Dynamic Alert Package for iOS 13 – 14

If you need to create a simple alert popup, read Paul Hudson’s post. (The post also covers how to create alerts in the newer, iOS-15 way.)

I needed a way for a single view to show alerts with one button, with two buttons, and with two buttons and a destructive action (destructive actions are shown in red). I came up with a solution for Fasty, then I wanted to use it in another project, so I put it in a package.

To use:

1. Import the package
2. Add “@State private var alertParams: AlertParams?” to the view that you want to have the Alert.
3. At the bottom of that view, add: “.modifier(AlertModifier(alertParams: $alertParams))”
4. Add the following (or something similar) to the view: Button(“Pop up an alert with one button and an action”) { alertParams = AlertParams(title: “One Button”, message: “One button that calls an action”, primaryButtonLabel: “The button label”) { print(“The user clicked the Alert button”) } }

import SwiftUI
import AlertPopUp_iOS13

struct ContentView: View {
    @State private var alertParams: AlertParams?
    
    var body: some View {
        VStack {
            Button("Pop up an alert with one button and an action") {
                alertParams = AlertParams(title: "One Button", message: "One button that calls an action", primaryButtonLabel: "The button label") { print("The user clicked the Alert button") }
            }
        }
        .modifier(AlertModifier(alertParams: $alertParams))
        .padding()
    }
}

The readMe gives more details.

Here’s a sample project that uses the package.
