how can I join words from a String array to a single String, separated by a comma in Swift? [duplicate]

Question

I have an array of Strings in my Swift app. I want to display them in a label, each of them separated by ,. I tried this:

for hashtag in placeHashtags {
        text = text + "\(hashtag), "
    }

if (placeHashtags.count > 0){
    let text1 = text.remove(at: text.index(before: text.endIndex-1))
    text = text1.description
}

(the 2nd if is to remove the last comma), but then I do not see anything in my label. How can I fix it?

The actual problem in your code is that text.remove(at:) returns the removed character, not the modified string. — Martin R

You should Write this:

let array = ["Hi", "Hello", "How", "Are", "You", "Fine"]
let joined = array.joined(separator: ", ")
