Please remove the line:

#import <UIKit/UIKit.h>

from User.h and it should pass

Bharath,

My apologies for the inconvenience with this issue. Yes, I have tested it through all 3 tasks and it works if you remove the #import UIKit/UIKit.h line from User.h

Here is the code I used for all 3 tasks to pass without the import:

User.m 
#import "User.h"
#import "Treehouse.h"

@implementation User

- (instancetype)init
{
    self = [super init];
    if (self) {
        Treehouse *treehouse = [[Treehouse alloc] init];
        NSDictionary *friendsDict = treehouse.friends;

        _firstName = [friendsDict objectForKey:@"firstName"];
        _lastName = [friendsDict objectForKey:@"lastName"];


        //Task 1

      _profileImageName = [friendsDict objectForKey:@"profilePicture"];

        //Task 2

      _profileImage = [UIImage imageNamed:_profileImageName];

        //Task 3

      _userProfilePhoto = [[UIImageView alloc] initWithImage:_profileImage];
    }
    return self;
}

@end

I still have this being looked at and hope this will get you back on track in the meantime.

Please let me know if I can be of any further assistance.

Regards,

Chris

Bharath,

It looks like you have found a bug. Your code looks correct to me. I have submitted this to support as it keeps giving the error as you said:

'UIKit/UIKit.h' file not found #import ^ 1 error generated..
