supportedRegions
An array of regions that describe the locations to support.
Declaration
var supportedRegions: [Locale.Region]? { get set }Discussion
If you provide this array, the system filters the selectable payment passes to those the payment service providers (PSP) issued in the supported regions. Indicate the supported countries or regions by using Locale.Region structures that represent the ISO 3166 country codes to filter.
The ordering of the elements you provide doesn’t affect the filtering of the cards. For example, debit cards may expect transactions only in the country or region of issuance for the card.
The supported countries or regions list doesn’t affect the currency of the transaction.
For more information on region codes, see ISO 3166.
