It seems on every refresh of the page, the same resources are downloaded over and over again. It would be more efficient to have caching on the client side, hence less CO₂ emission.

Any ideas to support the ⌘ + ENTER keystroke combination to run the code in the playground? Essentially, this key combination would do whatever happens when the green Run button is clicked. That would be cool!

It would be great to interact with playground for multiple users simultaneously like https://code.yandex-team.ru/

HTTPS link in the description does not work: https://SwiftPlayground.run → http://SwiftPlayground.run.

1. Open http://online.swiftplayground.run/
2. Click Sign out
3. Try to use the link with ?sourceURL= (or just use an incognito session for the link)

Expected:
Playground with code.

Actual:
Page with Let's play button.

Hi

the first.... great tool, I use it every time when i need something to check in swift. But now for long time web http://online.swiftplayground.run/ is not working

Can you please look at it

Thanks :)

Sometimes scrolling within the code window and output window does not work properly.

This is a screenrecording of the issue in the output window, couldn't replicate again the code window issue.

Using Chrome Version 81.0.4044.129 (Official Build) (64-bit) on MacOS.
Code wrote in the Code Window to reproduce the issue in the Output Window:

import Foundation

class Adapter: NSObject {
    static var lat: Int = {
        // some calculations
        print("lat")
        return 1
    }()
}

print(Adapter.lat)
print(Adapter.lat)

class Adapter2: NSObject {
    static var width: Int {
        // some calculations
        print("width")
        return 1
    }
}

print(Adapter2.width)
print(Adapter2.width)

I tried to build and run locally. The UI came up fine and the backend started fine as well. I'm running on macOS Catalina, Xcode 11.1. However, when the call eventually lands up at the backend, what I get back in the UI is error: no such module 'OnlinePlayground'. Please see screenshot. Could you please help to shed some light and help me debug this?

I've noticed the server stop responding after some time (usually ~2 days) and can't properly restart it. Not sure what the NIO is doing but I have to reboot (or logout) the user to unbind. It's weird. Does it ring any bell @josefdolezal?

Launched as

.build/swift-5.7-RELEASE/x86_64-apple-macosx/release/PlaygroundServer serve --hostname 0.0.0.0

It may, or may not be related to vapor/vapor#2502

My issue is i wanna see the compile time, like how many ms it takes to compile. how can i do that. Appreciate.

If you include "assert()" in the source code they don't seem to be evaluated. To reproduce the error just try assert(false). Nothing happens when executing.

The idea comes from typescript playground. If you open up the following
https://www.typescriptlang.org/play/index.html#src=console.log(%22Hello%22)%3B , you'll see that the source is console.log("Hello"); which was embedded in hash as #src=conso..... So, you get point.

This way it would be really easy to share some runnable snippets to online.swiftplayground.run. Including the swift version as well it would be something like this:
http://online.swiftplayground.run/#v=4.2&src=print(%22Hello%22)

A bit related to #5

Trying a code snippet that doesn't import anything doesn't work for me on http://online.swiftplayground.run/. When trying just print("lol"), the output is the following:

Hi

Thank you for great web. I am using it to check my code, and quick scripts

But can be possible to upgrade versions of swift on the web interface? You are providing only 5.0 and 5.1-release of swift, but today is out version 5.5.2 (https://github.com/apple/swift/releases)

It may be handy in some situations

Thank you for considering it.

Can't connect to server http://online.swiftplayground.run

Now the editor is resizing/scaling correctly on smaller devices. This should be fixed
