This video is a quick look at Swift, Apple's latest programming language for iOS development. Swift is the language that most iOS work will be done in going forward.
- [Instructor] All Swift classes…have the same basic structure.…Many Swift classes make use of classes…declared inside frameworks.…Frameworks are collections of classes and resources…that perform a specific task.…To use a framework and their resources,…they must first be imported.…Import statements are placed outside the class declaration.…The class declaration is where you name your class,…specify a superclass, if any,…and specify any implemented categories and protocols.…The class definition is placed…inside the class declaration's curly braces.…
The class definition is where you…declare variables and methods.…For the most part,…the order in which you declare them doesn't matter.…The class definition may include instance variables,…which are variables whose scope is the entire class.…They are called instance variables…because each instance of the class…can have its own values for the variable.…Instance variables represent the properties of an object.…Many Swift classes include constructors.…Constructors are special methods in Swift…
