Warning: makes integer from pointer without a cast

I am quite puzzled why this warning pops up. I use the same procedure on other controllers where it works perfectly.

ConditionTableViewController.m:57: warning: passing argument 1 of 'initWithCondition:' makes integer from pointer without a cast

With the following code

- (void)managedObjectSelected:(NSManagedObject *)managedObject
{
// Load View
Condition *con = (Condition *)managedObject;
ConditionDetailViewController *detail = [[ConditionDetailViewController alloc] initWithCondition:con];

detail.title = [[managedObject valueForKey:@"cave"] valueForKey:@"title"];

self.navigationItem.backBarButtonItem =
[[[UIBarButtonItem alloc] initWithTitle:@"Back"
                                  style: UIBarButtonItemStyleBordered
                                 target:nil
                                 action:nil] autorelease];

[self.navigationController pushViewController:detail animated:YES];
[detail release];
}

In ConditionDetailViewController.h

- (id)initWithCondition:(Condition *)aCondition开发者_Python百科;

Here the console output of "con"

initWithCondition: is a method of the NSConditionLock class in the Foundation framework that takes an integer. I think Xcode has somehow confused the symbol names initWithCondition: from two classes, and is using the wrong version. If your code is correct, including importing the correct headers in every file, it's probably a faulty index or precompiled header. Try deleting the derived data for the project from the "Projects" section of the "Organizer" window, and rebuilding the project.
