What is the hasSuffix() method in Swift?

Overview

The hasSuffix() method lets us check if a string ends with a specified string. If it is true, then true is returned. Otherwise, false is returned.

Syntax

The syntax of the hasSuffix() method is given below:

str.hasSuffix(suffix)

Parameters

suffix: This is a string, and hasSuffix() checks whether or not the str string ends with the suffix string.

Return value

The value returned is a Boolean that is true or false.

Code example

// create strings 
let str1 = "Edpresso is the best"
let str2 = "Best place to be"
let str3 = "Learn all you need"
// check the suffixes below
print(str1.hasSuffix("Edpresso"))
print(str2.hasSuffix("be"))
print(str3.hasSuffix("need"))

Explanation

  • Line 2-4: We create some strings.

  • Line 7-9: We check if the strings end with specific suffixes. Then we print the results.

  • Line 7: This statement returns false because str1 does not end with “Edpresso”.

  • Line 8: This statement returns true because str2 ends with “be”.

  • Line 9: This statement returns true because str3 ends with “need”.
