An iOS library that obfuscates hard-coded security-sensitive strings to protect them from static analysis.
Obfuscator-iOS is an open-source library for iOS that obfuscates hard-coded security-sensitive strings like API credentials, passwords, and private URLs to prevent them from being easily discovered in the app binary. It works by encoding strings as hexadecimal C arrays during development and dynamically decoding them at runtime, adding a layer of protection against static analysis tools used by attackers.
iOS developers building apps that handle sensitive data, such as those integrating third-party APIs (e.g., Parse, OAuth services) or storing private backend endpoints, and who need to mitigate risks from jailbroken device inspections.
Developers choose Obfuscator-iOS for its simplicity and direct integration into Xcode projects, offering a lightweight yet effective obfuscation method without requiring external services or complex setup, while maintaining compatibility with both Objective-C and Swift.
Secure your app by obfuscating all the hard-coded security-sensitive strings.

Converts plaintext NSStrings into obfuscated C-language hexadecimal arrays, hiding them from static analysis in the app binary without complex encryption.
Uses custom class-based salts to uniquely encode strings, preventing generic deobfuscation attacks and ensuring runtime decoding only with matching salts.
Bridges to Swift projects, allowing use in modern iOS development, as shown in the README's Swift code examples.
Can obfuscate multiple strings at once with automatic salt permutation to maximize success rates, streamlining the process for developers.
Some strings may not obfuscate successfully, requiring manual salt changes or exclusions, as admitted in the README's Step 4 where strings can fail and need retries.
Requires creating Globals files, managing salts, and deleting generation code before deployment, which is error-prone and adds development overhead.
Only obfuscates strings; does not protect against other reverse engineering techniques like runtime debugging or code tampering, offering incomplete security.
