Provide nullability annotations for Swift callers

[Wenzhi]

Hi Keith,

Thank you for the suggestion! It's something we want to do too, and is not hard to implement. We should be able to do it soon, and will let you know when we release it.

+1. I asked this if our appboy contact yesterday.

Hi @keith and @justin,

The new iOS SDK (version 2.18.0) now has nullability annotations, Please check it out and let us know if you see any issues or have any questions.

Thanks,
Wenzhi

Thank you! I'll give it a whirl and provide some feedback in a separate ticket if i run into anything.

Looks like this added some new warnings for some missing identifiers:

Hi @keith,

I just release version 2.18.1 on both the repo and Cocoapods. It should fix the warnings. Do you mind checking that version and telling me if it fixes the warnings?

Thanks,

[keith]

That fixed it, thanks!
