Usage:

Simply attach the toast to a view and show it via binding with a 5 sec. delay:

import SwiftUI
import SimpleToast

struct ToastTestView: View {
    @State var showToast: Bool = false

    private let toastOptions = SimpleToastOptions(
        delay: 5
    )

    VStack(spacing: 20) {
        Button(
            action: {
                withAnimation {
                    self.showToast.toggle()
                }
            },
            label: { Text("Show toast") }
        )
    }
    .simpleToast(isShowing: $showToast, options: toastOptions) {
        HStack {
            Image(systemName: "exclamationmark.triangle")
            Text("This is some simple toast message.")            			
        }
        .padding()
        .background(Color.red.opacity(0.8))
        .foregroundColor(Color.white)
        .cornerRadius(10)
    }
}

NOTE: The toast respects the frame of the view it is attached to. Make sure the view has enough room to render the toast. Preferably the view should be attached to the most outer view or the navigation view, if available.

To run custom code after the toast did disappear you just simply have to pass a function to the completion parameter:

import SwiftUI
import SimpleToast

struct ToastTestView: View {
    @State var showToast: Bool = false

    private let toastOptions = SimpleToastOptions(
        delay: 5
    )

    VStack(spacing: 20) {
        Button(
            action: {
                withAnimation {
                    self.showToast.toggle()
                }
            },
            label: { Text("Show toast") }
        )
    }
    .simpleToast(isShowing: $showToast, options: toastOptions, completion: onToastComplete) {
        HStack {
            Image(systemName: "exclamationmark.triangle")
            Text("This is some simple toast message.")                        
        }
        .padding()
        .background(Color.red.opacity(0.8))
        .foregroundColor(Color.white)
        .cornerRadius(10)
    }

    // This will be called on toast completion
    func onToastComplete() -> Void {
        print("The toast did disappear")
    }
}

Options

The toast can be configured via an optional SimpleToastOptions object. If nil is given the default values are taken.

The struct has the following signature:

public struct SimpleToastOptions {
    var alignment: Alignment = .top
    var hideAfter: TimeInterval? = nil
    var showBackdrop: Bool? = true
    var backdropColor: Color = Color.white.opacity(0.9)
    var animation: Animation = .linear
    var modifierType: SimpleToastModifierType = .fade
}

alignment: Defines the alignment of the toast. See https://developer.apple.com/documentation/swiftui/alignment for more information.

hideAfter: Optional parameter to define when the toast disappears. If nil is given the toast won't disappear.

showBackdrop: Optional parameter to define if the toast is rendered over a backdrop.

backdropColor: Optional parameter for the backdrop color

animation: Optional parameter for the animation type. See https://developer.apple.com/documentation/swiftui/animation for more information.

modifierType: Optional parameter for determining the type of toast animation. Possible values(.slide, .fade), default: .fade
