Going to third place means nr1 and 2 spot are Android.
Soon you'll see made for Android first and build for iPhone as an afterthought.
It doesn't matter which "spot" Apple is in.
There are 100 smartphone manufacturers.
99 of them make Android phones.
1 of them makes the iPhone.
And developers still make apps for the iPhone... sometimes exclusively. It's been like this for years.
Being the #2 or #3 manufacturer out of 100 doesn't matter. Apple's ranking on the chart isn't what developers are looking at. They like the iOS development tools and the fact that they make lots of money from iOS.
I know it doesn't make sense to you... but the iPhone is a
very popular platform despite there being vastly more Android phones on Earth.
The smartphone market is fluid... some manufacturers will go up the list... some will go down.
But here's something to remember: Apple was never #1... nor have they ever had an appreciable amount of market share or install base.
Common sense would say Apple's App Store should have never been popular based on those facts.
But it is. And it will continue to be.
Sorry to burst your bubble... but Apple being the #3 smartphone manufacturer won't make developers suddenly drop iOS and start developing for Android exclusively.
If that was the case... developers would have
already done that since there are tons more Android devices on Earth.
But like I said... there's
more to this than just the ranking, market share, install base, etc.
