search function add_file_references
add if file end wrap the function ;this fix my problem
here is the function modified:

    def add_file_references(file_references, compiler_flags = {})
      file_references.map do |file|
        if file #avoid nil
        extension = File.extname(file.path).downcase

        unless build_file = phase.build_file(file)
          build_file = project.new(PBXBuildFile)
          build_file.file_ref = file

Thanks! it solved my problem!

[rweindl]

Thanks! Also solved the problem for me. I received the error after adding a .xcassets directory to my framework and trying to execute pod install in my example project.

[GouWeiBaCao]

i have the same problem,but i can't resolve it..who can help me @liuqianios ,you can? very thanks

[francos]

I had the same issue and the change suggested by @RayCyder fixed it, thanks!

What is the reason for this error? Why is the file var nil sometimes?

[efalkenberg]

I'm sorry to say that but In my opinion this is a terrible hack. I mean you pretty much ignore the warning instead of fixing the underlying problem and you end up in an unpredictable state.

When i ran into this problem it was mostly caused by an invalid podspec in a pod that I used. Most often there is something like this:
s.source_files = '*/.{h,m}'

Given that you pod structure looks like
/MyPod.posdpec
/MyPod.xcodeproj
/MyPod/MyPod.h
/MyPod/MyPod.m

your podspec has to point to the subfolder with the code in it:
s.source_files = 'MyPod/*/.{h,m}'

[crspybits]

@efalkenberg was on track for me. I had added a new Core Data model to my project and I hadn't accommodated it in the .podspec. Once I did that, I stopped having this problem. I didn't have to use the fix suggested by @RayCyder. In my .podspec, I used:

s.resources = "AppName/Assets/*.xcdatamodeld"

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.

[gabornagyfarkas]

Hi!
Just a side note if somebody stumbles upon this issue on the internet. I had also added a Core Data model to my project and had the same issue. I had the .xcdatamodeld where my source_files pointed. If I moved it outside the path referenced and added it as resources it fixed it.

On CocoaPods 1.4.0, this produces the following error message:

[!] Unable to find other source ref for /Users/eric/Projects/tmp/Fram_iOS_XMPPManager/Pod/Classes/XMPP/Extensions/XEP-0045/CoreDataStorage/XMPPRoom.xcdatamodeld/XMPPRoom.xcdatamodel/contents for target GTIXMPPManager-iOS7.0.

This seems appropriate, as .xcdatamodeld should be add to resources. I think this can be closed
