I created the my own .pkpass file with dummy data
I need to change the data in the pass according to the data in the app
like boarding pass
if I missed something , could please help me ?
You will require a new .pkpass bundle for every change to the pass.
A new bundle will need to be signed. For security reasons, this should not take place on the device as it risks compromising your Pass Type ID certificate.
When you want to change the data, you should request a new pass bundle from your server and use the PassKit APIs to replace the pass in the Wallet.
You need to implement full loop system according to Apple Passbook/wallet standard or at least you have to like this.
others that: you have to make web service to manage register, update and delete method from devices.
