'Flutter won't compile a release build of my app?

After working on this app I tried to build my app to iOS using the flutter run --release command. But whenever I do I get this error *Could not build the precompiled application for the device.*

I've tried flutter clean then flutter upgrade. I've switched flutter branches. I'm so lost on this one!

Here's the terminal output:

Thanks for taking a look!

I finally found a solution!

The problem ended up being that CocoaPod wasn't installed correctly.

After digging for what felt like a lifetime! I installing HomeBrew again, then reinstalled cocoapod using brew install cocoapods command. After that I ran flutter clean and followed that with flutter run and it signed the app and launched it on my iPhone!

Thanks for ideas and helping me figure this out!
