- Xcode Proj Template: iOS > App
- Interface - storyboard
- Language - language you wrote the app in (swift or objc)
- Info > Delete 'Application Scene Manifest' and 'Main storyboard file base name'
- Build Phases > add required libraries, frameworks, etc as listed in Theos proj makefile
- Delete -- "Move to Trash" and not "Remove Reference -- all code files (AppDelegate*, SceneDelegate*, and ViewController*, main*), delete Main.storyboard, and copy in your project files from the Theos proj
- Click "+" at bottom of Xcode and "Add Files to 'Proj-Name'"
- Select all the copied files/folders you'd like Xcode to recognize and click "Add" (leave as 'create folder references', no 'create groups', no 'copy items if needed', and 'add to targets "Proj-name"')
- Attempt to build (the "Start" button at the top of Xcode) and fix any include/import discrepancies (Xcode doesn't require relative paths)
Voila!
