AlertToast-SwiftUI

Present Apple-like alert & toast in SwiftUI

Example

Overview

Currently in SwiftUI, the only way to inform the user about some process that finished for example, is by using Alert. Sometimes, you just want to pop a message that tells the user that something completed, or his message was sent. Apple doesn't provide any other method rather than using Alert even though Apple using all kinds of different pop-ups. The results are poor UX where the user would need to tap "OK/Dismiss" for every little information that he should be notified about.

Alert Toast is an open-source library in Github to use with SwiftUI. It allows you to present popups that don't need any user action to dismiss or to validate. Some great usage examples: Message Sent, Poor Network Connection, Profile Updated, Logged In/Out, Favorited, Loading and so on...

• Built with pure SwiftUI.
• 3 Display modes: Alert (pop at the center), HUD (drop from the top) and Banner (pop/slide from the bottom).
• Complete, Error SystemImage, Image, Loading, and Regular (Only Text).
• Supports Light & Dark Mode.
• Works with any kind of view builder.
• Localization support.
• Font & Background customization.

If you like the project, don't forget to put star 🌟.

Usage

First, add import AlertToast on every swift file you would like to use AlertToast.

Then, use the .toast view modifier:

Parameters:

• isPresenting: (MUST) assign a Binding<Bool> to show or dismiss alert.
• duration: default is 2, set 0 to disable auto dismiss.
• tapToDismiss: default is true, set false to disable.
• alert: (MUST) expects AlertToast.

Usage example with regular alert

import AlertToast
import SwiftUI

struct ContentView: View{

    @State private var showToast = false

    var body: some View{
        VStack{

            Button("Show Toast"){
                 showAlert.toggle()
            }
        }
        .toast(isPresenting: $showToast){

            // `.alert` is the default displayMode
            AlertToast(type: .regular, title: "Message Sent!")
            
            //Choose .hud to toast alert from the top of the screen
            //AlertToast(displayMode: .hud, type: .regular, title: "Message Sent!")
            
            //Choose .banner to slide/pop alert from the bottom of the screen
            //AlertToast(displayMode: .banner(.slide), type: .regular, title: "Message Sent!")
        }
    }
}

Complete Modifier Example

.toast(isPresenting: $showAlert, duration: 2, tapToDismiss: true, alert: {
   //AlertToast goes here
}, onTap: {
   //onTap would call either if `tapToDismis` is true/false
   //If tapToDismiss is true, onTap would call and then dismis the alert
}, completion: {
   //Completion block after dismiss
})
