The fade comes about due to the fact SwiftUI sees the background shade, icon, and text transforming, so it removes the outdated views and replaces it with new sights.

Idea: Though we’ll be targeting iOS 16, our code will even operate wonderful on macOS Ventura and outside of.

The look canvas you see isn’t just an approximation within your consumer interface — it’s your live app. And Xcode can swap edited code instantly with your live app applying dynamic substitute.

So, incorporate these two modifiers towards the interior VStack, telling SwiftUI to recognize The complete team applying our id residence, and animate its include and removing transitions using a slide:

To get started, you’ll have to download Xcode through the Mac Application Retail store. It’s cost-free, and includes Swift and all the opposite tools you need to abide by this tutorial.
