The iOS code I write today is largely the same code I would have written 2-3 years ago.
The Android code I write today is largely the same code I would have written 5-7 years ago.
This is because, for the most part, I haven’t kept up with the updates to the languages and frameworks for those platforms.
Some people will respond, “then you’re not a good iOS or Android developer.”
To this I call, BULL.
Newer platform frameworks / features notwithstanding…
