<bikeshed>
It should be isEvenlyDivisible(by:), because 10 is divisible by 3. Just not evenly divisible.

Edited to add:

I'd be in favor of adding isOdd and isEven because:

:one: they increase readability and therefore expressivity

:two: It makes mapping or ternary logic simpler which increases readability and therefore expressivity

view.backgroundColor = row.isEven ? .white : .lightGray

vs

view.backgroundColor = (row % 2 == 0) ? .white : .lightGray // extra parentheses yuck
