Facebook SDK login throws error in swift 2 iOS 9

Question

I tried to make a simple Facebook login with the Facebook SDK in iOS 9 and Swift 2 but it always throws me an error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSTaggedPointerString containsObject:]: unrecognized selector sent to instance 0xa326874756162667'

It occurs in the usr/include/dispatch/once.h and I can't solve it alone. Does somebody have any idea?

The code is here:

import FBSDKCoreKit
import FBSDKLoginKit


let loginManager = FBSDKLoginManager()
loginManager.logInWithReadPermissions(["basic_info", "email", "user_likes"], fromViewController: self.parentViewController, handler: { (result, error) -> Void in
    if error != nil {
        print(FBSDKAccessToken.currentAccessToken())
    } else if result.isCancelled {
        print("Cancelled")
    } else {
        print("LoggedIn")
    }
})

libc++abi.dylib: terminating with uncaught exception of type NSException

Thanks in advance.

Answer 1

I have solved the problem. As there is no anything about LSApplicationQueriesSchemes in the documentation but I got an error message about the lack of it I wrote the key and the "fbauth2" value into the info.plist as a String but it is an array and the SDK try to get the element of the String Array without any check if it is an array.

However, thank you for the helping answers.

Answer 2

Check the link to know more about adding 'fbauth2' to .plist while integrating FacebookSDK in iOS9.

FYI,
I was facing a crash with the following message:

*** Terminating app due to uncaught exception 'InvalidOperationException', reason: 'fbauth2 is missing from your Info.plist under LSApplicationQueriesSchemes and is required for iOS 9.0'
*** First throw call stack:

And solved it by adding the following in .plist

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>
