The Swift Playground You Wanted
Notepad.exe and this website is under construction
. Check out the [FAQ] section for answers to the most common questions.
Notepad.exe is used by thousands of developers from Apple, Facebook, Twitter and others, to run and organise their code.
I really dig the Notes Library and the ability to pin a window to the front. Love the included assist too.
Cot does too little for me, Xcode is overkill for small things so I really love this. The website + the small yellow notes are so cute. We need more whimsical stuff.
Thanks for making this!Jakob |
It's an excellent small code editor to explore all your Swift ideas without launching an heavy IDE like Xcode
And the option to create an image for quickly sharing a piece of code on social networks is just perfect!Thomas Ricouard |
I was really impressed with Marcin squeezing every drop of performance from Sash Zats |
I’ve tried loads of Swift dev tools, and Notepad.exe is one of the few that hasn’t made it onto my naughty list. It’s fast, lightweight and refreshingly low-friction - allowing one to jump straight into experimenting with code snippets without distractions or unnecessary side-quests. It's exactly the Swift playground we've all been wanting.Konstantin |
Notepad.exe is a modern Mac programming companion that I created to help you write better code. It's like having a smart friend who's always ready to help with your coding challenges.
Key features:
- Native macOS app with familiar UI patterns
- Swift-first with intelligent code completion
- Real-time error detection and quick fixes
- Built-in AI assistant that understands Swift context
- Customizable text editing (spaces/tabs, line numbers)
- Clean, distraction-free interface that feels like home
Currently in private beta, I'm crafting Notepad.exe with love and attention to detail. I believe programming tools should be both powerful and delightful to use.
Q: How do I download Notepad.exe?
A: Distribution is by invitation only. Any invited person can invite others. Find someone. You can ask around.
Q: When will you support language X?
A: Sooner than later. We're starting with Swift, though, because we're classy like that.
Q: Can't I just use (insert tool you have an opinion about)?
A: Sure, why not? Go ahead and be a rebel!
Q: (Tool you have an opinion about) does it better.
A: That's fantastic news! More power to you and your tool-wielding skills!
Q: Why?
A: Because I can... and also because unicorns told me so.
Q: Is this Swift Studio?
A: No, but it might transform into one after midnight. Who knows?
Q: Why isn't it open source?
A: For very mysterious reasons, like protecting the last piece of grandma's secret pie recipe. Plus, parts are open source, so we're not total villains!
Q: I could build it over the weekend myself?
A: Go for it! Just make sure to send me a postcard when you're done.
Q: Why don't you just...?
A: Yes! Wait, what was the question again?
Q: It looks like CodeRunner with some AI sprinkled in?
A: Sure, and my toaster's a space shuttle. But hey, great detective work, Sherlock!
Q: Did anyone actually ask these questions?
A: Nope, but it feels good to pretend they did!
