How to get Length of String in Swift ?

To get the length of a given string in Swift, you can use the count property of the String class.

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use the count property of the string object str1 to get the length of the string and store the returned value in the variable length1.
The count property returns the length of this string.
Finally, we print the value in length1 to the console using print().

// Length of "Hello World" String
let str1 = "Hello World"
let length1 = str1.count
print("Length of given string is: \(length1)")

Length of given string is: 11

In this example,

We create a variable named str2 with a string value of "apple".
We then use the count property of the string object str2 to get the length of the string and store the returned value in the variable length2.
The count property returns the length of this string.
Finally, we print the value in length2 to the console using print().

// Length of "apple" String
let str2 = "apple"
let length2 = str2.count
print("Length of given string is: \(length2)")

Length of given string is: 5
