Swift provides good support for object-oriented, and here are a few of its unique features.Lazy Load PropertiesSwift provides support for lazy-loading properties in classes using the language level lazy as a keyword:class Renderer { lazy var loader = Loader() var data = [String]() var render() { // Do something... }}let renderer = Renderer()renderer.data.append("## Hello")renderer.data.append("## Hello A

The Swift class methods are also divided into object methods and class methods, so let's take a quick look at the object methods.We analyze it in three categories.Let's take a look at an example, create a student class Student, he has four attribute names name, age, sex sex, knowledge knowledgeWe define three methods of learning1, without parameters, as long as t

I. Development background Object-oriented method is more and more important in the analysis, design and coding of software development, and it has some advantages that can not be compared with other development methods in adapting to the change of system requirements, improving the reusability of software and developing efficiency.

When we print objects in iOS development, we directly output the object address, which is not convenient for us to develop. When we can use description to print objects, the properties of the output objectYou can rewrite it directly in OC.
