Error Handling

While using the UniPass SDK, errors may be thrown. In order to handle errors more gracefully, the relevant errors are defined as follows:

public enum UniPassError: Error {
    case noBundleIdentifierFound
    case userNotLogin
    case userCancelled(msg: String?)
    case appCancelled
    case invalidFromAddress
    case invalidTransaction
    case unknownError
    case runtimeError(msg: String)
    case decodingError
    case encodingError
}

Error	Parameter	Description
