Summary: Fixes https://github.com/facebook/react-native/issues/29984 Right now, running a React Native application with Xcode 12 in Release mode on an iPhone Simulator will fail with something like below: > [some file path], building for iOS Simulator, but linking in object file built for iOS, file '[some file path]' for architecture arm64 The best explanation of this issue has been provided by alloy in https://github.com/facebook/react-native/issues/29984: > This issue has started coming up with Xcode 12 and support for the new ARM based Macs, as `arm64` now no longer can be assumed to _only_ be for iOS devices. This means Xcode 12 will now also build for `arm64` simulator SDKs and it has become ambiguous if an arch slice in a prebuilt binary is meant for a simulator or device. > > In any case, for now this means that you can configure your Xcode project to exclude `arm64` when building for any iOS simulator SDK. This PR implements aforementioned workaround. ## Changelog [FIX] [IOS] - Fix running React Native project with Xcode 12 in Release on iPhone Simulator Pull Request resolved: https://github.com/facebook/react-native/pull/30543 Test Plan: Switch your scheme to Release and run the app on simulator. Will complete w/o issues. Reviewed By: appden Differential Revision: D25537295 Pulled By: TheSavior fbshipit-source-id: 2dc05cb80e59f1d95d2a84ab55ed6a5b5446411c
