Hello friends I’m currently developing an iOS application that uses the attitude from CoreMotion. For this I need to evaluate the specific values of Pitch, Roll and Yaw. As long as the app is in landscape mode and the device upright (X-axis up), I only need some small adjustments of the values to get the right attitude data. New: Pitch -> Y-axis, Yaw -> X-axis and Roll = Z-axis. func startDeviceMotion() { if motionManager.isAccelerometerAvailable { self.motionManager.deviceMotionUpdateInterval = self.interval self.motionManager.showsDeviceMovementDisplay = true self.motionManager.startDeviceMotionUpdates(using: .xTrueNorthZVertical) // Configure a timer to fetch the motion data self.timer = Timer(fire: Date(), interval: self.interval, repeats: true, block: { (timer) in if let motion = self.motionManager.deviceMotion { // write the values my own orientation data structure self.orientation.azimuthAngle = Measurement(value: -motion.attitude.yaw, unit: UnitAngle.radians) self.orientation.inclinationAngle = Measurement(value: -motion.attitude.roll-(Double.pi/2.0), unit: UnitAngle.radians) self.orientation.bankAngle = Measurement(value: motion.attitude.pitch, unit: UnitAngle.radians) } }) // Add the timer to the current run loop. RunLoop.current.add(self.timer!, forMode: RunLoop.Mode.default) } } However, when I use it in portrait mode (Y-axis up), I can't find a suitable conversion that provides me good values. Most of the time I get mixed values. The goal is that the following axes define Pitch, Roll and Yaw. Pitch -> X-axis, Yaw -> Y-axis, Roll -> Z-axis Has anyone ever had this problem and could explain how to get meaningful pitch, roll and yaw values with an iPad in portrait mode? Kind regards

Hello Friends I am currently developing a framework that offers a SwiftUI menu among other things. In this menu I use a normal FileImporter. import SwiftUI import UIKit import UniformTypeIdentifiers struct SimulatorConnectionView: View { @State private var isImporting: Bool = false @State private var fileSelected: Bool = false @State private var filename: String = "Select File" @State private var url: URL = URL(string: "/")! var body: some View { VStack{ // some code HStack { StandardButton(title: filename, width: 250, locked: false, action: { isImporting = true }) } // some code }.fileImporter( isPresented: $isImporting, allowedContentTypes: [UTType.text], allowsMultipleSelection: false ) { result in do { guard let selectedFile: URL = try result.get().first else { return } url = selectedFile fileSelected = true filename = selectedFile.lastPathComponent } catch { // Handle failure. print(error.localizedDescription) } } } } I’m using XCode 14.3.1 and I’m building for an iPad Air (4. Gen) with iOS 16.2 When I now run the application that uses the framework and open the FileImporter, the standart window opens. But after a certain time, it starts to flicker and eventually crashes. The following Error Message occurs: 2023-08-29 09:36:37.652586+0200 “MyApplication” [2161:397002] [lifecycle] [u 8130AA3A-2C68-4F54-91D0-9CA032B2644F:m (null)] [com.apple.DocumentManagerUICore.Service(1.0)] Connection to plugin interrupted while in use. 2023-08-29 09:36:37.654256+0200 “MyApplication” [2161:397002] [lifecycle] [u 8130AA3A-2C68-4F54-91D0-9CA032B2644F:m (null)] [com.apple.DocumentManagerUICore.Service(1.0)] Connection to plugin invalidated while in use. 2023-08-29 09:36:37.663598+0200 “MyApplication” [2161:396793] [DocumentManager] The view service did terminate with error: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted} 2023-08-29 09:36:37.663672+0200 “MyApplication” [2161:396793] [DocumentManager] Remote view controller crashed with error: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted}.

Has maybe someone an idea what the problem could be or can give me at least a hint in which direction I have to search? Kind regards
