iOS – Advanced Reskin of SwiftUI Audio Template + App Store Submission
Budget: $2,000 – $3,000 USD
We need an experienced iOS (Swift/SwiftUI) developer to perform an advanced reskin of an existing audio template and prepare a clean App Store submission. This is not a cosmetic repaint; we expect production-grade refactors, Apple compliance, and a premium UX polish.
Scope & key tasks
UI/UX overhaul (SwiftUI): premium look & feel, smooth navigation, haptics, micro-animations, dark mode, dynamic type, VoiceOver checks.
Audio layer (AVFoundation/AVAudioEngine): reliable multi-track mixing, per-track volume, background audio, interruption handling, route changes (AirPods/Bluetooth), performance tuning; local caching of audio files with safe fallbacks if Firebase is slow/offline.
Template integration: keep Firebase content model (images/sounds hosted remotely), preserve “favorites” local storage, maintain premium flags driven from remote config/JSON.
Monetization: replace one-time IAP framework with StoreKit 2 + RevenueCat (monthly/annual, optional lifetime), paywall, restore purchases, sandbox/test plans.
Analytics & crash reporting: Firebase Analytics + Crashlytics; minimal event map (play, stop, mix change, paywall view, purchase).
Networking & caching: image/audio caching, retry/backoff, reachability, safe decoding.
Ads (optional toggle): keep AdMob wiring but fully feature-flagged (build-time & remote), ensuring no policy conflicts with IAP.
App quality & compliance: Apple HIG, App Store Review Guidelines (background audio usage, privacy), App Privacy nutrition labels, ATT where applicable, clean Info.plist, correct entitlement usage.
Build & release: TestFlight pipeline, provisioning, app icons/splash, localized strings scaffolding (EN ready), submission-ready build with review notes.
Deliverables
Fully reskinned SwiftUI app (Xcode 15+/iOS 16+) with premium UI and smooth navigation.
Audio engine stable for multi-track playback/mixing, background mode, and interruptions.
Subscriptions via RevenueCat (monthly/annual, restore, intro offers if allowed).
Firebase integration (Auth optional), remote content, analytics/crash reporting.
TestFlight build + submission package (screenshots guidelines, review text, privacy labels).
Short technical handover (README: architecture, config, keys, test accounts).
Must-have skills
Swift/SwiftUI 5–6, AVFoundation/AVAudioEngine, concurrency (async/await), Combine.
StoreKit 2 + RevenueCat on production apps.
Firebase (Remote data, Storage/Hosting, Analytics, Crashlytics).
Strong App Store submission track record (links required).
Nice to have
Experience optimizing audio latency & CPU/memory footprint.
Feature-flag frameworks; Xcode Cloud/TestFlight automation.
What we provide
Licensed template code, branding assets, audio/image packs, Firebase project.
Wireframe references for premium reskin.
Timeline & budget
MVP/TestFlight within 20–35 days.
Proposal requirements
3–5 App Store links to SwiftUI apps you shipped (ideally with subscriptions + audio).
5–8 lines on how you’ll replace the template’s one-time IAP with RevenueCat subscriptions (entitlements, offerings, sandbox, edge cases).
5–8 lines on your audio stack (AVAudioEngine graph, session category, interruptions, caching).
