Download the project from GitHub, open the .playground file in Xcode, and run each page via the play button. Note that it was last updated in 2015, so you might need an older Xcode version or adjust code for compatibility.

Question 2

Study the 'iOS Calculator' and 'Calculator' pages in the playground, which use nested UIStackViews for rows and columns. Adapt the distribution and alignment settings to replicate similar button grids in your app.

Question 5

Can I use UIStackViewPlayground with SwiftUI projects?

Accepted Answer

No, this playground is specific to UIKit and UIStackView. For SwiftUI, you'll need resources on VStack, HStack, and other SwiftUI layout modifiers, as the concepts don't directly translate.
