However this does not apply to consumer product, e.g. iOS. When building iOS app for simulator, it is running x86_64 natively in the macOS. When building iOS app for device, it is compiled into ARMv64. Cross-compilation happens every day of iOS development. And the process is 99.9% problem-free. The 0.1% problem comes from missing physical feature (e.g. touch screen / gyroscope) rather than instruction set / system issue.
