title: iOS: How to convert raw file into .pkpass / Sign manifest.json with the pass certificate
body: <p>I'm trying to create a pass to add into apple wallet. I have my file ready and I want to convert the file into .pkPass file.</p>
  
  <p>I tried using 'signinpass' tool from '<a href="https://developer.apple.com/download/more/?name=Passbook" rel="nofollow noreferrer">https://developer.apple.com/download/more/?name=Passbook</a>' and ran on Xcode but i'm not able to generate .pkpass file.</p>
  
  <p>I know that .pkpass is just a zip file so can anyone advise me on how to sign manifest file, which has key/value pair of files and its hashcode with its pass certificate?</p>
