Introducing ClassKit

WWDC 2018

Apple School Manager

• Create managed Apple IDs
• Create rosters
• Manage content and devices
• Opt in for progress reporting
• Purchase apps in bulk

Schoolwork

• A new education app for students and teachers
• View assigned handouts
• Create new handouts
• View progress reports

LifeCycle of a Handout

• Content is represented via CLSContext
• One main app context (root context)
• App content is added to the app context
• Define content as early as possible

Developer Mode

• Settings > Developer > ClassKit API

Framework Classes

CLSDataStore

• Maintains the context tree
• Exposes the mainAppContext as a property
• Keeps track of modified objects
  - Objects saved by calling CLSDataStore.save(completion: )
• One shared instance

CLSContext

Context Identity

• identifier property
• Context identifier Path
  - Identifies a context within a context tree
  - Array of context identifiers

Context Identifier Path

Context Lookup

CLSDataStore Delegate

• Works in conjunction with path query methods
• Used to create missing contexts on demand
• Useful for apps with dynamic content

CLSActivity

• Always associated with contexts
• Created by calling CLSContext.createNewActivity() → CLSActivity
• Access current using CLSContext.currentActivity: CLSActivity?
• Creating a new activity is akin to a new attempt

CLSActivityItem

• Abstract class with three subclasses
• Always set the same subclass for primary activity items
• Provide clear and concise titles
• Make use of additional activity items

Steps for Adopting ClassKit

• Define CLSContext structure
• Add CLSActivity and CLSActivityItems
• Support deep linking
• Test with Developer Mode and Schoolwork

Defining CLSContext Tree

CLSContext

• Use clear titles !!!
• Define contexts early
• Take advantage of displayOrder
