Whats New in the iOS 15

In iOS 15 SDK, you can build apps that create new kinds of shared experiences with SharePlay and the Group Activities API. Swift 5.5 introduces concurrency support, built into the language with async/await and Actors.

SharePlay and Group Activities API

SharePlay offers a new way for people to share your app. Media streaming apps can let users share content through the new Group Activities API with full-fidelity video and all syncing handled by the system.

Focus and notifications

With Focus, users can have notifications delivered at times that work best for them, and with the Interruption Levels API, you can provide more nuanced delivery with one of four interruption levels.

Gain more control over lower-level drawing primitives with the new Canvas API, a modern, GPU-accelerated equivalent of drawRect.

UIKit

this introduces sheet presentation controllers, which let you present your view controller as a customizable, resizable sheet. UIKit provides new APIs for configuration buttons, displaying pop-up buttons, a new chromeless bar appearance, image decoding, and creating a thumbnail version of an image.

RealityKit

Turn photos from your iPhone or iPad into high-quality 3D models that are optimized for AR in minutes using the new Object Capture API on macOS.

Create ML

Create ML is now available as a Swift framework on iOS and iPadOS, in addition to macOS. You can programmatically experiment and automate model creation in Swift scripts or playgrounds. Build dynamic app features that leverage Create ML APIs to train models directly from user input or behavior on-device.

Core ML

a new, future-looking model format that provides the flexibility to edit metadata and visibility to track changes with source control.

Tabular Data

Tabular Data makes it easy to programmatically import information from JSON and CSV files and prepare datasets ready for Core ML, Create ML, or your own custom solution. Use Tabular Data’s central DataFrame API to sort, join, group, split, encode, decode, explode, filter, slice, combine, and transform the rows and columns of your tabular data to meet your needs.

Sound Analysis

Sound Analysis adds a new sound classifier that your apps can use to identify over 300 unique sounds from live audio or an audio file. A new time window duration API gives you tune prediction accuracy versus time precision.

GameKit

• GameKit provides new ways to discover and invite players to participate in a game. Players can now invite contacts, message groups, and anyone with a phone number or email address.
• Players see the status of other players receiving and accepting invitations.
• And, optionally, start with a minimum number of players while waiting for others to join.

Game Controller
