Why can't I use the short Array constructor syntax when creating an Array of a nested Struct? [duplicate]

Answer 1

It's just a hole in the language. After all, the [Type] syntax is just syntactic sugar; as you rightly say, if you use the real syntax with Array<Type>, or use [Type] but not as a constructor, there's no problem. You can also work around it with type alias:

struct Struct1 {
    struct Struct2 {
        var name: String?
    }
}

typealias Struct2 = Struct1.Struct2

var struct2Array = [Struct2]()
