Reproduction
import SwiftUI
struct TextView: View {
@State var text: String = "hello"
func getter() -> String {
return text
}
func setter(_ v: String) {
text = v
}
var body: some View {
TextField("T", text: Binding(get: getter, set: setter))
// Using:
// TextField("T", text: Binding(get:{ return getter() }, set: { v in setter(v) }))
// instead compiles without an issue.
}

Expected behavior
I would expect the compiler to not crash.
Environment
swiftc --version
