Barefoot Solutions is an agency that develops mobile applications for businesses in San Diego, California. This company holds various certifications in computer programming and software engineering. Such skills are surely useful for the development of custom iOS apps. The company's in-house programmers like to use the Xcode suite to build the back end of apps for iPhones and iPads. This is an open source software that supports some of the web's most powerful programming languages including C++, Swift and Objective-C. Debugging tools are also available in the Xcode program that is typically launched on Mac computers. Additionally, emulators could be used to check if prototypes work well in beta mode. Scripts that do not get validated by emulators should be reviewed and refined for the latest edition of iOS. Barefoot Solutions makes sure to comply with the development standards that have been set by Apple and other major IT players.
