Swift support for LTSupportAutomotive 1.1

[mickeyl]

This issue keeps track about the forthcoming Swift support for LTSupportAutomotive. I'm planning to:

• Relayout the source files to make the Swift Package Manager happy (while not breaking the .xcodeproj)
• Check/Adjust nullability annotations
• Check/Adjust lightweight generic annotations
• Check/Adjust enums
• Check whether we can make the package work on Linux
• Register with the https://swiftpackageindex.com and the https://swiftpackageregistry.com

After that we can tag and release 1.1.
NB: I don't plan rewriting this library in Swift any time soon. However I want to make the call sites as swifty as possible.

I would love it if you could do this, I couldn't find any examples of Swift calling LTSSupportAutomotive...but would definitely use it if I could figure out how to do it.

The first bits of that have landed in the SPM branch. I have feedback from people using this from Swift. I should perhaps rebase it on master and make it the default branch.

It would be great to have a simple sample of how to use the library from Swift @mickeyl - I looked at the spm branch but didn’t see this. Ie just a ‘to be done’ note.

As far as I’ve been able to find (with a lot of searching) there is no library for ble access to obd2 written in swift available. I would wrap your lib myself if I could but my obj-c skills are non-existent and am working on learning swift as I go on this project.
