For the last two weeks Time Machine has been unable to complete back up. It's throwing up the following: The error detail shows : The file does not exist in finder and have tried logging Mac out of iCloud and back in again but error remains. Any thoughts much appreciated.

hello everybody, I have a new idea for the future a new product the new iPod with integrated mobile router and with more functions also other products in this category more functions you can thinking for gaming and more one function is special for handheld controller. One is Nintendo Switch or other consoles. She have problem with the Wi-Fi. When you most login we are website. This problem is with this problem. Not more a problem. This is the idea one from thousand ideas the best is the software you can use this for working and for the children for the first smartphone you cannot calling all person you can only call the 911 or the family interest you making with FaceTime this is the number one for communication on this iPod. This is a new category and you can music streaming.

I have an app that was written in UIKit. It's too large, and it would be much too time consuming at this point to convert it to SwiftUI. I want to incorporate the new limited contacts into this app. The way it's currently written everything works fine except for showing the limited contacts in the contact picker. I have downloaded and gone though the Apple tutorial app but I'm having trouble thinking it through into UIKit. After a couple of hours I decided I need help. I understand I need to pull the contact IDs of the contacts that are in the limited contacts list. Not sure how to do that or how to get it to display in the picker. Any help would be greatly appreciated. func requestAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) { switch CNContactStore.authorizationStatus(for: .contacts) { case .authorized: completionHandler(true) case .denied: showSettingsAlert(completionHandler) case .restricted, .notDetermined: CNContactStore().requestAccess(for: .contacts) { granted, error in if granted { completionHandler(true) } else { DispatchQueue.main.async { [weak self] in self?.showSettingsAlert(completionHandler) } } } // iOS 18 only case .limited: completionHandler(true) @unknown default: break } } // A text field that displays the name of the chosen contact @IBAction func contact_Fld_Tapped(_ sender: TextField_Designable) { sender.resignFirstResponder() // The contact ID that is saved to the Db getTheCurrentContactID() let theAlert = UIAlertController(title: K.Titles.chooseAContact, message: nil, preferredStyle: .actionSheet) // Create a new contact let addContact = UIAlertAction(title: K.Titles.newContact, style: .default) { [weak self] _ in self?.requestAccess { _ in let openContact = CNContact() let vc = CNContactViewController(forNewContact: openContact) vc.delegate = self // this delegate CNContactViewControllerDelegate DispatchQueue.main.async { self?.present(UINavigationController(rootViewController: vc), animated: true) } } } let getContact = UIAlertAction(title: K.Titles.fromContacts, style: .default) { [weak self] _ in self?.requestAccess { _ in self?.contactPicker.delegate = self DispatchQueue.main.async { self?.present(self!.contactPicker, animated: true) } } } let editBtn = UIAlertAction(title: K.Titles.editContact, style: .default) { [weak self] _ in self?.requestAccess { _ in let store = CNContactStore() var vc = CNContactViewController() do { let descriptor = CNContactViewController.descriptorForRequiredKeys() let editContact = try store.unifiedContact(withIdentifier: self!.oldContactID, keysToFetch: [descriptor]) vc = CNContactViewController(for: editContact) } catch { print("Getting contact to edit failed: \(self!.VC_String) \(error)") } vc.delegate = self // delegate for CNContactViewControllerDelegate self?.navigationController?.isNavigationBarHidden = false self?.navigationController?.navigationItem.hidesBackButton = false self?.navigationController?.pushViewController(vc, animated: true) } } let cancel = UIAlertAction(title: K.Titles.cancel, style: .cancel) { _ in } if oldContactID.isEmpty { editBtn.isEnabled = false } theAlert.addAction(getContact) // Select from contacts theAlert.addAction(addContact) // Create new contact theAlert.addAction(editBtn) // Edit this contact theAlert.addAction(cancel) let popOver = theAlert.popoverPresentationController popOver?.sourceView = sender popOver?.sourceRect = sender.bounds popOver?.permittedArrowDirections = .any present(theAlert,animated: true) } func requestAccess(completionHandler: @escaping (_ accessGranted: Bool) -> Void) { switch CNContactStore.authorizationStatus(for: .contacts) { case .authorized: completionHandler(true) case .denied: showSettingsAlert(completionHandler) case .restricted, .notDetermined: CNContactStore().requestAccess(for: .contacts) { granted, error in if granted { completionHandler(true) } else { DispatchQueue.main.async { [weak self] in self?.showSettingsAlert(completionHandler) } } } // iOS 18 only case .limited: completionHandler(true) @unknown default: break } } // MARK: - Contact Picker Delegate extension AddEdit_Quote_VC: CNContactPickerDelegate { func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) { selectedContactID = contact.identifier let company: String = contact.organizationName let companyText = company == "" ?

