Towards a safer SwiftUI environment

Swift UI's @EnvironmentObject is currently prone to runtime errors. If a view uses an environment object of a type that was not injected using environmentObject a fatalError occurs. This document sketches a design that would support compile-time checking of environment object usage. It requires a few language enhancements.

Tuple intersection types

Swift's protocol composition types such as Protocol1 & Protocol2 are a form of intersection types. Other forms of intersection types are possible. For example, Flow has object intersection types. Tuple intersection types for Swift would be very similar to these.

Below, you can see the examples in the Flow documentation converted to Swift's tuples:

import Combine
import SwiftUI

@dynamicMemberLookup public protocol ViewModelBinding {
    associatedtype State
    associatedtype Input

    var state: State { get }
    mutating func bind(with input: PassthroughSubject<Input, Never>)
}
