Swift is a programming language created by Apple for building iOS and OSX apps. It is intended to make app development simpler and works seamlessly with Apple's frameworks and APIs. Xcode is the integrated development environment (IDE) used to create, test, optimize and submit iOS apps to the App Store. Key frameworks and APIs provided by Apple include those for navigation, media, camera, networking, maps, data storage and GPS. The frameworks handle repetitive tasks, but give developers places to run custom code.

5. Swift
• Released in 2014 by Apple
• Intended to make writing OSX and iOS apps simpler
• Works ‘seamlessly’ with Apple’s frameworks andAPIs

6. Analogy
• How are driving and flying different?
• What are the pros and cons of each?

8. Frameworks
• Inversion of control – the framework does most
of the heavy repetitive and otherwise mundane
lifting, but it also in the driver’s seat.
• Gives you places where you can run your code.
