Answer 1

It might be related to a singing issue.
I was facing the same issue where the app was forking fine when I did
flutter run // Working
But when I tried creating the ipa for distribution, it used to give me an archive failed error.
flutter build ipa // Error
I tried to do flutter clean, xcode clean and all the other different things but nothing worked.
So, I tried with a sample app, and then ran flutter build ipa which asked me to setup my certificate on that project which I did and it worked fine.
When, I came back to my original project, and it also started working. So, it was definitely some certificate issue which was leading to all these problems. Using a sample project, helped resolve it.
