iOS App Development using Swift 4



Overview

This intensive 5-day course is designed to train both novice and experienced developers how to create native iOS 11 Apps for the iPhone, iPad and iPod using the Swift programming language.

Created by experienced iOS developers, the course places a very strong emphasis on hands-on learning through a multitude of exercises and demonstrations. Students will be guided through a wide variety of in-class Labs specifically designed to offer practical solutions to common problems that address real-world production needs. Topics covered include: Multi-View Apps, Design-Patterns, Data-Persistence, Core Data, Web-Services, JSON and XML parsing, Maps and Location Services, working with Images and Animations, and handling Gestures.

An in-depth look at the Xcode 9 IDE and its many features and tools will also be included.

Course Objectives

  • Learn to use Xcode 9's Interface Builder to design and build iOS App Interfaces.
  • Utilize iOS Controls such as Buttons, Switches, Sliders, and Pickers.
  • Build multi-screen Apps using Navigation Controllers, Master-Detail (drill-down) templates, and the Tab-Bar Template.
  • Data Persistence – saving data on iOS devices using Property List, Sqlite3 Databases, and Core Data
  • Make calls to Web-Services from an iOS App
  • Parse incoming JSON and XML data streams
  • Work with Maps and Location Services to make location-aware Apps
  • Gesture recognition, enabling Swipes, Taps, Pinches, and Pans
  • Use of Auto-Layout and Size Classes to properly configure Apps to support various screen sizes, device orientations (Portrait and Landscape) and devices: iPhone SE's, 6's, and 7's, 8's, iPads, iPad Minis, etc.


Prerequisites

  • Basic knowledge of programming in Swift is recommended to get the most out of this class. (Note: a separate 3-day "Programming in Swift" class is also available.)
  • Object Oriented Programming experience is recommended
  • Basic familiarity with Mac computers and working in Mac OS X is recommended
