VPN 未在 Mac Catalyst 上连接，出现错误，即返回 SecKeychainItemCopyContent 无法检索此项目的内容

问题描述

VPN 已成功连接到 iOS 和 macOS 本机应用程序，但无法在 mac Catalyst 上运行。在控制台中出现错误，即返回 SecKeychainItemcopyContent 无法检索此项目的内容。

VPN 钥匙串参考： https://developer.apple.com/forums/thread/84194

注意：我已经在“功能”选项卡中启用了个人 VPN 和钥匙串共享。

下面是我的代码-

VPN.shared.loadPreferences(userName: "someuser",password: "cankcajca",serverIP: "someIP",secret: "kjnkjcakjncka") { (success,errorMessage) in
            print("VPN callback")
            VPN.shared.connectVPN { (success) in
                print("connected")
            }
        }



    public func loadPreferences(userName: String,password: String,serverIP: String,secret: String,completionHandler: ((Bool,String?) -> Void)?) {
        self.userName = userName
        self.password = password
        self.serverIP = serverIP
        self.secret = secret
        
        self.vpnManager.loadFromPreferences {[weak self] (error) in
            guard let `self` = self else {
                completionHandler?(false,nil)
                return
            }
            
            if let tempError = error{
                completionHandler?(false,tempError.localizedDescription)
            }else{
                let vpnProtocol = NEVPNProtocolIPSec()
                vpnProtocol.username = self.userName
                vpnProtocol.serverAddress = self.serverIP
                vpnProtocol.authenticationMethod = NEVPNIKEAuthenticationMethod.sharedSecret
                if let secretRef = try? VPNKeychain.persistentReferenceFor(service: "VPN_Service2",account: "VPN_SECRET2",password: self.secret.data(using: .utf8)!){
                    vpnProtocol.sharedSecretReference = secretRef
                }
                
                if let passRef = try? VPNKeychain.persistentReferenceFor(service: "VPN_Service2",account: "VPN_PASSWORD2",password: self.password.data(using: .utf8)!){
                    vpnProtocol.passwordReference = passRef
                }
                
                vpnProtocol.useExtendedAuthentication = true
                vpnProtocol.disconnectOnSleep = false
                self.vpnManager.protocolConfiguration = vpnProtocol
                self.vpnManager.localizedDescription = "WH_VPN"
                self.vpnManager.isEnabled = true
                self.vpnManager.savetoPreferences {(error) in
                    if let tempError = error{
                        completionHandler?(false,tempError.localizedDescription)
                    }else{
                        completionHandler?(true,nil)
                    }
                }
            }
        }
    }
    
    public func connectVPN(completionHandler: ((Bool) -> Void)?) {
        if vpnManager.connection.status == .connecting || vpnManager.connection.status == .connected  { return }
        
        self.connectHandler = completionHandler
        do {
            try self.vpnManager.connection.startVPNTunnel()
        } catch {
            print("connectVPN Failed: \(error.localizedDescription)")
        }
    }
