32-bit app support has been discontinued in Xcode 14
Since June 6, 2022
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.
