App Store search no longer shows 32-bit apps; 64-bits only with iOS 11?
So if you're Apple, the best way to get developers to remember anything is to hit them where it hurts the most, which is in their wallets. Apple has contractually agreed to certain payout percentages so those can't be changed. But what Apple has done is to remove 32-bit apps from appearing on search results for the App Store. That makes these apps somewhat invisible, which does have a negative effect on developers' paychecks.
There is some speculation that at WWDC (which starts this Tuesday, June 5th), Apple is going to announce that iOS 11 will support 64-bit apps only. That would make sense and explain why Apple is no longer showing 32-bit apps in App Store search results. Developers who don't get the message will end up losing their listing in the App Store.
The end of the line for 32-bit apps started with the Apple iPhone 5s in September 2013, which featured the Apple A7 chipset and its 64-bit CPU. Among iOS builds, iOS 7 was the first to run 64-bit apps.
And now Apple is expected to put the kibosh on 32-bits. The only advantage for iPhone users, besides the ability of apps to handle more complex math equations if needed, would be the ability of iOS devices to support more than 4GB of RAM. Considering that the Apple iPhone 8 will have 3GB of RAM, that doesn't appear to be an issue now.
