我如何快速从一个类中初始化一个元组属性？

Question

I have this property in my class

var service = (String, Int, Bool)

and i need to use a constructor with init, so i have the next code

init()
{
  self.service(1) = "Fix PC"
  self.service(2) = 400
  self.service(3) = false
}

On every line of the init code i got the next message

type of expression is ambiguous without more context

, how can i fix it?

I'm a student, recently using swift, still cant find a solution

That is not the way to assign a value to a tuple. You need to assign the tuple as a whole, you cannot assign its properties 1-by-1.

var service: (String, Int, Bool)

init() {
    service = ("Fix PC", 400, false)
}

Once the tuple is initialised, you can update its members 1-by-1, however your syntax was wrong, tuple member access is done using . , not () .

service.0 = "Fix Mac"

Also, you should only be using tuples as temporary storage, for your example, you should be using a custom type with 3 separate properties.

struct Service {
    let name: String
    let value: Int
    let bool: Bool
}

let service = Service(name: "Fix PC", value: 400, bool: false)
