End-to-end on iOS sim: UIKitPlatform boots an SxAppDelegate, installs an SxGLView (UIView subclass overriding +layerClass to return CAEAGLLayer) as the root view controller's view, sets the drawable properties (EAGLColorFormatRGBA8, non-retained backing — looked up by dlsym so pointer-identity-checked constants match), creates an EAGLContext (GLES3), and registers a CADisplayLink that invokes the user's frame closure on every vsync. end_frame presents the renderbuffer via [EAGLContext presentRenderbuffer:]. The renderbuffer is allocated lazily in -[SxGLView layoutSubviews] once the layer has its real on-screen bounds — allocating earlier (e.g. in didFinishLaunching) failed with INCOMPLETE_ATTACHMENT because the SxGLView's frame was still zero at that point. Setting the SxGLView as the VC's `view` (via setView:) lets the standard VC layout pipeline size it to the window without us having to read CGRect struct returns from objc_msgSend. EAGL drawableProperties dict keys/values are dlsym'd from OpenGLES — the framework checks them by pointer identity, so synthesized NSString literals with the same contents don't work. examples/66-uikit-platform.sx — runnable smoke test that cycles the screen color (red → green → blue every 30 frames) so you can confirm the display-link tick and present pipeline. modules/opengl.sx gains glGenFramebuffers, glGenRenderbuffers, glBindFramebuffer, glBindRenderbuffer, glFramebufferRenderbuffer, glGetRenderbufferParameteriv, glCheckFramebufferStatus — needed for the iOS GLES FBO-to-renderbuffer setup. They're wired into load_gl so SDL and the iOS dlsym loader both pick them up. Compiles cleanly on macOS / WASM / iOS-sim. Non-iOS targets never reference the unresolved UIKit/QuartzCore/OpenGLES symbols because every Obj-C touch lives inside `inline if OS == .ios`. Game's iOS path still goes through SDL3 for now. Touch events + game wire-up + keyboard observer = next steps.
