FacebookLoginSDK 4 Apple Mach-O Linker Error

Question

I am trying to integrate FacebookLogin SDK 4 into my IOS app using Swift 3. I added the following 3 frameworks: Bolts, FBSDKCoreKit and FBSDKLoginKit. I changed my Info.plist according to Facebook documentation, created the Bridging header file, and added its path to my Build Settings.

Once I add the following line in my AppDelegate.swift file, I am getting:

Apple Mach-O Linker Error:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
        return true
    }

I tried the options provided here: Apple Mach-O Linker Error when compiling for device None of them helped (unless I am missing something). Has anyone else had a similar problem? Please help.

Have u added this method in app delegate

   func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
        -> Bool {
            return FBSDKApplicationDelegate.sharedInstance().application(application, open: url as URL!, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: [:])
}

also this one in willResignActive method

func applicationWillResignActive(_ application: UIApplication)
{
     FBSDKAppEvents.activateApp()
}

@codedev . Once remove fb integration run build the project , install fb integration again . – Uma Madhavi Dec 18 '17 at 05:59
I just tried it, deleted all the frameworks and added them back. Still same error. When I comment out the lines related with FBSDK it works fine. – codedev Dec 18 '17 at 06:09
@codedev Create one new project add fb integration in that & check whether its working fine or not – Uma Madhavi Dec 18 '17 at 06:57
