Error/warning on failing build: "Can't merge pod_target_xcconfig for pod targets"

No response

Summary

EAS build that has no issues with npx expo-doctor prints this (non-fatal?) error/warning during builds. Although it doesn't seem fatal, the build is failing later in the process and I can't be sure this is unrelated to the failure.

Managed or bare?

To everyone commenting +1 and the like, it would do you much more good to:

1. Add a thumbs-up (maintainers can organize issues by their number of reaction emojis)
2. Add a meaningful comment with your findings, or otherwise subscribe to notifications on the right-hand-side to avoid cluttering the thread

Hey did you find a solution to this? I'm also facing this issue.

[aimeeaidanu]

Yeah I fixed it by updating expo-cli

[abhishek-pavesoft]

@aimeeaidanu I also resolved it a few minutes ago by changing iOS target version from 13.0 to 13.4.

[Nantris]

@aimeeaidanu to what version? I think expo-cli upgrades can change the iOS target version (though generally only for major releases?)

I was on the latest at the time when I filed this.
