Steps to Reproduce

1. Create new expo project with expo init

2. Eject with expo eject, choose ExpoKit

3. Follow the docs to add the Payments Module on iOS

Expected Behavior

pod install should run without problem.

Actual Behavior

pod install failed with error message: Unable to find a specification for ‘UMCore’ depended upon by ‘EXPaymentsStripe’

Temporary Solution

I figured out expo sdk32 doesn’t work with the latest version of expo-payments-stripe. Remove installed expo-payments-stripe. Install expo-payments-stripe@3.0.0 and it should work just fine.

So I did end up getting this to work. What I did is I want into node_modules/expo_face_detetector/ios (I’m on mobile by the way I think that’s right) and I found everything that was UM like UMcore and UM_register_module() and changed them to EX so EXcore and EX_register_module().

This problem was occurring due to incompatible versions of Stripe/FaceDetector package and the unimodules core.
