[swift-users] typealias for Generic in Generic

R is a non generic type, because the generic part is set to T, that’s why R() works.

Otherwise you could create typealias Q<NameThatIsNot_T> = Сarriage<NameThatIsNot_T> and use it like this Q<String>()

I stumbled on ambiguous behaviour of compiler. Is not allowed explicitly indicate type in Generic typealias.

struct Сarriage<T> {
    let g = [T]()
struct Coma<T> {
    typealias R = Сarriage<T>
    let m = R()
    let d = R<String>() \\ error: cannot specialize non-generic type 'Сarriage<T>'
    var b = Сarriage<String>()
    mutatingfunc work() {
        m.g.append(<#T##newElement: T##T#>) \\ what I can write here?
