get the first 3 characters and last 5 characters in a string then combine into a new string in swift

To get the first 3 characters of a string in Swift, we can use the prefix method. To get the last 5 characters of a string, we can use the suffix method. Then, we can use string concatenation to combine these two substrings into a new string.

Here's an example code snippet:

main.swift
let myString = "Hello World" // example string

let prefix = myString.prefix(3) // "Hel"
let suffix = myString.suffix(5) // "World"

let newString = "\(prefix)\(suffix)" // "HelWorld"
184 chars
7 lines

In this example, we create a new string myString with the value "Hello World". We then use the prefix method with an argument of 3 to get the first 3 characters of the string, which is "Hel". We do the same with the suffix method and get the last 5 characters of the string, which is "World". Finally, we use string interpolation to combine the two substrings into a new string, which results in "HelWorld".
