Parse SDK and Swift: Incorrect argument label in call PFObject 'withoutDataWithObjectId'

Question

I subclass PFObject exactly as described here.

Then I create a new instance of the subclassed object without data, but since Swift 1.2 I get an error (It did work perfectly before):

var test = Armor(withoutDataWithObjectId: "1234567890")

-> Xcode complains:

"Incorrect argument label in call (have 'withoutDataWithObjectId:', expected: 'className:')"

Why className? It should get the class name from the class function parseClassName

And I can under no circumstances create a new object with objectId but no data (which I MUST have to fetch it from the local datastore)

This is super annoying as my app doesn't compile any longer.

Answer 1

It may be a little late to answer this question.

I use swift 1.2, and v 1.7.5 Parse SDK, and it works totally fine.

however, make sure you have define objective-c bridging header in "build setting".

and try to run it, even though there may reports some error

Answer 2

Update to the newest Parse SDK, available here.

The issue is caused due to necessary adaptions in the Parse SDK after the Swift language update. This issue also occurs with the most recent update to Swift 2.2. The newest (as of today) Parse SDK release 1.13.0 already fixes this.

UPDATE

Parse iOS SDK 1.13.0 has a typo and the function PFUser(withoutDataWithObjectId:) is called PFUser(outDataWithObjectId:). So upgrading the Parse SDK alone does solve this. Until this is fixed a temporary workaround would be to extend PFObject with a convenience initializer. To do this add a new Swift file to your project and insert this:

import Parse

extension PFObject {
    convenience init(withoutDataWithObjectId objectId: String?) {
        self.init(outDataWithObjectId: objectId)
    }
}
