Honestly, I could not rebuild all object files so quickly, I don't have all sources )<br>
But we will try.<br>

Right now yes, I could reproduce it only with LTO,<br>
<br>
but one half year ago we faced with the same issue w/o using LTO,<br>
it was solved just moved protocol declaration like that:<br>
<br>
<div>+@protocol MDLComponent <NSObject><br>
+@end<br>
+<br>
<br>
@protocol MDLObjectContainerComponent <MDLComponent, NSFastEnumeration><br>
