  Hi I am having same problem I have tried;

  • http://developer.appcelerator.com/blog/2010/05/titanium-and-iphone-os-4.html

  • Delete ~/Library/Application Support/Titanium then delete all the build/iphone/build directories in your projects. After much frustration this worked for me.

  • Reinstalled titanium, including latest up dates

  My app was working before in version 3.1 but following up grade to SDK 3.2 and 4.0, I cannot even get even kitchen sink to work.

  Quick question has any one else continued to have this trouble. I am confused that some people have been able to resolve this issues and others not using suggested strategies. Is it to do with how I have installed SDK rather than issue in titanium set up , Or should I just remove current 4.0 SDK and go back to earlier versions.

  Any suggestions welcome.

• (dunno why it posted twice)

• I had a lot of issues related to the certificate signing not being exactly right. Don't know if this helps, but thought it might be worth a mention.

• Opening the xcode project file shows foundation.framework isn't found. This is likely to do with Framework search paths wrongly set up. Looking into it…

• bump I'm receiving the same error when attempting to run in the emulator (also not running on device);

  Undefined symbols:
  ".objc_class_name_NSObject", referenced from:
  .objc_class_name_WTIMainThreadCaller in libTiCore.a(MainThreadMac.o)
  ".objc_class_name_NSString", referenced from:
  literal-pointer@OBJC@cls_refs@NSString in libTiCore.a(UnicodeFoundation.o)
  ".objc_class_name_NSCharacterSet", referenced from:
  literal-pointer@OBJC@cls_refs@NSCharacterSet in libTiCore.a(UnicodeFoundation.o)

  Titanium is fully up to date, using Titanium 1.2.1, the project is set up for Titanium SDK 1.30. I've tried compiling with both iOS3.2 and iOS4; I get the same error message regardless of which SDK I use.

  I assumed it was related to something I've done in code (despite knowing this app was working in iOS3.1 on the same machine without issue this morning). To rule this out, I downloaded the latest version of Kitchensink and ran it, only to get exactly the same error again.

  I've reinstalled both the iOS4 SDK and Titanium. No dice.

  I've heard a few whispers about xcode using the wrong SDK or using the wrong path etc. Thoughts?

• (why did it post twice? d'oh)

• After hunting around for ages I finally stumbled across a blog post from May that has a patch.

  I didn't even know there were patches? No mention on the download screen, no "patches" area in the site.
  little sigh - so much time wasted

  This fixed it for me where everything else failed. Good luck :-)

• sorry for the duplicates

• It's great that some of you got it working.
  I recently upgraded to Iphone SDK 4.0 and none of my apps work any more.
  I've done 2 reinstalls to Titanium already and deleted and recreated many projects. Still nothing. The best I could do was to get the ipad simulator to open and showing me a blank project.
  Really frustrating. The error for any project usually is:

  [ERROR] Build Failed. Please see output for more details

  Also already installed the libTiCore.a but nothing changed. Same error all of the time.
  Should I uninstall and reinstall iphone SDK?
