Compile errors on storyboard after upgrade Xcode to 6.3

Question

The storyboard file was previously created with Xcode6.0, after upgraded Xcode to 6.3. Compile errors jumps out with obscure error messages. I have spent hours on searching but still haven't figure out what/where exactly the problematical items are on my storyboard file.

Thanks a lot in advance for your time/suggestions, etc.

Below are the full error message:

Answer 1

Finally worked the problem out with an doable(although, not efficient) approach:

Narrow down scope thus to locate the problematical view scene by removing other view scenes from storyboard, in a "binary search" way.

After identified the problematical view, I re-setup the views and its constraints. Then, Build Succeeded.

Share it here for that it may be useful to somebody else.

Answer 2

This will happen if you try to add constraints to views that are not within the view hierachy. An auto layout restriction.

I stayed using Xcode 6.3 and did the following:

I worked out which programmatically created constraint was causing the issue (by running through the code in debug and seeing when crash occurred). Then I debugged to this point and checked neither of the 2 views within the constraint were null when the constraint was added. One of them was. I fixed this and the error went.

Answer 3

This is how I resolved the problem: I copied the storyboard file to my Windows machine and wrote a small C# program with Linq to XML to find the bogus constraint, which has the "firstItem" attribute but missing the "secondItem" attribute. Basically it is just one line:

        var nosecondCons = xdoc.Descendants("constraint").Where(p => p.Attribute("secondItem") == null && p.Attribute("firstItem") != null);
