Um estudo comparativo entre padrões arquiteturais para o desenvolvimento de aplicativos para a plataforma iOS

Abstract

The smartphone evolution has brought increasingly powerful, complex and interactive applications for mobile devices. In this category, software developers face new challenges to meet industry’s ever-growing criteria and user’s demands. The State of the Art of applications development has a wide framework of documents which offer several APIs to help developers from the basic to the most sophisticated levels. This framework comes with a high cost of maintenance due to constantly changing source-codes, which in turn might be required for a large range of reasons. In this context, a mobile application designed from a pre-existing architecture and supported by strong project patterns may benefit in crucial aspect such as reusage, testability, modularization and low coupling, allowing changes during the application’s life cycle and limiting undesirable impacts. However, as popular as these solutions may be, only a few academic works have addressed its real gains. Here we compare two architectural patterns for applications development in iOS devices and evaluate the impacts of an architectural change in the early stage of a developing process.
