Learn about our development process
We are ready to support you at every step of your custom software development way, whether you have a ready-made concept for your iOS app or need assistance in defining the product vision. Each project adheres to clearly specified procedures to ensure the highest quality of our deliverables. Discover how our full-cycle software development process works in practice.
Product Discovery Workshops
The cooperation typically begins with Product Discovery Workshops, which we hold to understand the overall vision of your app and validate it. During
this stage, we attempt to obtain a business perspective on the entire project by learning about your company’s objectives, target audience, and fundamental values. Such information lets us define project goals and align the team with a detailed plan for its implementation.
UX/UI Design
Once we have a mutual understanding of your product vision, we are ready to turn it into a digital image. After researching the market and defining user personas, our team comes up with simple UI wireframes and then turns them into clickable prototypes. This stage results in the final version of your iOS app design consistent with your company branding.
Agile Development & QA
It’s time to transform your app’s visual representation into a functional product. At CrustLab, we follow Scrum methodology, which means our iOS developers create source code in time-boxed iterations. Individual components are evaluated on the fly, but the complete app goes through a comprehensive quality assurance process before it can be released to ensure that it runs correctly. As we prioritize transparency and open communication with our clients, you are welcome to actively participate in the entire process.
Deployment
After careful development and testing, your iOS application is now ready for release. At this stage, we prepare the necessary infrastructure and create scripts to automate the deployment process and ensure a timely launch. Last dry run before going live, and all done! Your app is officially on the App Store.
Maintenance
We deeply care for our partners and their products and our work doesn’t end once the app is launched. Our development process includes the maintenance stage, during which we make sure that your product remains compliant with any new requirements and continues to function properly. Fixing bugs, updating the design, or enhancing the app with new features is also on our side.
iOS development tech stack
Take a look at the technology stack we use in the native iOS app development process.
Programming language: Swift

Frequently Asked Questions
Would you like to learn more about iOS development? Here you will find answers to the most commonly asked questions.
-
Native iOS vs cross-platform app development – which one should I select for my project?
The choice between cross-platform and native iOS mobile app development depends on a number of factors, including the specific requirements of your project and your budget.
Building a mobile app in cross-platform technology allows you to create solid software that can run on multiple platforms using a single source code, which will probably save you a lot of time and money. That’s why we recommend this solution to businesses that value product quality but have limited funds.
Yet, you should be aware that despite its close-to-native UX and development efficiency, cross-platform apps still have their limitations in comparison to native ones.
Native iPhone app development services not only offer more flexibility for the refinement of UI components, but also fast and smooth data processing, which is absolutely essential for demanding Apple users. So, if your application’s performance and visually appealing design are important to you, going for native technology will probably be a better choice.
Before making a final decision, we advise you to go over your project’s requirements and budget with a software development agency. Reach out to us and we will discuss it together.
-
How much time does it take to develop an iOS app?
As with all software development projects – it depends. The two factors that play a crucial part in defining the timeline are the scope of the project and the features you want to incorporate into the app.
Typically, it takes us around 6 months to deliver a standard iOS application, but this estimate can vary depending on the project’s complexity. We can build basic apps in a matter of weeks, but more complex systems with a large number of features and outstanding UI generally take longer.
Remember that choosing a competent and reliable iOS mobile app development company can shorten your product’s time-to-market and improve the quality of custom iOS app development services.
-
How much does an iOS app cost on average?
The cost of developing an iOS app can vary depending on the app’s complexity. Yet, based on our prior projects and market knowledge, we can assume that:
- a simple mobile app for a single platform costs from $20,000 up to $50,000,
- a more advanced application for a single platform requires at least $50,000 up to $100,000 or so,
- a fully complex app costs $100,000 and above.
Keep in mind that these are just averages. Contact us to get a more accurate estimate for your iOS app development.
-
Do you have the experience with the technology stack that I need?
Yes, we are competent with the technology stack required for iOS app development. Our team is proficient with Swift and Dart programming languages and databases like Firebase and Realm.
We also have vast experience working with iOS frameworks like UIKit, Appolo, and XCFramework and different iOS architectural patterns like MVVM+C, Clean Swift (VIP), FLUX/REDUX, or SPM, allowing us to create a stable and user-friendly iOS app that exceeds your expectations.
-
Will you upload my app to the Apple Store?
Yes, of course. Our iPhone app development services include uploading your application into the App Store. We also double-check if the app meets all the obligations and responsibilities for the use of Apple services to ensure it will pass the review. As a full-service mobile app development company, we will also provide you with instructions on how to manage information on your App Store product page.
