Swift Playgrounds on macOS Map Tutorial
Are you looking for …
- informal … but …
- IDE based compiling …
- Swift … code based …
- macOS or iOS … suiting …
… programming environment? How about, if you are into the “where of” in life …
- Xcode on macOS …
- File -> New -> Playground…
- Map
- Next
- Create
Now, by informal, we mean you don’t have to worry about Development or Deployment certificates, and all that jazz. You just get to “play around”, make mistakes, take advice, and learn (more, on top of tutorials like Swift Playgrounds on iPad Primer Tutorial) about Swift programming language, in the process!
We had fun producing a macOS Swift playground desktop application that featured one local “Artwork” class (default) pinning map item, thanks to the great advice from MapKit Tutorial: Getting Started | Kodeco, the new raywenderlich.com … thanks. We ended up with …

Generally speaking around here, we tend to think you need at least a laptop (eg. MacBook Pro) or desktop computer PC (macOS or Windows) or Linux operating system arrangement, to (computer) program (in other words, the iOS operating system is a missing part of the equation here). That has led us to assume more than we know, though looking into this topic via our Google search of …
… had us first looking into Python via “pythonista”, but the $14.99 price tag was far too much for us to absorb so early in the morning, and a warning that exclusive “above the fold” reading can have you suffer from (FOMO) “fear of missing out” syndrome. Reading, then, below the fold, soon turned up the Xcode IDE (we have on macOS, here, and appears “above the fold” regarding blurb actions above) programming language of choice, Swift, with its Apple iPad place …
… as a great resource into programming and “robotics feeling” coding leading to “programming action”! And the presentation may well suit young’uns getting into programming early, if that’s why you are reading this blog posting. As Swift Playgrounds starts out intimating, to “follow a recipe” and perform “steps in order” is likely to lead to the happiest programming and coding experience (to put it mildly … or … just follow orders … initially … to put it more bluntly).
Curiosity is the big key here. Start this way, and invariably if it interests, it interests, and could lead to many other avenues of knowledge, and it involving the Swift computer language, that could be a lead in to iOS mobile app development via Xcode and (paying, or not) careers in Information Technology?!
Or perhaps you are on an iPad and wish to fork out the $14.99 and get into Python, then that would be interesting too, we have no doubt. Either way, see how we R&D‘ed this topic, on an iPad, with today’s PDF presentation (dare we say) following orders.
We’ve also heard, but have not researched this, that Apple is making changes with iPad products into the future, to improve their programming capacities. Stay tuned, with Apple, on that.
