Is it valid to program in objective c?

Question

Objective-C

Now I'm going to order the application. The programmer says that he knows swift but obj c almost forgot.
He also suggested that you can develop an application very quickly if you use frameworks such as www.baasbox.com/getting-started-ios but here the implementation language is obj c. Swift is available only on the
kumulos framework But it costs $50 per month, this is not an option))
Here is a list of all frameworks
waracle.net/how-to-choose-the-right-backend-as-as...
closes in a year.
So the question itself is: Is it valid to program in objective c?

Answer 1

The average opinion on this matter is this:
Swift on OSX is a newcomer, budding.
Objective C was originally on OSX and won't go anywhere for many years until Swift learns to do everything just as well.
