We were unable to review the app because it crashed on launch.
Hello, our app gets rejected as it crashes on launch. According to the logs, it happens because the app attempts to access private-sensitive data. We don't collect any of personal data, so it is probably done by Google Firebase embedded in the app (Core, Firestore, Auth). Maybe you have met similar cases and know any of Firebase settings that disable attempts of accessing privacy-sensitive data? We already set FirebaseDataCollectionDefaultEnabled to NO in info.plist, but it still not enough. Maybe error in facebook sdk? Before that it was written that there was an error when starting the ipad air 5 Log1 Log2 Log3

Send UDP Protocol is not working in Xcode 16 iOS18
func setupUDPSocket() { stopSearch() udpSocket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main) do { try udpSocket?.bind(toPort: 4012) try udpSocket?.beginReceiving() try udpSocket?.joinMulticastGroup("239.255.255.250") } catch let error { DispatchQueue.main.async { print(Thread.current) print(error) print(error) } } } private func search() { guard let udpSocket = udpSocket else { print("not set udpSocket") stopSearch() return } let message = "M-SEARCH * HTTP/1.1\r\n" + "HOST: 239.255.255.250:1900\r\n" + "MAN: \"ssdp:discover\"\r\n" + "MX: 3\r\n" + "ST: ssdp:all\r\n" + "\r\n" let data = message.data(using: .utf8)! udpSocket.send(data, toHost: "239.255.255.250", port: 1900, withTimeout: -1, tag: 0) } This is my send SSDP code, my project was inited in Objective-C, recently I update xcode to 16, I get Error Domain=NSPOSIXErrorDomain Code=65 "No route to host", when I send UPD data in iOS 18, but iOS 17 is ok. Even I found, if I init a new project in Swift, this bug is disappear.

Identify what is being dragged globally
I would like to implement the same kind of behavior as the Dropoverapp application, specifically being able to perform a specific action when files are dragged (such as opening a window, for example). I have written the code below to capture the mouse coordinates, drag, drop, and click globally. However, I don't know how to determine the nature of what is being dropped. Do you have any ideas on how to detect the nature of what is being dragged outside the application's scope? Here is my current code: import SwiftUI import CoreGraphics struct ContentView: View { @State private var mouseX: CGFloat = 0.0 @State private var mouseY: CGFloat = 0.0 @State private var isClicked: Bool = false @State private var isDragging: Bool = false private var mouseTracker = MouseTracker.shared var body: some View { VStack { Text("Mouse coordinates: \(mouseX, specifier: "%.2f"), \(mouseY, specifier: "%.2f")") .padding() Text(isClicked ? "Mouse is clicked" : "Mouse is not clicked") .padding() Text(isDragging ? "Mouse is dragging" : "Mouse is not dragging") .padding() } .frame(width: 400, height: 200) .onAppear { mouseTracker.startTracking { newMouseX, newMouseY, newIsClicked, newIsDragging in self.mouseX = newMouseX self.mouseY = newMouseY self.isClicked = newIsClicked self.isDragging = newIsDragging } } } } class MouseTracker { static let shared = MouseTracker() private var eventTap: CFMachPort? private var runLoopSource: CFRunLoopSource? private var isClicked: Bool = false private var isDragging: Bool = false private var callback: ((CGFloat, CGFloat, Bool, Bool) -> Void)? func startTracking(callback: @escaping (CGFloat, CGFloat, Bool, Bool) -> Void) { self.callback = callback let mask: CGEventMask = (1 << CGEventType.mouseMoved.rawValue) | (1 << CGEventType.leftMouseDown.rawValue) | (1 << CGEventType.leftMouseUp.rawValue) | (1 << CGEventType.leftMouseDragged.rawValue) // Pass 'self' via 'userInfo' let selfPointer = UnsafeMutableRawPointer(Unmanaged.passUnretained(self).toOpaque()) guard let eventTap = CGEvent.tapCreate( tap: .cghidEventTap, place: .headInsertEventTap, options: .defaultTap, eventsOfInterest: mask, callback: MouseTracker.mouseEventCallback, userInfo: selfPointer ) else { print("Failed to create event tap") return } self.eventTap = eventTap runLoopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, eventTap, 0) CFRunLoopAddSource(CFRunLoopGetCurrent(), runLoopSource, .commonModes) CGEvent.tapEnable(tap: eventTap, enable: true) } // Static callback function private static let mouseEventCallback: CGEventTapCallBack = { _, eventType, event, userInfo in guard let userInfo = userInfo else { return Unmanaged.passUnretained(event) } // Retrieve the instance of MouseTracker from userInfo let tracker = Unmanaged<MouseTracker>.fromOpaque(userInfo).takeUnretainedValue() let location = NSEvent.mouseLocation // Update the click and drag state switch eventType { case .leftMouseDown: tracker.isClicked = true tracker.isDragging = false case .leftMouseUp: tracker.isClicked = false tracker.isDragging = false case .leftMouseDragged: tracker.isDragging = true default: break } // Call the callback on the main thread DispatchQueue.main.async { tracker.callback?(location.x, location.y, tracker.isClicked, tracker.isDragging) } return Unmanaged.passUnretained(event) } }

Walking speed
I´m working within the health felid with a few apps. Accordingly to science one of the most important parts to keep healthy is every day walking. But it is not to walk slow. You need to come to a little speed (not running or even jogging). But to rais your puls. This is when you get the "real health effect". In general it is around 6km/h. It would be great if apple could make this info available for us developers. I think lots of developers will be happa and use this to make better apps and get more people in a healtheyer life. Looking forward to get some feedback on this. Thank you! Cheers Peter
