ironSource builds discovery, engagement, monetization and anayltics tools for app developers, device manufacturers, mobile carriers, and advertisers.

The JavaScriptCore Framework allows you to evaluate JavaScript programs from within an Objective-C or C-based program. It also lets you insert custom objects to the JavaScript environment.

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.

Work with image and video assets managed by the Photos app, including those from iCloud Photo Library and Live Photos. Fetch and cache full-sized assets or thumbnails asynchronously, revise content, and sync revisions to multiple devices. In iOS and macOS, the Photos framework provides classes that support building photo editing extensions for the Photos app. In iOS and tvOS, the Photos framework also provides direct access to the photo and video assets managed by the Photos app, including the iCloud Photo Library. Use this framework to retrieve assets for display and playback, edit their image or video content, or work with collections of assets such as albums, moments, and iCloud Shared Albums.

The Watch Connectivity framework (WatchConnectivity.framework) provides a two-way communications conduit between an iOS app and a WatchKit extension on a paired Apple Watch. Apps use this framework to pass files and data back and forth. Most transfers happen in the background when the receiving app is inactive. When the app wakes up, it is notified of any data that arrived while it was inactive. Live communication is also possible when both apps are active.

A software library to view analytics, measure ad performance and build audiences for ad targeting within the Facebook framework.

The Facebook SDK for iOS enables people to sign into your app with Facebook Login. When people log into your app with Facebook they can grant permissions to your app so you can retrieve information or perform actions on Facebook on their behalf.

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.

The UserNotifications framework (UserNotifications.framework) supports the delivery and handling of local and remote notifications. You use the classes of this framework to schedule the delivery of local notifications based on specific conditions, such as time or location. Apps and extensions also use this framework to receive and potentially modify local and remote notifications when they are delivered to the user’s device.
