I am trying to use private repositories to break up a larger application. I have followed the guides at:

I have created a local repository to contain the specs, published to cocoapods via

pod remote add MySpecs ~/local/path/to/MySpecs.git,

verified that cocoapods sees them by looking at the contents of ~/.cocoapods/repos/MySpecs

I have referenced PrivateSpec within PrivateClientSpec as follows:

s.dependency 'PrivateSpec' '~> 0.1.0'

The problem is that when I try to lint this PrivateClientSpec, I get the titular error:

Unable to find a specification for [PrivateSpec] depended upon by [PrivateClientSpec]

Am I missing something? From what I understand, this is supported behavior. I am using cocoapods v0.35.

Thanks!

  • my lint passes after adding --sources but the actual pod install fails on the Example project fails. Any idea? Commented Dec 11, 2015 at 3:40

The reason is that the pod spec linter is only checking the master specs, so it can't find your private one.

You'll need to use the --sources option, like this:

pod spec lint --sources='git@our-private-spec-repo:iOS/Specs.git,https://github.com/CocoaPods/Specs'

Two things two note:

  • Your private specs need to be online, can't check on a local one
  • If you depend on other pods you'll need to add the URL for their Spec repo too, that's why in the example we have https://github.com/CocoaPods/Specs too.

By running pod spec lint --help you can read more about this option:

--sources=https://github.com/artsy/Specs   The sources from which to pull
                                           dependant pods (defaults to
                                           https://github.com/CocoaPods/Specs.git).
                                           Multiple sources must be
                                           comma-delimited.

lint --sources='git@our-private-spec-repo:iOS/Specs.git,https://github.com/CocoaPods/Specs' not working pod v0.39.0
This works for the lint, but how about the actual pod install on the Example project of the parent development pod?
As of the latest version of CocoaPods (1.0.1) you can run this without having the specs online using: pod lib lint --sources='git@our-private-spec-repo:iOS/Specs.git,https://github.com/CocoaPods/Specs' --private
this answer should be updated as @MattRobinson pointed out: using the '--private' flag allows to use a private spec.
If you name your repos (through pod repo add) you can also use those names, e.g. --sources='master,our-repo'.

In order for pod install to work properly I still had to add:

source '<Prive specs lib URL>'
source 'https://github.com/CocoaPods/Specs.git'

..to the pod file (not podspec).

To get rid of:

Unable to find a specification for [PrivateSpec] depended upon by [PrivateClientSpec]

Then If you also failed to install with error like this 

pod install --verbose

[!] Your Podfile has had smart quotes sanitised. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice.

Then you should try to update your CocoaPods version. This may help you: //www.greatytc.com/a/39973232/3395008

In case mokagio's answer doesn't work for anyone, here is what worked for me:

Just change private repo url to https://

pod spec lint --sources='https://our-private-spec-repo:iOS/Specs.git,https://github.com/CocoaPods/Specs'

For me the error persisted even after cleaning the cache. The solve was to match the latest tag and latest podspec version. My local podspec version was pointing to an old tag. It worked immediately after those matched.
