Xcode

Xcode 4.3.2 instability. Is it just me?

Since a couple of weeks I am experiencing many crashes of the Xcode IDE, for whatever reason. I tried reinstalling, I tried rebooting I tried cleaning my projects, creating new ones, nothing worked. Besides, the Simulator is no longer usable, keeps longing while attaching to process…I am wondering if this is just me or the Xcode development is getting worse. Any hints out there?

EDIT: Turns out it was me, not Xcode, as soon as I moved to my new Macbook Pro 15″, Xcode started working again the usual way. I am very glad of that.

Objective-C

A Motivation for ivar decorations

If you have the time, read this interesting article on Big Nerd Ranch Weblog on why using underscores for instance variables. I totally agree with Mark Dalrymple, whom I thank for having expressed in a clear way what has been buzzing in my head for quite a while.

Multiple -fno-objc-arc ….alleluja!

Ever had to flag many files with the -fno-objc-arc flag to integrate them into an ARC enabled project? I did (and I do). What a pain when they were many. Finally I got onto this page and I have seen the light.

The solution is to select multiple files, hit enter (not double-click), put in the -fno-objc-arc flag, hit enter again. You’ll see that all your selected files now have the flag set.

Thank you guys, really.
