protocol UserType {
  var name: String { get }

  var name = "sadf"
  var age: Int = 12

Well I assume you want to let the struct Person conform to the protocol UserType So first you need to add

: UserType

so it becomes like this

struct Person: UserType {
    var name = "sadf"
    var age: Int = 12
}

Then you want to create a constant called somePerson that is of type Person. But you got it confused with the computed properties. So you need to replace

let somePerson: Person {
  return "\(name) \(age)"
}

with

let somePerson: Person = Person(name: "Foo", age: 13)
