Even though Objective-C is no longer the primary language of iOS, that doesn’t mean that there aren’t millions of existing Objective-C apps out that still need support. Objective-C is also perfectly interoperable with Swift, so you can have your legacy components communicating with modern Swift modules without difficulty.  If you have an app that has been built prior to 2014 and need maintenance or you want to convert your codebase to Swift or Flutter, look no further!
