error: property 'airportIATA' not found on object of type 'Flight *' [3]
...
@interface Flight : NSManagedObject
@property (nonatomic, retain) NSString * airportIATA;
...
But this property exists. Is it any way to reset Xcode4?
Upd. It seems that Xcode began to use old .xcdatamodel, it shows also warnings like
Incompatible pointer types passing 'NSString *' to parameter of type 'Airport *'
But I changed property from Airport class to NSString two days ago.
