I followed a tutorial to get a nice animation with startup of the app. But the tutorial wasn't in ios15 or newer. So there was some depricated stuff in it like animation. One of them i got fiex but one keep getting problems with.

    var body: some View {
        VStack {
            ZStack {

                // Content
                if currentUserSignedIn {
                    tabView
                        .transition(.asymmetric(insertion: .move(edge: .bottom), removal: .move(edge: .top)))
                } else {
                    OnboardingView()
                        .transition(.asymmetric(insertion: .move(edge: .top), removal: .move(edge: .bottom)))
                }

                // Splash
                ZStack {
                    Color(color)

                    Image("JobIcon_white")
                        .resizable()
                        .aspectRatio(contentMode: .fit)
                        .frame(
                            width: 85,
                            height: 85
                        )
                        .scaleEffect(animate ? 50 : 1)
                        .animation(.easeOut(duration: 0.5), value: 50)
                }
                .edgesIgnoringSafeArea(.all)
                .animation(.linear(duration: 0.3))
                .opacity(showSplash ? 1 : 0)
            }
        }
        .onAppear {
            DispatchQueue.main.asyncAfter(deadline: .now() + 0.3) {
                animate.toggle()
            }

            DispatchQueue.main.asyncAfter(deadline: .now() + 0.7) {
                showSplash.toggle()
            }
        }
    }

It's this line that's the problem: .animation(.linear(duration: 0.3))

if you have a boolean that controls the animation try the below

.animation(.linear(duration: 0.3), value: YourBoolean)

But when i add a bool the animation doesn't work anymore

Even if you toggle the boolean?

@maarten is wrestling with animation.

I think this animation doesn't work because you base the animation on a light switch that never changes.

TLDR: value: 50 doesn't change, so the animation doesn't fire.

@State private var shouldAnimate = true
Image("JobIcon_white")
    .scaleEffect(shouldAnimate ? 50 : 1)  // <- Choose 50 or 1 based on shouldAnimate boolean
    .animation(.easeOut(duration: 0.5), value: 50)  // <- Start the animation when value '50' changes
    // Plot twist!   The value never changes!

Try this?

@State private var shouldAnimate = true
Image("JobIcon_white")
    .scaleEffect(shouldAnimate ? 50 : 1)  // <- Choose 50 or 1 based on shouldAnimate boolean
    .animation(.easeOut(duration: 0.5), value: shouldAnimate)  // <- Start the animation when value shouldAnimate changes
