Facebook SDK in Swift - ios

Question

I am trying to integrate Facebook login and more into my app but am having a lot of difficulty because there is not much documentation in Swift. I am trying to use this code:
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"/me"
parameters:#{ #"fields": #"id,name,friends,birthday,gender,first_name,last_name,friendlists,picture",}
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
// Insert your code here
}];
Any idea what this would be in Swift?

Answer 1

FBSDKGraphRequest(graphPath: "me",
parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email, gender"])
.startWithCompletionHandler({ (connection, result, error) -> Void in
})

//MARK: - Functions Fb Logic
func signInWithFacebook()
{
if (FBSDKAccessToken.currentAccessToken() != nil) {
// User is already logged in, do work such as go to next view controller.
print("already logged in ")
returnUserData()
return
}
let faceBookLoginManger = FBSDKLoginManager()
faceBookLoginManger.logInWithReadPermissions(["public_profile", "email"], fromViewController:nil, handler: { (result, error)-> Void in
//result is FBSDKLoginManagerLoginResult
if (error != nil) {
print("error is \(error)")
} else if (result.isCancelled) {
//handle cancelations
} else if result.grantedPermissions.contains("email") {
self.returnUserData()
}
})
}
func returnUserData() {
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil) {
// Process error
print("Error: \(error)")
} else {
let accessToken = FBSDKAccessToken.currentAccessToken().tokenString
print("the access token is \(accessToken)")
let userID = result.valueForKey("id") as! NSString
let facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"
print("facebookProfileUrl: \(facebookProfileUrl)")
print("fetched user: \(result)")
}
})
}
}
