Under which circumstance is the index within the range, but the first element is nil?
The function withinRange should take care of that, no?

!list.withinRange(index) || list.first == nil

@qlw319 I still not understand how it came to that state. Is size is bigger than zero, should not the first element exist in that case?

Is it perhaps possible to write a simple test first that causes this issue? That way, we could then understand how it came to be and if we fixed the issue
