When we think about creating an iPhone application, it is very important to be very detailed in design and usability, since it is what users will perceive. According to the book “Designing apps for mobiles”, in order to successfully develop an iPhone app, it is necessary to follow these 5 stages:
Conceptualization: investigate and formalize the idea. It is very important to start with an idea that covers a need or facilitate an activity in the real world.
Definition: at this stage, designer / s and developer / s proceed to define the functionalities of the iPhone App in accordance with the profile of the users and the technical specifications. All this will allow determining the scope of the project, its duration, economic cost and complexity of the design and programming of the application.
Design: here aspects of specifications, functionalities, etc. materialize. The first scheme without graphics (wireframe) must be designed to test it with a group of users. After passing this first test, the final design must be submitted to the developer to add the programming code.
The design of the application will significantly influence both the economic cost of it and its development. There are four great design profiles that can be applied to the different platforms that exist:
– Multiplatform design: or also generic calls. Based on HTML5 programming and with a specific component for each type of device. It is the most economically viable option but the most limited in terms of its functionalities.
– Hybrid Apps: the designs of flows, navigation, and graphics share a large percentage of common elements, which allows reducing costs and time; but in these cases it is essential to follow the “guidelines” of both Apple and Google, so as not to break the experience and intuitive navigability of the users of each platform.
– Native apps specific to each platform: in this case, it is necessary to design as many times as platforms to be programmed. Some elements can be reusable and common, but it implies a higher design and development cost. This type of applications is the most optimal and the one that takes advantage of the functionalities of applications and devices.
– Design for iPad and Tablets: in this design profile there are two techniques:
Adaptation by “padding”: padding is an attribute that creates a space inside the box to which it is applied without touching or exceeding the edge, in order to adapt to the viewing surface. This has no design cost since it can be built by programming.
Specific design: it is ideal but it will depend a lot on the requirements of the app. Involves redesigning each screen to get the performance of the Tablets.
Development: in this stage, the programmer will be in charge of giving life to the designs and creating the structure on which the operation of the application will be supported, creating the functional code through the Swift programming language.
Publication: an application is published after a period of tests, where it is verified that it works correctly and that it is stable, without errors of usability and design and, above all, complying with the policies and requirements of the stores.
Finally, it is necessary that during the useful life of the iPhone application development, an analytical, statistical and user comments follow up, to evaluate the behavior and performance of the app, detect, correct errors and make improvements or updates for maintaining the success of the application.
