SFCD is an award-winning IT agency that holds an office in the San Francisco Bay area. Since opening its doors, this company has closely followed the evolution of Apple, which is based nearby in Silicon Valley. When local clients request the custom development of apps for the iPhone, this firm knows exactly which tools to utilize. As the official integrated development environment (IDE) for iOS, the Xcode suite is used to build the framework for all iPhone apps that are listed on the iTunes store. Featuring drag-and-drop instruments, this is an advanced software that accelerates the design process. The programmers at SFCD use the latest edition of the Swift programming language to synthesize the code for iPhone apps. This open source syntax has an open source classification that's compatible only with Apple software. Additionally, the signature Cocoa Touch standard has to be implemented to define the interface of an iPhone touch screen.
