Methods are functions that belong to a class or Structures. Methods are called using the . operator.
class Person {
var name: String
var age: Int
init(name: String, age: Int) {
self.name = name
self.age = age
}
func sayHello() {
print("Hello, my name is \(name) and I am \(age) years old.")
}
}let person = Person(name: "Abdi", age: 30)
person.sayHello() // prints "Hello, my name is Abdi and I am 30 years old."Static methods are methods that belong to the class itself. They are called using the class name.
class counter {
static var count = 0
static func increment() {
count += 1
}
}counter.increment() // count is now 1, this is a static method you can call it without creating an instance of the class.
counter.increment() // count is now 2
