Both the Google Classroom and discussions board are just a way to make the students feel a little more connected to the material and to each other. It helps to have support, especially when you’re learning something new!
Today we’ll touch on what we did last week, briefly, and then we’ll get into the meat of for loops!
Links
Bill Chapman, of the University of Illinois dropped a nice note with links to his own video resources. So if you want to check them out while you’re going through the Learn to Code Swift Playgrounds you might find them helpful. They’re well worth checking out, because the more time you spend with these playgrounds, the more practice you get, and the better programmer you become!
Day two we continued with the Commands chapter of the Everyone Can Code book and reviewed some of the puzzles we’d solved the previous day.
On day three we jumped into Functions, the next chapter in the book, and talked through the coding concept of functions.
And today, Friday, day four, we started with some advice about how to follow along with the live sessions or the videos and code on your iPad. We then jumped back into the Functions chapter.
Homework
“What? Homework? We’re all stuck at home all the time already?” you might be saying.
Well, consider it weekend work, then. Programming requires practice, just like playing a musical instrument or a sport; you don’t get better if you don’t try out the skills you’ve learned.
At the end of today’s video, we set you a challenge: solve the Treasure Hunt puzzle in the Learn to Code 1 playground.
Use functions, do it all out longhand, see how you get on. You can capture a PDF of your code from the ...‘s menu in Swift Playgrounds or you can copy and paste it into a thread on our new forum.
I won’t say there are no wrong answers, but even if your answers don’t 100% solve the puzzle, at the very least you’ve made an effort. Even the best of us programmers have bugs in our code!
Coming Up Next Week
Next week we’ll have more content and walk throughs of the Learn to Code 1 playground. We’ll also review the homework and show off one potential solution, at least.
I’m hoping to re-record some of the intro videos, for those of you coming to the sessions late, or who just want a refresher.
For today’s session we’re going to show you a good setup for following along with our live stream or videos and coding at the same time. We’ll also recap a little bit about functions.
The beginning of the video will help you get set up, so long as you have an iPad and an internet connection.
If you prefer to read your instructions, yesterday’s post will show you where to go to get Swift Playgrounds and Everyone Can Code Puzzles, the ebook we’re using.
Today’s Session @ 1pm Irish time
For today’s session we’re going to walk through some more lessons about commands: how to use them, how to figure out when they’re not doing what we expected, or debugging. We’ll look at strategies for solving puzzles, which is a lot of what programming is.
So tune in, grab your iPad, and spend a little time with me, coding!
In Part One of this special Coding at Home series we looked at our new app: Learning Variables.
In Part Two we looked at the Swift Playgrounds we’ve developed at The Code Hub and how to get them on your Mac or iPad.
For Part Three we checked out one of my favorite playgrounds, Text Adventure.
Code with Me
Now we’re going to try a slightly different tack.
Starting this week we’re going to hold live coding sessions to teach you about coding.
Since I use iPads in my class, I’ll be taking advantage of those devices for the course. They don’t necessarily have to be spring chickens, either, so long as you can install Swift Playgrounds.
Swift Playgrounds is available on the App Store for free. Just have a search for “swift playgrounds” and tap on the GET button.
And that’s it, that’s all you’ll need for the first few lessons.
If you’re following along at home, and all of you should be (at home, that is), we’re going to start with material from Apple’s excellent Everyone Can Code curriculum.
We’ll be working from the student guide, but if you’re a parent (or a kid teaching another kid, your parent, or your pets), the teacher guide gives some great suggestions about how to teach coding, with varying levels of difficulty.
So hopefully I’ll see you at 1pm, Irish time, today.

Text Adventure!
For part three, we’re going to look at the Text Adventure playground we’ve developed, in particular. This is one of my personal favorites, because it reminds me of my own start in programming; BASIC, The Hitchhiker’s Guide to the Galaxy interactive fiction, and MOOs.
The playground is designed to take advantage of a little library I wrote that models a story with a number of rooms, through which your protagonist navigates. The goal is to use coding to be a little bit creative and get the kids (and adults) telling stories and using code as a means to and end, rather than the end, itself.
