Splash Screen

Creating Launch screen through storyboard

1. Choose launch screen template

   

2. If launch screen contains image, then

   1. In assets.xcassets, load desired icons

      

3. Use provided views to build up the screen

   

4. Go to app targets → App Icons and Launch Screen

   1. Select the storyboard file name

      

   Creating Launch screen programmatically

   1. New SwiftUI View template

   2. In the new file

   struct LaunchScreen: View {
       @State private var isActive = false
       var body: some View {
           ZStack {
               if isActive {
                   ContentView()
               } else {
                   VStack(alignment: .center) {
                       Text("Shopping App")
                           .font(.title)
                           .bold()
                       Image("Bag")
                   }
               }
           }
           .onAppear {
               DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
                   self.isActive = true
               }
           }
       }
   }

   3. In main file

import SwiftUI

@main
struct LaunchScreenDemo: App {
    var body: some Scene {
        WindowGroup {
            LaunchScreen()
        }
    }
}

3. Launch screen with animation

struct LaunchScreen: View {
       // Initial position above the screen
    @State private var firstImageOffset: CGFloat = -100 
       // Initial position below the screen
    @State private var secondImageOffset: CGFloat = UIScreen.main.bounds.height
    @State private var showThirdImage = false
    @State private var isActive = false
    
    var body: some View {
        ZStack {
            if isActive == true {
                ContentView()
            } else {
                GeometryReader { geometry in
                    ZStack {
                        Image("ImageFromAbove")
                            .resizable()
                            .frame(width: 210, height: 260)
                            .offset(x: geometry.size.width/2 - 100, y: firstImageOffset)
                            .onAppear {
                                withAnimation(Animation.easeInOut(duration: 2)) {
                                    firstImageOffset = geometry.size.height / 2 - 100 // Center of the screen
                                }
                            }
                        Image("ImageFromBelow")
                            .resizable()
                            .frame(width: 210, height: 260)
                            .offset(x: geometry.size.width/2 - 100, y: secondImageOffset)
                            .onAppear {
                                withAnimation(Animation.easeInOut(duration: 2)) {
                                    secondImageOffset = geometry.size.height / 2 - 100 // Center of the screen
                                    DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
                                        showThirdImage = true
                                    }
                                }
                            }
// Sometimes this is not necessarry, it all depends how the two images above are colliding
                        if showThirdImage {
                            Image("FinalImage")
                                .resizable()
                                .frame(width: 200, height: 200)
                                .offset(x: geometry.size.width/2 - 100, y: geometry.size.height / 2 - 100)
                        }
                    }
                }
            }
        }
        .onAppear {
            DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
                self.isActive = true
            }
        }
    }
}
