What are initializer in Swift?

Swift initializer is a special type of method that can be called to create a new instance of a particular type.

Swift provides a default initializer for any structure or class that provides default values for all of its non-optional properties and does not provide the initializer itself.

Swift initializer Example

class User {
    var first_name: String
    var last_name: String
    
    init(first_name: String, last_name: String) {
        self.first_name = first_name
        self.last_name = last_name
    }
}
let p = Person(first_name:"Santosh", last_name:"Botre")
