SFCD is an independent IT agency that has private design studios in New York City and San Francisco. Being so close to the corporate office of Apple, this web design firm naturally loves the iPhone and other gadgets that run on the iOS platform. The back end of an iPhone application is usually encoded with the Swift programming language. This is an open source syntax that can be combined with other scripts and codes that define web apps. For example, Objective-C plays a key role in supporting the framework of iOS tools. Additionally, C++ can add some extra dynamic value to an iPhone app that's supposed to run smoothly on the Safari web browser. SFCD publishes all of its digital solutions on the iTunes store that is easily accessible via Apple's mobile devices. The iTunes marketplace also allows users to rate and review any apps that are available for download.
