I am making the complete code available on the gist file referenced below.

The KnobTripleToggleStyle is in itself customizable (i.e., the dot color).

We created an extension on View (.tripleToggleStyle()), for easy setup.

Setting the style on a specific subtree overrides the style set higher in the hierarchy.

We can set the styling in a view higher in the hierarchy, and it will affect its descendants.

We have separated the styling, from the logic.

The code above shows you some interesting accomplishments: tripleToggleStyle(KnobTripleToggleStyle(dotColor. TripleToggle(label: Text("Knob #3"), tripleState: $st) tripleToggleStyle(DefaultTripleToggleStyle()) TripleToggle(label: Text("Default"), tripleState: $st) TripleToggle(label: Text("Knob #2"), tripleState: $st) TripleToggle(label: Text("Knob #1"), tripleState: $st) As you can see, I have created two different styles: one that I call DefaultTripleToggleStyle and the other, named KnobTripleToggleStyle:īy implementing styling, we get to use our custom view, with this simple code: struct ContentView: View private var st: TripleState =.

Now that we know how we can style some of the native views from SwiftUI, let’s explore how we can follow the same styling pattern, on our own custom views.įor this example, we are going to create a three-state toggle switch. In ButtonStyle, for example: public struct ButtonStyleConfiguration ) These properties are commonly referred to as the configuration of the style. The method receives some properties required to implement the logic of the control. For example: func makeBody(configuration: Self.Configuration) -> some View They have a method that creates the view. How Does a Style Work?īuttonStyle, ToggleStyle and all the other styles, are simply protocols. Whatever we do, the logic is still the same.

However, we could change that and replace the dim, with a scale down effect. Its style, on the other hand, can vary: a typical example is a text view that shows the label contents and dims while pressed. When the interaction is complete, a callback function is executed. For example, the logic of a button can be described as an interactive view (usually through a tap or a click). Styles let us alter the appearance of the view, but keep their logic intact. Views and especially controls, usually have a look and a logic. Hopefully, I got your attention, so let’s get on with it.

Finally, and probably the most fun, we’ll learn how to implement the same styling pattern with our own custom controls… not just toggles and buttons. I’ll present the basic setup of a button and a toggle style, but then, we’ll see some aspects that are usually forgotten: how to play nice when inside a Form, and the importance of the accessibility activation point. You probably already experimented with it, and think it is just a trivial exercise… but don’t fly away so soon. In this article, we are going to discuss a simple but useful SwiftUI feature.
