String in swift is a collection of characters. To find the length of a string, swift string comes with a count property. Read the count and you will get the total character count.
Let’s take a look at the below example :
let string1 = "a" let string2 = "a b" let string3 = "" let string4 = "!!" print(string1.count) print(string2.count) print(string3.count) print(string4.count)
It will print the below output :
1 3 0 2
