i'm new to swift programming and was hoping to utilize a conditional && for a while loop but it almost seems like i need to break it out and have a nested while loop?

what i'm trying to do:

------------------

counter1 = 0

counter2 = 0

while (counter1<0) && (counter2<0)

-----------------

that way i can use common code, otherwise it seems like i need to have 2 nested while loops and possibly duplicate code for each loop?

Thanks

It does work !

What error do you get ?

You need to write :

while (counter1<0) && (counter2<0) {

Didn't you forget the open bracket after while ?

With the initial conditions you set (both counters = 0), you will not execute anything inside the loop.

If you want to execute at least once, use repeat while :

repeat {
    print("I did it once at least", counter1, counter2)
     counter1 += 1
     counter2 += 2
} while (counter1<0) && (counter2<0)

It would help if you:

Posted a slightly larger snippet of code, because it’s very hard to tell what you’re trying to do from the code you did post
Put your code in code block (using the
```
<>
```
button in the editor), because that makes it easier to read and easier to reference by line number
