Metal

Metal is a low-level, high-performance graphics and compute API developed by Apple for iOS, macOS, tvOS, and visionOS. It provides near-direct access to the GPU, enabling developers to create efficient rendering pipelines and parallel computation tasks with minimal overhead. It is the foundation for graphics in Apple's ecosystem, replacing older APIs like OpenGL ES.

Also known as: Metal API, Metal Framework, Apple Metal, Metal Graphics, Metal Compute

Why learn Metal?

Developers should learn Metal when building high-performance graphics applications, games, or compute-intensive tasks (like machine learning inference) on Apple platforms, as it offers superior performance and efficiency compared to cross-platform alternatives. It is essential for iOS/macOS game development, AR/VR apps using ARKit, and any app requiring real-time 3D rendering or GPU acceleration.
