The iOS ecosystem remains in bloom due to Apple placing utmost emphasis on quality, privacy, and performance. On the shoulders of this crown lie two paramount technologies—Swift and SwiftUI—that allow developers to develop slick, contemporary, and efficient apps for iPhone users.
Should you want to build a high-performing iOS app in 2025, it is imperative to choose the correct talent well-versed in Swift and SwiftUI. How do you pick one from the vast sea of freelancers and agencies?
We at Developer Per Hour have helped businesses from all over the world to work with the best iOS talent and have two million other jobs under our belt. Let us consider these six practical suggestions for hire iPhone app developer who will convert your iOS app vision into reality.
1. Hire Based on Actual Swift & SwiftUI Real-World Experience
Many resumes out there can claim the skills of Swift and Swift UI, but project experience is what matters. Swift is Apple’s language of choice for iOS development, and SwiftUI is the new age in how developers build user interfaces.
Look for iOS developers who have developed live apps using Swift and SwiftUI, and not just those who have done courses or sideways projects. Reviewing their portfolio or requesting App Store links can go a long way in giving you a very clear understanding of their true capabilities.
At Developer Per Hour, every iOS expert must pass through rigorous vetting procedures that ascertain they are real, world-experienced, and not just theoretically knowledgeable.
2. Check Their Understanding of Apple’s Human Interface Guidelines
User experience is everything on iOS. Apple has strict design and usability principles outlined in its Human Interface Guidelines (HIG). A developer who understands Swift and SwiftUI—but doesn’t align with Apple’s HIG—may build an app that feels clunky or unfamiliar to iPhone users.
Anyone who wants to hire iPhone app development talent should ensure that said individual is well-versed in Apple’s design patterns and can construct intuitive and consistent interfaces compatible with SwiftUI’s declarative syntax.
This becomes even more important if the project requires a polish that will meet the threshold of good user experience for App Store-ready applications.
3. Seek Cross-Collaborative Skills
An extraordinary developer is simply not a coder, but an equally good collaborator. Whether a lifestyle app is being developed or, say, a financial technology platform, developers must work out issues with the UI/UX designers along with product managers and QA teams.
Ask the candidates something about how they work in teams, receive feedback, and their preferred use of controls, probably through Git. The best iOS developers know how the source code exists in the wider scheme of your product requirements.
Being a mature iOS mobile application development company, Developer Per Hour ensures that every developer we hire can easily blend into your team structure, whether remote or in-house.
4. Look Into Their Knowledge of Performance and Optimization
Swift and SwiftUI will always be fast, provided they’re used right. Developers should be able to optimize view rendering, manage memory well, and reduce app startup time.
Consider this, especially when these are designed to allow dynamic content, frequent user interaction, and even offline functionalities.
Ask technical questions before you hire anyone: background tasks, API calls, lazy loading. You can request a code sample to better assess their technical depth or even have a live coding assessment.
If you have an app to build, then Developer Per Hour is the right choice to make sure you get an application that is not under-optimized and provides a smooth and fast user experience. We specialize in delivering top-notch iOS app development services.
5. Ace Your Apple Development Ecosystem Question
An iPhone app is rarely built in a vacuum. It usually gets connected to services like iCloud, Apple Pay, Core Data, HealthKit, or MapKit. Depending on what your app does, your developer should know about integrating Apple APIs and services securely.
A professional developer will also know how to handle provisioning profiles, certificates, and the App Store submission process, which can be pretty confusing for non-technical founders.
It is where having a trusted and reputable iPhone app development company like Developer Per Hour will work to your advantage. We don’t just do the coding; we take care of the complete lifecycle of your app, from development to deployment.
6. Get Developers Who Understand Business Goals
Your app is a business asset, not just another third-rate digital product. That is why the very best developers think outside the coding box. They throw questions like:
Who is the target audience?
What problem is the app designed to resolve?
How will success be measured?
When you engage iPhone app developer talent through a trusted partner, you should expect some strategic thinking to accompany technical execution.
At Developer Per Hour, we ensure that our developers take a consultative approach—grasping the goals, suggesting potential improvements, and helping you to make decisions that have long-term value.
Why This Matters More in 2025
Since 2020, there has been a very rapid evolution in the iOS platform. With each yearly release, new capabilities get added, older APIs are deprecated, and the level of maturity of Swift and SwiftUI continues to increase.
To build a future-ready app, you will want app developers who are not just up to date but are ahead of the curve. And this becomes more relevant as user expectations continue to rise and competition across the App Store intensifies.
Rather than juggling many freelancers or being wary of untapped talent, work with a team of experts specializing in iOS mobile app development, such as Developer Per Hour.
