facade's Issues

Rounded UIImageView not showing

Hello,

I'm using

    self.imagerView = [UIImageView new];
    self.imagerView.layer.cornerRadius = self.imagerView.frame.size.width / 2;
    self.imagerView.clipsToBounds = YES;
    [self.containerView addSubview:self.imagerView];

and

[self.imagerView anchorTopLeftWithLeftPadding:10 topPadding:10 width:50 height:50];

But UIimageView is not rounding as expected.

Please advise.

Carthage compatibility

https://github.com/Carthage/Carthage

Currently it says "Dependency "Facade" has no shared framework schemes", so we need create framework and share its schema.

Using it in UITableViewCell

Hello,

Love your project. Can I use this category in a UITableViewCell?

What to do in times of UIStackView?

Hey @mamaral

how are you? I just stumbled upon your Project and it looks really cool. But Apple announced UIStackView and i am asking myself what the advantage is, using Facaded in comparisson to Apples Solution.

Here's a Swift Implementation!

Here's a SWIFT implementation!
It may need some optimization love, but should be 100% compliant to modern SWIFT libs.
(Anything Doubles Related needs looking into for perf sake at least.)

Animations of a group or a view

Is it possible to apply animations to a group as a whole, and/or apply an animation block to a group such that each view inside will use it?

Or all views should just be treated regularly?
