Flutter gets stuck on "Running Xcode build... " when building for iOS

Question

I have an existing Flutter project which has been working fine for two years. But now all of a sudden, when I try to build or run it on iOS, it always gets stuck on Running Xcode build... .

flutter build ios --debug
Running "flutter pub get" in MyApp...                           0.6s
Building org.example.myapp for device (ios)...
Automatically signing iOS for device deployment using specified development team in Xcode project: 36U5A9XK2Z
Running pod install...                                              1.6s
Running Xcode build...                                                  
(This is taking an unexpectedly long time.)       ?

Before this would only take 1-2 minutes, and now I've tried waiting up to 2 hours, so obviously something is very wrong. Other existing apps build just fine.

I have tried "the usual suspects":

• flutter clean.
• Delete ~/Library/Developer/XCode/DerivedData.
• Restart the computer.
• Delete podfile.lockand run pod install again.
• Removed some "difficult" plugins (i.e. everything Firebase-related and all Swift-based plugins).

Nothing seems to help. Same thing happens if I try to run the app from within XCode or IntelliJ. Version info below.
