So, someone will probably beat me over the head for asking this, but shouldn't apps built on 10.3 run on 10.2? So I've been doing some development work on the preview release of 10.3, and I'm finally getting used to Xcode and it's "differences" from Project Builder (it took me forever to find the console log). Anyway, I know that the developer preview shouldn't be used for hard core development practices and everything, but why wouldn't an app I wrote in 10.3 run in 10.2? From my console log, it seems that there's an issue in the nib format...

Here's my error log:

I don't think I've ever seen my code cause a stack trace that goes back 88 levels before!

Thanks (please don't be too harsh!

XCode comes with some stuff to target 10.1/10.2

[Devin Lane]

10.3 introduces a lot of new things, especially in the nib files. Keyed archiving, new contorolls, and NSObjectController are just some of them. Also, there are many new methods available in 10.3 that are not in 10.2. You can, however use the 10.2 SDK as suggested by Catfish_Man, or make sure to save your nib in 10.2 format and not use any of the new 10.3 features.

[Angus_D]

Keyed archiving was new in 10.2, no?

[Ghoser777]

Keyed Archiving was new in 10.2, not 10.3. I changed the project settings to build against the 10.2.6 SDK instead of the 10.3 SDK, but that didn't solve the problem (it took forever to figure out how to do this in Xcode). In Interface Builder, I made sure my nib files were being saved in... the 10.2 and after format (there is no 10.2 only option). According to IB, there are no problems with my nib files that should be caused by loading them on 10.2 (the consistency checker). Still... the problem remains.

Grrrr...

Wow, here's the problem:

I nested an NSMatrix of NSButtons inside an NSBox inside an NSTabViewItem inside an NSTabView inside an NSView inside an NSWindow and it didn't seem to like it. Removing the matrix and moving my nib file to a 10.2.3 machine allowed me to open it up and build my project for 10.2.x. Other NSMatrix's in other parts of my nib file didn't cause the same problem. Deleting and recreating the matrix where it was didn't fix it. There's something bad about that nesting. Go figure.

Thanks!

Hmm... sounds like the old ?NESTING TOO DEEP ERROR or some such you got back in Applesoft BASIC when you nested more than 16 FOR...NEXT loops... there was only a certain amount of stack space allocated for that sort of thing. Maybe the same thing is happening here too.

Just speculating.
