Fix header file warnings that appear for consumers of this client on Xcode 10.2 #168

Closed rbaumbach closed 5 years ago

rbaumbach commented 5 years ago

When consuming this code/pod/etc. in a project that is using Xcode 10.2, warnings are given due to missing nullability identifiers. I went ahead and resolved these as best as I could based some assumptions.

This will resolve the issue: https://github.com/launchdarkly/ios-client/issues/167

Please review and let me know if I need to change any of the nullable identifiers to non-null and vice versa.
