Welcome Sheet

Welcome sheet for iOS enables incredibly easy way for creating onboarding screens, update notes, or whatever you imagine! The main idea standing behind this project was to follow the design of Apple’s native onboarding screens as much as possible, that’s why you can be always sure they will look gorgeous on iPhone SE screen as well as on iPad Pro’s massive 12,9” display!

SwiftUI

To create a welcome sheet in SwiftUI simply add .welcomeSheet view modifier to your view and pass page array as an argument.

import SwiftUI
import WelcomeSheet

struct ContentView: View {
    @State private var showSheet = false
    
    let pages = [
        WelcomeSheetPage(title: "Welcome to Welcome Sheet", rows: [
            WelcomeSheetPageRow(imageSystemName: "rectangle.stack.fill.badge.plus",
                                title: "Quick Creation",
                                content: "It's incredibly intuitive. Simply declare an array of pages filled with content."),
            
            WelcomeSheetPageRow(imageSystemName: "slider.horizontal.3",
                                title: "Highly Customisable",
                                content: "Match sheet's appearance to your app, link buttons, perform actions after dismissal."),
            
            WelcomeSheetPageRow(imageSystemName: "ipad.and.iphone",
                                title: "Works out of the box",
                                content: "Don't worry about various screen sizes. It will look gorgeous on every iOS device.")
        ])
    ]
    
    var body: some View {
        Button("Show sheet") {
            showSheet.toggle()
        }
        .welcomeSheet(isPresented: $showSheet, pages: pages)
    }
}

.welcomeSheet

.welcomeSheet presents welcome sheet with given pages when a binding to a Boolean value that you provide is true.

.welcomeSheet(isPresented: $showSheet, 
              onDismiss: { /* Run this code when sheet is dismissed */ }, 
              isSlideToDismissDisabled: true, 
              preferredColorScheme = .dark,
              pages: pages)

isPresented - bool binding. When set to true presents sheet.
onDismiss - Closure called after sheet's dismissal.
isSlideToDismissDisabled - When set to true disables sheet's swipe to dismiss gesture.
preferredColorScheme - Overrides the default color scheme.
pages - Array of pages to be displayed chronologically.

UIKit

To create a welcome sheet in UIKit create WelcomeSheetController and present it from your ViewController.

class ViewController: UIViewController {

    @IBOutlet weak var showSheetButton: UIButton!

    let pages = [
        WelcomeSheetPage(title: "Welcome to Welcome Sheet", rows: [
            WelcomeSheetPageRow(imageSystemName: "rectangle.stack.fill.badge.plus",
                                title: "Quick Creation",
                                content: "It's incredibly intuitive. Simply declare an array of pages filled with content."),
            
            WelcomeSheetPageRow(imageSystemName: "slider.horizontal.3",
                                title: "Highly Customisable",
                                content: "Match sheet's appearance to your app, link buttons, perform actions after dismissal."),
            
            WelcomeSheetPageRow(imageSystemName: "ipad.and.iphone",
                                title: "Works out of the box",
                                content: "Don't worry about various screen sizes. It will look gorgeous on every iOS device.")
        ])
    ]

    override func viewDidLoad() {
        super.viewDidLoad()

        showSheetButton.addTarget(self, action: #selector(showSheet), for: .touchUpInside)
    }

    @objc func showSheet() {
        let sheetVC = WelcomeSheetController()
        sheetVC.pages = pages
        sheetVC.onDismiss = sheetDismissed

        present(sheetVC, animated: true)
    }

    func sheetDismissed() {
        print("Sheet dismissed")
    }
}

WelcomeSheetController

WelcomeSheetController controller used to create, configure and present the sheet.

let sheetVC = WelcomeSheetController()
sheetVC.pages = pages
sheetVC.onDismiss = { /* Run this code when sheet is dismissed */ }
sheetVC.isModalInPresentation = true

present(sheetVC, animated: true)

pages - Array of pages to be displayed chronologically.
onDismiss - Closure called after sheet's dismissal.
isModalInPresentation - When set to true disables sheet's swipe to dismiss gesture.
