Merge array elements with "\n" into String in Swift

Question

I'm trying to merge array of string with \n, but didn't get any solution. I have following types of array which contains section names.

let arrSectionName = [
    "Section 1",
    "Section 2",
    "Section 3",
    "Section 4",
    "Section 5",
    "Section 6",
]

Now, I want this string from above array:

"Section 1 \nSection 2 \nSection 3 \nSection 4 \nSection 5 \nSection 6"

So Finally message should display as follow:

Alert Message Output:

    Following section which are still pending to complete, please verify and try again:
    Section 1
    Section 2
    Section 3
    Section 4
    Section 5
    Section 6

Section name are dynamic, which will be change runtime and store in arrSectionName.

You should use joined(separator:). It joins the array elements and adds the given separator string between the elements.

let str = arrSectionName.joined(separator: " \n")
