How to join an array of strings into a single string
Swift version: 5.2
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 thanks to the joined() method.
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".
If you called joined() without any parameters it will just stitch the strings together with no separators.
