Loop through an array of strings

Does someone know how you can loop through an array of strings, and set each string to an empty string?

In my app have created 3 variables that stores a string each. I have then appended those 3 variables to an array, and tried this method: for string in strings { string = "" } I get an error saying string is a constant. I then change my code to for var string in strings... The error goes away, but it does´t work

for index in 0..<strings.count {
    array[index] = ""
}

When you made the loop for string in strings the 'string' value is actually a copy of the element in the array. When you set string="", you were only changing the value of a copy you had made.

To change the actual value of the element in the array, instead of just making a copy, you have to use strings[indexNumber] = "" instead.
