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:// )
