I think I have worked it out.
I had a folder on the Mac desktop which contains the B4i local builder files, since this is where I was running the files.
I had to move the files to a directory where the iCloud doesn't backup. From the Google search I did today many others had similar issue and they had to move the project to a different folder that the iCloud doesn't backup.
In my case I moved it from the desktop to /Applications/macserver and then run the files from that location and it now seems to let me build the project successfully.
Is there an existing issue for this? I have searched the existing issues I have read the guide to filing a bug Steps to reproduce flutter run --verbose (iOS device) This issue happens on a project ...
