PFFacebookUtils initializeFacebookWithApplicationLaunchOptions freezes app (semaphore wait trap)

Question

On the next launch after logging using FB, app freezes on initializeFacebookWithApplicationLaunchOptions . Heard it was a problem before Parse v1.7.2, but I'm using latest SDKs:

Installing Bolts (1.2.2)
Installing FBSDKCoreKit (4.6.0)
Installing FBSDKLoginKit (4.6.0)
Installing FBSDKShareKit (4.6.0)
Installing Parse (1.8.5)
Installing ParseFacebookUtilsV4 (1.8.5)

(xcode 7.0, ios 9.0)

Anyone knows what's the problem?

Answer 1

It was a bug due to FBSDK was trying to post a notification on the main thread and was blocking it. Should be fixed in parse ios sdk 1.8.6.
