Xcode5 'Attempt to implement instance selector with incompatible block (selector: -popoverControllerDidDismissPopover:)'

[nilskasseckert]

Hi,
I have following Code:
"__weak KDChildEditViewController * weakSelf = self;
[self.popover setDidDismissBlock:^(UIPopoverController * controller) {
weakSelf.child.dateOfBirth = picker.date;
weakSelf.dateView.text = weakSelf.child.dateOfBirth.prettyDate;
}];"
Under Xcode 4.4 that work's without Problems. In Xcode 5 I become following Error: "Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Attempt to implement instance selector with incompatible block (selector: -popoverControllerDidDismissPopover:)'" Why? What can I do?

Best regards
Nils
