Avoid Playgrounds, for Swift LeetCode Challenges

Use the macOS Command Line Tool template

Taking an example project from LeetCode, I might try to find the answer for 1413. Minimum Value to Get Positive Step by Step Sum.

Now I told a lie, in one of these articles. Specifically in my Playgrounds article I said I don’t use Playgrounds for LeetCode challenges because of the setup. I actually don’t use Playgrounds because sometimes they are slooow, or don’t seem to work for me when I first start a new Playground. I don’t know why, perhaps it’s because I’m using a 2016 MBP? In any case, I really use the macOS Command Line Tool, and set this up with testing.

This article is about how you might do the same.

The problem

Initially the problem is quite confusing.

The description is, to be honest, not that great. So here is my interpretation:

Given an array of Interges called num traverse the array from left-to right keeping a running total. Find an initial number such that the running totol is never less than 1.
