The iOS quality problem
Most apps fail App Review not because the idea is wrong. Because the build skipped the rules.
0%

What gets apps rejected
- Missing App Tracking Transparency prompt for trackingGuideline 5.1.1 • Instant rejection
- In-app purchase bypassed with external linksGuideline 3.1.1 • Instant rejection
- Privacy manifest missing for third-party SDKsRequired from iOS 17 onwards
- Crashes on specific device or iOS versionApple tests on multiple hardware configurations
- Screenshots do not match app functionalityGuideline 2.3.3 • Binary rejection
How Redefine prevents every rejection
- App Store readiness audit before every submissionApp Tracking Transparency, privacy labels, purchase flows verified first
- StoreKit 2 for all in-app purchases, no workaroundsApple-native purchase flow, always compliant
- Privacy manifest included for all required SDKsPreemptively meets iOS 17+ requirements
- TestFlight beta on real devices, not simulatorsReal iPhone and iPad hardware, same as Apple tests on
- Human Interface Guidelines compliance review on every screenHuman Interface Guidelines built into our quality assurance checklist
iOS development process
From Figma handoff to App Store approved in 14 weeks.
We run four development phases in parallel where possible, cutting iOS build time without cutting corners on App Review compliance. Every phase has a defined deliverable your team reviews before the next begins.

Common questions
What product leads ask before an iOS development engagement.
We build new iOS apps in SwiftUI with Swift 5.9 or later. For apps requiring UIKit integration or legacy codebases, we use UIKit with Swift. We do not use React Native or Flutter for projects sold as native iOS development. Native Swift apps respond faster, integrate more deeply with iOS hardware, and receive priority treatment from Apple for new operating system features like Dynamic Island, Live Activities, and StandBy mode.
A production-ready iOS app with authentication, a core data feed, push notifications, and App Store submission takes 12 to 16 weeks from Figma handoff to App Store approval. A focused minimum viable product with 4 to 6 screens and no complex backend takes 8 to 10 weeks. See our development process above for a detailed phase breakdown.
We build to Apple's Human Interface Guidelines, App Store Review Guidelines, and privacy requirements from the first sprint, not as a post-build checklist. We conduct an App Store readiness audit before submission: metadata, privacy labels, tracking transparency, App Tracking Transparency prompts, and in-app purchase flows. Our first-submission approval rate is high because we treat App Review as a hard technical requirement.
SwiftUI for new builds. UIKit when the codebase requires it or when the app uses UIKit-only components not yet available in SwiftUI. For large existing UIKit codebases, we use an incremental migration strategy: new features in SwiftUI wrapped in UIHostingController, with UIKit components retained until rewritten. We do not rebuild working UIKit apps in SwiftUI for its own sake.
iOS app development engagements run between $60,000 and $300,000 depending on the number of screens, custom animation requirements, backend complexity, third-party integrations, in-app purchase flows, and whether the scope includes ongoing maintenance. We scope before we quote. See our iOS pricing guide for detail.
