count a strings length in swift

To count the length of a Swift string, you can use the count property. Here is an example:

main.swift
let myString = "Hello, world!"
let stringLength = myString.count
print(stringLength) // Output: 13
99 chars
4 lines

In the example above, myString is assigned the value of "Hello, world!". The count property is then used to determine the number of characters in the string, and this value is assigned to the stringLength constant. Finally, the length of the string is printed to the console using the print() function.
