NEVPNManager停止使用iOS 14测试版

Question

我已经尝试在iOS 14测试版上运行我的应用程序。它在iOS 13上运行良好，但在iOS 14测试版上无法连接到任何服务器。NEVPNManager.shared().connection.startVPNTunnel()没有抛出任何错误，并且我连接的任何服务器上的NEVPNStatus都变成了.disconnected。我找不到iOS 14上的NEVPNManager有什么变化。

这是我的经理的配置：

let p = NEVPNProtocolIKEv2()
p.authenticationMethod = NEVPNIKEAuthenticationMethod.none
p.serverAddress = account.server
p.disconnectOnSleep = false
p.deadPeerDetectionRate = NEVPNIKEv2DeadPeerDetectionRate.medium
p.username = account.account
p.passwordReference = KeychainWrapper.passwordRefForVPNID()
p.disableMOBIKE = false
p.disableRedirect = false
p.enableRevocationCheck = false
p.enablePFS = false
p.useExtendedAuthentication = true
p.useConfigurationAttributeInternalIPSubnet = false
p.remoteIdentifier = account.server
p.localIdentifier = account.account
            
let manager = NEVPNManager.shared()
manager.protocolConfiguration = p
manager.isEnabled = true
let ruleConnect = NEOnDemandRuleConnect()
ruleConnect.probeURL = account.probeUrl
manager.onDemandRules = [ruleConnect]
manager.isOnDemandEnabled = true

苹果似乎更改了iOS 14上的密码(有文档)，你可以在这里看到一些线程：

如果你像我一样使用StrongSwan，你可以通过从你的虚拟专用网络服务器更新配置来修复它，只需设置ike=aes256-sha2_256-modp2048和esp=aes256-sha2_256，然后重启StrongSwan，然后它就可以在iOS 14上工作了。参考：https://wiki.strongswan.org/projects/strongswan/wiki/AppleClients