I recently updated to tvOS 26 on my Apple TV 4K (1st generation) and was disappointed to find that apps I restrict no longer appear at all. In earlier versions, restricted apps would still be visible and simply prompt for a passcode — this was much more convenient for adults in the household. Now, if I restrict apps for my children, they disappear completely. To use them again, I have to go deep into settings, turn restrictions off, and even recreate the passcode each time, which is frustrating and impractical for daily use. I also tried adding a Kids user account, but most restrictions still apply system-wide. Only the Apple TV app behaves differently between users. This makes switching between parent and child accounts nearly pointless for managing access. Please consider one or both of the following: 1. Bring back the passcode-on-launch behavior for restricted apps (instead of hiding them). 2. Give each user their own isolated settings environment, like how profiles work on iOS/iPadOS or even a fresh Apple TV—this way, restrictions, home screen, and app access could be personalized. Families are a huge part of the Apple TV audience, and these recent changes have made it much harder to use the device in a shared household. Thank you!

The iPhone XS Max and Garmin watch pairing cannot use BLE to send Scan Response; it can only send BLE advertisements. May I ask if this is a limitation of the Apple system? So far, we have tested several iPhone models, and only the iPhone XS Max has this issue. We are not sure if other untested models have the same problem.

I am trying to develop a Watch and iOS app as companion. It is beyond stupid how I can not keep the watch connected to Xcode to develop. I have tried all the so-called tricks. Why is this so fragile? The phone is USB connected to my Mac I have tried turning off the wifi on my Mac and have the phone and watch on the same network. Nada I have tried just having everything on the same network. The watch is connected maybe 20% of the time. I have tried creating a hotspot network with my phone. The watch is connected maybe 50% of the time. This is truly an awful experience. Am I doing something wrong? Any advice would be grateful.

My client has provided me with admin access to the Apple Developer console. However, when I log in, I am prompted to enroll in the Apple Developer Program. Should I proceed with the enrollment myself, or does the client need to complete the enrollment from their own account?

iOS 18 System Bug Causes URL Scheme Failure A bug in iOS 18 causes URL Schemes to become invalid through the following steps, resulting in failure to open apps via URL Scheme. Reproduction Steps: Long-press the app icon Select "Require Face ID" Choose "Hide and Require Face ID" to hide the app Go to the App Library and locate the hidden app in the "Hidden" folder Uninstall the hidden app reinstalling the hidden app After reinstalling the app, all configured URL Schemes will become invalid, causing failure when attempting to open the app via URL Scheme. The issue appears to be that after uninstalling a hidden app and reinstalling it, the system fails to restore the app's URL Scheme functionality.

I applied to the Apple Developer Program on Jan 17 and my enrollment showed pending for several days. I eventually contacted support on the 27th and they told me they needed additional documentation and sent me a link to upload and asked me to email them once I've done so, so that they can get it reviewed quickly. On Jan 27, I uploaded the documents they requested and sent the email confirming they've been uploaded as was requested. After several days, it still says "pending". I spoke with support today and they said they have the documents and there's nothing for me to do other than wait for them to be reviewed and this "could take months". I'm in the process of purchasing a business and need this account so that they can transfer me the mobile app. My due diligence period is ending within a few days and need clarity on this approval asap. Has anyone else experienced these types of delays or know how to get the review completed? Enrollment ID: 7P992248Q5 Case ID: 102811401305

O v er the past few months, I’ve been experiencing persistent, abnormal behavior on my iPhone. Here's a short timeline: March 2025: Most apps log me out every time I close them. April 2025: Stored passwords suddenly begin failing across apps and websites. May–June 2025: Password recovery emails from Gmail accounts no longer arrive — suggesting that Gmail itself may be compromised or blocked/intercepted. Given the escalation, I ran several diagnostics and extracted system-level logs. Below is a structured summary of findings that point toward potential remote access, network traffic rerouting, and possibly hidden use of Bluetooth or debugging interfaces. ##1 Source: remotectl_dumpstate.txt More than 50 remote lockdown and diagnostic services are listed as active. Notable entries: com.apple.mobile.lockdown.remote.trusted and .untrusted com.apple.mobile.file_relay.shim.remote com.apple.webinspector.shim.remote com.apple.pcapd.shim.remote com.apple.bluetooth.BTPacketLogger.shim.remote com.apple.mobile.insecure_notification_proxy.remote This volume of .shim.remote and diagnostic services appears highly irregular for a non-debug, non-jailbroken device. 2. Skywalk Network Flows and Unusual Routing Source: skywalk.txt Dozens of flowswitch entries across interfaces like: ipsec0-7, pdp_ip0-2, en0-2, awdl0 Apps such as Gmail, ChatGPT, Preferences, and com.apple.WebKit are marked as defunct, yet persist in flow tables. Two specific daemons — replicatord and siriactionsd — appear on nearly every interface, in both QUIC and TCP6 traffic. skywalkctl flow-route shows multiple external IP paths, with flows routed through ipsec7, owned by kernel_task.0 — which could indicate system-level tunneling. 3. System Anomalies and Resource Behavior Inaccessible System Network Tools Source: get-network-info.txt All scutil calls fail (/usr/sbin/scutil does not exist). This blocks access to: DNS configuration (scutil --dns) Proxy and VPN status (scutil --proxy, --nc list) Reachability checks (scutil -r www.apple.com) Key Questions for the Developer Community Are >50 remote .shim.remote services typical on iOS 18.5 (release build)? Or does this suggest tampering, an MDM configuration, or debug provisioning? Could a misconfigured VPN or MDM profile enable persistent flow-switching across multiple interfaces (e.g., ipsec, pdp, awdl) and reroute app traffic such as Gmail? Is it possible for a test or developer certificate to silently side-load a background daemon, or trigger services like pcapd or file_relay, without showing in Profiles or Settings? Has anyone else seen the scutil binary missing or inaccessible on a stock iPhone? Could this be a sign of intentional lockdown or system modification? If anyone on iOS 18.5 / iPhone17,1 can share their remotectl_dumpstate output, I'd like to compare the service count and see if this behavior is reproducible. I’d appreciate any insight from those familiar with Apple’s system daemons, skywalk internals, or network service behavior. Happy to share sanitized logs or run additional diagnostics if needed. Thanks in advance. get-network-info.txt route-info.txt remotectl_dumpstate.txt [ assetsd.diskwrites_resource-2025-06-25-221428.json linkText

