Answer 1

Xcode 8.2 still occur same error. Three lines bellow fixed it for me :) Downgrade react(16.0.0-alpha.12 -> 16.0.0-alpha.6) & react-native(0.45.0 -> 0.44.0)
rm -rf node_modules/react
npm i [email protected] -S
npm i [email protected] -S
Then run react-native run-ios

Answer 2

Your build could be failing because of the current node js version installed, or due to your pod files or a number of other reasons.

This error may also be when cloning a react native repository from github.

This solution may work as I was able to recreate this issue(refer to the screen shots):

Solution one:

firstly:

If you have the latest version of node js installed you may have some compatibility issues with some of the dependencies, install the recommended version of Nodejs instead.

after installation, reinstall your dependencies and update your pod files:

npm install
cd ios
pod install 

or

pod update

solution two:

this can happen if you haven't installed react native previously on your system and are trying to run a clone react native repository from github.

brew install watchman
sudo gem install cocoapods

then in the rn project clone

 cd ios 
 pod install

Problem:

This is what the error message looks like:

legacy compatibility issues:

Build failed

Solution:

After following the above steps this issue was resolved instantly:

If it's your first project, you may have the same problem than me: do NOT use space in your project path! 🎉 😄
