swift-playground | modify Xcode Swift Playgrounds from Ruby | Awesome List library

I am making an PlaygroundBook for Swift Playgrounds [Not Xcode Playgrounds]. I want pass data between playground pages. Example, I have an public variable in UserModule and its value is 0. In first page, user change this variable to 1. When user go to second page, variable's value is 0. But I want its value is user's value (1). How can I do that?

I'm using SwiftUI. I tried to use UserDefaults but UserDefaults won't work truly in Swift Playgrounds. And also try to save datas to a JSON file but Playground won't write files (only read). I also tried this but it isn't work too.

I'm new to swift and would like to learn its integration with Python. I saw fast ai course on swift and they use Python libs from it. My question is related to this post where I want to run simple example like this one:

I tried the following codes in a playground file.

I would like to debug a method deep inside my "Sources" folder within a Swift Playground.

I want to perform an edit, a JEPG compression for example, on an image from the gallery (taken by iPhone camera) but it fails when the input image is an HEIC image but works with JPEG images.

I retrieve the image within a PHAsset object via UIImagePickerController method:

AudioKit has had playgrounds since they were introduced, and we made hundreds of them, but as of about Xcode 8, they have become difficult to use. After about 4-5 playground views on average, Xcode will stop running any playgrounds and need to be restarted.

Here are the AudioKit's playground code: https://github.com/AudioKit/AudioKit/tree/master/Playgrounds

as well as screen recordings of how they should work: http://audiokit.io/playgrounds/

We basically use the set up as described in this blog to use the AudioKit framework in playgrounds: https://m.pardel.net/using-3rd-party-frameworks-in-swift-playgrounds-fd415f6dba10

The playgrounds are equally unstable if we use playgrounds on the Xcodeproj itself as if we are using the framework file.

Does anybody have any clue as to what happened to make Xcode playgrounds unstable with frameworks or have any advice on how we could change our set up to make the playgrounds stable again?

AudioKit playgrounds were a major part of what makes AudioKit easy to use and the loss of them has weighed heavily on me, so I am happy to offer a bounty (my first one, so bear with me).

In the last update notes for the Swift Playground app for the iPad I saw that the cameras would be accessible through the playgrounds. For testing purpose I've therefore created a playground to access my iPads back camera. As reference I've used those sources:

• https://github.com/francip/swift-playground-camera/blob/master/Camera.playground/Contents.swift

Here is my code:

I'm new to Swift, now I just want to translate java xor encrypt/decrypt code to Swift, which is used for transactions between server and client. Below is the Java xor code:

I was doing some exercises on Xcode 9 beta 2 Swift 4 from this article (https://www.uraimo.com/2016/01/06/10-Swift-One-Liners-To-Impress-Your-Friends/) when I came across an error while doing item no. 6:
