storage
    3. Developer
    4. XCode Caches
