Swift or Objective-c? is swift future or not realy?
Looking on how Apple adversites Swift it is safe to use Swift for Apple products. But sucess of Swift crossplatforming is unclearly. I would be more concern about using Obj-c. It has some problem with it's legacy and can't evolve as fast as Swift, C# or Python does. But all above that a good developer should easily switch to new language without any problems. So you shouldn't choose only one language but look at any language as a tool for certain proposes. Some languages are better for game dev. other for business app.
None of the two languages are better than the other. They were created to be used together just like many other programming languages since each has its own strengths and weaknesses depending on their use
