Error while installing private cocopods library in iOS app

My podspec as follow,

Pod::Spec.new do |s|  s.name             = 'demo'  s.version          = '0.1.0'  s.summary          = 'A short description of demo.'  s.description      = 'This is a pob library'  s.homepage         = 'https://mygitrepo.git'  s.license          = { :type => 'MIT', :file => 'LICENSE' }  s.author           = { 'authorName' => 'authorName@demo.com' }  s.source           = { :git => 'https://mygitrepo.git', :branch =>'dev/demo' , :tag => s.version.to_s }  s.source_files = 'demo/Classes/**/*.{h,m,swift}'  s.vendored_frameworks = 'Example/Pods/testFramework.framework'end

I created own private cocoapods dependency library : source. I added few Objective-C classes .h/.m and swift file. After that I push my code into git.

XCode build phases as follow,

I'm getting .h file not .m or swift files.

I added this dependencies in my project in the pod directory but I not getting .m and .swift files.

Pod structure in the main project as follow,

.m file not found after installing pod dependency.
