How can I set a string variable and make it always lowercase?

Question

I want to set a string variable and want to keep it always lowercase.

This is my code :

var alwaysLowercaseString : String? {

    didSet{
        alwaysLowercaseString = alwaysLowerCaseString!.lowercaseString
    }
}

But when I use it, it goes into a infinite loop. How can I solve this problem?

I stand corrected, this is the correct approach. LeoDabus deserves the credit for this answer:

var alwaysLowercaseString : String? {
    
    didSet{
   
    alwaysLowercaseString = alwaysLowercaseString?.lowercaseString
      print(alwaysLowercaseString)
    }
}
