Swift中按值传递与按引用传递的问题？

func incrementValue(_ value: Int) {
    var newValue = value
    newValue += 1
    print("New value inside function: \(newValue)")
}

var originalValue = 10
incrementValue(originalValue)
print("Original value outside function: \(originalValue)")

New value inside function: 11
Original value outside function: 10

class Person {
    var name: String
    
    init(name: String) {
        self.name = name
    }
}

func changeName(_ person: Person) {
    person.name = "John"
    print("New name inside function: \(person.name)")
}

var person = Person(name: "Tom")
changeName(person)
print("Original name outside function: \(person.name)")

New name inside function: John
Original name outside function: John
