GameplayKit is a collection of foundational tools and technologies for building games in iOS, OS X, and tvOS. Building, evolving, and maintaining a sophisticated game requires a well-planned design—GameplayKit provides architectural tools to help you design modular, scalable game architecture with minimal effort. Creating great games also requires deploying complex algorithms to solve the problems underlying common game mechanics—GameplayKit also provides standard implementations of such algorithms, allowing you to spend more time on the features that make your gameplay unique. Because GameplayKit is independent of high-level game engine technologies, you can combine it with any of those technologies to build a complete game: SpriteKit for 2D games, SceneKit for 3D games, or a custom or third-party game engine using Metal or OpenGL ES. For games with less demanding graphics needs, you can even use GameplayKit with UIKit (in iOS or tvOS) or AppKit (in OS X).

SceneKit is an Objective-C framework for building apps and games that use 3D graphics, combining a high-performance rendering engine with a high-level, descriptive API. SceneKit supports the import, manipulation, and rendering of 3D assets. Unlike lower-level APIs such as OpenGL that require you to implement in precise detail the rendering algorithms that display a scene, SceneKit only requires descriptions of your scene’s contents and the actions or animations you want it to perform.

SpriteKit provides a graphics rendering and animation infrastructure that you can use to animate arbitrary textured images, or sprites. SpriteKit uses a traditional rendering loop where the contents of each frame are processed before the frame is rendered. Your game determines the contents of the scene and how those contents change in each frame. SpriteKit does the work to render frames of animation efficiently using the graphics hardware. SpriteKit is optimized so that the positions of sprites can be changed arbitrarily in each frame of animation.

Sentry’s real-time error tracking gives users insight into production deployments and information to reproduce and fix crashes.

The Accounts framework provides access to user accounts stored in the Accounts database. An account stores the login credentials of a particular service, such as Twitter, that can be used as authentication for the service. By implementing the Accounts framework into your app, you do not need to be responsible for storing account logins yourself. Instead, the user can grant access for your app to use their account login credentials, bypassing the need to type their username and password. If no account for a particular service exists in the user’s Accounts database, you can let them create and save an account from within your app.

AdMob has been rebuilt, leveraging the best of Google's ad platforms. It's designed for app developers, with an intuitive UI to help you start earning from your app quickly, create campaigns in minutes to acquire new users, and gain insights into your app's performance.

The Ad Support framework provides apps with access to an identifier that can be used only for serving advertisements, as well as a flag which indicates whether a user has limited ad tracking. Accessing the advertising identifier requires apps to read and honor the opt-out flag.
