Development for iOS or Android?

Question

Android

In general, I know the basics of Java, I have been studying the Android SDK for a year, I have written a couple of applications.
I myself use only Apple products, over time such problems began to arise, for debugging I needed an Android device, etc.
I started thinking in the direction of starting to learn Swift and, accordingly, questions arose:
Does it make sense? How are things on the market? What is more in demand Android or iOS applications?

Answer 1

1) you are already writing on android, there is nothing shameful to write on a poppy, I have the same poppy, but nevertheless I debug android applications by connecting an anroid tablet
2) Both platforms are in demand, but! android has more penetration, because most phone manufacturers install it, and not only set-top boxes, TVs, watches

Answer 2

I like iOS. There is an easy swift language and a pleasant Xcode development environment. The iOS audience is more active in paying than android.
