I don't know how I modified a ios sdk file, but xcode say I did. Here is what they reported. fatal error: file ‘/Applications/Xcode 2.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIFontDescriptor.h‘ has been modified since the precompiled header ‘/Users/m/Library/Developer/Xcode/DerivedData/ModuleCache/24CDWDK5BTYJE/UIKit.pcm‘ was builtnote: after modifying system headers, please delete the module cache at ‘/Users/m/Library/Developer/Xcode/DerivedData/ModuleCache/24CDWDK5BTYJE‘1 error generated.
I tried to look for this deriveddata but cocould not. I also went into organizer to delete it and did a clean, even after that, no luck. How do I restore this uifontdescriptor. h to its original form? IOS xcode

Update: I went into the modulecache and deleted everything, then re-cleaned again, and now it will compile in simulator.-mskw Sep 25' 13 |

Yeah the modules thing isn't fully ironed out yet-you can disable it in the project settings if it becomes a major issue.-Richard J. Ross III Sep 25 '13 |

I have wondered about how you wocould fix this too. But maybe more importantly, why are you allowed to modify header files from the SDK? Didn't use to be able to modify these files in the old days.-Jim merkelsep 25' 13 |

Got to uifontdescriptor. h and undo the changes.-vinodh Sep 25' 13 |

Remove the PCM File
RM "/users/M/library/developer/xcode/deriveddata/modulecache/24cdwdk5btyje/uikit. PCM"
Then
Clean Project (CMD + Shift + k)
Problem solved

I fixed this by deleting the entire contents of the modulecache Folder: cd ~/Library/Developer/Xcode/DerivedData/ModuleCache/rm -rf ./*

You probably didn't CD into the proper directory. Make sure you replace the 'you' with your Mac OS username.-Jamie Forrest Mar 20 |

Your answer is potentially danger. Can you fix it? Like this:cd ~/Library/Developer/Xcode/DerivedData/ModuleCache/ && rm -rf ./*Or like this:rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache/*-K06a Apr 17 at 18:36 |
