Question

I’m having a ton of errors for my generated model objects:

ExerciseSet.h

1  @class Exercise;
2 
3  @interface ExerciseSet : NSManagedObject
4 
5  @property (nonatomic, retain) NSNumber * order;
6  @property (nonatomic, retain) NSNumber * reps;
7  @property (nonatomic, retain) NSNumber * weight;
8  @property (nonatomic, retain) Exercise *belongsTo;
9
10 @end

• Illegal interface qualifier on line 1.
• Expected identifier or '(' on line 3.
• Unknown type name 'Exercise' on line 8
• Property with 'retain (or strong)' attribute must be of object type on line 8.
• Warning for all properties for not calling @synthesize, or @dynamic(which of course are called)

Exercise.h

1  @class ExerciseName, ExerciseSet, Workout, WorkoutMethod;
2
3  @interface Exercise : NSManagedObject
4
5  @property (nonatomic, retain) NSString * notes;
6  @property (nonatomic, retain) NSDecimalNumber * restBetweenSets;
7  @property (nonatomic, retain) NSNumber * rmMethod;
8  @property (nonatomic, retain) NSDecimalNumber * rmResult;
9  @property (nonatomic, retain) Workout *belongsTo;
10 @property (nonatomic, retain) NSSet *hasSet;
11 @property (nonatomic, retain) WorkoutMethod *isDoneWith;
12 @property (nonatomic, retain) ExerciseName *takesNameFrom;
13 @end
14 
15 @interface Exercise (CoreDataGeneratedAccessors)
16 
17 - (void)addHasSetObject:(ExerciseSet *)value;
18 - (void)removeHasSetObject:(ExerciseSet *)value;
19 - (void)addHasSet:(NSSet *)values;
20 - (void)removeHasSet:(NSSet *)values;
21 @end

• Illegal interface qualifier on line 1.
• Missing @end on line 3.
• Unknown type name 'Workout' on line 9.
• etc.

The other forward declared interfaces are ok, with no problems or errors.

What could cause this behavior?

Answer 1

I upgraded to Xcode 4.3, regenerated the NSManagedObject subclasses and the errors disappeared. It must’ve been a bug in Xcode.

Thanks for your help anyways!
