When I do, pod spec lint, I get following validation error.

Analyzed 1 podspec.

don't know, what is going on here. I followed the instruction step by step.

Here is my spec file:

Pod::Spec.new do |s|

  s.name         = "[Framework-Name]"
  s.version      = "1.0.0"
  s.summary      = "Framework-Name summary"
  s.homepage     = "[Github path for framework]"
  s.license      = "MIT"
  s.author       = { "Author Name" => "[email protected]" }
  s.platform     = :ios, "10.0"
  s.swift_version = "5.0"
  s.source       = { :git => "[Github path for framework].git", :tag => "1.0.0" }
  s.source_files  = "[Framework-Name]/**/*"
  s.exclude_files = "[Framework-Name]/**/*.plist"
end

I couldn't find anything that can help.

The Xcode project files in the podspec's s.source_file expression should only reference the source files.

Xcode project files and other non-source files should not be included.
