  • The error returned when a license key is not supplied, is invalid, or is expired. A valid license key must be provided to use some classes including the reader and the resolver classes.

    Declaration

    DMSInvalidLicense

    Swift

    case invalidLicense = 1

  • The supplied Metal device is incompatible with this detector. The device may not have the minimum required set of capabilities. Try a different device, pass a nil value to use a CPU based detection, or don’t pass this option to let DMSDK find the best Metal device.

    Declaration

    Objective-C

    DMSReaderMetalDeviceIncompatible = 1

  • The reader options supplied to the initializer are not valid.
