Where can I find the information of writing this project?

[newlife]

for example ,how to write the manifest.json and signature files?

Check out the PassPackager, there you will find that the manifest and signature files are created.

actually ,I want to know the format of this, or criterion?

I am not sure what you mean, but I guess you are looking for the specification to which this repo was written.
I created this based on the docs supplied by Apple:
Pass Design and Creation
