The Ultimate Guide to Finding an Alternative to Dismiss in SwiftUI

Posted on

Are you tired of using the traditional dismiss() method in SwiftUI only to find that it’s not working as expected? Or perhaps you’re looking for a more elegant way to dismiss a view in your SwiftUI app? Whatever the reason, you’ve come to the right place! In this comprehensive guide, we’ll explore the alternatives to dismiss in SwiftUI and provide you with clear, step-by-step instructions on how to implement them.

Why Do We Need an Alternative to Dismiss in SwiftUI?

Before we dive into the alternatives, let’s first understand why we need them. The traditional dismiss() method in SwiftUI can be limiting, especially when dealing with complex navigation flows. Some of the reasons why you might want to look for an alternative include:

  • dismiss() can only be used within a NavigationView or a Sheet.
  • It doesn’t provide a smooth transition between views.
  • It can be difficult to customize.

In the following sections, we’ll explore three alternatives to dismiss in SwiftUI that address these limitations.

Alternative 1: Using the @Environment(\.dismiss) Property Wrapper

The first alternative is to use the @Environment(\.dismiss) property wrapper. This method is ideal when you want to dismiss a view from within a NavigationView or a Sheet.


struct MyView: View {
    @Environment(\.dismiss) var dismiss

    var body: some View {
        Button("Dismiss") {
            dismiss()
        }
    }
}

In the above code, we’ve declared a MyView struct that contains a Button with a “Dismiss” label. When the button is tapped, the dismiss() method is called, which dismisses the view.

Alternative 2: Using the @State Property Wrapper and a Binding

The second alternative is to use the @State property wrapper and a binding to dismiss a view. This method is ideal when you want to dismiss a view from a parent view.


struct ParentView: View {
    @State private var is Presented = true

    var body: some View {
        Button("Present View") {
            isPresented.toggle()
        }
        .sheet(isPresented: $isPresented) {
            MyView(isPresented: $isPresented)
        }
    }
}

struct MyView: View {
    @Binding var isPresented: Bool

    var body: some View {
        Button("Dismiss") {
            isPresented.toggle()
        }
    }
}

In the above code, we’ve declared a ParentView struct that presents a MyView struct when the “Present View” button is tapped. The isPresented state variable is used to toggle the presentation of the MyView struct. When the “Dismiss” button is tapped, the isPresented variable is toggled, which dismisses the view.

The third alternative is to use a custom binding and a NavigationLink to dismiss a view. This method is ideal when you want to dismiss a view from a child view.


struct ParentView: View {
    @State private var isPresented = false

    var body: some View {
        NavigationView {
            NavigationLink(destination: MyView(isPresented: $isPresented), isActive: $isPresented) {
                Button("Present View") {
                    isPresented.toggle()
                }
            }
        }
    }
}

struct MyView: View {
    @Binding var isPresented: Bool

    var body: some View {
        Button("Dismiss") {
            isPresented.toggle()
        }
    }
}

In the above code, we’ve declared a ParentView struct that presents a MyView struct when the “Present View” button is tapped. The isPresented state variable is used to toggle the presentation of the MyView struct. When the “Dismiss” button is tapped, the isPresented variable is toggled, which dismisses the view.
