Binding Optionals in SwiftUI
August 9, 2020
I’ve been working a lot with SwiftUI lately, and one issue I keep running into is dealing with binding to an Optional
state value. So I wrote these simple little Binding
extensions (they should be self-explanatory) — I hope you find them useful!
import SwiftUI extension Binding { init(forceUnwrapping optional: Binding<Value?>) { self.init( get: { optional.wrappedValue! }, set: { optional.wrappedValue = $0 } ) } init(unwrapping optional: Binding<Value?>, default: Value) { self.init( get: { optional.wrappedValue ?? `default` }, set: { optional.wrappedValue = $0 } ) } }
Let me know what you think, or if there's a better way to be going about this!
