you need to put your if statement AFTER the BOOL, you have yours before it and have the bool inside the if. you need to start the if after the line BOOL isCorrect = [GuessEngine testGuess:userNumber]; since that BOOL value is used to as the conditional in the if statement

#import "NumberGuesserViewController.h"
#import "GuessEngine.h"
#import "UIAlertView.h"

@implementation NumberGuesserViewController

- (IBAction)makeGuess:(id)sender {
    NSString *userNumber = self.numberField.text;

    // Check to see if the user's number is correct
    BOOL isCorrect = [GuessEngine testGuess:userNumber];

//put it after
    if (isCorrect == YES) {
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Hooray!" 
     message:@"You did it!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

     [alertView show];

     }
}

Challenge task 3 of 4 If the guess is correct, we want to alert the user with a message using a UIAlertView. Add an if statement that checks if the BOOL variable 'isCorrect' is true (or 'YES'). Inside the if statement, declare a new UIAlertView variable named 'alertView'. Alloc/init it with the method 'initWithTitle:message:delegate:cancelButtonTitle:otherButtonTitles'. For the title, use "Hooray!", for the message, use "You did it!", for the delegate use nil, for cancelButtonTitle use "OK", and for otherButtonTitles use nil.
