Xcode 10.2.1 Command PhaseScriptExecution failed with a nonzero exit code

After trying all the solutions, I was missing is to enable this option in:

Targets -> Build Phases -> Embedded pods frameworks

In newer versions it may be listed as:

Targets -> Build Phases -> Bundle React Native code and images

• Run script only when installing

Go to

1. Keychain Access -> Right-click on login -> Lock & unlock again

2. Xcode -> Clean Xcode project ->Make build again
