Split a String into an array in Swift?

A new function split in Swift 4

import Foundation
let sayHello = "Hello Swift ! 2019";
let result = sayHello.split(separator: " ")
print(result)

Output:

["Hello", "Swift", "!", "2019"]

Accessing values:

print(result[0]) // Hello
print(result[1]) // Swift
print(result[2]) // !
print(result[3]) // 2019

Xcode 8.1 / Swift 3.0.1

Here is the way multiple delimiters with array.

import Foundation
let mathString: String = "12-37*2/5"
let numbers = mathString.components(separatedBy: ["-", "*", "/"])
print(numbers)

Output:

["12", "37", "2", "5"]
