How to debug AutoLayout Constraints?
<p>I am new to iOS Development. Whenever I run my App, I get this conflicting constraints error. Can you please suggest me something about how to debug this issue?</p>

    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. 
(
    "&lt;_UILayoutSupportConstraint:0x7fcaf3c5e670 V:[_UILayoutGuide:0x7fcaf3c62a80(0)]&gt;",
    "&lt;_UILayoutSupportConstraint:0x7fcaf3c5c060 _UILayoutGuide:0x7fcaf3c62a80.bottom == UIView:0x7fcaf3c54390.bottom&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c54b00 UIImageView:0x7fcaf3c54c70.width == UIImageView:0x7fcaf3c54c70.height&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c633d0 V:|-(0)-[UIImageView:0x7fcaf3c54c70]   (Names: '|':UIView:0x7fcaf3c54390 )&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c63420 H:[UIImageView:0x7fcaf3c54c70]-(0)-|   (Names: '|':UIView:0x7fcaf3c54390 )&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c63470 H:|-(0)-[UIImageView:0x7fcaf3c54c70]   (Names: '|':UIView:0x7fcaf3c54390 )&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c63560 V:[UIImageView:0x7fcaf3c54c70]-(0)-[_UILayoutGuide:0x7fcaf3c62a80]&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c67e50 'UIView-Encapsulated-Layout-Height' V:[UIView:0x7fcaf3c54390(736)]&gt;",
    "&lt;NSLayoutConstraint:0x7fcaf3c61230 'UIView-Encapsulated-Layout-Width' H:[UIView:0x7fcaf3c54390(414)]&gt;"
)

Will attempt to recover by breaking constraint 
&lt;NSLayoutConstraint:0x7fcaf3c54b00 UIImageView:0x7fcaf3c54c70.width == UIImageView:0x7fcaf3c54c70.height&gt;

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in &lt;UIKit/UIView.h&gt; may also be helpful.
