Return Value

It returns a random character from the string.

Example

// create string values
let name = "Theodore"
let language = "Swift"
let role = "Software Developer"
// get random characters from 
// strings and print results
print(name.randomElement()!)
print(language.randomElement()!)
print(role.randomElement()!);
