Get Class Name of an Object as String in Swift

This article will explain to you how to get the name of the class of an object in the Swift language.

Swift provides us with a function called type(of:) to get the type of a value or the class name of an object.

You can use the type(of:) function to find the dynamic type of a value, particularly when the dynamic type is different from the static type. The static type of a value is the known, compile-time type of the value. The dynamic type of a value is the value's actual type at run-time, which can be a subtype of its concrete type.

Example

import Foundation
class Person {
    var name: String?
    var address: String?
}
class Student: Person {
    var rollNumber: Int?
    var schoolName: String?
}
let personObject = Person()
let studentObject = Student()
let className1 = String(describing: type(of: personObject))
let className2 = String(describing: type(of: studentObject))
print("personObject type: \(className1)")
print("studentObject type: \(className2)")

Output

personObject type: Person
studentObject type: Student

Explanation

In the above example, we used the String(describing:) function to get the type in string format.

Conclusion

The type(of:) function is used to get the class name of an object. This function works with any type of object like Int, String, custom objects, etc. You can use the String(describing:) function to convert the object type into string format.
