I have the following code that is attempting to set up Hotspot 2.0 using an EAP-TLS configuration. I am importing a pk12 file and using those certificates. I have tried all manner of permutations for the configuration, and have narrowed down all the errors I was getting and now I am just getting a generic: Error: invalid EAP settings. I have tried adding the identity separately and either get an entitlements issue which I can't figure out why since I have added the required network extension sharing groups, or a duplicate item error, meaning it was already correctly added. The certificate and configuration are correctly working through an Android app already. static let accessGroup: String? = { guard let prefix = Bundle.main.object(forInfoDictionaryKey: "AppIdentifierPrefix") as? String else { print("Could not load group") return nil } return "\(prefix)com.apple.networkextensionsharing" }() static func setupHotspot(data: CertificateData) { let h20 = NEHotspotHS20Settings(domainName: data.realm, roamingEnabled: false) h20.naiRealmNames = [data.realm] var result: CFArray? let options: [CFString: Any] = [ kSecImportExportPassphrase: "**********", kSecAttrLabel: "ident:\(data.user)", kSecAttrAccessGroup: accessGroup!, kSecReturnPersistentRef: true ] let status = SecPKCS12Import(data.p12 as CFData, options as CFDictionary, &result) guard status == errSecSuccess, let importResult = result as? [[String: Any]], let resultDict = importResult.first else { print("P12 Import failed: \(status)") return } let identity = resultDict[kSecImportItemIdentity as String] as! SecIdentity let eap = NEHotspotEAPSettings() eap.supportedEAPTypes = [NEHotspotEAPSettings.EAPType.EAPTLS.rawValue as NSNumber] eap.isTLSClientCertificateRequired = true eap.trustedServerNames = [ data.realm ] eap.outerIdentity = "anonymous" guard eap.setIdentity( identity ) else { print("setIdentity failed") return } let configuration = NEHotspotConfiguration(hs20Settings: h20, eapSettings: eap) NEHotspotConfigurationManager.shared.apply(configuration) { error in if let error = error { print("Error: \(error.localizedDescription)") } else { print("Success") } } }
