Error comes while project opens in Xcode

My unity project creates error while opens in Xcode.

The error is

clang: error: linker command failed with exit code 1 
(use -v to see invocation)

So i cant able to open in xcode.

Xcode Version : xcode5.0

Unity Version : unity4.0

How can i escape from this issue?

Here’s the solution:

  1. In Xcode, click your target and open Build Settings
  2. Find Library Search Paths and remove everything in there
  3. Right-click libiPhone-lib.a in the Libraries folder and click Delete
  4. Click Remove Reference in the pop-up
  5. Right-click the Libraries folder in Xcode and click Add Files to … (CMD + Option + A)
  6. Select the libiPhone-lib.a file which is in the Libraries folder on your hard drive and add it

This auto-creates a new URL in the Library Search Paths entry and should make the Linker error disappear.
