Project 10. Names to Faces.

Concepts

  • Collection Views.
  • UICollectionViewController
  • UIImagePickerController
  • Data
  • UUID
  • CALayer
  • UIAlertController
  • More on closures.
  • UUID (Universally Unique Identifier)
  • Filemanager.default.urls(for:in:)

Notes

Collections Views are extremely similar to Table Views, with the exception that they display as grids rather than as simple rows.

All apps that are installed have a directory called Documents where you can save private information for the app, and it's also automatically synchronized with iCloud.

FileManager.default.urls(for: .documentDirectory, in: .userDomainMask) asks for the documents directory, and its second parameter adds that we want the path to be relative to the user's home directory. It returns an array.
