Building a developer tool with Swift? Let us review it.
Expert code review for developer 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.
Developer Tool challenges to solve
Key developer tool concerns that AI-generated code often misses.
Error messages and developer experience
Developers expect error messages that tell them exactly what went wrong, why, and how to fix it. AI-generated tools return generic 'Something went wrong' messages or raw stack traces. Good DX means every error is actionable and every edge case has a helpful response.
API design and consistency
Developer tools live or die by their API surface — whether REST endpoints, CLI arguments, or SDK methods. Naming must be consistent, behavior must be predictable, and breaking changes must be versioned. AI tools generate functional but inconsistent APIs that frustrate developers.
Documentation and examples
Developers won't use your tool if they can't figure it out quickly. You need API reference docs, getting-started guides, code examples in multiple languages, and a changelog. AI tools build the tool but not the documentation ecosystem around it.
Performance and latency
Developer tools are often in the critical path of other developers' workflows — slow API responses, laggy CLIs, or unresponsive dashboards directly waste their time. Every millisecond matters. AI-generated tools have unoptimized database queries and no caching.
What we check
Key areas we review for Swift developer tool projects.
API design — consistent naming, predictable behavior, proper status codes
Error handling — actionable error messages for every failure mode
Authentication — API key generation, rotation, scoped permissions
Rate limiting — per-key limits, usage tracking, quota management

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