I too got the same error am using xcode version 4.0.2 so what i did was selected the xcode project file and from their i selected the Target option their i could see the app of my project so i clicked on it and went to the build settings option.

Their in the search option i typed Framework search path, and deleted all the settings and then clicked the build button and that worked for me just fine,

Thanks and Regards

If your app is meant to run on the device  make sure you are not trying to run in it on the simulator  May sound obvious  but check anyway

It just happened here to me as well   Thanks to a great partner we found the answer   Your Xcode may be pointing to the simulator   change it to a IOS device instead   built smooth after

I fixed it in a different way The reason why i was getting this error was that i added security framework twice in my project I was not able to see security framework in xcode  i opened the project in finder and found this framework which i deleted and problem solved

I just want to let you know that In my case  I was having the same problem  I realized that I had an older Xcode folder called Xcode3 1 3 I just rename it because it was an older version and that did the magic for me

What has happened here is that Xcode has mysteriously added a  Framework Search Paths  entry that points to a particular iPhone device SDK  For example  mine was recently set to     DEVELOPER DIR  Platforms iPhoneOS platform Developer SDKs iPhoneOS2 2 1 sdk System Library Frameworks   This leads the compiler to find frameworks of the incorrect architecture  Removing any values under the  Framework Search Paths  key in your target s build settings will resolve the issue

I d just experienced something slightly different  because I work on my own library  WM GSRecognizerLib   but the error is the same   What d happen  due to some updates  the path targeting the lib to include   a  was from the  Debug-iphoneos  folder  where it is generated   Compiling for Generic iOS Devices worked fine  but not for simulator  complaining for the missing i386 architecture   What I did for this issue  is to also include the binaries from the  Debug-iphonesimulator  folder   It can help for this topic  because the explanation is here  devices require binaries for arm64 armv7 armv7s  while simulator does need i386

My solution was to set on simulator target debug YES  just look on git status to see the new line added as architecture only on  project  if you don t set this the build will run to all architectures and will show some missing architecture like i386 or other  NOTE THAT obviously the main issue is to use some framework that implements some kind of specific architecture

Check your library search paths in your target settings   Sometimes goofy libraries get entered in there and this will give you a similar error   You can remove all entries in this section

I had this same problem  and the solution turned out to be an easy fix  Backup then open project pbxproj  located inside your project file bundle  in TextMate or TextEdit and search for the section titled     Begin XCBuildConfiguration section      Look for a key named FRAMEWORK SEARCH PATHS and delete it and it s contents  once per build configuration  so I removed it in two places   Here is an example of what I deleted   FRAMEWORK SEARCH PATHS        inherited         DEVELOPER DIR  Platforms iPhoneOS platform Developer SDKs iPhoneOS3 1 sdk System Library Frameworks         My project now build for both the iPhone device and the iPhoneSimulator

Run the file command on the framework from Terminal   file  Developer Platforms iPhoneOS platform Developer SDKs iPhoneOS3 1 sdk System Library  Frameworks UIKit framework UIKit   You should get back a message telling you which architectures the UIKit binary is compatible with  If you don t see  i386  listed  then you ve somehow managed to remove the i386 version of UIKit  which will mean that you can t build for the simulator To fix that  you ll have to re-install the SDK   If you get some other error  hopefully it ll help you figure out what the actual problem is

Though it is possible that something got deleted  it has been my experience that something gets screwed up in the project file   I have yet to pin down what that  something  is  I ve had similar issues when the SDK installation is just fine   There are a couple of options   First  add all of your files to a new project   This seems to usually work   Kind of a pain  though   Second  you can right-click project in XCode Get Info Build Library Search Paths   Add new paths similar to  Developer Platforms iPhoneSimulator platform Developer SDKs iPhoneSimulator3 1 sdk usr lib  Add appropriate versions of that string for each version  2 2 1  etc  and platform  simulator or iPhoneOS   Perform a similar action for Framework Search Paths if frameworks are your problem   Third  which is more work but more reliable  is to open project pbxproj from within MyProject xcodeproj  Textmate is good for this    Look for     Begin XCBuildConfiguration section      then  LIBRARY SEARCH PATHS  and  FRAMEWORK SEARCH PATHS    Add or modify the paths as appropriate  and save the file   In any case  a pain in the butt  and I d sure like to pin-point the cause because I ve had this happen a couple of times   Project builds fine  then just up and refuses to do so with what seems to be little reason

Edit Project Settings  and find  Search Paths  There is a field for  Framework Search Paths   delete all

Check that you didn t copy the framework into your project when you added it  If you copied it  it can t find the original paths  To fix this problem   Delete the AVFoundation framework from your frameworks folder in your project  then add it again  but this time  make sure you don t have copy check marked     This fixed it for me

I just wanted to mention that in XCode if you go to  Edit Project Settings  and find  Search Paths  There is a field for  Framework Search Paths   Updating this should fix the problem  without having to hack the project file    Cheers   Jesse

This happens when you add a framework to your project and unintentionally copy the framework into your project directory   The fix is to check your project directory  where you store your project on disk  for any iphone SDK   Framework files and delete them    Project will build fine afterwards
