I have tried to insert 1L key-values into the user defaults. It is working fine until 50k key-values. After some time, am getting Not updating lastKnownShmemState in CFPrefsPlistSource<0x2825b0c60> (Domain: peformance_validator, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No) also, key-values are not updating in the plist as well. peformance_validator is my user defaults group name. How can I solve this ?

Hi , I have a problem with observing call status in iPadOS 14. callObserver:callChanged: method not invoked when I initiate a cellular call from iPad ( using url as tel://). But same code working fine in iPhone - iOS 14. My Code , import UIKit import CallKit class ViewController: UIViewController, CXCallObserverDelegate {         private lazy var callObserver = CXCallObserver()     override func viewDidLoad() {         super.viewDidLoad()         configureCallButton()         view.backgroundColor = .gray         self.callObserver.setDelegate(self, queue: nil)         // Do any additional setup after loading the view.     }     func configureCallButton() {         let button = UIButton(type: .system)         button.setTitle("Call", for: .normal)         let attStr = NSMutableAttributedString(string: "Call", attributes: [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 25), NSAttributedString.Key.foregroundColor: UIColor.blue]);         button.setAttributedTitle(attStr, for: .normal)         button.translatesAutoresizingMaskIntoConstraints = false         view.addSubview(button)         button.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true         button.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true         button.addTarget(self, action: #selector(initiateCall), for: .touchUpInside)     }     @objc func initiateCall() {         if let url = URL(string: "tel://*********") {              UIApplication.shared.openURL(url)          }     }     func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {         if call.isOutgoing {             print("Call outgoing")         }         else if call.hasConnected {             print("Call has connected")         }         else if call.hasEnded {             print("Call has ended")         }     } } Note: Observer method invoked for FaceTime calls in iPadOS 14.( using url as facetime:// )

We check [UIApplication sharedApplication].keyWindow.traitCollection.forceTouchCapability = UIForceTouchCapabilityAvailable to find the 3D touch support. If supported we added shortcut items to the application.But in iPhone XR above check always return false. How to validate whether the device has supported Haptic Touch or not ?

how to check the content present in the assets.car and unix executable file .ipa.
