In theory, Mac’s Mach-O executable format supports multi-architecture binaries that can work on both arm64 and x86_64. But I know nothing about Apple’s plans to drop support for x86_64 in X-Code. After this happen, developers will provide arm64-only binaries.

It’ll probably happen in the next few years. Compiling for PowerPC went away after macOS dropped it, and it was the same story for i386. Running and targeting x86_64 will soon be a distant memory. That being said, if you have a Mac/Hackintosh/VM with an older Xcode, keep it! You can still compile with the old version, compile with the new version, and stick the results together with the lipo command. I wrote a simple C CLI app and I can put five architectures in one binary if I want (ppc, ppc64, i386, x86_64, arm64) and it’ll run on any macOS/Mac OS X version ever made.
