Display an array of string in custom format

Question

I have an array of name like this

let arrayOfName = ["alex","lonzo","lavar"]

and sometimes my array only has 1 element but it will never be empty

let arrayOfName = ["lavar"]

is there a way that I can display all the names in this string format? For example in the 1st case:

"studentName=alex&studentName=lonzo&studentName=lavar"

and for the 2nd case, it would be

"studentName=lavar"

Thank you very much for your help!

FYI - If you are doing this to build a URL with a query string then please look into URLComponents and URLQueryItem. — rmaddy

Use a map and joined:

let arrayOfName = ["alex","lonzo","lavar"]
let namesResult = arrayOfName.map { "studentName=\($0)" }.joined(separator: "&")
print(namesResult)

Result:

studentName=alex&studentName=lonzo&studentName=lavar

This will work even if the array has zero or one name or any number of names.
