On fresh react-native app, after npm install --save react-native-vector-icons and react-native link react-native-vector-icons, when I try to react-native run-ios, build fails with following:

I am on:

@cmcewen any thoughts?
apparently react-native link adds all targets to the ios target even if they are meant for tvOS
to get your app running remove the -tvOS.a file from link binary with libraries so it looks like this:

have filed an issue here: https://github.com/facebook/react-native/issues/13783
Gonna try it! Will let you know.
It works fine using the steps you mentioned! Thanks.
Thanks @cmcewen that worked for me also.
FYI, for those who are using react-native 0.49.3 then you may also run into https://github.com/react-native-community/react-native-svg/issues/460
