Placed the Enum inside ____+CoreDataProperties.m below the #import statement and it compiled fine.

Can you post the full code for the .m and the .h files?

Also, two other things to check:

If you search your project, are there other places you declare: THDiaryEntryMood and/or THDiaryEntry

and

If you look in your project navigator, are there two copies of either of the files containing THDiaryEntry

// // THDiaryEntry.h // diary // // Created by Tim Polehn on 8/13/15. // Copyright (c) 2015 TimothyPolehn. All rights reserved. //

import <Foundation/Foundation.h>

import <CoreData/CoreData.h>

NS_ENUM(int16_t, THDiaryEntryMood){ THDiaryEntryMoodGood = 0, THDiaryEntryMoodAverage = 1, THDiaryEntryMoodBad = 2 };

@interface THDiaryEntry : NSManagedObject

@property (nonatomic, retain) NSString * body; @property (nonatomic) NSTimeInterval date; @property (nonatomic, retain) NSData * imageData; @property (nonatomic, retain) NSString * location; @property (nonatomic) int16_t mood;

@end

// // THDiaryEntry.m // diary // // Created by Tim Polehn on 8/13/15. // Copyright (c) 2015 TimothyPolehn. All rights reserved. //

import "THDiaryEntry.h"

@implementation THDiaryEntry

@dynamic body; @dynamic date; @dynamic imageData; @dynamic location; @dynamic mood;

@end

Try declaring your enum like this:

enum THDiaryEntryMood{THDiaryEntryMoodGood = 0, THDiaryEntryMoodAverage = 1, THDiaryEntryMoodBad = 2};

Also, where else in your PROJECT do any of the "THDiaryEntryMood" values above get used? Do a search of your project and please post that code too.
