1. Discovery phase

Before any production work can begin on your app idea, a discovery phase is an important first step. By gathering information and nailing down any objectives, you’ll have a clear idea of what problems you’re trying to solve with the project before starting to really firm up the concept. This is also a time to see what else is out in market, identify your audience, and pull together any market research pertinent to the project.

2. Concept phase

This is the concept phase of your application—you’ve done your research, and you’ve got your objectives and value propositions laid out. This is the time to lay important groundwork for your app. With the help of a product manager, this is when you can really refine your idea, get a developer to weigh in on the app’s functionality early on, write up a specification document, and a technical specification document.

3. Goals

A spec document lays out the business logic of the app, while a technical spec document scopes out the features and functionality of the app. This will help you determine the requirements of the app, and whether or not you’ll need server-side support and integration. (For example, a utility-style app like a flashlight does not require server or database support. A messaging app, however, will.) Common technical aspects to consider include: do you have an Apple Developer account to publish the app through? Will the application be written in Objective-C or Swift ? We prefer to use swift.

4. Wireframe phase

Once the tech specification document is written—translating all of the features of your app into specifications for your development team—it’s time to create wireframes. Wireframes act as a user experience (UX) roadmap—demonstrating what a user’s options will be—and an information architecture blueprint, laying out which parts of the site will have what content. A good wireframe hinges on excellent UX as well as user interface (UI) design, so engage a designer at this phase to help think through a natural flow for your app. Establish and approve what content goes where in your app, and the flow of the user experience with wireframes. This is the next phase of your tech spec document, demonstrating how the app will come to life.

5. Design & Architecture

At this phase, you’ll want to consider a few different angles: creating an appealing visual design (how it looks), an intuitive UI (how it works), and an engaging UX (how it feels to the user). For more information, read our article describing the differences between UI and UX design. A designer will create the look and feel of each screen of your app, with all of the graphics, icons, custom animations, and more that will visually define your app. The designer will also be generating design prototypes for the development team. Any graphics created will be imported into the Xcode development environment, and the designer will remain engaged through the development phase, as developers may come back with problems or ideas the designer may need to address.Create design mockups and prototypes for the development team. Establish the design system for the application, a style guide, and the patterns used in the application. This phase is collaborative with the development phase—expect some back and forth between designer and developer.

6. Software Architecture Planning

Scalability is one of the most important things for a mobile application—it has to be written to support growth from the very beginning. “Architecting” an app at this phase is crucial and could prevent you from having to completely rewrite it when it needs to grow. This phase happens parallel to design so you’re ready to kick off the development phase next.Create a cohesive plan for the software architecture of the app—both the front-end architecture and the back-end architecture. If you’re opting for a backend as a service (BaaS) software bundle, there will still be integration required.

7. Front-end & Back-end Coding & Integration phases

This is the most complex phase—expect many iterations, with a constant feedback loop between your designer and your developer along the way. At this phase, both the front-end and back-end architecture of your app are built as a coordinated effort. While your app’s functionality is created, its system architecture is getting built. The front-end interface and the back-end server support software are dependent on one another, and the process usually involves a lot of back and forth.
On the front end, you’ll be making decisions about how your app’s functions come to life with code—its computing logic. A few technologies you should know when you discuss options with your mobile app developer include:
Xcode. In the development phase, your iOS developer will use Xcode—Apple’s integrated development environment (IDE)—to create your native iOS app, importing any graphics created by the designer. This tool provides a ton of features to create a native iOS app, like designing the UI, editing source code, debugging, and even exporting the app to the App Store. The Interface Builder is an alternative to hand coding the front end, allowing developers to put the app’s code together visually. iOS programming languages
Objective-C. : Cocoa Touch is built on the Objective-C programming language—a superset of the C programming language with an added object-oriented programming layer. iOS apps are networks of objects, objects are Objective-C classes, and classes can be pulled from the Cocoa framework, or written from scratch.
Swift. : Apple’s newest programming language Swift was launched in 2014 and is quickly replacing Objective-C. It’s easier to learn, simpler than Objective-C, and Apple claims it runs 2.6 times faster. Objective-C’s syntax, while verbose for a programmer, was a good fit for early iPhone hardware—less RAM and slower processes. Swift keeps up with modern hardware and is also faster on the coding end, shorter, more secure, and easier to maintain. Read more in our Swift vs Objective-C article. Frameworks. iOS apps are built with the Cocoa Touch framework, a version of the Cocoa framework that’s focused on touch-based interfaces. The Foundation framework provides an app with basic services, written in Objective-C. Hybrid apps are built with front-end frameworks like Bootstrap, jQuery mobile, and AngularJS on third-party platforms like Xamarin, PhoneGap, or Appcelerator—options that let you code cross-platform apps with languages other than Objective-C. At the same time, any back-end engineering—any server-side components your app needs to run, like a database, APIs, middleware, etc.—are coded and integrated in this phase, linking them to the front end.

8. Testing Phase

Thorough quality assurance testing is up next—and Apple’s submission and approval process is notoriously more difficult than Google’s, so this phase can be crucial. In testing, your developer will go all the way through your app on a device or in the Simulator of Xcode, screen by screen, to ensure there are no bugs and everything works smoothly. Debugging can be done right in Xcode. Cover all your bases when you test. You’ll need to test across different devices (iPhone, iWatch, iPad, iTouch) as things like battery life, screen resolution, processors, and memory will be different and affect how your app runs. Test for functionality (does it work well?), load time and handling (does it slow down when traffic increases?), and UX (how easy is it to learn or get used to?). Also, review any crash reports to locate fixes. Ensure your app runs well on all targeted devices without crashing, slowing down, or any bugs.

9. Submitting an App for Review

The submission process usually involves a few fixes and resubmissions, so it’s helpful to have a seasoned iOS developer who knows the ropes and what to expect. Getting your app live and in the App Store takes a few steps, including configuring the code, creating a profile, creating a listing, then submitting it through Xcode for certification.
