Xcode Playgrounds Can't Access Swift Files in Sources Folder

Xcode playgrounds can't access swift files in Sources folder

You have to add public access attribute to your classes, methods and properties in source folder to make them accessible from main playground file as they treated as separate module by compiler

Can Swift playgrounds see other source files in the same project?

They cannot. Playgrounds are self-contained. This will hopefully change in the future.

Edit: As of Xcode 6.3, Playgrounds can now contain supporting code. They still cannot see other code in the same project, but code can be added to the support folder of a Playground that can be used from within the playground. See the Swift blog for more info.

Sources referencing each other in XCode Playgrounds

Add the public attribute to the classes, methods, and properties that you want to access in other playgrounds. This should solve your problem:

Update:

I found this thread, which although is not on this topic specifically I believe answers the question, here is what the accepted answer says:

So, as I said before, thing is the sources folder can be accessed, but not thing in other playgrounds.

Xcode autocomplete does not work in Sources folder of Swift playgrounds

In order to enable autocompletion, you can embed your Playground in a regular Xcode project (e.g. an iOS application). I recommend creating a dummy project for that purpose. Simply drag and drop your playground in this dummy project and make sure to check "Add to target".

Then you can navigate to

Target -> Build Phases -> Compile Sources -> + -> Add other

and add all the files from your source folder. Please note, that you don't need to actually copy the files, a reference is enough for this purpose.

After this process all your source files are built against this dummy target and you can use autocompletion as usual. As far as I know, this is the best practice for debugging Playgrounds right now. Anyway I am curious, if there is an easier way to achieve that.

How to add a framework to a file in the Sources folder of Xcode Playground?

So I solved this by adding the framework in the "Resources" folder of the Playground. It works now!
