I won't put survival rating for it to be very big. I'm sure Apple would keep it for decades to come, but I'm wouldn't bet on it being anywhere near as popular as it is now in the future.
TensorFlow also has a Swift API in development [3]. The people at FastAI seem quite excited about it [4].

Swift is actually a very pleasant language, and apple provides some pretty good documentation although it could be better.
It's going to play out like this: Swift or Objective-C (for legacy codebases/people who already experts in objective-c and don't want to switch), and some other, slower languages that will always be second class.
That would mean its fate would be tied to iOS, which is used only on phones built by a single company. When that company stopped producing mobile phones, or decided to use a different operating system, the language would die.
I would be inclined to say no, it's rather unlikely, short of apple somehow suddenly going bankrupt.
A lot of the tools in the modern ops ecosystem are written in Go, and that trend is not slowing down. Not even going to start to list them. A lot of devs also love Go and it has a very nice community. If you would have said this 5 years ago? Sure - but now it's past the 10y mark in age - I think it's safe to say Go isn't going to go away any time soon.
Java and C# are not going anywhere, especially now that .NET works on OSX and Linux. Swift, unlikely. Go, still uncertain.
It's fairly short-sighted to criticize a language and hope it dies out in usage just because a corporation is chiefly responsible for it.
