Universal Binary
A core application distribution format used by Apple during architecture transitions that packages binaries compiled for different CPU architectures (x86_64 and ARM64) into a single executable file, with the operating system automatically selecting the appropriate native code at runtime.
Timeline (last 90 days)
Apple recommends that apps not yet adapted for Apple Silicon begin migration immediately, and recommends building apps as Universal Binaries.
Universal Binary can run natively on both Apple Silicon and Intel architecture Macs simultaneously, supporting the inclusion of both x86_64 and ARM64 code sets.
To build a Universal Binary, Xcode developers typically only need to change the architecture setting to Standard Architectures (arm64, x86_64) and recompile.
The main challenges in building Universal Binary center on whether third-party libraries provide ARM64 versions and compatibility testing for ARM-specific instruction sets.
