[Tap to Pay] Reader connection - location permission result not awaited

[TomaszLizer]

Summary

When connecting to the reader location services access is required. During connection flow location access request popup is presented. Nevertheless after popup is presented flow continues without awaiting for the request result. This causes several issue with payment flow:

• Since location request ought to be performed in response to user action we cannot reliably connect to the reader in background (as requested by Apple)
• We are connecting to the reader in payment flow - in this case SDK does not wait for location permissions and continues returning connection success. Subsequent payment made with connected reader will fail due to missing location.

Since location is required for the reader to work and location permissions are handled by SDK it should await for permission to be granted before continuing and throw error in case permissions were rejected by the user.

Currently SDK returns value from connectReader without respecting result or lack of for location permission dialog.

Code to reproduce

let config = try TapToPayConnectionConfigurationBuilder(delegate: reporter, locationId: locationId)
    .setTosAcceptancePermitted(canAcceptTos)
    .build()
let connectedReader = try await terminal.connectReader(
    discoveredReader,
    connectionConfig: config
)
