• To apply existing programming skills to the mobile domain, addressing challenges such as memory restrictions, touch-based interfaces, and rapidly evolving architectures.
• To appreciate the wide range of tools and platforms available for mobile development, and be able to identify appropriate tools for various tasks.
• To be proficient with the XCode development environment and the Swift programming language.
• To design and implement apps that address real-world needs, using best practices in design and software engineering.

Mobile landscape
  mobile vs. desktop applications
  native vs. Web-based development
    Progressive Web Apps (PWAs)
    other hybrid technologies: WebAssembly, Houdini
  iOS vs. Android
    market share, ease of development, profits vs. volume
    iOS history
    iOS architecture: Cocoa Touch, media layer, core services, core OS
  mobile design guidelines
    iOS design themes: clarity, deference, depth
    iOS design principles
      aesthetic integrity, direct manipulation, metaphors,
      consistency, feedback, user control

Swift
  language basics
    variables: let vs. var, scope
    data types: type inferencing, expressions, Strings, enumerations   
      optionals: ?, !, if-let
    control statements: if, while, for (with ranges), guard
    functions: internal vs. external names, default parameters
  collections 
    array: e.g., names : [String]
      field: count; methods: append, +=, remove, insert
    dictionary (map): e.g., var ages : [String:Int]
      fields: count, keys, values; methods: contains, remove, filter
  user-defined types
    struct: generally used for data structures
      value type, must specify mutating methods, no inheritance
      (note: arrays & dictionaries are structs)
    class: generally used for full-blown objects
      reference type, supports inheritance (must specify when override)
  OO design
    protocols: CustomStringConvertible, Equatable, Comparable, user-defined
    computed properties/fields
    Model-View-Controller (MVC) pattern
  data persistence:
    reading text from a file, Bundle.main.path
      parsing the text using String.split and String.components
    reading writing objects into plists
      Codable protocol, PropertyListEncoder/PropertyListDecoder
      encoding & writing, reading & decoding

Xcode/UIKit
  Xcode IDE
    playgrounds vs. projects
    IDE areas: editor, toolbar, navigator, debug, utility
    Single View App template: ViewController.swift, Main.storyboard
  iOS UIKit
    UIView subclasses: UILabel, UIImageView, UITextView, UIScrollView, ...
    UIControl subclasses: UIButton, UISegmentedControl, UITextField, ...
  Common tasks
    UI elements:
      drag from Object Library, create an outlet/action  
    app layout: 
      constraints, stack views
    navigation:
      hierachical vs. flat vs. content-driven design
      show vs. modal segues, navigation bar, tab bar
    images:
      UIImageView, app icons
    specialized views:
      UIScrollView, UITableView, popovers
    sensing:
      motion events (e.g., shake), touch gestures (e.g., swipe)
    timing:
      Timer class, scheduledTimer method
    HTTP requests:
      URLSession, URL, URLRequest, DispatchGroup
