Hi there, I’m having issue using Apple’s API. I can’t initialize SFAuthorizationPluginView using Swift. I’ve done numerous google searches, but haven’t found any examples/tutorials of anyone using Swift for SFAuthorizationPluginView / AuthorizationPluginCreate. I managed to get the AuthorizationPlugin and AuthorizationMechanism up, but simply creating the SFAuthorizationPluginView fails the failable initiator. https://developer.apple.com/documentation/securityinterface/sfauthorizationpluginview Here are some log messages I wrote: error 16:08:33.689244-0800 kernel Library Validation failed: Rejecting '/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent' (Team ID: 7X6364JT77, platform: no) for process 'SecurityAgentHel(2689)' (Team ID: N/A, platform: yes), reason: mapping process is a platform binary, but mapped file is not error 16:08:33.689501-0800 SecurityAgentHelper-arm64 Error loading /Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent (78): dlopen(/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent, 0x0106): tried: '/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent' (code signature in <BFF0D7BA-5CF8-3F2F-A604-DCC235499234> '/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent' not valid for use in process: mapping process is a platform binary, but mapped file is not), '/System/Volumes/Preboot/Cryptexes/OS/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent' (no such file), '/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent' (code signature in <BFF0D7BA-5CF8-3F2F-A604-DCC235499234> '/Library/Security/SecurityAgentPlugins/XXXAgent.bundle/Contents/MacOS/XXXAgent' not valid for use in process: mapping process is a platform binary, but mapped file is not) default 16:08:33.760679-0800 SecurityAgentHelper-arm64 callbacks: Optional(0x00000001001b1f88) default 16:08:33.760710-0800 SecurityAgentHelper-arm64 andEngineRef: Optional(0x0000000156f384d0) error 16:08:33.762404-0800 SecurityAgentHelper-arm64 Test API call result: OSStatus 0 i.e. No error. error 16:08:33.763298-0800 SecurityAgentHelper-arm64 Failed to create Authorization Plugin Adapter default 16:08:33.763524-0800 authd engine 66: running mechanism XXXAgent:XXXAgentMechanism (1 of 1) Here is the calling code with the error message: class AuthorizationMechanismXXX : AuthorizationMechanism { let mLogger = … let mAuthorizationPluginView : AuthorizationPluginViewAdapter? override init(inPlugin: UnsafeMutablePointer<AuthorizationPlugin>, inEngine: AuthorizationEngineRef, inMechanismId: AuthorizationMechanismId) { … let pCallbacks : UnsafePointer<AuthorizationCallbacks> = inPlugin.pointee.EngineCallback() self.mAuthorizationPluginView = AuthorizationPluginViewAdapter(callbacks: pCallbacks, andEngineRef: inEngine) if (self.mAuthorizationPluginView == nil) { mLogger.error("Failed to create Authorization Plugin Adapter") } super.init(inPlugin: inPlugin, inEngine: inEngine, inMechanismId: inMechanismId) } Here is the class: class AuthorizationPluginViewAdapter : SFAuthorizationPluginView { let mLogger = … let mLoginView = NSHostingView(rootView: LoginView()) override init!(callbacks: UnsafePointer<AuthorizationCallbacks>!, andEngineRef engineRef: AuthorizationEngineRef!) { mLogger.notice("callbacks: \(callbacks.debugDescription, privacy: .public)") mLogger.notice("andEngineRef: \(engineRef.debugDescription, privacy: .public)") var sessionId: UnsafeMutablePointer<AuthorizationSessionId?>? let result = callbacks.pointee.GetSessionId(engineRef, sessionId) LogSecurityOSStatus(logger: mLogger, osStatus: result, message: "Test API call result") super.init(callbacks: callbacks, andEngineRef: engineRef) mLogger.notice("Never gets here") } override func buttonPressed(_ inButtonType: SFButtonType) { if (inButtonType == SFButtonTypeOK) { let osStatus = callbacks().pointee.SetResult(engineRef(), AuthorizationResult.allow) if (osStatus != errSecSuccess) { LogSecurityOSStatus(logger: mLogger, osStatus: osStatus, message: "Error setting authorization result") } } else if (inButtonType == SFButtonTypeCancel) { let osStatus = callbacks().pointee.SetResult(engineRef(), AuthorizationResult.deny) if osStatus != errSecSuccess { LogSecurityOSStatus(logger: mLogger, osStatus: osStatus, message: "Error setting authorization result") } } else { mLogger.error("Invalid buttonType.") } } override func view(for inType: SFViewType) -> NSView! { if (inType == SFViewTypeIdentityAndCredentials) { mLogger.debug("Identity and credentials") } else if (inType == SFViewTypeCredentials) { mLogger.debug("Credentials only") } else { mLogger.error("Invalid buttonType.") } return mLoginView } } Here is the view: import SwiftUI struct LoginView: View { var body: some View { Text(/*@START_MENU_TOKEN@*/"Hello, World!"/*@END_MENU_TOKEN@*/) } } #Preview { LoginView() }
