Just building on what @KnightOfDragon said, I would just create a subclass of SKSpriteNode for each key. That way it keeps your code objectified and pretty!
There is so much more that can be done here, but I whipped this up in a hurry. It doesn't have all the letters and it doesn't know how to handle del, space, return, but I figured your code already knew what to do with those.
The Key class uses a protocol to send down which key was pushed, so you don't have to worry about capturing each key area in the scene
So I entered the rest of the keys and added some blank filler options for spacing. I don't have the same font as you but it looks pretty cool
