should help you out I want to declare all of them null. Am I doing someting wrong or is this the right method? , Yep. That's the way to do it.
You could also do
code :
String a, b, c, d;
a = b = c = d = null;
String a = b = c = d = null;  // illegal

To fix the issue you can do There is a way, using eval, but you would rather not want to use it (and I would even go that far to say that it might be better not to learn it until well later).
There is simply no case when you would use that instead of plain arrays.
code :
(0..3).map{|i| i * 2}
#=> [0, 2, 4, 6]

Hope that helps Don't try to use dynamically named variables. That's simply not how variables work in C#.
Use an array of lists:
code :
List<string>[] user = new List<string>[infoForUserSessions.Count];

for (int i = 0; i < infoForUserSessions.Count; i++) {
  user[i] = new List<string>();
}

hop of those help? You cannot create dynamically named variables in C# (and I am with those who are wondering why you want to do that). If you don't want to use an array, consider a Dictionary -- it would perform better than an array in some circumstances.
code :
Dictionary<string, int> values = new Dictionary<string, int>();
for (int i = 1; i <= 4; i++)
{
    values.Add("value" + i, 0);
}

value["value1"]; //retrieve from dictionary

fixed the issue. Will look into that further I have a function that returns a tuple of 3 UIImages.
code :
func getImagesTuple(from array: Array<String>) -> (UIImage, UIImage, UIImage) {
  (UIImage(named: array[0])!, UIImage(named: array[1])!, UIImage(named: array[2])!)
}

let (imageOne, imageTwo, imageThree) = getImagesTuple(from: ["imageOne", "imageTwo", "imageThree"])
