A top Boston-based healthcare provider faced major performance issues with their legacy iOS patient app. It was built nearly a decade ago and couldn’t keep up with modern UX expectations or security needs.
That’s when they turned to expert Boston iOS developers, a local team known for modernizing enterprise mobile apps using SwiftUI—Apple’s latest UI framework. Within six months, the team rebuilt the app from scratch, significantly enhancing performance, security, accessibility, and patient satisfaction.
Why the Client Needed a Rebuild
The legacy app had become a liability. Here’s what the healthcare organization was struggling with:
- Crashes and lagging on iOS 15 and above
- Lack of support for accessibility tools (voiceover, dynamic font sizing)
- HIPAA compliance gaps
- A dated UI that frustrated users
- Incompatibility with Apple HealthKit
This is a common issue among healthcare firms with aging digital infrastructure. Partnering with the right software development companies—especially those with local healthcare tech experience—is key to navigating this challenge.
How Boston iOS Developers Approached the Project
How did the Boston iOS developers start the rebuild?
They kicked off the project with a comprehensive app audit:
🔍 Discovery Phase Steps:
- Code Review: Identified deprecated Objective-C code and obsolete libraries.
- UX Audit: Mapped current UI/UX flows and user pain points.
- Security Check: Flagged HIPAA violations (unencrypted endpoints, outdated TLS).
- Integration Review: Assessed backend APIs and third-party systems (e.g., lab results, appointment scheduler).
Once the pain points were clear, the team proposed a full SwiftUI rewrite for future scalability and maintenance.
Why SwiftUI Was the Right Choice
What is SwiftUI and why was it selected?
SwiftUI is Apple’s modern declarative UI framework designed for faster development and better performance across Apple devices.
🎯 SwiftUI Benefits:
- Cross-device compatibility (iPhone, iPad, Apple Watch)
- Reduced boilerplate code = Faster releases
- Real-time previews for faster UI testing
- Accessibility support built-in
- Smooth integration with Combine for reactive data binding
Choosing SwiftUI allowed the Boston iOS developers to create a more modern, fluid, and secure experience in less than half the time of UIKit.
Key App Improvements Delivered
What did the new app actually improve?
The developers worked in two-week Agile sprints, releasing features iteratively and keeping stakeholders in the loop. Here’s a breakdown of what changed:
🔧 Major Feature Improvements
| Area | Old App | New SwiftUI App |
|---|---|---|
| UI Design | Flat, outdated visuals | Clean, intuitive UI with dark mode |
| Performance | Laggy and crash-prone | 40% faster load time |
| Security | No SSL pinning | HIPAA-compliant, AES256 encryption |
| Scheduling | Slow and buggy | Smart calendar integration |
| Notifications | Basic push alerts | Interactive, local & remote alerts |
| Accessibility | Not supported | VoiceOver, Dynamic Type, Haptics |
User Feedback & Results
How did users and the healthcare provider respond to the update?
After a soft launch in the Boston area, the new app saw tremendous success:
📊 Metrics 90 Days Post-Launch:
- App Store rating: Increased from 2.1 ⭐️ to 4.8 ⭐️
- Crash rate: Dropped by 93%
- Session time: Increased by 65% (users completed more tasks per visit)
- Appointment bookings: Up 28%
- HIPAA audit score: 100% compliance
👩⚕️ Client Testimonial:
“The Boston iOS developers exceeded our expectations. They didn’t just rebuild our app—they transformed how we serve our patients. Our internal IT team is thrilled with the maintainability SwiftUI provides.”
What This Means for Other Healthcare Firms
Should other healthcare providers consider rebuilding legacy apps?
If your app was built before 2018 and still relies on Objective-C or outdated UIKit patterns, the answer is likely yes. Especially with the increasing importance of:
- Telehealth and remote care
- Patient-centric app experiences
- Integration with wearable data (Apple Watch, Fitbit)
- Ongoing HIPAA compliance
Boston iOS developers and other local software development companies are now leading the way in modernizing digital health solutions—bridging the gap between medical expertise and mobile-first expectations.
