The integer value passed to the cornerRadius modifier corresponds to the roundness of the corner, with higher numbers corresponding to more rounded corners. To do rounded corner images, use the cornerRadius modifier. Shape of Images Image("Image Asset Name") Note that if the frame modifier is used without the resizable modifier, the image is not resized, but instead the image display is cropped. The alignment parameter indicates how the Image will be placed in the frame, which is useful if the frame is larger than the Image. To further change the size of an Image, the frame modifier can be added with parameters width and height to specify the new dimensions. frame(width: 300, height: 300, alignment. fill) on lines 7 and 8 both rescale the image so that the image fills the entire screen or its frame. The modifiers scaledToFill and aspectRatio(contentMode. ![]() fit) on lines 3 and 4 are the same, they both rescale the image to maintain its original aspect ratio and fit on the screen or its frame. The modifiers scaledToFit and aspectRatio(contentMode. Aspect Ratio of Images Image("Image Asset Name") More modifiers can be added to further resize the image, as demonstrated and explained below. This makes the image fit into the screen area. To resize an image, the resizable modifier should be added. To display an image, simply add the image file into your asset library (Assets.xcassets) and then pass the name of the asset as a string to your Image element in Line 1. static let dateFormatter : DateFormatter = Īdd leftBarButtonItem or leftBarButtonItems.Buffer Basic Code Example Image("Image Asset Name") Actually this is not SwiftUI feature, but Swift 5 String interpolation.

No matter what technologies you choose, one thing I can assure you is you can create a great app out of either one of them. I suggest you try both of them and judge for yourself which paradigm you like the most. Both UIKit and SwiftUI are different beasts with different ways of thinking. Too bad I don't have the answer to this question. If I can learn one thing today, what would it be UIKit or SwiftUI? I expect both to coexist for a long time, SwiftUI is very young and needs years to grow to be able to replace its ancestor. Apple just introduces SwiftUI, and it already looks great. Not right now, but I can see it might in the future. You need to come back to UIKit when you hit a roadblock. IOS 14 closing some gap, but the point remains. At the current stage, SwiftUI is still missing many features, and I think even you start fresh with SwiftUI, you still need to come back to UIKit from time to time. Yes, UIKit would still be an important part of the iOS world for quite some time. So the best case would be a year until you can get a hand on this lovely SwiftUI.Ī new WidgetKit framework in iOS 14 is exclusive to SwiftUI, so you might need to learn it this year if you want to support a new widget. Because most client work would like to support as much as users as possible, that means you have to work on an app that supports iOS N-1, N-2, or worse N-3. If you plan to find a job or work on a client project in which you have no control over this OS version, you might want to wait a year or two before considering moving to SwiftUI. If you work on a new app that plans to target only the mentioned OS, I would say yes. It depends since SwiftUI runs on iOS 13, macOS 10.15, tvOS 13, and watchOS 6. ![]() ![]() Frequently asked questions about SwiftUI.
