Render advanced 3D graphics and perform data-parallel computations. Get fine-grained access to the GPU while minimizing CPU overhead. The Metal Framework provides extremely low-overhead access to the GPU, enabling incredibly high performance for your sophisticated graphics rendering and computational tasks. Metal eliminates many performance bottlenecks—such as costly state validation—that are found in traditional graphics APIs. Metal moves all expensive state translation and compilation operations out of the critical path of your most performance sensitive rendering code. It provides precompiled shaders, state objects, and explicit command scheduling to ensure that your application achieves the highest possible performance and efficiency. Graphics, compute, and blit commands can be used together seamlessly and efficiently. Metal is specifically designed to exploit modern architectural considerations, such as multiprocessing and shared memory, to make it easy to parallelize the creation of GPU commands.

The powerful programming language that is also easy to learn. Swift is a powerful and intuitive programming language for macOS, iOS, watchOS and tvOS. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.

Create, distribute, and update passes for the Wallet app. Request and process Apple Pay payments in your app. The PassKit framework lets you add and manage passes in the user’s Wallet app. The Wallet app allows users to organize their boarding passes, tickets, gift cards, and loyalty cards. Using the PassKit framework, you can add passes to Wallet and have these passes appear on the user’s lock screen based on the time and place when the pass is relevant. You can also update a pass’s content using push notifications. Additionally, Wallet manages the user’s credit cards for Apple Pay. The PassKit framework also supports in-app payments for physical goods and services using Apple Pay. For digital goods and services delivered within the app, see In-App Purchase Programming Guide instead.

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data.
