ViewModel
ViewModel is a SwiftUI framework that provides a starting point for your SwiftUI ViewModels. It makes it easier to structure your code and manage the state and behavior of your views.
Usage
To use SwiftUI ViewModel, create a subclass of ViewModel
with Capabilities
, Input
, and Content
types, and implement the content property with the content for the view. You can also provide additional properties and methods to manage the state and behavior of the view.
Here's an example of a simple view model:
class MyViewModel: ViewModel<Void, Void, MyContent> {
@Published private var title: String = "Hello, World!"
override var content: MyContent {
MyContent(title: title)
}
init() {
super.init(capabilities: (), input: ())
}
}
In this example, MyViewModel
has no capabilities or input, and its content is a MyContent
object with a title property set to "Hello, World!".
To use this view model in a view, you can create an instance of MyViewModel
and use its view method to return a view
with the specified content and bindings:
struct MyView: View {
@ObservedObject var viewModel = MyViewModel()
var body: some View {
viewModel.view { content in
Text(content)
}
}
}
Bindings
If you need to have a Binding
for a value, you can define it in the Input
struct of your ViewModel. Here's an example of a ViewModel with Input:
class InputViewModel: ViewModel<Void, InputViewModel.Input, String> {
struct Input {
var textInput: String = ""
}
override var content: String {
input.textInput
}
init() {
super.init(capabilities: (), input: Input())
}
}
To use this ViewModel in a view, you can use the binding
method to get a Binding
for the textInput
property:
struct InputView: View {
@ObservedObject var viewModel = InputViewModel()
var body: some View {
viewModel.view { content in
TextField("Enter some text", text: viewModel.binding(\.textInput))
}
}
}
