iOS Build a Playlist Browser with Objective-C Working With Multiple View Controllers UIButton Recap

UIButton Recap Challenge 1 of 2; keep getting syntax error, what gives!?

Hi no matter what I do this challenge keeps throwing back a compiler syntax error. I believe this may be a bug as I don't actually receive an error in Xcode itself. I tried writing the solution in Obj-C and Swift to no avail.

Challenge Task 1 of 2: Let’s assume we have an IBOutlet of type UIButton, named timerButton, as a property in our view controller header file. In the implementation file, set the title of the button to “Start!” for the state configuration UIControlStateNormal. Hint: Check out the UIButton class reference in the documentation.

ViewController.h 
#import "UIViewController.h"
#import "UIButton.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) IBOutlet UIButton *timerButton;

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

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    UIColor *redColor = [UIColor redColor];

    // Enter your code below!
    [self.timerButton setTitle:@"Start!" forState:UIControlStateNormal];


}


@end

 [self.timerButton setTitle:@"Start!" forState:UIControlStateNormal];

That's what I did and it worked, not sure what is going on for you.

At the time that this was posted there was a bug with the compiler for Objective-C. Challenge was correct :)
