How do I use initWithImage: method?

The code seems to have no errors, but it stills says I am getting something wrong.

Treehouse.h 
#import <Foundation/Foundation.h>

@interface Treehouse : NSObject

@property (strong, nonatomic) NSDictionary *friends;

@end
Treehouse.m 
#import "Treehouse.h"

@implementation Treehouse

- (instancetype)init
{
    self = [super init];
    if (self) {
        _friends = @{@"firstName": @"Susan",
                     @"lastName": @"Olson",
                     @"profilePicture": @"susan_profile.png"
                     };
    }
    return self;
}



@end
User.h 
#import <Foundation/Foundation.h>

@interface User : NSObject

@property (nonatomic, strong) NSString *firstName;
@property (nonatomic, strong) NSString *lastName;
@property (nonatomic, strong) NSString *profileImageName;
@property (nonatomic, strong) UIImage * profileImage;
@property (nonatomic, strong) UIImageView *userProfilePhoto;

@end
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"];

        _profileImageName = [friendsDict objectForKey:@"profilePicture"];
        _profileImage = [UIImage imageNamed:_profileImageName];
        _userProfilePhoto = [ ((UIImageView *)[UIImage alloc]) initWithImage:_profileImage];
    }
    return self;
}

@end

Never mind, I solved the problem with:

_profileImageName = [friendsDict objectForKey:@"profilePicture"];
        _profileImage = [UIImage imageNamed:_profileImageName];
        _userProfilePhoto = [ [UIImageView alloc]) initWithImage:_profileImage];
