Use of objects and structures in SWIFT

• Object

class Student{



 var name: String = "";

 var age: Int = 0;



 init(name: String ,age:Int) {

 self.name = name

 self.age = age

}

}



let stu = Student(name: "xiao< span style="color: #800000;">", age: 18)

print("Name: \(stu.name)")//Name : Xia

• Structure

struct Person{
    
    var name: String = "";
    var age: Int = 0;
    
    init(name: String ,age:Int) {
        self.name = name
        self.age = age
    }
}

let person = Person(name: "xiao", age: 18)
print("Name: \(person.name)")//Name: xiao

The structure body does not need to consider the reference count. The joint body is a value assignment, that is, a is assigned to b. If you change b, then a remains unchanged, for example

p>

let person = Person(name: "xiao", age: 18)
print("Name: \(person.name)")//Name: xiao
var per1 = person;
per1.name = "da"

print("Name: \(person.name)")//Name: xiao

class Student{



 var name: String = "";

 var age: Int = 0;



 init(name: String ,age:Int) {

 self.name = name

 self.age = age

}

}



let stu = Student(name: "xiao< span style="color: #800000;">", age: 18)

print("Name: \(stu.name)")//Name : Xia

struct Person{
    
    var name: String = "";
    var age: Int = 0;
    
    init(name: String ,age:Int) {
        self.name = name
        self.age = age
    }
}

let person = Person(name: "xiao", age: 18)
print("Name: \(person.name)")//Name: xiao

let person = Person(name: "xiao", age: 18)
print("Name: \(person.name)")//Name: xiao
var per1 = person;
per1.name = "da"

print("Name: \(person.name)")//Name: xiao