I am trying to create a new app using IOS-26.1, macOS Tahoe 26.1 and Xcode 26.1 with Swift6. Is this a bug that is going to be addressed. This is in the Debug Console...Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSAutoresizingMaskLayoutConstraint:0x10bb18870 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0.width == 0 (active)>", "<NSLayoutConstraint:0x115ac2ee0 _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0.leading == _UIButtonBarButton:0x115d40c80.leading (active)>", "<NSLayoutConstraint:0x115ac30c0 H:[_UIButtonBarButton:0x115d40c80]-(0)-| (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0 )>", "<NSLayoutConstraint:0x115ac2df0 'TB_Leading_Leading' H:|-(12)-[_UIModernBarButton:0x115d20a80] (active, names: '|':_UIButtonBarButton:0x115d40c80 )>", "<NSLayoutConstraint:0x115ac2fd0 'TB_Trailing_Trailing' H:[_UIModernBarButton:0x115d20a80]-(12)-| (active, names: '|':_UIButtonBarButton:0x115d40c80 )>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x115ac2fd0 'TB_Trailing_Trailing' H:[_UIModernBarButton:0x115d20a80]-(12)-| (active, names: '|':_UIButtonBarButton:0x115d40c80 )> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

Since the last Mac software upgrade, PDF's off my IMac are not being printed or aligned correctly. I have multiple printers and multiple apps and it all prints the same. This is not a "printer driver" issue or an app issue. I am suspecting that this may be an issue since upgrading to Sequonia 15.4.1. Looking to see if others have had this issue. Thanks.

iPhone 16 Pro Max on iOS 18.5 before installing iOS 26 beta had no issues connecting to wired (there’s no wireless) CarPlay in my 2022 Honda Civic Sport. Now with IOS 26, my car recognizes that my phone is connected and asks if I want to use CarPlay and I click yes but it does nothing. I reset my head unit, reset all iPhone settings, checked different iPhone settings, tried different cables, can’t seem to determine what part of iOS 26 is causing the problem. Anyone have any ideas before I roll back to 18.5?

I strongly dislike the new “Liquid Glass” design implementation, specifically the forced white border around app icons. I use custom app icons on my Home Screen, and the entire reason they work visually is because they do not have borders. The newly added white outline completely breaks the aesthetic, clashes with custom icon packs, and makes carefully curated Home Screens look messy and inconsistent. Beyond that, the “glass” effect itself is harder to appreciate in real-world use. Once you’re actually navigating your phone - opening apps, scrolling, switching screens- the effect becomes distracting rather than enhancing. The white border especially draws attention away from the icons themselves and makes the Home Screen feel visually noisy. What’s most frustrating is that this change is not optional. A major visual redesign like this should absolutely include: • A toggle to disable icon borders • Or a way to opt out of Liquid Glass entirely • Or at minimum, a “Classic / Flat Icons” option for users who value customization

Is anyone else experiencing issues with CarPlay with this beta update?

Since iOS 26.1 I'm running into the following iCloud issues. Contacts are not being synced to iOS and iPad OS at all, no matter how I re-enable contact syncing I can't get them to sync. Somehow, my Mac and iPad are able to send out iMessages, but not my iPhone. My iPhone can receive and sync what I've sent using my Mac and iPad Unable to save an airdropped contact

Some users of my app complain that it stops responding to touch after a while. The screen is still updating, and the app seems to be working normally otherwise. It just doesn't respond to any touches anymore. It is not a problem with the touchscreen itself, because the user is able to swipe up to get to the home screen, and then interact with other apps as normal. When re-opening my app, it is still unresponsive to touch. The only way to solve it, is to restart the app. Does anybody have a similar experience, and knows what could cause it? The app is based on UIKit, and still written in Objective-C, if it matters. The iOS version involved does not seem to matter, it happened with a couple of them.
