Swarm is an independent IT company that serves clients in New York City. When it comes to building mobile apps, this firm prefers to do so for the iOS platform. Swarm specializes in developing custom apps for the iPad, which dominates the tablet marketplace on a global scale. Swarm utilizes the latest edition of Swift syntax to launch apps for the iPad. Having a closed source license, such technology exclusively belongs to Apple. The developers at Swarm are also familiar with other computer programming languages that are suitable for iPad apps. For example, the application programming interface (API) for an iOS app must include some elements of Objective-C and C+. Additionally, Apple's Cocoa Touch technology has to be integrated into the user interface (UI) of an app that is developed for the iPad. The final stage of app development for this tablet involves some debugging that can identify errors in source code.
