added single view application and SpriteKit game template

[Wh0ba]

Added a template for a single view application which contains a simple UIViewController with a white background And a SpriteKit template for making games using theos (I've made some games using it ) contains two scnes one for the menu and one for the game

The are both to easy to understand and work with

Hopefully this helps people who want to make apps but doesn't have XCode to do so I've made a full functionality apps using these templates

Hi, what happened to this pull request, will it ever be merged? I say this cause because these look like some good templates. Thank you

The overall code formatting looks off. Check the other templates so that lots of unnecessary empty lines can be removed and the indentation can be consistent.

Is there still a use case for a SpriteKit game template? If so, we can likely go ahead with editing this in-place as the requested changes don't appear to have been addressed. Also, it seems that the application template pr'd is extremely similar to the one introduced in https://github.com/theos/templates/commit/12a565ab99d4132a2f0f0702ecffffbdd063c1c2 except that is presents a UIView instead of a UITableView. Given this, I'm in favor of removing that portion for the pr.
