An efficient solution doesn’t help if even experienced programmers can’t easily arrive at it. (I’m highly experienced, but I’ll admit I only put in about 5 minutes before I posted that. on the other hand, it shouldn’t take 5 minutes to figure out something that simple with strings. still, maybe i would have done the simple “suffix()” thing had i been looking at the actual swift 4 api’s, but i only had swift 3 api’s in front of me.)
