Error while doing lint command on private pod "Encountered an unknown error (no implicit conversion of nil into String) during validation."

Question

I'm creating a private pod depending on another private pod the linter works well when I don't add any dependency but when I add the dependency and run the lint command it gives me that error

Encountered an unknown error (no implicit conversion of nil into String) during validation.

the lint commmand:

pod spec lint --private --sources=https://github.com/*****/****.git

Here is my podSpec what is wrong with it and what should I do to fix that?

Pod::Spec.new do |s|

s.name         = "****Framework"
s.version      = "1.0.0"
s.summary      = "Summary  ................."
s.homepage     = "https://github.com/****/****Framework"
s.description  = "Description ................."
s.license      = "Simplified BSD license"
s.author       = { "Nahla Mortada" => "nahla.mortada@****.com" }
s.platform     = :ios, "9.0"
s.ios.deployment_target = "9.0"
s.source   = { :git => "https://github.com/****/****Framework.git", :tag => s.version }
s.source_files = "****Framework/*.swift"
s.pod_target_xcconfig =  {
'SWIFT_VERSION' => '3.0',
}
s.requires_arc = true
s.dependency '****'

end

updated the question but still don't understand what's wrong — nahlamortada, Jul 05 '17 at 14:03
The dependency which is private is supposed to be where exactly? A private repo? Did you try to add ":git" or something like that? Because if it's private an unknown, it still need to fetch it. Maybe look there: https://stackoverflow.com/questions/16905112/cocoapods-dependency-in-pod-spec-not-working — Larme, Jul 06 '17 at 12:38

Try clearing your local CocoaPods cache by running rm -rf ~/.cocoapods and then running pod setup.

Your podspec appears to be valid, if this doesn't help you should try uncommenting your s.dependency und linting it again, because the dependency-pod might also be the one causing this crash.

Yes it is the one doing that but the dependency pod is valid and we use it in different projects. I did what you said and still the same error – nahlamortada Jul 06 '17 at 00:00
