Describe the problem

When I followed the instructions to set up a test project, I got an error

Flutter failed to write to a file at "xxx/Build/Products/Debug-iphonesimulator/.last_build_id".

To fix this, ENABLE_USER_SCRIPT_SANDBOXING in the Xcode project's build settings needs to be set to NO

Expected fix

Add instructions to set ENABLE_USER_SCRIPT_SANDBOXING to NO
