The fade happens for the reason that SwiftUI sees the history shade, icon, and text altering, so it gets rid of the outdated sights and replaces it with new views.

Each of such might be accomplished by calling methods to the Circle view. We simply call these look at modifiers

Create advanced animations with expanded animation aid. Use phases to produce sequences of animations, or create several animation tracks applying keyframes. SwiftUI routinely transfers the velocity of a consumer gesture to your animations so your app feels fluid and purely natural.

So, include these two modifiers into the interior VStack, telling SwiftUI to discover The entire group applying our id residence, and animate its incorporate and removal transitions with a slide:

To start, you’ll really need to download Xcode through the Mac Application Retail outlet. It’s cost-free, and comes along with Swift and all the other resources you'll want to follow this tutorial.
