• iOS weird error: dyld: Symbol not found: __dealloc? 4 answers

I cann't start my IOS simulator 7.1 after i update my Xcode into latest version 5.1, and OS X to 10.9.5 When i start the build and run, it shows the build is successful, no issues found. But debug output have this message.

dyld: Symbol not found: __dealloc
  Referenced from: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
  Expected in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/usr/lib/libobjc.A.dylib

dyld`dyld_fatal_error: 
0x8fe440b4:  int3    
0x8fe440b5:  nop 

Anyone who know the reason about this issue? i cannt go ahead to do my simulator deployment, and don't know where to go now.

My environment context is as below:

Issues configuration, looks the iOS 7.1 didn't work well with Simulator 6.1 and 7.1.

After update the iOS 8.1, Simulator 8.1, the Symbol not found issue is gone now.Poor quality tools, cause me tons of time investigating on such issues!
