I created a new swift project with PKAddPassButton button only github link
Open settings.
Select General.
Select Language & Region.
Tap Device language and Select "English"/Spanish from the list.
“Add to Apple Wallet” button language doesn't change when the device language is set to another supported language.
Document says “The Add to Apple Wallet button adapts to the device language and the light and dark appearances...”
