# App Development Summer Camp NYC (High School) Canonical URL: ## Overview Throughout this 45-hour iOS summer course, students will learn to develop several apps, including two in the very first week! Our curriculum begins with basic programming concepts in Xcode playgrounds and then moves into more advanced topics using Xcode 9 and Swift 4. Students will complete step-by-step activities to code working apps, including a tip calculator and a weather app that integrates with an API (an Application Program Interface, which enables developers to program software components to work together). After learning new skills and techniques in class, students reinforce important concepts by developing their own final project at home, with tons of instructor guidance along the way! **Prerequisites & Ages:** The program is ideal for ages 13-19 with a strong interest in coding. Prior coding/programming experience is not required, but students must be comfortable with computer basics. ## What you'll learn - Learn to build and develop apps using Swift & Xcode - Create numerous real-world apps - Add interactive elements such as buttons, taps & swipe gestures - Connect the user interface to code that makes the app work - Learn programming concepts and logic to create an efficient app - Add image assets for your apps, launch screen, & app store - Build adaptable layouts that work across all iPhones & iPads - Add embedded videos, map location, external web links - Learn to use data models, including external datasets - Preview your apps on your own device - Create your own app with guidance from the instructor ## Curriculum ### Week 1 #### Introduction to Tools of the Course - XCode - iOS - Swift #### Hello World App #### Roll The Dice App #### The Swift Programming Language -

NextGen's typical class ranges from 10-14 students, but we allow up to 17 students to register for our course. However, NextGen always maintains an 8:1 student to teacher ratio. ### Do I make my own app during the course? During the course, students will build multiple apps as a class and will be able to work on their own projects at the end of the class. ## Pricing **Tuition:** $1995
