I disagree on the locking-in argument. I mean if you decide to program for iOS, you use Swift or Objective C, just as you would use Java to program for Android.

I disagree on the locking-in argument. I mean if you decide to program for iOS, you use Swift or Objective C, just as you would use Java to program for Android. Does the Android community lock developers in by making you use Java? Me thinks not. And in the greater sense, a good developer shouldn't be defined by one programming language, thus the locking-in argument is a bit ridiculous.
