Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2017, Director: Sergio Sayago Barrantes[en] The development of software for the iOS platform have become in recent years an important part of the software development sector. The speed at which the complexity of the software to be developed has grown, has made the architecture models used to date obsolete to meet the needs of a long-term development. In this paper, the existing architecture models for the development of iOS applications will be studied and documented. After that, software design patterns will be used to design and document an architecture proposal with which to try to ensure the sustainability of an iOS software project. Finally, the proposed architecture model will be applied in a software development by way of example, giving rise to an application for iOS, trying to guarantee the understanding of this work, and contribute all my analysis with the proposal model, to the paradigm of application development for iOS.
