With the release of iOS 17 Beta now available in our real device cloud (US-East, US-West, and EU-Central), mobile app developers should test their apps on this latest version to ensure compatibility with new features such as enhanced security, personalization, sharing, and communication. As Apple dominates the US market share, it's crucial to test iOS 17 before its release in September 2023 alongside the iPhone 15 series. The upcoming update introduces significant changes including privacy and security innovations, Passkey changes, Accessibility API improvements, payment and in-app purchase updates, SwiftUI and VisionOS compatibility checks, and more. To stay ahead of the curve, developers should familiarize themselves with Apple's WWDC sessions library, review relevant APIs, and test their apps on public devices or private devices using Sauce Labs' real device cloud to ensure comprehensive testing coverage.
