Binding Optionals in SwiftUI
Swift
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!
