Template for Xcode 8 to create project w/o storyboard, using only code to write the UI.
Xcode 8 template for iOS app with UI completely in code (no storyboards).
Save both .xctemplate directories to ~/Library/Developer/Xcode/Templates/ (you may need to create the Templates directory).
Exit and restart Xcode, File > New > Project, click on iOS group, scroll down to Templates and you should see "No Storyboard"
Create the project, build and run and you should see a completely red view on your device or in the simulator.
