iOS 17 Is Killing 32-bit App Support!!!

Apple decided to switch to 64-bit. 32-bit apps don’t work anymore

Maybe this article is giving me the wrong impression, but I don't think this is an iOS 17 change. It looks as though Apple got rid of 32-bit support in iOS 11, much as they got rid of 32-bit support in macOS 10.15 (Catalina).

Updating your app from 32-bit to 64-bit architecture – Apple Developer / UIKit

"In iOS 11 and later, all apps use the 64-bit architecture. If your app targets an earlier version of iOS, you must update it to run on later versions."

32 bit apps have been unsupported for a while.

Which app(s) specifically, are you having issues with?

32-bit app support has been discontinued in Xcode 14 - Upcoming Requirements - Apple Developer

"Starting with Xcode 14, the ability to build a single binary with both 32-bit and 64-bit code has been removed. Xcode 14 will only build 64-bit apps. iOS 10, which was released in 2016, was the last version of iOS to run 32-bit apps. As of iOS 11, all 32-bit apps installed on device will not launch."

Perhaps these apps are incompatible with iOS 17 in some other way. Many Mac applications have broken after an operating system upgrade in ways that had nothing to do with 32-vs-64 bit.

I’ve been keeping up with iOS updates. When I updated from iOS 16.7.1 to iOS 17.0.3, my 32-bit apps stopped working. The apps haven’t been updated in 5 years.

Nope. 32 bit apps stopped running with iOS 11.

If you have apps that ran on iOS 16, but don't run on iOS 17, it has nothing to do with 16 or 32 bit...

32 bit apps haven't been supported since iOS 11...

That's 6 years. Apparently you haven't exactly been keeping current with iOS updates.
