According to apple, starting from [iOS 11](https://developer.apple.com/documentation/uikit/app_and_environment/updating_your_app_from_32-bit_to_64-bit_architecture) and [macOS 10.15](https://support.apple.com/en-us/103076), 32-bit apps are no longer supported. And last release of iOS 11 is in 2018, macOS Catalina in 2022. Now, in 2024, it should be fair to say i386/armv7 darwin/ios is dead, and we can remove 32-bit apple related logic in the tree to reduce maintenance burden.
