iCloud Entitlement to app?

Question

So, I've registered for Apple's Developer program just yesterday and I've added my details in Xcode.

If you scroll a bit, you will see that it requires to sign in with your developer's account in order to activate iCloud.

That's cool, but I get 2 errors that I can't figure out how to solve (and where to solve it):

I'm new to this and I tried google-ing it (of course), but I couldn't figure out how to solve it.

Edit: You may need to enable iCloud in Member center too

Answer 2

I solved the issue. I can't really tell how, but I've connected my iPhone to Xcode and clicked on "Fix issues" again it worked this time. Not sure why or how...
