Initially, my solution had the same problem as yours. But then I went through the sample tests manually, and found my mistake.
I checked your solution, and you do the same mistake as me. Tests seem to be OK, and your solution does not account for one possibility.

I have same problem :)

Hi. It is fixed in the latest version approved. You can:

• Change the function signature to the correct func numbersWithDigitInside(_ x: Int64 , _ d: Int64 ) -> [Int64 ] {
• Or save your code locally, click on reset at the bottom of the page and use the signature from there.

This is necessarily coming from your code, there is no way tests magically multiply all numbers in your result by 10. When you don't know, please: don't raise an issue! See the documentation: https://docs.codewars.com/training/troubleshooting/
