Challenges
Fragile WebViews Causing Enrollment Drop-Off
The client needed to boost customer enrollment by replacing unreliable WebViews with a smooth, consistent, and fully native enrollment journey.
Have a Similar Problem?
Modernize mobile flows and boost enrollment reliability.
WebView unreliability
Login sessions often broke, preventing customers from completing enrollment. This inconsistency led to frustration, additional support tickets, and lower trust in the loyalty program.
Customer frustration and drop-off
WebView screens loaded slowly and lacked native responsiveness. Many users abandoned the process, causing missed opportunities to grow program participation.
Fragmented integration paths
Enrollment had to work from sign-in, onboarding, and account creation. Without a unified solution, teams risked creating overlapping, inconsistent implementations.
Legacy system constraints
The host app was a large, UIKit-based legacy codebase. Introducing SwiftUI without breaking existing flows required careful design and coordination.

Workflow
Native SwiftUI in Production
The team followed a focused, development-driven process to transform designs into a live, reusable, and stable SwiftUI flow that seamlessly fit enterprise requirements.
Phase 1
Business goal alignment
Reviewed Epics and requirements to link the rebuild directly to long-term loyalty program engagement targets.
Phase 2
SwiftUI implementation
Translated Figma components into four SwiftUI screens using MVVM, ensuring performance and scalability.
Phase 3
Coordinator integration
Created coordinator objects to orchestrate multiple screens into a single flow, while also enabling entry from multiple points in the app.
Phase 4
Backend connection
Integrated with backend services for OTP validation and conditional credit card checks, while handling all edge cases.
Phase 5
Cross-team enablement
Exposed a reusable coordinator API so other teams could trigger the new flow easily without code conflicts.
Phase 6
Future roadmap
Extended analytics to track completion rates, add advanced video usage reporting, and explored Android parity for cross-platform consistency.
Replacing unreliable enrollment screens with a stable, modern flow strengthened trust, reduced drop-offs, and created reusable building blocks that streamline future mobile experiences.
Solution
Native Loyalty Enrollment with Reusable Components
Delivered a stable, extensible sign-up journey alongside a shared video player component that powers both loyalty celebrations and dynamic marketing campaigns.
Four new SwiftUI screens
Implemented phone number input, OTP validation, optional credit card verification, and a celebratory welcome screen. Together, they replaced all fragile WebView enrollment pages with a fast, stable, and intuitive native experience.
Coordinator-driven integration
Built coordinator objects to unify presentation logic. This ensured that enrollment could be triggered consistently from multiple app surfaces while keeping code maintainable across teams.
Reusable SwiftUI video module
Created a lightweight, AVPlayer-based SwiftUI wrapper as a separate module. This powers both the confetti-style celebration screen and homepage marketing videos, enabling greater creative flexibility.
Risks and Mitigations
Managing Complexity and Ensuring Reliable Testing
The project faced technical and process challenges around multiple entry points, OTP testability, and legacy UIKit coexistence—but each risk was addressed with targeted mitigations.
Option |
Risk |
Mitigation |
|---|---|---|
| Multi-entry coordination | The enrollment flow had to be invoked from onboarding, sign-in, account creation, and more, raising the risk of duplicate or inconsistent logic. | Enabled a centralized coordinator object ensured consistent handling, enabling future extension without conflict. |
| OTP testing limitations | The US test numbers were unavailable, blocking full end-to-end validation. | Collaborated with backend teams to build a non-production workflow, retrieving verification codes via Postman for any test number. |
| Legacy UI kit coexistence | Mixing SwiftUI components with a massive UIKit codebase risked instability and regressions. | Established MVVM boundaries and created wrapper components, validated through technical spikes before production rollout. |
Results
Stronger Enrollment Experience and Reusable Marketing Surface
A native SwiftUI experience improved reliability, sped up onboarding, and unlocked reusable components that now support multiple teams.
The project replaced unstable WebViews with a resilient native journey and delivered a reusable video module, supporting both loyalty engagement and marketing innovation.
Higher enrollment reliability
Native SwiftUI flow eliminated WebView session failures, ensuring more customers could successfully complete enrollment.
Faster and cleaner UX
Customers enjoyed smoother onboarding, faster screen loads, and fewer interruptions—leading to stronger trust in the loyalty program.
Cross-team adoption
Other teams quickly reused the shared video module, accelerating development of new marketing surfaces and reducing duplicated effort.
Business Value
Strengthening Loyalty Engagement
By replacing fragile WebViews with native SwiftUI flows, the client removed barriers to customer enrollment while laying a scalable foundation for tomorrow’s enterprise mobile strategy.
Frictionless loyalty growth
The stable enrollment flow supports the client’s strategic goal of growing loyalty program participation, reducing technical and UX barriers that previously hindered sign-ups.
Foundation for app modernization
As one of the first fully SwiftUI flows in a large UIKit estate, this project created a repeatable blueprint for future modernization efforts, ensuring smoother adoption of new technologies at enterprise scale.
