UIProgressView Track Tint Broken?

The UIProgressView track is actually a UIVisualEffectView with a blur effect and can not be tinted.

Is there any reason for

public var trackTintColor: UIColor?

in the UIProgressView class declaration, i.e. is it coming later?

I ran into this too. Luckily it's simple to write your own progress view:

-(void) drawRect: (CGRect)rect
{
    UIColor *progressColor = <whatever color>;
    UIColor *trackColor = <whatever color>;
  
    CGFloat cornerRadius = .5 * rect.size.height;
    UIBezierPath *bez = [UIBezierPath bezierPathWithRoundedRect: rect cornerRadius: cornerRadius];
    [bez addClip];
  
    [trackColor setFill];
    UIRectFill(rect);
  
    [progressColor setFill];
    UIRectFill(CGRectMake(0, 0, ceilf(self.progress * rect.size.width), rect.size.height));
}

-(void) setProgress: (CGFloat)progress
{
    _progress = progress;
    [self setNeedsDisplay];
}

Good solution there! I was hoping we wouldnt have to creat our own, but alas your solution works for me!

Thanks!
