Validate string against common formats:

"[email protected]".isEmail // true
"123456789".isNumber // true
"zamzam".isAlpha // true
"zamzam123".isAlphaNumeric // true

Remove spaces or new lines from both ends:

" Abcdef123456 \n\r  ".trimmed // "Abcdef123456"

Truncate to a given number of characters:

"Abcdef123456".truncated(3) // "Abc..."
"Abcdef123456".truncated(6, trailing: "***") // "Abcdef***"

Determine if a given value is contained:

"1234567890".contains("567") // true
"abc123xyz".contains("ghi") // false

Injects a separator every nth characters:

"1234567890".separated(every: 2, with: "-") // "12-34-56-78-90"

Remove the characters contained in a given set:

let string = """

Replace the characters contained in a given character set with another string:
