Ah! Sorry for that.

@AyonAB do you have time to fix it in a Pull Request?

[AyonAB]

Sure, can do that.

[Cheesebaron]

@AyonAB that would be much appreciated.

I guess we should check either if the selector is available or iOS version is met.

[AyonAB]

@Cheesebaron done. Review the PR when you can.

@AyonAB thanks! Will have a look!

I've made a new release 1.3.1 with your fix. Thanks again!
