ld: file not found: linker command failed with exit code 1

Question

I've got the following error when building the project in Xcode:

ld: file not found

/Users/MacBookPro/Library/Developer/Xcode/DerivedData/Social_Events-cfnteabiivwfdzcoulzznhmgobhy/Build/Products/Debug-iphoneos/Social_Events.app/Social_Events clang: error: linker command failed with exit code 1 (use -v to see invocation)

I'm stuck with this error for the past hour.. Any solutions? Code worked fine in iOS 7 and xCode 5.0. Now for iOS8 it gives me this error.

Using frameworks:

• CoreTelephony
• Mapkit
• Facebook.SDK v3.20
• Foundation
• CoreGraphics
• UIKit Framework

Answer 1

You might be getting this error because you renamed your project and Tests cannot be found anymore. This is easy to fix:

Solve it in Xcode like this:

1. Select your project from the project navigator.
2. Select [Your project's Tests] under targets
3. Under General tab change the Host Application from the drop down
4. Build and run.

This problem happened to me because I renamed my project and the tests could't find it anymore.
