If you have an array of strings and want to merge all the elements together into a single string, it's just one line of code in Swift.
For example, this joins array elements with a comma:
let array = ["Andrew", "Ben", "John", "Paul", "Peter", "Laura"] let joined = array.joined(separator: ", ")
The result is that
joined is set to "Andrew, Ben, John, Paul, Peter, Laura".
