LibraryContentProvider protocol in Xcode is a way for adding custom views and view modifiers to the Xcode library, which enables drag and dropping them to the SwiftUI preview. Xcode automatically… Read more LibraryContentProvider in Xcode →
Recently I was asked a question about creating an app which has SwiftUI views but no navigation logic in it. Instead, UIKit controls how views are presented. It is a fair question since SwiftUI views have navigation support, but not everything is there if we need to support previous iOS versions as well, or we have a case of an app which have both UIKit and SwiftUI views. Therefore, let’s take a look at on one approach, how to handle navigation on the UIKit side but still use SwiftUI views.… Read more UIKit navigation with SwiftUI views →
SwiftUI has a Picker view available with multiple different styles. One example of when it falls short is when we want to use a multi component picker with wheel style. One way how to try to achieve this is using a HStack with two Picker views, but it does not work very well, especially when trying to show it inside a Form view. So what else we can do? If something can’t be done in SwiftUI then we can use UIKit instead. In my case, I wanted to create a… Read more Using a multi component picker in a SwiftUI form →

If we want to spice up the user interface, then we can make some titles in the app to use gradient colours. In WWDC’21 Apple introduced an API for making gradient text styles easy to create. The .foregroundStyle() view modifier takes in a type which conforms to ShapeStyle protocol. One of these types are gradient types in SwiftUI. Therefore, creating a fun gradient text is a matter of creating a text and applying a foregroundStyle view modifier with a gradient on it. The new view modifier is great, but it… Read more Gradient text in SwiftUI →
WWDC’21 introduced APIs for managing focus in SwiftUI. When dealing with multiple focusable views, we can create an enum for representing these and use the new @FocusState property wrapper along with focused() view modifier, where each of the focusable view binds its focus to an enum case. This can look like this: In this example we have FormEntry enum which represents focusable elements in the view. Each of the view has a focused() view modifier, which binds the current focus state to the text field if it matches with the… Read more Focusing views in SwiftUI →
TabView is a container view which enables navigating between multiple flows by selecting one of the items on the tab bar. Tapping on a tab item replaces the visible view with a view associated with the item. Tab view is set up by creating views which have tab items attached. Tab items are created with the tabItem() view modifier, which supports setting a text and an image. In addition, there is a badge() view modifier if we would like to show a badge on top of the item. Tab view… Read more Tab view in SwiftUI →
Xcode provides a cross-platform app template in SwiftUI which can be built for macOS and iOS. This template includes a Shared folder which is meant for code used both on macOS and iOS. Many SwiftUI types and functions work both on macOS and iOS but along with developing an app we’ll encounter cases where we need to specialize per platform. When I was building a multiplatform app then the very first thing I encountered was list styles. On macOS I wanted to use a different list style than on iOS… Read more Structuring platform specific code in SwiftUI →
