Summary:
On a non retina device, labels always have an integral intrinsic size, while on retina device, depending on the font it might get a decimal size.

Interface Builder seems to assume that it's a retina device, and tries to enforce decimal sizes, but fails to do so correctly (e.g. can't manually set a decimal number in the size inspector), leading usually to misplaced views.

Also, this renders aligning stuff basically impossible, breaks completely existing apps layout, and will create different layouts based on pixel density.

Steps to Reproduce:
Sample code

UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.text = @"Yeah";
[label sizeToFit];
NSLog(@"%f", label.frame.size.height);

Or create a label in IB, setting only top and leading constraints.

Expected Results:
The label height is the same irregardless of the device it's run on

Actual Results:
The label height is different on retina/non-retina devices
