I'm creating two custom PFObject subclass: Match and Set A match has a property called setTest which point to a Set. Both class are registered with Parse in the app delegate. When I initialize a match object (which creates a set object too), i get an exception.
What am I doing wrong?
Thanks!
Match class:
class Match: PFObject, PFSubclassing
{
@NSManaged var setTest:Set?
convenience init (defaults:String?)
{
self.init()
self.setTest = Set(withPlayer1Score: 0, player2Score: 0)
}
}
static func parseClassName() -> String
{
return "Match"
}
Set class:
class Set: PFObject, PFSubclassing {
@NSManaged var player1Score:NSNumber?
@NSManaged var player2Score:NSNumber?
convenience init(withPlayer1Score player1Score:Int, player2Score:Int) {
self.init()
self.player1Score = player1Score
self.player2Score = player2Score
}
//MARK: PFSubclassing
static func parseClassName() -> String
{
return "Set"
}
}
Then somewhere in code i call
let match = Match(defaults: nil)
match.startDate = NSDate()
match.saveInBackgroundWithBlock({ (completed:Bool, error:NSError?) -> Void in
assert(completed)
})
When saveInBackground() runs, I get the following exception:
2015-12-31 14:41:18.337 TenStats Debug[4055:2031064] [Error]: Caught "NSInternalInconsistencyException" with reason "Found a circular dependency when saving.":

You can't set an object as the destination of a pointer or add it to a relationship until it has been saved. The exception you see isn't a very good explanation of that but you will need to save the Set before you connect it to the Match.
