Building a mvp / prototype with Swift? Let us review it.
Expert code review for mvp / prototype apps built with Swift. We fix Swift-specific security gaps, optimize performance, and handle deployment. From $19.
Common Swift issues we find
Real problems from Swift codebases we've reviewed.
Force unwrapping optionals
Using ! to force-unwrap optionals instead of guard let or if let, causing runtime crashes when values are nil.
Storing secrets in UserDefaults
Saving API keys, tokens, and passwords in UserDefaults (plaintext plist) instead of Keychain, making them easily extractable from device backups.
Retain cycles from closures
Strong references to self inside closures and delegate patterns without [weak self] or [unowned self], causing memory leaks that grow over app lifetime.
Main thread blocking
Network requests, file I/O, and heavy computation performed on the main thread, freezing the UI and risking watchdog termination.
MVP / Prototype challenges to solve
Key mvp / prototype concerns that AI-generated code often misses.
Identifying what actually needs fixing
Not everything needs to be production-grade for an MVP. The challenge is knowing which shortcuts are acceptable (visual polish, advanced features) and which aren't (security, data loss, broken core flows). Our audit prioritizes fixes by impact.
Security minimum
Even an MVP handles user data. You need authentication that works, data isolated per user, no exposed secrets, and HTTPS. You don't need enterprise-grade security, but you need the basics done right.
Deployment
Your app runs locally but deploying it involves environment variables, domain configuration, SSL, and build optimization. First-time deployment is where most AI prototypes hit unexpected issues.
Error handling
When something goes wrong (and it will), your users should see a helpful message — not a white screen or a raw error. Basic error handling is the difference between 'this app is buggy' and 'something went wrong, please try again.'
What we check
Key areas we review for Swift mvp / prototype projects.
Core user flow — does signup to core action work reliably?
Authentication — secure login, session handling, password reset
Data security — user data isolation, no exposed secrets
Deployment readiness — env vars, build configuration, domain setup
Not sure if your app passes? Our code audit ($19) checks all of these and more.

Frequently asked questions
Can you review a mvp / prototype built with Swift?
Yes. We regularly audit Swift mvp / prototype projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in Swift mvp / prototype apps?
Common issues include force unwrapping optionals and storing secrets in userdefaults on the Swift side, combined with mvp / prototype-specific concerns like identifying what actually needs fixing and security minimum. We check for all of these and more.
How do I make my Swift mvp / prototype production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Swift mvp / prototype projects, the typical path is: fix security gaps, address mvp / prototype-specific requirements, optimize Swift performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a Swift mvp / prototype?
Our code audit delivers a full report within 24 hours. For Swift mvp / prototype projects, we check security, architecture, performance, and deployment readiness across all Swift-specific patterns. Fixes are scoped separately with a fixed quote.
