I`m with problems when use visa checkout sdk for ios. Use o xcode 9.1, iphone 6s. On simulator this crash not happens. The crash only happens in device, when touch on visaButtonCheckout to checkout, its crash saying:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[LAContext biometryType]: unrecognized selector sent to instance 0x1c087b8c0'
