How to get the Type of Variable in Swift?

Swift – Get Type of Variable

To get type of a variable in Swift, call type(of:) function, and pass the variable as argument for of: parameter.

Example

In the following example, we will initialise a variable with the value 3.28, and programmatically get the type of this variable.

main.swift

import Foundation

var x = 3.28
print(type(of: x))

Output

Double

Now, let us initialize the variable with “Hello World”, and get the type of this variable. We know that this variable is of type String. Let us check that programmatically.

main.swift

import Foundation

var x = "Hello World"
print(type(of: x))

Output

String

Similarly, we can get type of any variable using type(of:) function.

Conclusion

In this Swift Tutorial, we learned how to get the type of a variable in Swift using type(of:) function, with the help of example.
