Halo Lab’s iOS development process starts with architecture — navigation patterns, state management, and data flow defined before any feature work begins.
We build in native Swift, implement UI from Figma, and handle everything from the first commit to App Store submission and engineering handoff.
3 main challenges holding back your growth
Outgrown identity
Your company has grown, but the brand no longer reflects scale or direction.

No defined app architecture
No architecture — maintenance costs compound from release one.
.webp)
Design intent lost in code
UI implemented inconsistently — design intent lost between Figma and code.

No engineering handoff
No handoff docs — new engineers take weeks to understand the codebase.
“All projects in which we’ve involved Halo Lab have been great successes, but their leadership on our brand refresh is worth highlighting.”
“We’ve had feedback from users, investors, and employees, and everyone has said that Halo Lab did a fantastic job with the branding.”
“We’re proud of their branding services. They not only do what we tell them but also make suggestions to help us improve our offerings.”

FAQ
Why invest in branding services?
Why invest in branding services?
What does iOS development include?
App architecture, native Swift development, UI implementation with UIKit or SwiftUI, API integration, push notifications, QA testing across devices, App Store submission, and engineering handoff.
Do you use Swift or Objective-C?
Swift is our primary language for all new iOS development. Objective-C is supported for projects requiring integration with existing legacy codebases that have not yet been migrated.
Can you implement our Figma designs?
Yes. UI implementation is pixel-aligned to your Figma specifications — component structure, spacing, interaction states, and motion behaviour all matched to the design handoff package.
How long does iOS development take?
Most iOS MVP builds take 3 to 5 months from architecture to App Store submission, depending on feature scope, backend complexity, and whether design is included in the engagement.
Do you handle App Store submission?
Yes. We prepare all App Store assets — screenshots, metadata, privacy policy compliance, and App Store Connect configuration — and manage the submission and review process through to approval.
Do you support older iOS versions?
We target the two most recent major iOS versions by default. Older version support is available and scoped during the architecture phase based on your user base and App Store analytics.
Do you integrate third-party APIs?
Yes. REST and GraphQL API integration — including authentication, payment providers, analytics, push notification services, and other third-party dependencies — are built as part of development.
Do you write unit and UI tests?
Yes. Unit tests and UI tests are written during development using XCTest — covering critical business logic, API interactions, and key user flows before the app reaches the App Store.
Do you offer post-launch iOS support?
Yes. Ongoing iOS development retainers are available — covering new feature builds, iOS version updates, bug fixes, and App Store asset updates as your product and platform evolve.
