You need to initialize the variable before use it inside a closure:
As per apple documentation
If you use a closure to initialize a property, remember that the rest
of the instance has not yet been initialized at the point that the
closure is executed. This means that you cannot access any other
property values from within your closure, even if those properties
have default values. You also cannot use the implicit self property,
or call any of the instance’s methods.
The command var numberOfGames: Int just declare it to initialize you can use var numberOfGames = Int() or var numberOfGames:Int = 0
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
var user: PFUser!
var numberOfGames:Int = 0
var query = PFQuery.orQueryWithSubqueries([userQuery, userQuery2, currentUserQuery, currentUserQuery2])
query.findObjectsInBackgroundWithBlock{
(results: [AnyObject]?, error: NSError?) -> Void in
if error != nil {
println(error)
}
if error == nil{
if results != nil{
println(results)
numberOfGames = results!.count as Int
}
}
}
return numberOfGames
}
