If you want to use Member(memberId: 14, fullName: "Nifras", photoUrl: "Hello") syntax, you have to create struct Member:

struct Member {
    memberId: Int64?
    fullName: String?
    photoUrl: String?
}

You can read more about structures https://docs.swift.org/swift-book/LanguageGuide/ClassesAndStructures.html

Member is an alias for a tuple. You are trying to create an instance of a Member like calling an initializer for a class or struct.

You want:

let someVar: Member = (14, "Nifras", "Hello")

Or you can use Member as a type for a parameter or return type.

func someFunc(someParam: Member)

or

func someFunc() -> Member
