Core Principles

1. Always start with the device: MTLCreateSystemDefaultDevice() — every Metal workflow begins here
2. Command pattern: Device → Command Queue → Command Buffer → Command Encoder → Commit
3. Shaders are MSL (Metal Shading Language): C++14-based, with Metal-specific types and attributes
4. Resource management matters: Use appropriate storage modes, avoid unnecessary copies
5. Triple buffering for render loops to keep CPU and GPU in parallel
