I'm starting to work on a SDK from scratch. I'm not really sure if I should write it in Swift or Objective-C. I feel Swift is better than Objective-C in many aspects, but my major question is - Will swift dynamic libraries support older version of Swift. Say I write my dynamic library in Swift 3.0, will I be able to use that dynamic library in a project using Swift 2.2? I found this in an article I was reading
Dynamic libraries are executable chunks of code that can be linked to an application. This feature allows current Swift applications to link against newer versions of the Swift language as it evolves over time.
Does this mean that I will be able to run a dynamic library built in Swift 3.0 in a project using Swift 2.2? I also found this in Apple documentation
First, Swift 2.3 and Swift 3 are not binary compatible so your app's entire code base needs to pick one version of Swift.
I find this quite contradicting to the first statement. I know importing Objective-C libraries in Swift is pretty straightforward using a bridging header, does the same go for the opposite scenario? Will there be any issues or hurdles I'll step onto when trying to make the Swift library work with Objective-C project. I couldn't find any answers or articles which address backward compatibility. Any help is much appreciated. Thanks!
TLDR: Are dynamic libraries built with Swift 3(or greater) compatible in projects using older versions of Swift or projects in Objective-C
