How to Protect OpenAI API Key in Swift iOS Applications

Native iOS & Swift Proxy for OpenAI Chat & Embeddings

Direct Answer & Architecture Summary

Never embed OpenAI keys in iOS app bundles or Info.plist files; tools like strings, Ghidra, and Hopper easily extract constants. Call RealComposer from Swift URLSession to inject keys on Cloudflare Workers.

The Problem Solved

iOS App Constants Are Easily Decompiled

Compiling an iOS IPA does not encrypt string literals; any jailbroken device or tool can dump memory and string tables.

Critical Security & Operational Risks:

Instant API key extraction using strings command on binary
Unlimited model access at your expense
