FBSDK Login Error Code: 308 in Objective-C
The solution below works for iOS9 + running on Xcode 8, for Swift3.0
The steps are
- Setup Facebook Launch
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
Setup Open Url
guard let source = options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String else { return false } let annotation = options[UIApplicationOpenURLOptionsAnnotationKey] as? String return FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: source, annotation: annotation)- Fix Keychain permission issue as shown in the image below
One solution, at least for me, is to not run on device via the Xcode debugger. If I run the app on device outside the debugger the Facebook login works fine. If I run the app in the sim via the debugger the Facebook login works fine.
Only if I run the app on device via the Xcode debugger do I get the com.facebook.sdk.login error 308 every time.
You should enable Keychain Sharing on the Capabilities tab.
