I'm trying to integrate facebook login in my parse application. I followed every step mentioned in parse tutorial. In the below code, I'm getting compilation error.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
line1: Parse.setApplicationId("xxx", clientKey: "yyy")
line2: PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
line3: PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
line4: return true
}
In line 3 , I'm getting error:
Value of optional type '
[NSObject:AnyObject]
' not unwrapped; did you mean to use '!
' or '?
'?
If I manually unwrap it using ' !
', because launchOptions can be nil, I get:
Fatal error: unexpectedly found nil while unwrapping an Optional value
If I check for nil, I get:
NSInternalInconsistencyException
', reason: 'You must initialize PFFacebookUtils with a call to+initializeFacebookWithApplicationLaunchOptions
Any idea how to fix it?
It is a bug in ParseSDK. Until Parse fix this you can change the initialize function declaration at PFFacebookUtils.h header file
1) Go to PFFacebookUtils.h
2) change:

The problem was a bug of ParseSDK, it does not accept nil launchOptions
According to the the answer provided by Roger Ingouacka at https://developers.facebook.com/bugs/1462780714012820/
if let launchOptions = launchOptions {
PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
} else {
PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions([NSObject:AnyObject]())
}
Notice the use of
[NSObject:AnyObject]()
This problem persisted untill I updated to Parse library 1.8.1 .
I tried adjusting PFFacebookUtils.h, and a lot of other things, but that did not solve it. It was driving me insane.
