Async means asynchronous we can add it as method attributes.
There are two steps to perform for async/await: make a function using the async keyword & call it using await keyword.

As the name suggests, it is a way to write complex asynchronous code if it is synchronous. Concurrency means running multiple chunks of code at the same time. Swift 5.5 introduced changes in the concurrency system using async/await. Location data access will expire once the user or system terminates the app. Once the location access is granted, even if the application is in the background, it will get location data. If the user has denied permission for the first time, when the user clicks on the location button next time, it will give access to the current location without asking for a permission alert. Whenever users open the app again, the user can simply click on the location button & it will give access to the current location without asking for permission alert. So, the first time it will ask the user for permission. They are providing location button UI by default. So, whenever a user tries to access the location, it asks for permission. In iOS 13, new location permission was introduced to access it only once. the default image view tintColor is blue): let im UIImage(systemName:'circle.fill').withTintColor(.red) let iv UIImageView(image:im) self.view. singleSelection It will allow only 1 item as selected in the menu or submenu.ītnMenu.showsMenuAsPrimaryAction = true 3. destructive option in UIMenu, we can show the submenu. The options in UIMenu are used to show how the menu will be shown. The state in UIAction is used to show a checkmark to show selection. UIMenu takes the title, image, options, handler & other parameters. UIAction takes the title, image, attributes, state & handler as its parameters. Using UIMenu, we can create an instance of the menu it has a parameter called children that can take an array of UIMenu & UIAction. So, iOS 15 introduced UIMenu with SubMenu added to it. IOS 14 introduced UIMenu, but if you want to add a submenu, it was not possible in iOS 14.

We can access the sheetPresentationController property to get the instance of UISheetPresentationController for customizing its appearance. UIViewController has a new property called sheetPresentationController you can present the bottom sheet. It has customization like height adjustment, adding a grabber to the top of the sheet. In iOS 14, they introduced this, but it didn’t have any customization, but from iOS 15, we can implement apple maps like a bottom sheet with a smaller height. UISheetPresentationControllerĪpple provided some new API improvements in WWDC 21 to present the bottom sheets. In this blog post, we will learn a few new features that have been introduced and see how we can implement them in our code. Apple has made sure while introducing the new features in iOS 15 and Swift 5.5 that every developer can build the best interactive applications with minimal time and effort. At Worldwide Developers Conference 21, Apple has overcome many limitations by announcing some important features for developers.
