Well that’s that. The Xcode 4 book is finished and currently being printed (and prepared for digital sale in a number of formats as well). You can preorder it now if you like. See the official announcement for (un)specific dates.
Continue readingPer-File Compiler Flags in Xcode 4
I had written previously (twice) about missing debug symbols and strangeness related to compiler optimization in Xcode. I’d specifically mentioned per-file compiler flags. You may be wondering where they went in Xcode 4. “Ur flagz … let me show you them.”

Another quick Xcode debugging tip: If you experience “orange breakpoints” when debugging and have verified you’re in debug mode, and have cleaned and rebuilt your target to no avail, try disabling “Load Symbols Lazily” in Xcode’s Debugging preferences panel.
Just Lettin’ You Know
Several people have asked me privately to let them know when the book comes out. It seems e-mail is the preferred method for those who (for reasons I can’t possibly fathom) don’t feel like keeping up with the Social Web. So I created a mailing list for the Xcode 4 Book site.

I figured I’d share a more complete post on the subject of buggered debuggers for the most common causes.

I’ve just completed a 16-hour (off and on) “what the fuck?!” session with Xcode (3 and 4). Specifically, when debugging a specific class, gdb kept telling me, “Unable to access variable…” any time I’d “po” a variable or hover over the symbol in the editor. I blamed plenty of different possible culprits.
