I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.
So below I made a list of leetcode problems that are as close to grokking problems as possible.

| guard oldContentViewBounds.size != .zero else { return } | |
| // Increment of x / y. | |
| let dx = newContentViewBounds.width - oldContentViewBounds.width | |
| let dy = newContentViewBounds.height - oldContentViewBounds.height |
