Basic Tasks
Just as an artist must know how to use a paintbrush and a musician must be familiar with scales and chords, a programmer must know how to do some basic tasks in code.
To create an iOS app, you need to know how to create objects, compare objects, query objects for information about them, and access objects in collections such as arrays. These tasks are common in iOS apps. After you acquire these skills, you are ready to take on more complicated Objective-C code.
