Basic resources for iOS developers

The App Store is full of applications. Most of them are written in the Objective-C programming language, the native language to develop apps for iOS, basically iPhone and iPad. Other options to build iOS apps include JQuery, HTML5, C and other programming languages. There are also websites and platforms to build basic apps by dragging and dropping buttons, labels and images.  However, the native iOS is the best option in terms of performance, management of resources and user experience.

Apple provides lots of resources to help developers build their apps. Native apps are built using XCode, Apple’s IDE (Integrated Developer Environment) which includes tools to build the app’s interface, program the code, simulate the app on a simulator, and test the memory, CPU and resource usage. The apps are programmed using Objective-C, the Apple’s object oriented programming language.

To build an iOS app, developers must use a Mac OS X since other operating systems are not supported. The development tools needed are iOS SDK and Xcode. Both are free of charge and available on the Apple’s Developer Website. These tools allow any developer to build and test it using the iOS simulator, which is part of the iOS SDK. However, to run the app on a real device, developers must pay $99/year, which includes the license to publish unlimited apps in Apple’s App Store.
