Conflicting Constraint Errors

[MMooreGitHub]

Hi,

1. I'm receiving the following message below when running the example app you provided. Both natively as well as ingested within my app. Also, it's important to note I updated my POD to the latest today and am running ZKCarousel (0.1.5)
2. I setup a symbolic breakpoint and discovered that the offending code is:

ZKCarousel.swift extension UIView {

func **addConstraintsWithFormat**(_ format: String, views: UIView...) {

    var viewsDictionary = [String: UIView]()
    for (index, view) in views.enumerated() {
        let key = "v\(index)"
        viewsDictionary[key] = view
        view.translatesAutoresizingMaskIntoConstraints = false
    }

    **addConstraints(**NSLayoutConstraint.constraints(withVisualFormat: format, options: NSLayoutFormatOptions(), metrics: nil, views: viewsDictionary))
}

}

Also: setup(){ self.addConstraintsWithFormat("V:[v0(43)]-[v1]", views: self.titleLabel, self.descriptionLabel) }

3. I've tested against an iPhone Xs Max and iPhone 6s plus

Error Below: 2018-10-04 14:44:23.392251-0400 ZKCarousel_Example[459:44964] [LayoutConstraints] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( "<NSLayoutConstraint:0x2827c0a50 UILabel:0x105110440.bottom == UILabel:0x105118060.top + 8 (active)>", "<NSLayoutConstraint:0x2827c12c0 V:[UILabel:0x105110440]-(NSSpace(8))-[UILabel:0x105118060] (active)>" )

Will attempt to recover by breaking constraint <NSLayoutConstraint:0x2827c12c0 V:[UILabel:0x105110440]-(NSSpace(8))-[UILabel:0x105118060] (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful. 2018-10-04 14:44:24.892541-0400 ZKCarousel_Example[459:44964] [LayoutConstraints] Unable to simultaneously satisfy constraints.

Thanks for this, I will look into it shortly and confirm if it is a bug.

I've made some changes, run pod update and make sure you are on ZKCarousel 0.1.9. This should fix your issue, but if it persists feel free to open another issue.

Thanks, @ZacharyKhan

I'm still receiving the issue with the latest release (0.1.9). I'll open a new issue.
