0x00 Lesson
Inside methods you get a special constant called self
, which points to whatever instance
of the struct is currently being used. This self
value is particularly useful when you create initializers
that have the same parameter names as your property.
For example, if you create a Person
struct with a name
property, then tried to write an initializer that accepted a name parameter, self helps you distinguish
between the property and the parameter - self.name
refers to the property, whereas name
refers to the parameter.
Here’s that in code:
struct Person {
var name: String
init(name: String) {
print("\(name) was born!")
}
self.name = name
}
