Defined in:
lib/apple_frameworks/fat.rb

Overview

Creates “fat” or “universal” libraries by combining two builds of the same library with different architectures.

Note: While it’s possible (and used to be recommended) to make a fat library for multiple platforms (iOS simulator and device), it’s no longer recommended to have these mixed in a single fat binary. For mixing platforms, use ‘XCFramework`.
