Mapbox Core Navigation and Swift 5 compile errors

[z-mp]

Would you pls add support for Swift5/Xcode 10.2?

In related news, the 0.30.0 release doesn't build with Xcode 10.2 (using Carthage).

We’re working on Xcode 10.2 compatibility (but not a Swift 5 migration yet) in #2074 and mapbox/mapbox-directions-swift#363.

Just wanted to add that one of the issues with Xcode 10.2 compatibility and Carthage was caused by merging Swift headers. There's a fix in Carthage on master but not yet released. (brew unlink carthage && brew install carthage --HEAD installs latest Carthage from master)
Carthage v0.33.0 is required
