Here's what I found about implementing SwiftUI animations for your iOS app:

**Documentation**: The official Apple documentation on SwiftUI animations explains that you can use implicit animations with the `.animation` modifier or explicit animations with the `withAnimation` function. For example, to animate a view's opacity change:
```swift
Text("Hello, World!")
    .opacity(show ? 1.0 : 0.0)
    .animation(.easeInOut(duration: 1.0), value: show)
```

**Code Examples**: Apple provides several code examples demonstrating different animation techniques. One example shows how to create a custom transition animation:
```swift
struct ContentView: View {
    @State private var isPresenting = false

    var body: some View {
        ZStack {
            if isPresenting {
                RoundedRectangle(cornerRadius: 25.0)
                    .fill(Color.blue)
                    .frame(width: 200, height: 200)
                    .transition(.asymmetric(
                        insertion: .scale,
                        removal: .opacity
                    ))
            }
        }
        .onTapGesture {
            withAnimation {
                isPresenting.toggle()
            }
        }
    }
}
```

**WWDC Videos**: The WWDC 2021 session 'SwiftUI: Implementing Real-World Apps' (https://developer.apple.com/videos/play/wwdc2021/10112/) provides an in-depth look at implementing animations in real-world SwiftUI apps. Another relevant session is 'SwiftUI: Data Essentials' from WWDC 2020, which covers data flow and animations in SwiftUI.
