Swift: How do I add struct instances in a class to an array in another struct

Question

I have two structs and a class. when I call on the class in which I have created instances for one of the structs. I want to append them to an array in the other struct when the class is called. Is there a way to do this?

struct People {
    let name: String
    let age: Int
}

struct Group {
    var groupOfPeople: [People] = []
}

class example {
    var group1 = Group()
    let person1 = People(name: "Jay", age: 44)
    let person2 = People(name: "Sarah", age: 35)
    let person3 = People(name: "Eric", age: 21)
    let person4 = People(name: "Tara", age: 10)
    group.groupOfPeople.append(contentsOf: [person1, person2, person3, person4])
}

This won't work, is there another way to do it?

Is it group1 or group?

You can't execute code like that in the class body, it needs to be in the scope of a function or a constructor.

To me it looks like you want to do something like

class Example {
    func runExample() {
        var group1 = Group()
        let person1 = People(name: "Jay", age: 44)
        let person2 = People(name: "Sarah", age: 35)
        let person3 = People(name: "Eric", age: 21)
        let person4 = People(name: "Tara", age: 10)
        group1.groupOfPeople.append(contentsOf: [person1, person2, person3, person4])
    }
}

And then

let example = Example()
example.runExample()

    var group1 = Group()
    let person1 = People(name: "Jay", age: 44)
    let person2 = People(name: "Sarah", age: 35)
    let person3 = People(name: "Eric", age: 21)
    let person4 = People(name: "Tara", age: 10)

    init() {
        group1.groupOfPeople = [person1, person2, person3, person4]
    }

}
