Hello,
The appearance of one of my buttons is not updating after being tapped. I have had no trouble doing the exact same thing in my other views, but here it simply doesn't work. The "heart" button will keep its original appearance (in this case an unfilled heart) no matter what, despite my print statements indicating that the value has changed. The other actions performed when tapping the heart work perfectly. I've been at it for hours.
Any help would be appreciated. Thanks!