Getting the Playground
To start, go grab the playground from the Code Hub’s Playgrounds feed (explained in Part Two). You’ll see the Text Adventure playground front and center now:
More Playgrounds: Getting the Text Adventure playground
Telling Stories
Once you have that in Playgrounds, you can open it and you’ll see the introduction to the whole shebang.
Pretty self-explanatory so far, right?
We don’t have to write any code at all, just hit the “Run My Code” button and off we go!
I won’t post any spoilers here, but the stories are gripping, edge-of-your-seat kind of stuff.
Once you’ve exhausted all the possibilities in the first story (and that might happen pretty quick), you can hit the Next button to move on.
The playground is designed to dip you into coding your own story gently and follows a progression that looks like this:
You can skip around if you like, of course, but I try to introduce concepts that will introduce you to code and the features of the Story library as we go. So try it out. If you come up with a particularly cool twist or story of your own, use the built-in tools to record your story.
From the three dots in the menu, select Record Movie to start capturing your story.
Full Screen
One last tip, the stories work best in fullscreen mode. You can enter fullscreen by tapping on the divider between your code and the story view.
Drag to the left, and the story view will take up the full screen. To get out of full screen you’ll just tap on the left side of the screen (you might see the faint arrow on that edge).
In Part One, we looked at a relatively painless way to talk about and experience variables.
Swift Playgrounds from The Code Hub
One of the other little tweaks we’ve just shipped is an update to our Text Adventure Playground. But let’s start with a little (re)introduction of Playgrounds, for the uninitiated.
If you didn’t already know, The Code Hub has a suite of Swift Playgrounds for use in the iPad (and now Mac!) Playgrounds app. When you download Playgrounds, which is a free download, you’ll see a bar along the bottom of the screen with the headline “More Playgrounds.”
More Playgrounds!
Apple provides an excellent array of playgrounds authored to teach you how to code, to learn augmented reality development. Or some innovative uses of content and code like the Cipher playground. The app is free, as are playgrounds you can download from Apple and third parties (like The Code Hub).
But if you are on an iPad and go to https://thecodehub.ie/playgrounds/ you can click on the Subscribe button to add The Code Hub’s suite of playgrounds to the app. Alternatively, on the Mac version of Playgrounds you can scroll to the bottom of the additional playgrounds and you’ll see the option to enter a subscription URL:
Enter in www.thecodehub.ie/playgrounds/feed.json and you’ll be good to go. You’ll see a confirmation dialog like this:
And, once you hit Subscribe, you’ll see a list of our playgrounds.
Right now, the 18th of March, 2020, we have six. I’ll try and touch on each of them in the next few weeks. But for now, you can download any of them onto your device and play around with them. There is a bit of explanatory text for each of the playgrounds, so you won’t be left completely at sea.
It helps to have a bit of Swift knowledge, but that, too, I’ll be touching on in the coming weeks.
Well, it’s been a long time, but we’re still here, and in fact, we come bearing news.
While we’ve been stuck, pottering around the house, we improved a couple of our learning resources so that you, too, can use these to exercise your coding muscles!
Learning Variables
The first is our app, Learning Variables. We’ve long been using this app in our classrooms to help teach the concept of variables, but now we’ve released it for iPads, iPhones, and the Mac (thanks to Catalyst!).
There are a few built-in stories to start you off. Pick a story, and you’ll see a list of variables to fill in with some hints about what kind of value we’re looking for:
Enter in a few words according to the hint, and you’ll wind up with something like this:
It’s a little goofy exercise that will show students how variables can be used. They can go back and change what they entered and watch the story change. Or they can write their own story. We’ll rip out a few key words and create variables for students to fill in and re-generate their story with their new variable values in place. It’s handiest to have the kids write their own stories and then hand the devices around the classroom (or home) and see what their classmates (or siblings, parents, pets*) do to their stories… but I’d love to hear how you use it in your classroom (or home)!
If you have any requests or bugs, feel free to drop us a line at [email protected] and we’ll see what we can do.
* Please note, pets are terrible at coming up with values for these variables.
