Overview
Apple Platform Build is the principle of building llama.cpp as an XCFramework for integration into iOS, macOS, and other Apple platform applications.
Description
This principle covers the build script that produces an Apple XCFramework bundle from the llama.cpp source code. An XCFramework is Apple's format for distributing binary frameworks that support multiple platforms (iOS, macOS, tvOS, etc.) and architectures (arm64, x86_64) in a single bundle. This enables Swift and Objective-C applications on Apple platforms to link against llama.cpp as a pre-built framework.
Usage
Apply this principle when building llama.cpp for distribution as a pre-compiled framework for Apple platform developers, when integrating llama.cpp into Xcode projects, or when creating Swift Package Manager packages that wrap llama.cpp.
Theoretical Basis
XCFramework is Apple's solution for distributing binary frameworks that support multiple platforms and architectures. The build process compiles llama.cpp for each target platform/architecture combination (e.g., iOS arm64, macOS arm64, macOS x86_64, iOS Simulator arm64), then packages the resulting binaries into a single .xcframework bundle. The build script handles CMake configuration for cross-compilation, Metal shader compilation for GPU acceleration on Apple Silicon, and the xcodebuild commands needed to create and validate the framework bundle. This enables downstream developers to add llama.cpp to their Apple platform projects without compiling from source.
