Summary:

I created a simple app to display the artwork of the current playing song and it runs fine on the device when I Run in Xcode. When I try to profile the app with Xcode, the app launches but no artwork is displayed.

Steps to Reproduce:

1. Create a sample Single View app with Xcode 4.5 DP2.
2. Add the following code to the view controller:

    UIImageView *iv = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,768,768)];
    
    MPMusicPlayerController *player = [MPMusicPlayerController iPodMusicPlayer];
    
    MPMediaItem *item = [player nowPlayingItem];
    
    MPMediaItemArtwork *artwork = [item valueForProperty:MPMediaItemPropertyArtwork];
    
    iv.image = [artwork imageWithSize:CGSizeMake(500,500)];
                      
    [self.view addSubview:iv];

3. Attempt to Profile using Xcode, and select Allocations when Instruments launches.

Expected Results:

Artwork of the current playing song should be displayed on the iPad. (iPad 3 64GB 4G, iOS 6 Beta 2)

Actual Results:

I just see the default white view filling the screen.

I observed the same problem with iOS 6 beta 1 and Xcode 4.5 DP 1.

Regression:

Artwork *is* displayed on an iOS 5 iPad with Xcode 4.3.5.

Note that I have verified that music is playing at the time that I run the app.
