Convert SwiftUI Optional Binding to Non-Optional Binding

Binding+NonOptional.swift

extension Binding {
    public init(wrappedValue: Binding<Value?>, defaultValue: Value) {
        self = Binding<Value>(
            get: { wrappedValue.wrappedValue ?? defaultValue },
            set: { wrappedValue.wrappedValue = $0 }
        )
    }
    
    public func defaultValue<T>(_ value: T) -> Binding<T> where Value == T? {
        Binding<T>(
            get: { wrappedValue ?? value },
            set: { wrappedValue = $0 }
        )
    }
}

Usage:

@Binding private var name: String?
// …
TextField(“”, text: $name.defaultValue(“”))

Particularly useful when dealing with CoreData objects:

@ObservedObject var model: Model
TextField(“”, text: $model.name.defaultValue(“”))
