Suppose I have an array of var code = [25, 17, 46, 23, 55] and I need to derive data from it.
You can do this with
for var i = code.count; i<0; i-=1 {print ("\(code[i])")} for var i = code.count; i<0; i-=1 {print ("\(code[i])")} but xcode says that the c ++ style will be deleted soon and does not even output the result to me.
Do I have an error in the code, and if not, how else can I output the data in the reverse order?

    In your example code, two errors:

     for var i = code.count-1; i>=0; i-=1 {print ("\(code[i])")}

    You can rewrite it as follows:

     for i in (0...code.count-1).reverse() { print ("\(code[i])") }
