I am working on a React Native Project based on a bare workflow, and my project is not working on Xcode. I use expo modules but when i want to setup my ios project by the command "expo prebuild" i get the following error:

⚠️ Something went wrong running pod install in the ios directory. Command pod repo update failed. └─ Cause: Couldn't install: EXFont » UMCore. Ensure the CocoaPod "UMCore" is installed in your project, then run npx pod-install to try again.

It seems Cocoapods did not install this file.. but i have no idea how to do it.

And When i launch the command "pod install" i get : "[!] Unable to find a specification for UMCore depended upon by EXFont"

I followed this guide from Expo : https://github.com/expo/fyi/blob/main/expo-modules-migration.md It works fine on my Android Project.

I got the latest version of Expo and CocoaPods and my Xcode version is 13.0.

Any idea ? I did not found a lot of topics on this subject, and none solve this error...

I had similar errors after updating the expo. In my case it was:

  • [!] Unable to find a specification for UMCore depended upon by EXSecureStore
  • [!] Unable to find a specification for UMCore depended upon by EXLinearGradient

Solution

expo install expo-secure-store
expo install expo-linear-gradient
cd ios
pod install --repo-update --clean-install

To solve your issue, I think you need to do:

expo install expo-font
cd ios
pod install # or `pod install --repo-update --clean-install`
