Manual installation

ℹ️ Manual installation is not advised anymore. Please use the package version instead.

Usage:

Attach via boolean

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

import SwiftUI
import SimpleToast

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

    private let toastOptions = SimpleToastOptions(
        hideAfter: 5
    )

    VStack(spacing: 20) {
        Button("Show toast") {
            withAnimation {
                showToast.toggle()
            }
        }
    }
    .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 toast should be attached to the most outer view or the navigation view, if available.

Attach via optional object

You can trigger the toast via an instance to an optional, which conforms to the protocol Identifiable. If the value is non-nil the toast will be shown. The following example is based on the previous one and also shows the toast for 5 seconds, but this time based on a value on an item.

import SwiftUI
import SimpleToast

struct ToastTestView: View {
    @State var showToast: DummyItem? = nil

    private struct DummyItem: Identifiable {
        var foo: String = "Bar"
    }

    private let toastOptions = SimpleToastOptions(
        hideAfter: 5
    )

    VStack(spacing: 20) {
        Button("Show toast") {
            withAnimation {
                // Toggle the item
                showToast = showToast == nil ? DummyItem() : nil
            }
        }
    }
    .simpleToast(item: $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)
    }
}

ℹ️ This functionality is similar to the one of the SwiftUI sheet(item:onDismiss:content:)

Run code after dismiss

To run custom code after the toast disappeared you just simply have to pass a function to the onDismiss parameter:

import SwiftUI
import SimpleToast

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

    private let toastOptions = SimpleToastOptions(
        hideAfter: 5
    )

    VStack(spacing: 20) {
        Button("Show toast") {
            withAnimation {
                showToast.toggle()
            }
        }
    }
    .simpleToast(isShowing: $showToast, options: toastOptions, onDismiss: 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. You can simply pass an empty object to configure the toast with default values.

📌 All parameters inside the options are optional. If not set, the default value will be taken.

Option	Description	Default
alignment	Defines the alignment of the toast. See https://developer.apple.com/documentation/swiftui/alignment for more information.	.top
hideAfter	Defines when the toast disappears. If nil is given the toast won't disappear.	nil
showBackdrop	Defines if the toast is rendered over a backdrop.	true
backdropColor	Defines the backdrop color	Color.white.opacity(0.9)
animation	Defines the animation type. See https://developer.apple.com/documentation/swiftui/animation for more information.	.linear
modifierType	Defines the type of toast animation. Possible values(.slide, .fade)	.fade

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
}
