Sydney

Sydney is a jailbreak tweak designed and developed by Bank5ia, that creates a range of customisation options for any Apple Pay cards (also known as a Payment Pass) found within the users Wallet app.

Gathering payment pass information
This is needed to display the users passes within Sydney's preferences and for other reasons.

Working Dynamically
Sydney needed to support an infinite amount of Apple Pay cards, so Sydney needed to work dynamically.

Validating
Validation is used within Sydney to stop the user from entering un-supported text or customising un-supported cards.
