Description

After updating to Xcode 12 I get this error:

The linked library 'libPods-*****.a' is missing one or more architectures required by this target: arm64.

Anyone knows how can solve it?

For everyone running into

building for iOS Simulator, but linking in object file built for iOS for architecture arm64

Please upgrade to the latest CocoaPods (at least 1.10.0).

If doesn’t work:

Note: If you are using Hermes, this will not work. Go to the next workaround.

Please go to Build Settings -> Excluded Architectures -> Debug (or the schema you are using to run on an iOS Simulator) and add arm64 there. See https://stackoverflow.com/questions/63607158/xcode-12-building-for-ios-simulator-but-linking-in-object-file-built-for-ios for more.

If doesn’t work:

Do it for both your project and Pods. If your project is named RNTestProject (react-native init RNTestProject), you will have to do it for RNTestProject and Pods. Remember to do it in both places, otherwise, the error will keep happening.

More information on this workaround is available in this StackOverflow issue: https://stackoverflow.com/a/64139830

Please keep in mind that this is workaround and not an official answer to the problem. We will investigate this and publish a recommendation once we have analysed all the pros and cons of each alternative solutions.
