Using XCode for IPad Programming

Learn how to use the xCode suite for iPad App Development

xCode is a suite of applications designed by Apple to be used in a programming environment for multiple purposes and developments. Similar to Microsoft’s own Visual Studio yet still unique in its own way, xCode incorporates Cocoa and Cocoa Touch in an integrated development environment and supports many programming languages including C, C++, Objective-C and Java. xCode is developed by Apple as part of the core components of MAC OS X or OS X. Since iPhone OS (or iOS) is built on the same kernel as MAC OS X, it is essentially a version of OS X as well, thus one can develop applications for the iPhone and the iPad using xCode. The xCode suite is comprised of the main program, xCode, most of Apple’s developer documentation and an Interface Builder.

Combined with the iPhone SDK, developers can compile, test and debug applications for use on the iPad and iPhone.

To begin developing an application within xCode, you may have to have past familiarity or understanding of programming languages such as C, C++, Objective-C, Objective-C++(which were developed by Apple as part of MAC OS X) and JAVA as well.

To develop your application you will use the xCode IDE and Apple’s modified version of the free GNU Compiler Collection. To ensure that an application developed with xCode is on track, it is recommended that you draw up an application build plan that covers details on how your application will function, what features it will have and how it will work within the core iOS environment. With the release of iOS 4 and iPad, as a Developer you will now be building Applications that cater for 2 similar yet different products, the iPad and the iPhone. Although they use the same APIs, their different features have to be considered in order to build fluid applications. Compiling most of your code will be done with xCode IDE, using your preferred programming language. xCode suite provides all the relevant documentation you need to develop your application, more specifically for the product model, you will use.

The coding process will probably take up most of your time, your application building plan will help you chart the way. Using the xCode IDE, you can also test and debug your coding to see how it compiles itself. One of the advantages of xCode is how it operates with Cocoa Touch, which is the core of the iOS’s amazing touch capabilities.

Using the Interface Builder tool, you can design the GUI or visual plan of how your application will look like. This part usually comes towards the end when you have done most of your compiling for your application. Keep in mind that your application’s GUI will bank on the outline of either the Apple iPhone or iPad screen resolution. The iPhone SDK with xCode tools also includes a simulator for simulating your application(s) both for the iPhone and the iPad as well.

xCode gives you access to all the necessary tools you need to master the MAC OS X/OS X kernel platform and build applications that are efficient and function wonderfully on the Apple iPhone and iPad. You may also want to read about How the iPad changed Programming.
