Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1

Question

I am getting following error when I am running my application on iPod touch (version 4.2.1). My app crashes after a point:

Unable to read symbols for /Develope

Answer 1

For some reason just got this in XCODE 4.2. Had to go to

TARGET / BUILD SETTINGS / ALL / SEARCH PATHS / Library Search Paths

And remove the line that somehow had similar entry in the line. Removed it and all is ok

Answer 2

Just delete that folder (/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1), connect your device again, go to the XCode Organizer and it will ask you to collect the symbols from the device. After a couple minutes it will be done collecting and processing the symbols off the device, and you should be good to go.

You can also see this thread for more solutions if this doesn't work.

Answer 3

Sometimes I have similar problems, and what works for me is Clean and Build the target again (without any changes in code!). Strange, but sometimes I had to do it more than once.
