The sample project looks weird...

I ran the sample project on iOS 10.3, iPhone SE simulator, Xcode 8.3.2 and it looks like this:

I don't think the clock is supposed to be oval shaped. The black bars at the bottom and top are not supposed to be there, right?

Right, it's completely screwed.

Would you fix it?

Can't guarantee. I don't work with this framework now and don't have much free time these days.

Have just checked and can confirm the issue on iPhone SE / iOS 10.3, 10.0 and iPhone 7 / iOS 10.3 simulators in Xcode 8.3.2.
