Pod回购推送在iOS中不工作

我已经创建了CocoaPod示例文件,并成功运行,现在正处于最后阶段,当我执行Pod Repo时,推送它显示错误。下面是我收到的命令和错误。

Pod::Spec.new do |s|
s.name         = "IDFVSample"
s.version      = "1.0.0"
s.summary      = "A short description of VFIDOneFramework. Please check this awesome work from me you will like it"
s.description  = "This is the best tutorial. Recently given presentation in the world great forum for the member."
s.homepage     = "https://github.com/kashiftriffort/IDFVSample"
s.license      = "MIT"
s.author       = { "KJilani" => "Kashif.triffort@gmail.com" }
s.platform     = :ios, "9.0"
s.source       = { :git => "https://github.com/kashiftriffort/IDFVSample.git", :tag => "1.0.0" }
s.source_files = "IDFVSample/IDFVSample/IDFVSample.swift"
s.dependency 'Firebase/Core'
end

pod repo push IDFVPodSpecs IDFVSample.podspec --allow-warnings
