iOS 10 GM with xcode 8 GM causes views to disappear due to roundedCorners & clipsToBounds

Question

I tested my app with iOS 10 Beta 7 and Xcode 8 beta and everything worked fine. However just a few minutes ago I installed the now available GM releases of both and faced a

You could create subclass of your view like this:

@implementation RoundImageView

- (instancetype)initWithCoder:(NSCoder *)coder
{
    self = [super initWithCoder:coder];
    if (self) {
        self.layer.masksToBounds = YES;
        self.layer.cornerRadius = MIN(self.bounds.size.height, self.bounds.size.width)/2;
        [self addObserver:self
               forKeyPath:@"bounds"
                  options:NSKeyValueObservingOptionNew
                  context:(__bridge void * _Nullable)(self)];
    }
    return self;
}

-(void)dealloc
{
    [self removeObserver:self
              forKeyPath:@"bounds"
                 context:(__bridge void * _Nullable)(self)];
}

-(void)observeValueForKeyPath:(NSString *)keyPath
                     ofObject:(id)object
                       change:(NSDictionary *)change
                      context:(void *)context
{
    if(context == (__bridge void * _Nullable)(self) && object == self && [keyPath isEqualToString:@"bounds"])
    {
        self.layer.cornerRadius = MIN(self.bounds.size.height, self.bounds.size.width)/2;
    }
}

@end

so you'll always have properly rounded corners.

I use this approach and hadn't issues upgrading to Xcode8 and iOS10.
