I upgraded to Mavericks
and installed Xcode 5.0.1
.
I opened one of my projects, which targets 10.6, and declined the option to upgrade to "Upgrade to take advantage of Xcode 5 features?" which mentioned Auto layout.
Now 2 of my xib files have errors (the other 12 seem OK):-
error: Illegal Configuration: Auto Layout on OS X prior to 10.7
warning: Attribute Unavailable: Identifier on OS X versions prior to 10.7
Attribute Unavailable: Automatically Recalculates Cell Size on OS X versions prior to 10.8 - 0n NSMatrix
How can I delete the constraints?
