Simplified, the code is this:
func login() {
NSLog("Will login with read permissions")
FBSDKLoginManager().logInWithReadPermissions(
["public_profile"],
handler: {
(result: FBSDKLoginManagerLoginResult!, error: NSError!) -> Void in
NSLog("Handler is called")
})
NSLog("Returning from login")
}
When this is called, it produces the following log statements:
2015-05-25 11:35:07.886 MyApp[1213:646722] Will login with read permissions
2015-05-25 11:44:22.048 MyApp[1213:646722] Returning from login
(The large time difference between the statements above is due to me using the debugger to step through the internals of logInWithReadPermissions. Running without the debugger does not change the behavior.)
I have tried this on a device with the Facebook native app installed and me logged in, and I have tried this on a device without the native app where I had never accessed Facebook at all. I have also tried this on simulators. I get the same result.
I am assuming that this is a synchronous call, but just in case, I tried waiting indefinitely in the calling thread -- the handler is still never called, and nothing visible is happening on the device.
I turned on all the logging that I could find:
FBSDKSettings.setLoggingBehavior(
[FBSDKLoggingBehaviorAppEvents,
FBSDKLoggingBehaviorInformational,
FBSDKLoggingBehaviorAccessTokens,
FBSDKLoggingBehaviorUIControlErrors,
FBSDKLoggingBehaviorGraphAPIDebugWarning,
FBSDKLoggingBehaviorGraphAPIDebugInfo,
FBSDKLoggingBehaviorNetworkRequests,
FBSDKLoggingBehaviorCacheErrors,
FBSDKLoggingBehaviorDeveloperErrors])
Then, on startup, I am getting either this:

Either way, my handler is never called, yet the logInWithReadPermissions function returns alright.
I have implemented all of the following in my AppDelegate:
func application(application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(
application,
didFinishLaunchingWithOptions: launchOptions)
}
func applicationDidBecomeActive(application: UIApplication) {
FBSDKAppEvents.activateApp()
}
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(
application,
openURL: url,
sourceApplication: sourceApplication,
annotation: annotation)
}
I have these lines in my Info.plist:
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb140xxxxxxxxxxxxx</string>
</array>
</dict>
</array>
<key>FacebookAppID</key>
<string>140xxxxxxxxxxxxx</string>
<key>FacebookDisplayName</key>
<string>MyApp</string>
Anything I am missing in the above? If not, how do I go about debugging this further? Any logging that I can turn on or off? Anything in my app settings on either XCode or Facebook side anyone can think of that I could look at?

You said:
"I tried waiting indefinitely in the calling thread -- the handler is still never called, and nothing visible is happening on the device."
The call is definitely not synchronous, and if you keep the main thread busy in a tight wait loop, then it won't be able to "call you back".
Another thing to check is to make sure that your app delegate does not also implement
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
If you implement this method in your app delegate, then the other implementation will be ignored:
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool
