Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I had the same problem, cause is some cases have less than 4 records
I struggled a bit with this kata as Swift is not my primary language, but I was able to solve it without any special crashes or errors (getting the spec right was the other thing though). So if you crash, I think the fault is somewhere in your solution.
Following line in stack trace:
6 libswiftSwiftOnoneSupport.so 0x00007f6e6b488e40 specialized Array.subscript.getter + 124
seems to suggest you perform some out-of-bounds read access on some array, so I would check operations on arrays with unexpectedly small amount of elements (for example, result of splitting an empty string, or something like that).I got the same error. Did you manage to solve this problem?
