Swift Properties and Get/Set Usage

The Swift programming language has become one of the indispensable tools of modern application development. Especially "Swift properties" and the "get/set" keywords provide great convenience in encapsulation and data integrity in object-oriented programming. In this article, you can find fundamental information on what "Swift properties" are, how they are defined, and how to use them with get/set.

What are Swift Properties?

In Swift, the term "property" expresses a characteristic or data of a class, struct, or enum. Properties are basically divided into two: stored and computed properties. A stored property saves a value directly, while a computed property determines the value dynamically with get and set functions.

Defining Property with Get/Set

The get and set keywords allow you to define customized behaviors for "Swift properties". Especially computed properties are often used with get and set blocks. Below is a basic example:

struct Dikdortgen {
    var en: Double
    var boy: Double
    var alan: Double {
        get {
            return en * boy
        }
        set(yeniAlan) {
            en = sqrt(yeniAlan * boy / en)
        }
    }
}

var d = Dikdortgen(en: 5, boy: 3)
print(d.alan) // 15.0

In this example, "alan" is a computed property and calculates the current value on each access. Moreover, with the set block, when a new value is assigned from outside, the desired behaviors can be performed.

Customization on Properties

With get and set, you can define validation, transformation or different logics on property values. This increases the readability and maintainability of your code through the use of "Swift properties and get/set".

Conclusion and Best Practices

The "Swift properties and get/set" mechanism makes your code safer and more understandable. Especially in terms of data encapsulation and property management, it offers a powerful structure. By customizing property usage in your applications with get/set functions, you can increase data integrity and keep your code more flexible.
