Swift error with NSContiguousString frame

Hey, I'm having issues setting up the slider with swift.

     let listSlider = CategorySliderView.init(frame: CGRectMake(0 , 0, 60, self.view.frame.width),
            andCategoryViews: List.getAll(),
            sliderDirection: SliderDirection.Horizontal,
            categorySelectionBlock: { (categoryView: UIView!, index: Int) -> Void in
                print("index: \(index)")
        })

        let listSlider = CategorySliderView(sliderHeight: 60.0,
            andCategoryViews: List.getAll()) { (categoryView: UIView!, index: Int) -> Void in
                print("index: \(index)")
        }

Either way, I'm getting the error I'm getting below:

How would you recommend to set up the slider in swift?

Updating Buttons

If the user needs updated buttons showing x followers each time the user enters his/hers profile and that x value is fetched async from the web in viewWillAppear, how can you then update the button with the value x when the callback comes in?
In other words, how can you update the buttons after they first have been laid out?

Thank you for your time

Swift Code

Hi, I've been trying to translate this tiny part of code into Swift.. can someone help?

CategorySliderView *sliderView = [[CategorySliderView alloc] initWithSliderHeight:60 andCategoryViews:@[category1, category2, category3] categorySelectionBlock:^(UIView *categoryView, NSInteger categoryIndex) {
UILabel *selectedView = (UILabel *)categoryView;
NSLog(@""%@" cateogry selected at index %d", selectedView.text, categoryIndex);
}];

Setting backgroundColor

Hi,

I'm unable to set the backgroundColor of an initialized CategorySliderView. This code doesn't work and the view still has a yellow background, is there a trick to setting the background color or am I missing something?

[self.sliderView setBackgroundColor:[UIColor redColor]];

I found where this is hardcoded to yellow in the .m file, would you take a pull request to add setting the bgColor to the initWithFrame.... initializer like:

- (instancetype)initWithFrame:(CGRect)frame andCategoryViews:(NSArray *)categoryViews sliderDirection:(SliderDirection)direction categorySelectionBlock:(categorySelected)block withBackgroudColor:(UIColor *)bgColor;

EDIT:
I discovered that if I remove line 53: https://github.com/cemolcay/CategorySliderView/blob/master/CategorySliderView/CategorySliderView.m#L53
I'm able to set the backgroundColor in my instantiated CategorySlider. I'm happy to create a pull request to remove the [self.scrollView setBackgroundColor:[UIColor yellowColor]]; line and/or create an initializer. Let me know if you have a preference
