  1. Hi everyone, I’m currently working on an ESP mod for Call of Duty: Mobile (iOS). It’s injected as a .dylib using Theos and tested both on jailbroken devices (Dopamine, iOS 15.6) and non-jailbroken (ESign-compatible). ✅ What’s working: I’m hooking -[UIViewController viewDidLayoutSubviews] using MSHookMessageEx I successfully locate the MTKView dynamically inside the view hierarchy The CAMetalLayer, nextDrawable, MTLCommandQueue, MTLCommandBuffer, and encoder are all valid I call DrawESP() using ImGui::GetBackgroundDrawList()->AddRect(...) with visible screen coordinates The code proceeds through ImGui::Render() and ImGui_ImplMetal_RenderDrawData(...) commandBuffer presentDrawable + commit runs with no errors ✅ Logs confirm everything is called and completed without crash ❌ The issue: Nothing shows on screen. No ESP boxes, no ImGui UI, no crashes either. Even though everything executes cleanly and logs indicate correct flow, nothing appears visually. 🔍 Already checked: The MTKView is properly attached to a visible UIViewController and active on screen The memory reads (EntityList, LocalPlayer, etc.) return valid data – confirmed from game dumps and offset analysis No UIView or UIKit overlay is interfering (this is pure Metal rendering using ImGui) Device is stable, and logs confirm correct Metal context ❓ What I need help with: Has anyone here successfully displayed ImGui or ESP overlays inside COD Mobile iOS using a CAMetalLayer or MTKView? Do I need to hook into a deeper rendering function, like RenderScene() inside CODM’s game engine, for it to actually draw to screen? 🧠 Setup: iPhone 11, iOS 15.6, Dopamine jailbreak Injection via Theos (no Logos, full ObjC++) Compatible with ESign for non-jailbreak testing Using imgui_impl_metal.mm backend (latest from GitHub) Any help or suggestions would be greatly appreciated 🙏 If you have experience with ImGui rendering on CODM iOS, or know which engine-level method to hook, please share! Thanks in advance!
