im tring to build my iOS App but it fails with next error:

No such module "_concurrency"

I undestand that the compiler that xcode is running has this module deprecated.

I dont know how to solve it. Please, I need help.

Config: "react-native": "0.64.3", "expo": "^43.0.3", "react-native-fbsdk-next": "^9.0.0", "expo-modules-core": "~0.4.10"

xcode version: "12.5.1" iOS Deployment Target 12.0 swift: 5.4.2

Your version of Xcode is too old (12.5.1). You'll need to upgrade to 13.
