Objective C to Swift Methods call?

Question

Here is my objective c method call that I need to convert to a swift call.

It's complaining that "Could not find an overload for logInWithUsernameInBackground that accepts the supplied arguments.

What am I doing wrong?

Objective C Method Decleration

typedef void (^PFUserResultBlock)(PFUser *user, NSError *error); + (void)logInWithUsernameInBackground:(NSString *)username password:(NSString *)password block:(PFUserResultBlock)block;

Objective C Call

[User logInWithUsernameInBackground:@"" password:@"" block:^(PFUser *user, NSError *error) { NSLog(@"test"); }];

Swift

User.logInWithUsernameInBackground("", password: "", block: { (user: PFUser?, error: NSError) -> Void in NSLog("test") } )

Please show the declaration of this method in Objective-C. That, not how you were calling it, is what's important. — matt

let compiler figure out the correct type for you with type inference

User.logInWithUsernameInBackground("", password: "", block: { (user, error) in NSLog("test") } )

Objective c used to autocomplete the block definition for you. Doesn't seem like this is happening for closures in swift
