Your iOS app was built with AI. Are you sure it works correctly?
41% of code written today is generated by AI. Tools like Cursor, Copilot, Claude Code, Bolt or Lovable let you build apps in hours instead of months. The problem is what you cannot see: security breaches, memory leaks, deprecated APIs, code Apple rejects, and an architecture that collapses when you try to scale.
At AtalayaSoft we audit and fix iOS apps built with vibe coding. Our iOS architect, Francisco José García Navarro, has spent over 12 years working exclusively in native iOS and over 25 years in software development. He has designed architectures for apps with hundreds of millions of users — Zara/Inditex (218M), Banco Santander (15M), AXA, Juegos ONCE. He knows exactly where AIs fail when generating Swift code.
We don't sell fear. We sell certainty. After our audit you will know exactly what problems your app has, which are critical, and how to fix them.
This service is for you if...
You are a CTO or tech lead and your team uses AI to write iOS code
Your team uses Copilot, Cursor or Claude Code daily. Code comes out fast, but nobody reviews what the AI generates with the depth that a production app requires. You worry about security, accumulating technical debt, and Swift Concurrency warnings nobody understands.
You get: A deep technical audit with a severity-prioritised report and a remediation roadmap your team can execute sprint by sprint.
You are a founder, PM or non-technical profile who built your MVP with AI
You built your app with Bolt, Lovable, Cursor or ChatGPT. It works on your iPhone, but you do not know if it is secure, if Apple will approve it, if it will handle real users, or if you are exposing customer data without knowing it.
You get: A clear-language report (no unnecessary jargon) that tells you exactly what is right, what is wrong, and what you need to fix before launching or scaling.
What AI generates and nobody reviews
Security breaches
45% of AI-generated code contains vulnerabilities. In iOS, the most common: API keys hardcoded in source, tokens in unencrypted UserDefaults, HTTPS disabled (NSAllowsArbitraryLoads), and sensitive data stored outside the Keychain.Memory leaks and performance
AIs create retain cycles in closures (forgetting [weak self]), do not cancel Combine subscriptions, launch Tasks that never complete, and place heavy work on the main thread. Result: your app drains battery, freezes and Apple rejects it.Deprecated APIs and obsolete code
AIs generate NavigationView (deprecated since iOS 16), ObservableObject instead of the @Observable macro, foregroundColor() instead of modern alternatives, and completion handlers instead of async/await.App Store rejection
Apple rejects 25% of apps it receives. Most common causes in vibe-coded apps: crashes in untested edge cases, incorrect privacy labels, missing PrivacyInfo.xcprivacy, and minimum functionality (Guideline 4.2).Non-existent accessibility
AI hardcodes font sizes instead of using Dynamic Type, omits accessibilityLabel on icon-only buttons, and creates buttons with onTapGesture() instead of Button. Since June 2025, the European Accessibility Act (EAA) requires apps to be accessible. Fines reach one million euros.Architecture that does not scale
Everything in one file. 500-line views. No layer separation. No tests. No dependency injection. It works for a prototype, but when you need to add features every change breaks something.Vibe coding is fast. The problems it leaves behind, too.

18K users affected when a Lovable app exposed their data (The Register, February 2026). Replit deleted an entire production database ignoring explicit instructions.
What we review in your iOS app
Security
- API keys and secrets hardcoded in source code
- Tokens and credentials stored outside the Keychain
- NSAllowsArbitraryLoads = true (HTTPS disabled)
- Sensitive data in UserDefaults, logs or cache

- Heavy work on the main thread (UI freezes)
- Excessive battery use (location, timers, background)
Architecture
- Layer separation (domain, data, presentation)
- Monolithic files vs. decoupled modules
- Concurrency patterns (legacy GCD vs. async/await)
- Test coverage (unit, UI, snapshot)
- Dependency management and build times
App Store & Compliance
- Privacy labels and PrivacyInfo.xcprivacy correctness
- Privacy policy aligned with actual app behaviour
- Guideline 4.2 (minimum native functionality)
- Required Reason APIs and SDK signatures
- EAA / accessibility compliance (VoiceOver, Dynamic Type)
Native UI & UX
- Correct use of SwiftUI vs. UIKit
- Deprecated APIs (NavigationView, ObservableObject, etc.)
- Dynamic Type vs. hardcoded font sizes
- Accessibility labels, traits and focus order
- Dark mode, iPad and orientation compatibility

The audit cost is deducted if you subsequently engage the fix or team integration service. You do not pay twice.
How the process works
-
01. Send us repository access
Give us access to the repo (GitHub, GitLab, Bitbucket) and tell us the context: which AI tools you used, what the app does, what concerns you. No unnecessary meetings — a form and code access is enough to get started.
-
02. We audit with expert human eyes
We review the code line by line with 11+ years of native iOS experience. We do not use generic automated tools — we use Instruments, Accessibility Inspector, Charles Proxy, and the same profiling stack we use on apps with 218 million users.
-
03. You receive a clear, actionable report
Every problem classified by severity (critical / high / medium / low) with explanation, exact location in the code, and recommended fix. If you are technical, you can execute the roadmap with your team. If not, we walk you through it on the video call.
-
04. We fix and/or integrate into your team
If you choose level 3, we fix directly. If you prefer your team to do it, we guide them. And if you need a senior iOS developer long-term, the natural next step is our team integration service — we already know your codebase better than anyone.
Why AtalayaSoft to audit your iOS code
We are not an automated tool. We are not a web auditor that "also does mobile." We are a studio specialised exclusively in native iOS development since 2019.
Francisco has worked on Zara/Inditex (218M users, 4.8★ on the App Store), Banco Santander (15M users, 4.7★), AXA, El País and Juegos ONCE. He knows how to build an app that handles millions of users because he has done it.
We do not audit React, Flutter or backend. Only native iOS — Swift, SwiftUI, UIKit, and everything Apple requires to approve and maintain an app on the App Store.
We use Claude Code every day as a development tool. We know exactly what patterns AI generates, where it goes wrong, and how to fix it. We are not against AI — we are in favour of code that works.
What AI does wrong in Swift (that you cannot see)
For CTOs and tech leads who want to understand the specific technical patterns we look for:
NavigationView instead of NavigationStack
Deprecated since iOS 16. AI uses it because it has more examples in its training data.
ObservableObject + @Published instead of @Observable
The @Observable macro (iOS 17+) is more efficient and simpler. AI generates the old pattern by default.
DispatchQueue.main.async instead of @MainActor
When AI encounters concurrency errors, it falls back to GCD instead of using the modern actor system.
Computed properties in views instead of sub-views
Breaks @Observable optimisation and creates views that are impossible to reuse.
onTapGesture() instead of Button
Breaks VoiceOver, eye tracking on visionOS, and standard iOS haptic feedback.
font(.system(size: 17)) instead of .body
Hardcoding font sizes breaks Dynamic Type and violates the EAA.
Closures with strong self in Tasks
Retain cycles that cause invisible memory leaks until the app runs out of RAM.
Everything in one file
Slow builds, impossible merges, and zero possibility of unit testing.
Apps where we have worked at production scale
We are not theoretical auditors. We have built and maintained iOS apps with hundreds of millions of users. That experience is what allows us to identify problems that an automated tool cannot see.
