Clear the cache of pod with

rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
rm -rf ~/Library/Developer/Xcode/DerivedData/*
pod deintegrate
pod setup

Change flipper version in pod file:

use_flipper!({ 'Flipper-Folly' => '2.5' })

And delete the project's Pods directory. The location of it is project directory > ios > Pods. Then in the project directory > ios location, install pod with pod install And

react-native run-ios

in project directory.

I had this error after upgrading to React Native 0.68.x AppDelegate.m changed to AppDelegate.mm

  1. You have to do this: https://github.com/software-mansion/react-native-reanimated/issues/841#issuecomment-636297029 open the project in XCode, then navigate to Build Phases, in Compile Sources remove the AppDelegate.m file and add AppDelegate.mm instead.

  2. If it is not already renamed: Open XCode, rename AppDelegate.m to AppDelegate.mm in the Project Navigator

This is a bug introduced in Xcode 7.2 (and still not fixed as of 7.2.1), see https://openradar.appspot.com/23857648 It seems that xcodebuild is not setting correctly the ARCH and PLATFORM_NAME variables when invoked with -sdk iphonesimulator.

There are two known workarounds at the moment, both involve passing extra flags to xcodebuild:

1) Pass the -destination flag, eg:

xcodebuild [...] -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6'

2) Override the PLATFORM variable, eg:

xcodebuild [...] -sdk iphonesimulator PLATFORM_NAME=iphonesimulator
