What did you do?
I'm creating a framework with this podspec:

Pod::Spec.new do |s|
  s.name             = "elements"
  s.version          = "0.1.0"
  s.summary          = "A short description of elements."
  s.license          = 'MIT'
  s.author           = { "John Nilsen" => "nilsen340@gmail.com" }
  s.source           = { :git => "https://github.com/<GITHUB_USERNAME>/elements.git", :tag => s.version.to_s }

  s.homepage = 'https://github.com/nilsen340/'
  s.platform     = :ios, '8.0'
  s.requires_arc = true

  s.source_files = 'Pod/Classes/**/*'
  s.resource_bundles = {
    'elements' => ['Pod/Classes/**/*']
  }
  s.dependency 'Tapglue', '1.1.0'
end

What did you expect to happen?

It to build the example app correctly

What happened instead?

Can you share a project we can run pod install on that will reproduce the issue? Thanks!

nilsen340 · 2016-02-11T15:09:14Z

https://github.com/tapglue/elements-ios

ui-kit branch

segiddins · 2016-02-23T01:02:02Z

The error I get is as follows, which is unrelated. (using beta 3)

[!] The `elements` pod failed to validate due to 1 error:
    - ERROR | attributes: Missing required attribute `homepage`.
    - WARN  | summary: The summary is not meaningful.

nilsen340 · 2016-02-23T09:11:56Z

@segiddins Sorry, I fixed the homepage issue. If you run pod install now you will get the error from the report

segiddins · 2016-02-23T19:15:22Z

Yup, just reproduced it, thanks!

segiddins · 2016-02-23T21:28:35Z

Issue here is the asset catalogue inside of source files. @efirestone how should we handle that case?

efirestone · 2016-02-23T21:55:48Z

IMO this is a configuration error, although we should handle it more gracefully. It's a configuration error because we're saying that a resource is a source file, which it's not. The easy fix here is to change s.source_files = 'Pod/Classes/**/*' to be something like s.source_files = 'Pod/Classes/**/*.{c,h,hh,m,mm}'.

It looks like pre-1.0.0 this would still just blindly copy assets into the sources phase, which would then fail to build. To get to an equivalent behavior with the new resources handling we should add the nil path handling that's currently in the resources build phase code into the sources build phase code as well.

Another alternative, and this is really a bigger feature, is to provide more understanding of different file types and properly put them into their respective groups (headers, sources, resources, etc). In this world it would recognize that even though a .png file was specified in s.source_files, it's actually a resource and should be added to the resources phase and not the compile phase.

@nilsen340 For the time being, I'd suggest fixing your s.source_files definition. It's incorrect as-is and I don't think would compile even if CocoaPods wasn't crashing.
@segiddins I'd suggest going with the first approach (add nil path handling to the build phase). I can try to look into this later today if you agree with going that direction.

segiddins · 2016-02-23T22:04:48Z

I'm fine with this failing, just as long as it raises an informative error and encourages running pod lib lint, which should catch this

appcoders · 2016-03-31T09:47:37Z

Changing the source_files does not help. I have a private podspec with previously containing

s.source_files = 'SITFinBanks/**/*

I changed this to:

s.source_files = 'SITFinBanks/**/*.{m,h,mm,hpp,cpp,c}'

But still getting the same error on pod spec lint:

I'm having the same issue.

efirestone's answer on Feb 23 fixed the issue for me. I was pulling in a bunch of file that were not source files.

MoinPansare · 2017-05-05T05:55:43Z

hi faced a similar issue
in order to resolve it I needed to move the .xcassets Folder which was created in Classes folder inside the Pod and add it to Assets Folder

Hope this helps someone.

Was this fixed by #6869?

dnkoutso · 2017-11-03T22:04:20Z

best thing to do is clone the sample project and try it!

amorde · 2017-11-03T22:11:55Z

Tried out @nilsen340's project and undid the fix to the Podspec, it now fails with an Unable to find source ref.. error. I think that was the desired behavior 👍
