"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."
"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!"
"I was really impressed with Marcin squeezing every drop of performance from Electron, only to learn Notepad.exe is a native app. With Marcin's decades of experience building text components this lightweight IDE is great for putting together quick ideas to see what works. Where Xcode playground has to work *despite* Xcode's years of legacy, Notepad.exe has a very promising future ahead of itself"
"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."
Everything you wanted to know about Notepad.exe
A: Download it. You can subscribe to receive information about the release.
A: Sooner than later. I'm starting with Swift, though, because I'm classy like that.
A: Sure, why not? Go ahead and be a rebel!
A: That's fantastic news! More power to you and your tool-wielding skills!
A: Because I can... and also because unicorns told me so.
A: It might transform into one after midnight. Who knows?
A: For very mysterious reasons, like protecting the last piece of grandma's secret pie recipe. Plus, parts are open source, so I'm not a total villain!
A: Go for it! Just make sure to send me a postcard when you're done.
A: Yes! Wait, what was the question again?
A: Sure, and my toaster's a space shuttle. But hey, great detective work, Sherlock!
A: Notepad.exe works with just Swift Toolchain installed, but having the SDK from Xcode allows you to run applications. It's like having both the recipe and the oven!
A: I spent months adding iOS simulators just so you could ask this question. Yes, it runs iOS code now. Your iPhone apps can finally escape Xcode's loving embrace!
A: Nope, but it feels good to pretend they did!
