What the iOS Architecture Audit is

Most iOS startups reach a point where the codebase has outgrown its original design. Features slow down. Engineers work around old decisions instead of building forward. The audit finds those constraints before they get worse — and before you hire a larger team to work around them at scale.

The service is a fixed-scope, asynchronous-first engagement. You grant read-only repository access, complete a short intake form, and receive a written technical report on day 5. No long discovery calls. No open-ended retainer. One senior-level engineer reviews your full system and delivers a structured, prioritized report with a live walkthrough.

The audit is not a generic checklist. Every finding maps to your specific codebase and is cross-referenced against SwiftData, CloudKit, and Apple's App Privacy Details requirements — the same constraints you ship under.

What the audit covers

System architecture

Layer separation, module boundaries, dependency direction, and structural patterns that create coupling or scaling bottlenecks.

Data layer and sync strategy

Core Data or SwiftData schema design, CloudKit sync, conflict resolution, and local-first vs cloud-first tradeoffs that affect scalability.

Core ML and AI-native readiness

Whether the codebase can support on-device inference without a structural rewrite — model storage patterns, background processing, and Foundation Models API compatibility.

Performance and memory

Instruments-based profiling to identify main-thread blocking, memory pressure, launch latency, and Neural Engine utilization gaps.

App Store compliance

Static review of signing configuration, entitlements, target structure, and Review Guidelines risk areas before they cause a rejection cycle.

Codebase structure

File organization, naming patterns, test coverage gaps, and anything that slows feature development or makes onboarding harder than it needs to be.

Deliverables

  • Written technical report with findings prioritized as Critical / Warning / Advisory
  • Prioritized architectural roadmap with specific, actionable next steps
  • AI-native readiness summary — on-device vs cloud tradeoff analysis for your specific app
  • App Store compliance risk notes with reference to exact guideline sections
  • 90-minute live walkthrough session to discuss findings and answer questions

How it works — 5 days

Day 1

Access and intake

You grant read-only repository access and complete a short async intake form. No calls required. The review begins immediately.

Day 2

Architecture and data layer review

System architecture, SwiftUI view hierarchy and state management, data schema, sync strategy, and layer separation reviewed against production iOS engineering standards.

Day 3

AI readiness and performance profiling

On-device AI integration assessment with Core ML and Foundation Models criteria. Instruments profiling for performance, memory, and Neural Engine utilization.

Day 4

App Store compliance and codebase structure

Signing, entitlements, target dependencies, Review Guidelines risk areas, and overall codebase organization assessed and documented.

Day 5

Report delivery and 90-minute walkthrough

Full written report with prioritized findings delivered. Live session walks through each issue, implementation options, and the recommended next steps.

Who this is for

The iOS Architecture Audit is designed for teams that already have a codebase and need clarity on where it can go. The typical client is a funded startup that shipped a working iOS app and is now preparing to scale the team, add AI features, or raise their next round.

Good fit

  • Funded startups with an existing iOS or macOS codebase
  • Teams planning to add on-device AI or Core ML features
  • Products preparing to scale the engineering team
  • Apps with performance, sync, or architectural debt issues
  • Pre-acquisition or pre-investment technical due diligence
  • Founders who want an honest second opinion on technical decisions

Not a fit

  • Idea stage with no existing code — start with the MVP Sprint
  • Looking for ongoing hourly code reviews or consulting
  • React Native or cross-platform projects
  • Projects looking for the cheapest option available

Common questions

Does my iOS app need to be live on the App Store?
No. The audit only requires an existing codebase. Pre-launch products benefit most — fixing structural issues before they're embedded in multiple features is significantly cheaper than fixing them later. Post-launch apps benefit when facing performance, scaling, or AI integration challenges.
What do you need from me to start?
Read-only repository access (GitHub, GitLab, or Bitbucket) and a short async intake form covering product context, known issues, and target Apple platforms (iOS, iPadOS, macOS). No discovery call required — the audit starts the same day access is granted.
What is AI-native readiness assessment?
It checks whether your architecture can add on-device AI features without a structural rewrite. The assessment covers data model compatibility with Core ML output storage, background processing patterns for inference, Foundation Models API requirements, and deployment target constraints for the AI features you want to ship.
How is this different from a standard code review?
A code review examines individual lines and patterns. An architecture audit evaluates the system as a whole: how layers interact, where data flows, and how decisions in one layer constrain future work elsewhere. The deliverable is a prioritized roadmap with structural recommendations — not a list of code comments.
Can you audit a React Native or Flutter app?
No. The audit is specifically designed for native Apple platform codebases — Swift, SwiftUI, UIKit, Core Data, SwiftData, and the supporting Apple frameworks. Cross-platform projects are out of scope.
