Objective-C defines a small but powerful set of extensions to the ANSI C programming language that enables sophisticated object-oriented programming. Objective-C is the native language for Cocoa programming—it’s the language that the frameworks are written in, and the language that most applications are written in. You can also use some other languages—such as Python and Ruby—to develop programs using the Cocoa frameworks. It’s useful, though, to have at least a basic understanding of Objective-C because Apple’s documentation and code samples are typically written in terms of this language.

A splash screen is the first screen you see when launching an application. Usually, splash screen is an image covering the entire screen and disappears after the main screen is loaded. This makes the app look like it is loading faster. First, you will need to create an image with the PNG format. Your image resolution and name should follow Apple Human Interface Guideline. By default, name the image file for lower screen resolution as "Default.png". For the image intended for Retina Display, name the file as "Default@2x.png". The "@2x" is a standard scale modifier used in iOS. After creating your images, add the images to Xcode by right clicking on the project and select "Add files to project."
