I have a third party app for controlling Sony mirrorless cameras over WiFi. I’m really excited to integrate the new camera controls on the iPhone 16 Pro with the app. I’ve found the documentation around this, and seems I need an AVCaptureSession setup in order to utilise them. func configureControls(_ controls: [AVCaptureControl]) { // Verify the host system supports controls; otherwise, return early. guard captureSession.supportsControls else { return } // Begin configuring the capture session. captureSession.beginConfiguration() // Remove previously configured controls, if any. for control in captureSession.controls { captureSession.removeControl(control) } // Iterate over the passed in controls. for control in controls { // Add the control to the capture session if possible. if captureSession.canAddControl(control) { captureSession.addControl(control) } else { print("Unable to add control \(control).") } } // Commit the capture session configuration. captureSession.commitConfiguration() } can I just use a freshly initialised capture session for this? Or does it need to be configured in any other ways? Are there any down sides to creating a session (CPU usage etc) that I may experience from this? Also, the scope of the controls is quite narrow. For something like shutter speed or aperture that has quite a number of possible values but requires custom labels, and a non-linear scale (so the AVCaptureIndexPicker seems to be the way to go). Will that picker support enough values to represent something like shutter speed or aperture? Is there any chance we may get non-linear float based controls in the future, which may feel more natural from a UX perspective than index-based? Apologies, lots of edits going on here as I think about this more. Is there any way, or would any way be considered of putting these controls in a disabled state like with other UI elements in iOS? There are times (during capture for example) that a lot of these settings can be unavailable (as communicated by the Sony camera) to be changed by the user, and managing a queue of changes when the function is unavailable to be set is going to be a challenge. If there won’t be, how will they behave if controls are removed whilst being interacted with? Presumably they will disappear entirely from the UI? Thanks!

As of iOS 18.1 being released we are having issues with our users experiencing issues with our app that relies on strobing the device torch. We have narrowed this down to being caused on devices with adaptive true-tone flash and have submitted a radar: FB15787160. The issue seems to be caused by ambient light levels. If run in a dark room, the torch strobes exactly as effectively as in previous iOS versions, if run in a light room, or outdoors, or near a window, the strobe will run for ~1s and then the torch will get stuck on for half a second or so (less frequently it gets stuck off) and then it will strobe again for ~1s and this behaviour repeats indefinitely. If we go to a darker environment, and background and then foreground the app (this is required) the issue is resolved, until moving to an area with higher ambient light levels again. We have done a lot of debugging, and also discovered that turning off "Auto-Brightness" from Settings -> Accessibility -> Display & Text Size resolves the issue. We have also viewed logs from Console.app at the time of the issue occurring and it seems to be that there are quite sporadic ambient light level readings at the time at which the issue occurs. The light readings transition from ~100 Lux to ~8000 Lux at the point that the issue starts occurring (seemingly caused by the rear sensor being affected by the torch). With "Auto-Brightness" turned off, it seems these readings stay at lower levels. This is rendering the primary use case of our app essentially useless, would be great to get to the bottom of it! We can't even really detect it in-app as I believe using SensorKit is restricted to research applications and requires a review process with Apple before accessing? Edit: It's worth noting this is also affecting other apps with strobe functionality in the exact same way
