C++ maybe, but not Objective-C.

I've written plenty of high quality apps in Objective-C. They virtually never crash. And I never have to update my code because the language changed.

Stick with Objective-C and abandon Swift.

I spent 20 years in the Objective C world, and wrote my iOS apps in Objective C for nearly 5 years. If your apps virtually never crash you are an outlier, and you are working far too hard at it.

Swift's strong typing and optionals make it easy, fast and natural to write safe code, stuff I used to use masses of libraries to help me do in Objective C.
