Building a internal tool with Swift? Let us review it.
Expert code review for internal tools 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.
Internal Tool challenges to solve
Key internal tool concerns that AI-generated code often misses.
Access control
Who can see what? Internal tools need role-based access — finance sees revenue data, support sees customer data, engineering sees system metrics. AI tools build the dashboard but rarely implement granular permissions.
Data sensitivity
Internal tools often connect directly to production databases. A bug that deletes records or a missing auth check that exposes customer PII can have serious legal and business consequences.
Network security
Internal tools should be behind a VPN or protected network, not on the public internet. AI tools deploy to public URLs by default. Proper network configuration prevents external access.
Audit logging
When someone modifies data through an internal tool, you need to know who did what and when. This is essential for debugging, compliance, and accountability.
What we check
Key areas we review for Swift internal tool projects.
Access control — role-based permissions enforced server-side
Database security — read-only where possible, protected write operations
Network configuration — not publicly accessible, VPN or auth gateway
Audit logging — who did what, when

Frequently asked questions
Can you review a internal tool built with Swift?
Yes. We regularly audit Swift internal tool 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 internal tools?
Common issues include force unwrapping optionals and storing secrets in userdefaults on the Swift side, combined with internal tool-specific concerns like access control and data sensitivity. We check for all of these and more.
How do I make my Swift internal tool production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Swift internal tool projects, the typical path is: fix security gaps, address internal tool-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 internal tool?
Our code audit delivers a full report within 24 hours. For Swift internal tool projects, we check security, architecture, performance, and deployment readiness across all Swift-specific patterns. Fixes are scoped separately with a fixed quote.
