I want to delete 5 characters in a string, so I plan to use a loop to do that. but actually code not report any error, but still, I can only delete one character

var i = Int()
repeat {
    proxy.deleteBackward(); 
    i = i+1
} while i<5

if you want to remove last 5 characters of your string , use

myString.dropLast(5)

if you want to run your deleteBackward() method 5 times, use like this

var i = 0
        while i<5 {
            proxy.deleteBackward()
           i += 1
        }
