Pod install GPUImage does not work

it's my bad, i got the solution:

You then need to add a new Copy Files build phase, set the Destination to Frameworks, and add the GPUImage.framework build product to that. This will allow the framework to be bundled with your application (otherwise, you'll see cryptic "dyld: Library not loaded: @rpath/GPUImage.framework/GPUImage" errors on execution).

I had the same issue with the following library versions:

• Xcode 6.3
• Cocoapods 0.37.2

Finally I solved this issue by the following steps:

First step:

1. Open Xcode
2. Click Window (Menu Bar)
3. Click Projects
4. Remove all projects (e.g. use backspace)
5. Close Xcode

Second Step:

1. Open a terminal app
2. cd ~/Library/Developer/Xcode/DerivedData
3. rm -rf Build/* see below if you have a customized build location
4. rm -rf ModuleCache/*
5. Close a terminal app

Third Step:

1. Open Xcode
2. Product > Clean
3. Product > Run

If you have defined a custom build location:

1. Go with Finder or the Terminal to the location of the build files. The location for these files is defined in Xcode. To check where these files are:
   • Open Xcode
   • Go to Settings -> Locations -> Derived Data
2. Go to that location and delete the Build folder

Then everything work well.

Hope this can help somebody in the future.
