Got the same issue, gonna try to upgrade since there's new releases. I´ll let you know if I find anything!

What I have found is that if you clean up enough things (Pods dir, Podfile.lock, node_modules dir), and then you run pod install manually from the ios dir, it will start working. It needs to regenerate the workspace. This is not specific to this control. I have seen this several times. It seems to be pervasive with react native on iOS when updating dependencies.

This package depends on @react-native-picker/picker. You must install it to avoid this error.

I'm also hitting this issue. Nearly all solutions I've found mention the need for installing @react-native-picker/picker but I have done that and still get the error.

I was hitting the same issue even when i did a reload of the app after all of the install instructions. It began to work without any further changes after killing the expo process and re-running npx expo run:ios
