I'm on my first iOS developer interview this week, and to practice I went to HackerRank which was recommended to me by a friend. It's a pretty neat site, but for my love I can't get the most basic questions on that site right.
On the site, you are allowed to lose a question and see other people's answers, and I have noticed that almost every answer uses readLine (). I've been searching for a while and I can't understand what this means, nor have I ever seen it in any Swift code before.
I've seen pretty much every YouTube video on iOS developer interviews from Let's Build That App and Sean Allen and it seems simple. I have no problem grasping ideas like binary search or two-sum problem, but HackerRank is on another level.
Edit: Also worth noting that almost all Glassdoor reviews for iOS interview questions are about how simple the questions are (Merge Sort, wrapping arrays, etc.)
