Cannot read property appVersion of undefined - iOS

It works perfect in Android version, but in iOS version, I’m receiving this error.

I tried to use version 0.3.0 (Currently using 0.2.0) but I got some errors trying to install via yarn, it throws an error about access in some git files.

I already try react-native link but nothing happens.

Any clue?

I installed version 0.3.3 and got this error. Works fine on Android.

console.log(VersionNumber.appVersion);
console.log(VersionNumber.buildVersion);
console.log(VersionNumber.bundleIdentifier);

all above returns undefined on iOS, but correct values on Android. Do I have to manually link the library or just go with the pod file installation? I have only tried this in the emulator and not on a real device.

I had the same. Fixed now: Did you make sure

1. you used --save so it’s in your package.json
2. when you run react-native link you see in the output it is linked
3. after you’ve run react native link made sure you build the app again (i.e. react-native run-ios) instead of just (hot)reloading? -> and to be sure clean the project in xcode before building again
