DiaryApp: Variable has incomplete type 'enum DiaryEntryMood' Compiler Error

I had the same issue like Jonathan Fernandez with incompatible type compiler error. I've deleted '*' from my enum code, but I'm still getting an error, expect this time it's "Variable has incomplete type 'enum DiaryEntryMood'". Maybe anyone know the answer? I spend one week on looking for the solution but nothing helps :/ I guess the solution is pretty simple but still it seems like I'm getting tired from this code because I can't figure out anything more. I put my code below:

Enum declaration:

#import "DiaryEntry.h"


enum {

    good = 0,
    average = 1,
    bad = 2

typedef int16_t DiaryEntryMood;

@interface DiaryEntry (CoreDataProperties)

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



Header file of entry view controller:

#import <UIKit/UIKit.h>

@class DiaryEntry;

@interface AddPostViewController : UIViewController

@property (weak, nonatomic) IBOutlet UITextField *textField;
@property (strong, nonatomic) DiaryEntry *entry;
@property (nonatomic, assign) enum DiaryEntryMood pickedMood;

@property (weak, nonatomic) IBOutlet UIButton *badButton;
@property (weak, nonatomic) IBOutlet UIButton *averageButton;
@property (weak, nonatomic) IBOutlet UIButton *goodButton;
@property (strong, nonatomic) IBOutlet UIView *accessoryView;


Implementation file of entry view controller:

#import "AddPostViewController.h"
#import "CoreDataStack.h"
#import "DiaryEntry+CoreDataProperties.h"

@interface AddPostViewController ()


@implementation AddPostViewController //Cannot synthesize property 'pickedMood' with incomplete type 'enum DiaryEntryMood'

- (void)viewDidLoad {
    [super viewDidLoad];

    if (self.entry != nil) {
        self.textField.text = self.entry.body;
        _pickedMood = self.entry.mood;
    } else{
        _pickedMood = good;

    self.textField.inputAccessoryView = self.accessoryView;

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.

- (void) insertDiaryEntry{

    CoreDataStack *coreDataStack = [CoreDataStack defaultStack];
    DiaryEntry *diaryEntry = [NSEntityDescription insertNewObjectForEntityForName:@"DiaryEntry" inManagedObjectContext:coreDataStack.managedObjectContext];
    diaryEntry.body = self.textField.text;
    diaryEntry.mood = _pickedMood;
    diaryEntry.date = [[NSDate date] timeIntervalSince1970];

    [coreDataStack saveContext];

- (void) updateDiary{

    self.entry.body = self.textField.text;

    self.entry.mood = _pickedMood;
    CoreDataStack *coreDataStack = [CoreDataStack defaultStack];
    [coreDataStack saveContext];

-(void)setPickedMood:(enum DiaryEntryMood)pickedMood { //Variable has incomplete type 'enum DiaryEntryMood'

    _pickedMood = pickedMood;

    self.badButton.alpha = 0.5;
    self.averageButton.alpha = 0.5;
    self.goodButton.alpha = 0.5;

    switch (pickedMood) {
        case bad:
            self.badButton.alpha = 1.0;

        case average:
            self.averageButton.alpha = 1.0;

        case good:
            self.goodButton.alpha = 1.0;


- (void) dismissSelf{
    [self.presentingViewController dismissViewControllerAnimated:true completion:nil];

- (IBAction)doneButtonPressed:(id)sender {

    if (self.entry != nil) {
        [self updateDiary];
    } else{
        [self insertDiaryEntry];
    [self dismissSelf];

- (IBAction)cancelButtonPressed:(id)sender {

    [self dismissSelf];

- (IBAction)badWasPressed:(id)sender {
    _pickedMood = bad;

- (IBAction)averageWasPressed:(id)sender {
    _pickedMood = average;

- (IBAction)goodWasPressed:(id)sender {
    _pickedMood = good;


Pleeeeeeeeease does anybody know the solution? Thanks for answers! :D
