Is the company you work for mostly targeting Apple devices? I'd be interested to hear if there is any large scale Swift usage outside of the Apple ecosystem.

Is the company you work for mostly targeting Apple devices? I'd be interested to hear if there is any large scale Swift usage outside of the Apple ecosystem. If you are targeting Apple devices, was your performance sensitive code always written in Cpp or did you leave Objective-C for Swift+Cpp? Or, were the Cpp parts inherited and just wrapped with whatever your platform's encouraged language was? (I used to do contract iOS work but I stopped around the time Swift came out due to taking a rewarding full-time job, so I never really spent much time on Swift beyond "huh, neat")
