What was your code?

My code works for all cases but it shows test failed in one case,i tried printing array lengths but in that case no log is visible

you can print the arguments

Not a kata issue, your code is wrong. You could have noticed how many guys passed the Swift kata before posting an issue.

Presumably you're mixing up test cases and failed a different input than you're showing here.

My code is failing here:
a1=[2,2,3]
a2=[4,4,9]
"True should be False"

Shoulden't be right?

Your code is trying to iterate over None as the error says.

a or b might be nil or null or None or nothing (except in C++, Elixir, Haskell, PureScript, Pascal, R, Rust, Shell).

Be sure that there is no error in the tests. Print the input to see exactly which test you are failing. For your 2nd example read again the description.

there is a way to see all the tests that have been aplied ?
I m passing just the example.
and I pass if hit test button, I don't get why I am passing the test and not the attempt:

do you get timed out? in that case your algorithm isn't efficient enough, if you fail tests your algorithm is wrong somewhere, try to find out what exactly you did wrong in that case and fix that!

Good eveving every one,

I believe i got the solution, it pass the test, but i got an error anyway.

Could anyone help me ? thanks
