Autolayout issue Xcode 8 [_SwiftValue nsli_superitem] : <p>Converting my code to Swift 3 I found a weird issue.
Right now (15th September 2016) Xcode 8 (public version) is out, and after converting the code, my App crashes without an apparently reason.</p>

<p>There is something wrong with Auto Layout and the log says something like:</p>

<pre><code>[_SwiftValue nsli_superitem]: unrecognized selector sent to instance 
</code></pre>

<p>How can I solve? Thanks</p>
