Xcode Autocomplete Does Not Work in Sources Folder of Swift 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.

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

Deleting the DERIVED DATA folder seemed to fix my issue. Thanks to this post: swift println() not showing autocomplete options while writting code

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:

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.

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

Can't visualize UIBezierPath in Playground

I would say this is a bug in Xcode 8.3. It gave me the same result in Xcode 8.3. I just tried your code in Xcode 8.2.1 and it draws a line in the quick look window.

This is something that should be filed as a bug report to Apple.

In the meantime, either use an older version of Xcode, or embed the bezier path in a view and quick look the view.
