Thanks for reporting this, @muaviya . Could you run pod update and see if that fixes it? Could you also confirm which version of CocoaPods you're using?

pod update doesn't help

pod version 1.8.4

[romoore]

Unfortunately, MDC-iOS currently supports CocoaPods 1.6.1. Could you try with 1.6.1 and report back on the results?

excuse me, how I can install cocoapods 1.6.1?

[romoore]

How you switch to 1.6.1 depends on how you installed CocoaPods. I installed using Ruby Gems, so I specified the version I wanted explicitly.

sudo gem install cocoapods -v 1.6.1

Do you plan to upgrade to the latest version cocoaPods ?

[romoore]

@jverkoey @randallli Do we have plans to support newer versions of CocoaPods this year or early next?

This bug is now being tracked by https://github.com/material-components/material-components-ios/issues/8997.

Also, for what it's worth, I just tried creating a new project using Cocoapods 1.8.4 and had no problems running pod install or compiling the app.

@muaviya, did you try clearing derived data using option+command+shift+k?

So far I've tried on both the MDC Catalog and a new sample project after clearing derived data, clearing the cocoapods cache (pod cache clean --all), and doing rn -rf ~/.cocoapods and everything has worked.
