I get this error all the time! Usually when trying to build my iOS app.

Things that normally fix it are:

cd ~/ios/

rm -rf Pods

rm Podfile.lock

cd .. to (to get back to main flutter dir) flutter clean

If that doesn't work you can also try these afterwards

cd /ios/

pod deintegrate

pod install

If issues persist after those and this happens when trying to build your iOS app sometimes its a good idea to back up your iOS folder delete it and then run flutter create this will generate a new iOS folder so you have a fresh runner and can make a fresh pod file.

If none of my solutions worked for you can also check out this SO thread because this issue pops up a lot.

What version of flutter are you using?
Flutter 2.0.4 version
@ChetanKhanna were you able to fix this issue? I am facing the same issue and I am using Flutter 2.0.4 as well.
@JunaidRehmat what I did was remove the packages that were causing these errors.
@ChetanKhanna In my case it was Firebase Crashlytics and other required packages, so I updated them one by one and that fixed the issue.

Not sure why but I uninstalled cocopods and re installed using brew and did the following:

sudo gem uninstall cocoapods brew uninstall cocoapods sudo gem install cocoapods

then clear cache data

sudo rm -rf ~/Library/Developer/Xcode/DerivedData/; sudo rm -rf ~/Library/Caches/CocoaPods/ rm ios/Podfile.lock rm -rf ios/.symlinks rm -rf ios/Pods flutter clean flutter pub get cd ios pod deintegrate && pod install --repo-update
