I'm wondering if we need something similar to TCA IfLetStore
public struct IfLetBinding<State, Action, IfContent: View, ElseContent: View>: View {
public let binding: LoopBinding<State?, Action>
public let ifContent: (LoopBinding<State, Action>) -> IfContent
public let elseContent: () -> ElseContent
public init(
_ binding: LoopBinding<State?, Action>,
then ifContent: @escaping (LoopBinding<State, Action>) -> IfContent,
else elseContent: @escaping @autoclosure () -> ElseContent
) {
self.binding = binding
self.ifContent = ifContent
self.elseContent = elseContent
}
public var body: some View {
Group<_ConditionalContent<IfContent, ElseContent>> {
if let state = binding.wrappedValue {
return ViewBuilder.buildEither(
first: self.ifContent(
self.binding.scoped(
to: { $0 ?? state },
event: { $0 }
)
)
)
} else {
return ViewBuilder.buildEither(second: self.elseContent())
}
}
}
}
I've been playing with it here
from loop.
