Barefoot Solutions is a web design agency that adheres to the latest standards of mobile technology. More specifically, this company follows the guidelines that have been set by Apple. As a firm that designs mobile applications that run on the iOS platform, Barefoot Solutions deploys the Swift programming language. Originally launched by Apple, this syntax has evolved into an open source tool that can be applied by any developer without the need to pay for licensing rights. The software development kit (SDK) for iOS includes the Cocoa Touch framework, which is standard on the iPhone, iPad and iPod Touch. This technology regulates the dynamic nature of touch screens in Apple's devices. Without Cocoa Touch, it's impossible to build a functional iOS solution. After testing the source code of an app, Barefoot Solutions launches it on the iTunes store. At least once per year, this company also publishes some bug fixes and updates to its digital products.
