In fact, if there were properties set in the file that didn't match what IB presented...I'd rollback, ensure the issue still exists, and submit a bug report to Apple. That doesn't sound good.

I realized that the nib compiler was giving me warning for the new UILabel setting "Tighten Letter Spacing". Fine, so I turned it off, saved the file and recompiled. Got the same warnings! So, I double-checked everything and no check box checked but compiling gave still the same warning.

The problem is that the nib compiler would complain that letter spacing adjustment was not available prior to 6.0 even though I couldn't find any UILabel or UITextField that had this setting turned on. I had to use a text editor to remove those instances that were set to YES.

Well, that isn't a very satisfying explanation (if it's an explanation at all). I created a new project with a UILabel and set the letter spacing adjustment, and I was able to run on the 5.1 simulator with no crash and no warning. So what explains this difference in our outcomes? How can I reproduce your results? m.
