I develop for Android professionally and I am quite good at it (now senior dev in a team of 15 android devs). I am growing curious about iOS though. I am currently writing an Android app in my spare time with a friend and our next objective is to learn swift in order to make its iOS counterpart. I have also been offered a couple of iOS jobs (from companies wishing to hire me but not currently hiring for Android). Finally out of our 15 android devs, 2 of them are also iOS devs (and work for us on both platforms). They quite proficient with both platforms (well, Android anyway but I heard no complaints from the iOS team). Sure, they are not as proficient as our best Android engineers, but they are still pulling their weight. Maybe the difference is that we are not an agency but a mobile team working on a single app. We can take the time to learn the platform and teach to our colleagues. Maybe that a freelancer does not have this luxury or the adequate structure.
