So, I've been researching the realm of custom keyboards and I was about to get started. Then, once I opened Xcode, I naturally looked for the "Custom Keyboard" template under "Application Extension". This template option can be seen in a screen shot in a custom keyboard tutorial by WeLoveSwift (https://www.weheartswift.com/make-custom-keyboard-ios-8-using-swift/). I realize that a question like this (if not exactly) has been asked (Extension project templates not appearing in Xcode 6) here. Sadly, I don't really understand the answer/it doesn't help.
Thanks very much and thanks a load in advance!
