It just started this after updating Xcode to iOS 11.2.

This is a dupe of #46. It's an annoying issue that keeps happening to me and the solution is always some amount of cleaning, removing, reinstalling, etc. but it always takes me a few tries to get things straightened out. Really wish there were a real fix :-(

[luco]

I agree with @tonygentilcore. Cleaning doesn't solve the problem. It keeps coming back.
Also, none of proposed fixes on #46 fixes the issue.

[tomauty]

Try Shift+<, Build phase, uncheck Parallelize Build

[eballeste]

this started to happen to me once i upgraded my os to sierra and xcode from 8.3 to 9.2.

no amount of cleaning, rebuilding, deleting the derived data folders, unlinking / linking, upgrading rn-fast-image from 1.0.0 to 2.0.1, having parallelized builds unchecked etc etc. will get my build to run completely with react-native run-ios, always fails, works when built from xcode...

It's unfortunate that there are so many sources of this sort of issue. I commented on it in the duplicate issue: https://github.com/DylanVann/react-native-fast-image/issues/46#issuecomment-373993701
