How to fix Flutter Xcode error “Unable to boot the Simulator”

by staff

Flutter is an open-source framework by Google for building beautiful, natively compiled, multi-platform applications from a single codebase.

Xcode enables you to develop, test, and distribute apps for all Apple platforms.

We have good news: There is no need to uninstall Xcode for this issue.

On MacOS 13 and above

  1. Go to System Settings -> General -> Storage -> Developer.
  2. Delete “Developer Caches”.

If you use MacOS 12 or below version.

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

I hope it will help you 🙂
