Reply to CMMotionManager incorrect behavior
Hi,I'm also having issues with CMMotionManager and iOS 10. Running the same code on iOS 9, the data (and my visualization) is very stable (I'm using the CMAttitudeReferenceFrameXMagneticNorthZVertical reference frame) but with iOS 10, it's jittery.So far I couldn't find any documentation or WWDC videos that would point me towards API changes in CoreMotion.framework. So this seems to be an internal framework problem.

Mac Studio: Continuity Camera unavailable after reboot unless USB camera is connected
Summary On Mac Studio systems (no built-in camera), macOS does not initialize camera services after a normal reboot if no physical camera is present. As a result, Continuity Camera does not appear anywhere in the system. Observed behavior System Information → Camera reports “No video capture devices were found.” Continuity Camera (iPhone) is completely absent from camera lists. Plugging in any USB UVC webcam immediately initializes camera services and causes both the USB camera and the iPhone (Continuity Camera) to appear. The USB camera can then be unplugged and Continuity Camera continues working until the next reboot. Reproduction steps Use a Mac Studio (no built-in camera) on recent macOS. Ensure no USB webcam or external camera is connected. Reboot the Mac normally. After login, open System Information → Camera. Expected Camera services should initialize even when no physical camera is present, allowing Continuity Camera to be available as the primary camera. Actual No camera devices ar

I am having trouble running a Xamarin iOS Application in an iOS Simulator on my Mac
Whenever I attempt to build and run my Xamarin iOS app from within Visual Studio for Mac, I get this error message after a failed build: /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.Shared.targets(3,3): Error: Could not find any available provisioning profiles for MyProject on iOS. I understand that provisioning profiles ought to be required only when I am trying to run my application on a real iOS device. I am not trying to run the application on a real iOS device, I am trying to run this on an iOS simulator. I do setup my publishing profile in both Visual Studio and Xcode with my Apple Developer account - which is linked to my company's team account. But this does not resolve the issue. Is anyone else experiencing something like this? I'd appreciate any help on this issue.

Reply to USB hub failing under Monterey
I have this same issue on an M2 Max Studio running Ventura 13.6. I have an apple keyboard and trackpad connected via lightning<->USB-A to a KVM, and then via USB-A to the Mac Studio. The trackpad will move the mouse pointer around, but dies as soon as you click the keypad. I then moved the KVM output to a USB-A<->USB-C adapter, and plugged it into the USB-C port on the Mac studio, and it mostly works okay now, but the connection will lock up intermittently and I have to unplug the connection to the Mac studio, and plug it back in again. This typically happens after returning from screen saver, but I've had it happen before under normal active operation. I had this exact same connection set up previously with a Mac Mini (2014) and it never gave me these sorts of issues with the I/O ports.

Reply to Image Miniaturization Issue
Mr. Gemini who works for Google, Inc. says the following about 'iOS 26 image shrunken to 4 x 4.' Reports of images being shrunken to 4x4 in iOS 26 refer to a visual glitch that some users experienced, which was caused by new features like CarPlay's Smart Display Zoom. This was not an intended feature of the new software, and Apple quickly addressed the issue. Here's an explanation of what happened: A new OS feature caused a visual glitch. With the release of iOS 26 in September 2025, some users reported that photos would be displayed as extremely small, 4x4 pixel images. The bug was tied to CarPlay. This issue appeared when using CarPlay and was related to a new setting called Smart Display Zoom. Disabling this feature could resolve the problem for some users. Apple fixed it in a software update. The visual bug was never widespread and was resolved by Apple in the early 26.0.1 update, which was released just a few days after the initial public launch. The

Reply to MacBook Pro freezing after inactivity
I'm having this exact issue with my MacBook Pro Early 2015 in Catalina beta 5. I haven't been able to figure out what exactly causes it, but after a few minutes of not interacting with the computer, the trackpad can no longer be clicked, keyboard doesn't appear to work, and the display freezes. The only option is to hold the power button to restart.Each of the 3 times this has happened I've been running Safari, the latest Xcode beta (5) + simulator, Music, Terminal, Sketch, and Visual Studio Code. On AC power, with iPhone connected via USB. I haven't been able to duplicate the freezing in Safe Mode.Edit: Just tested again. I disabled screensaver to see if it had any effect, and it still froze exactly 6 minutes and 8 seconds after I left it alone.Edit 2: Again: 6 minutes, 17 seconds.Edit 3: Unplugged power. 18+ minutes, no freeze.

I'm getting the same thing when I try to upload a build to ASC. I've had bitcode disabled for a long time and have had no problem making builds as recently as last week.

Reply to UIVisualEffectView with mask doesn’t blur in iOS 10
On iOS 10 blurs can't sample content through a mask – because you make the visual effect view a subview of a view with a mask you prevent it from sampling the content it needs to do the masking.You need to apply the mask *directly* to the UIVisualEffectView, not to a superview. This works on iOS 11 due to improvements specifially made on that OS version.

Storyboard file won't update visually
Whenever I change somehting in a .storyboard file it won't update visually.Examples:- If I change a constraints constant value it doens't update (and it doesn't turn yellow or red or anything)- If I delete a view it looks like it's still there although I can't select it anymore- If I move a UILabel it looks like it didn't move, but I can only select it again in the position I moved it toIf I restart Xcode then the UI is updated. I've tried the latest Xcode version and the 11.5 Beta version too. I've tried rebooting the computer, cleaned build folders, derived data and reinstalling the command line tools.UPDATE: I realized that only ONE view controller is bugged, all the others update normally.

Reply to Greetings, I have two questions: Can i upload an app on both the app store and google play? and if so how can i do it?
Take a look at RoboVM which allows you to write iOS applications in Java, the end-result is converted to the same bytecode that is created when you write the application using Objective-C or Swift. RoboVM has it's own IDE called RoboVM Studio, which is a fork of IntelliJ (Same as the Android SDK IDE)

Reply to Where is the living auto-layout guide now located?
I found this :h ttps://developer.apple.com/design/human-interface-guidelines/ios/visual-design/adaptivity-and-layout/but it then links to the Archive.So may be the answer is that the document does not exist anymore except in Archive. It is worth nArchiving as a developer's document !
