Bindings are a core concept in SwiftUI. We can easily convert a @State property wrapper to a binding of its value, and we can traverse keypaths to get Bindings of nested values. What if we wanted to transform the values, or update values inside of collections? In this episode we will explore creating map for transforming bindings, unwrap for transforming optional bindings, and take a look at how bindings with collections work under the hood.
