I have a C++ project I've been working on fine in XCode 9, where when I edit a header file it automatically detects which object files need to be recompiled when I go to build/run the program. As of XCode 10.0 (10A255), however, when I make edits to my header files, XCode doesn't detect the changes and doesn't recompile anything when I try to build/run. So I have to clean the entire build folder and rebuild everything any time I make changes to a header file. Anyone else have this issue?

I'm trying to make an iOS app where the user can adjust the exposure manually (I'm using a single slider to adjust ISO and shutter speed at the same time). It mostly works fine, however when I adjust these values, I can tell iOS is doing an additional tone mapping step to try to equalize the pixel values, and it messes with the exposure (for example, really brightening up dark pixels when I might actually want them dark). I've tried everything I can see in the documentation to disable this extra tone mapping step, but none of these successfully disable it (I'm testing using an iPhone 8 with iOS 13.3.1). Any ideas what else I can do to disable this effect and get unmodified pixels?camera = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .back) if (camera.isLowLightBoostSupported) { camera.automaticallyEnablesLowLightBoostWhenAvailable = false; } if (camera.activeFormat.isGlobalToneMappingSupported) { camera.isGlobalToneMappingEnabled = false; } camera.automaticallyAdjustsVideoHDREnabled = false; if (camera.activeFormat.isVideoHDRSupported) { camera.isVideoHDREnabled = false; }
