Count is unavailable: there is no universally good answer, see the documentation comment for discussion

I receive this error "Count is unavailable: there is no universally good answer, see the documentation comment for discussion" in Request.swift:

    /**
    append the parameters as a HTTP Query string. (e.g. domain.com?first=one&second=two)
    -parameter parameters: The container (array or dictionary) to convert and append to the URL
    */
    public mutating func appendParametersAsQueryString(_ parameters: HTTPParameterProtocol) {
        let queryString = parameters.createPairs(nil).map({ (pair) in
            return pair.escapedValue
        }).joined(separator: "&")
        if let u = self.url , queryString.count > 0 {
            let para = u.query != nil ? "&" : "?"
            self.url = URL(string: "\(u.absoluteString)\(para)\(queryString)")
        }
    }

At queryString.count.
I have installed this with cocoapods.
Can you please help me?

Edit your Podfile like this:

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'MyMoneyV2' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyMoneyV2
  pod 'PKHUD', '~> 4.0'
  pod 'SwiftHTTP', '~> 2.1.0'
  pod 'GRDB.swift', '~> 0.8'
  #pod 'SwiftChart', '~> 0.6.0'
  pod 'Charts', '3.0.0'
  pod 'Eureka', '~> 3'
  target 'MyMoneyV2Tests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'MyMoneyV2UITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

In particular this line:
pod 'SwiftHTTP', '~> 2.1.0'

And then run:

pod install
