swiftui slow performance

To address slow performance in SwiftUI, there are several enhancements and techniques introduced at WWDC 2024 that can help improve your app's performance:

1. Precompiled Shaders: SwiftUI now allows you to precompile shaders before their first use, which helps avoid frame drops caused by lazy shader compilation. This can be particularly useful if your app uses custom visual effects or animations. What’s new in SwiftUI

2. Custom Metal Shaders: You can apply custom Metal shaders directly to SwiftUI views for high-performance rendering. This is useful for creating unique visual effects and can help optimize performance by leveraging the GPU. SwiftUI essentials

3. State-Driven Views: SwiftUI automatically updates the UI when the view state changes, which helps eliminate boilerplate code and update bugs. Ensuring that your views are efficiently managing state changes can improve performance. SwiftUI essentials

4. Efficient Animations: By breaking a view into smaller components that animate individually, you can build more expressive animations and visual effects. This approach can also help improve performance by reducing the complexity of animations. Create custom visual effects with SwiftUI

These improvements and techniques can help you optimize your SwiftUI app for better performance. If you have specific performance issues, consider profiling your app to identify bottlenecks and apply these strategies accordingly.
