Can anybody help me understanding this Autolayout exception?
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. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the
UIView property translatesAutoresizingMaskIntoConstraints)

Whatever the view is that you're adding in code you should add the line...
imageView.translatesAutoresizingMaskIntoConstraints = NO;

As i posted in this GitHub issue, I am having trouble with some hidden constraints that throw an error whenever I try to add my own constraints

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.`
I have tried looking for the places that these constraints could have been created, but searching my ViewController.swift file for keywords such as constraint, layout .etc turned up only the code that I wrote.
My code is all on GitHub if anyone wants to mess around with it.
If you are going to add constraints programmatically, you need to turn off translateAutoresizingMaskIntoConstraints. You also don't have enough constraints to satisfy the layout engine. Remember that UIView's don't have an intrinsic size and if you are using auto layout with a view you need to set everything with constraints and not rely on a mixture of constraints and frames. one possible solution is to add some code like:
self.view.addSubview(clockView)
clockView.translatesAutoresizingMaskIntoConstraints = false
clockView.centerYAnchor.constraintEqualToAnchor(self.view.centerYAnchor, constant: 0.0).active = true
clockView.centerXAnchor.constraintEqualToAnchor(self.view.centerXAnchor, constant: 0.0).active = true
clockView.widthAnchor.constraintEqualToConstant(230.0).active = true
clockView.heightAnchor.constraintEqualToConstant(230.0).active = true
However this is not exactly what you want as when it is in landscape your clock overlays your label. But you could fix that by playing with clockView.centerYAnchor.constraintEqualToAnchor(self.view.centerYAnchor, constant: 0.0).active = true
Hiii Guys,
I have a view with 600*450 size, now i put a collection view in a view with 600*430 size. when i am running application i am getting this weird message on console

i don't know what to do.
I have applied this 4 constraints to UICollectionView.
This occur because few constraint you have added is not required so it is better to select the view and then after Choose Reset to suggested constraint .
and if after this if constraint not up to mark then better to look for each control constraint and check which constraint showing mark (yellow)and try to remove manually and then add.
Hope it helps.
I am constantly getting this error:

How can I detect the views whose constraints are being unsatisfied?
[UILabel:0x14641060]
It's in error message.
It seems this UILabel has three constraints. Remove any one of these you can satisfy the constraints
I've seen the common response to this question of not having constraints set up properly. However, I've worked through all of the ambiguities in Interface Builder, and all constraints seem OK. I'm not sure what to check next. I can't even tell where it is coming from. I'm not setting any constraints in code.
What can I do to figure out where it is coming form?
What can be the cause if Interface Builder doesn't report any ambiguities?
Here's the specific error:

I know the two place in code where I have a UIImageView constrained to 20x20, but again, IB tells me everything is fine.
This is the part where the problem is:
<NSAutoresizingMaskLayoutConstraint:0x170286d60 h=--& v=--& H:[UITableViewCellContentView:0x178166840(247)]>
This mask needs to be turned off.
I think that mask is off by default for IB elements that have constraints. So I assume you made something in code. You can turn it off in code like this:
contentView.translatesAutoresizingMaskIntoConstraints = NO
If this is really all IB only then I would like to know what code you use around creating table cells.
I have this warning when building my app. I'm using a storyboard, but all constraints are proper over there.. I don't know where else I have to look..
