TextFieldAlert

A SwiftUI alert with text field(s) for iOS 13+ and tvOS 13+.

As Apple is going to introduce text field(s) as an alert actions in iOS 16, this is a good replacement for older versions.

Requirements

iOS 13.0+ or tvOS 13.0+
Swift 5.1+

Installation

You can add TextFieldAlert to an Xcode project by adding it as a package dependency.

From the File menu, select Add Packages…
Enter https://github.com/sochalewski/TextFieldAlert into the package repository URL text field.
Add the package to your app target.

Usage

TextFieldAlert is exposed through View extension:

func textFieldAlert(
    title: String?,
    message: String?,
    textFields: [TextFieldAlert.TextField],
    actions: [TextFieldAlert.Action],
    isPresented: Binding<Bool>
)

You can use it in your code as follows:

struct ExampleView: View {
    
    @State var isPresented = false
    @State var text1 = ""
    @State var text2 = ""
    
    var body: some View {
        VStack {
            Button {
                isPresented = true
            } label: {
                Text("Alert")
            }
            
            Text(text1)
            Text(text2)
        }
        .textFieldAlert(
            title: "Title",
            message: "Message",
            textFields: [
                .init(text: $text1),
                .init(text: $text2)
            ],
            actions: [
                .init(title: "OK")
            ],
            isPresented: $isPresented
        )
    }
}

More advanced usage (incl. moving the responsibility to a view model, some customization and enabling action buttons conditionally) is available in the Example app.
