There is an Assistant that shows exactly which part of the code is being edited, which can be the controller, the header or even the superclass. All the projects by the user are designed on this core facility only. The core of the application is an Interface Builder. In some case, the Xcode IDE is even known to fix the cases, which would definitely help the user go a long way with their development projects.
The Xcode IDE can easily analyze the project made by the user and even identify the mistakes or issues that can arise because of an incorrect logic or syntax. The debugging feature needs a special mention as it has improved the most over the years. As the years have gone by, they have even included testing, debugging and coding facilities, all in the same window.
The design and functionality of this application is definitely appreciable. Xcode was first released in 2003, but since then, the application has definitely come a long way in providing efficient development platforms to developers. Xcode is a great addition for those who are looking for a reliable tool for creating applications for Mac OS as well as the iOS for iPhones and iPad.
