The safe area is one of the most relevant changes in the UI paradigm of iOS in the recent years. Let's learn how to implement a footer with CTA that respects the safe areas but with a background that extends to the edge.
Swift type system is quite powerful and the where clause is a very important part of how developers interface with it. This keyword allows developers to constraint code to a...
Swift 5.3 comes with a nice addition for enums: it will synthesize the required implementation to conform to the Comparable protocol. This reduces a lot the boilerplate needed to make...
A couple of weekends ago I was reading my Twitter timeline and I, don't know how, ended up in this old tweet."This isn't a Louie Mantia color."(That means it isn't...

The abstractions on SwiftUI are so composable that customising the UI it's basically an intrinsic property of the framework. Let's take a quick look at some things you can do...
