There is a new, compact tab bar that floats at the bottom of the screen so users can easily swipe between tabs. Controls are now easier to reach with one hand and give more focus to a webpage's content. When a Focus is set on one Apple device, it automatically applies to other Apple devices. iOS will suggest a Focus for different occasions, such as work hours or winding down for bed, using on-device intelligence, but users can also create a custom Focus. When a user's Focus is blocking incoming notifications, their status will be displayed to others in Messages. To reduce distraction, a notification summary collects notifications together for delivery at an appropriate time and arranges notifications by priority.įocus is a new feature that can filter notifications and apps based on what a user wishes to focus on at a certain time. Notifications have been redesigned in iOS 15, adding contact photos for people and larger icons for apps. iOS 15 introduces new features for FaceTime calls, tools to reduce distractions, a new notifications experience, added privacy features, complete redesigns for Safari, Weather, and Maps, and more. One interesting aspect of async/await (and the Task type that we need to use to wrap such code when calling it from a synchronous context) is how objects and values often end up being implicitly captured while our asynchronous code is being executed.įor example, let’s say that we’re working on a DocumentViewController, which downloads and displays a Document that was downloaded from a given URL.Apple in June 2021 introduced the latest version of its iOS operating system, iOS 15, which was released on September 20, 2021. While Swift’s relatively new async/await syntax does make many kinds of asynchronous operations easier to write, it still requires us to be quite careful when it comes to managing the memory for the various tasks and objects that are involved in such asynchronous code. Managing an app’s memory is something that tends to be especially tricky to do within the context of asynchronous code, as various objects and values often need to be captured and retained over time in order for our asynchronous calls to be performed and handled.
