Deprecation warnings for iOS12

[SlavcoPetkovski]

Hi.

I have updated the library to 4.0.0 and still see the warnings for deprecation for iOS12.

Can you fix them?

I'm thinking about how best to approach this. I can bump the minimum iOS version to iOS 12 and remove the deprecated api. But I wonder if that's going to alienate any users that support older versions.

I should have done this as part of bumping the major version to 4.0 but I was just trying to get all the updates out and wasn't thinking through it all.
