Senior iOS Developer (Objective-C/C++) for App Runtime Stability & Sandbox Analysis
Budget: €250 – €750 EUR
I am looking for an experienced iOS Systems Developer to create a custom runtime module (dylib) for a personal research project on iOS 16 (Rootless environment).
The Challenge: I have a specific application that crashes or refuses to launch when running in a developer/debug environment due to rigorous environment checks (file system integrity, dynamic library injection checks, sysctl flags).
Requirements:
Deep understanding of Theos, Logos, and Objective-C runtime.
Experience with low-level system hooks (access, stat, sysctl, dyld).
Ability to implement a "Whitelist" approach for file system access (masking non-system files).
Experience handling SVC (Supervisor Call) instructions is a massive plus.
Deliverables:
Source code (Tweak.x / Makefile).
Compiled .deb file compatible with ElleKit/Substrate.
Note: This is for local QA testing on my own device to resolve stability issues. Please only bid if you understand iOS internal architecture.
