Android was very easy to start. I learnt kotlin as I was writing the code. Java I remembered some from college days decade ago. The UI builder was very easy to use. I even went far as using the dagger Di.
iOS I was kind of frustrated. I had gone over swift Lang some time back. But I found its syntax estoric. UI builder had its own issues for some row column the constraint layout kept on failing. Its not user friendly as in android. And in the strange name/ structure of routes, the dragging of ui elements to code.Considering that I would need to write business code for both platforms I just gave it up. Now trying out flutter.
I can say however that it is easier to create things of higher quality with the iOS Sdk than it is with the Android sdk, at least it was for me.
