DigiMe

public final class DigiMe

The entry point to the SDK

  • Undocumented

    Declaration

    Swift

    public var isDownloadingFiles: Bool { get }

  • The log levels for all DigiMe instances which will be included in logs. Defaults to [.info, .warning, .error, .critical]

    Declaration

    Swift

    public class var logLevels: [LogLevel] { get set }

  • Sets the custom log handler for all DigiMe instances to allow logging to a different system. DigiMeSDK uses NSLog by default.

    Declaration

    Swift

    public class func setLogHandler(_ handler: @escaping LogHandler)

    Parameters

    handler

    The log handler block

  • Initialises a new instance of SDK. A new instance should be created for each contract the app uses

    Declaration

    Swift

    public init(configuration: Configuration)

    Parameters

    configuration

    The configuration which defines this instance

  • Authorizes the contract configured with this digi.me instance to access to a library.

    Requires CallbackService.shared().handleCallback(url:) to be called from appropriate in AppDelegate or SceneDelegateplace so that authorization can complete.

    If the user has not already authorized, will present a view controller in which user consents. If user has already authorized, refreshes the authorization, if necessary (which may require user consent again).

    To authorize this contract to access the same library that another contract has been authorized to access, specify the contract to link to’s credentials. This is useful when a read contract needs to access the same library that a write contract has written deta to.

    Additionally for read contracts:

    • Upon first authorization, can optionally specify a service from which user can log in to and retrieve data.

    • Creates of refreshes a session during which data can be read from library.

    Declaration

    Swift

    public func authorize(credentials: Credentials? = nil, serviceId: Int? = nil, readOptions: ReadOptions? = nil, linkToContractWithCredentials linkCredentials: Credentials? = nil, resultQueue: DispatchQueue = .main, completion: @escaping (Result<Credentials, SDKError>) -> Void)

    Parameters

    credentials

    The existing credentials for the contract to authorize. If nil, will create credentials on success
    serviceId

    Identifier of initial service to add. Only valid for first authorization of read contracts where user has not previously granted consent. Ignored for all subsequent calls.
    readOptions

    Options to filter which data is read from sources for this session. Only used for read contracts.
    linkToContractWithCredentials

    When specified, connects to same library as another contract. Does nothing if user has already authorized this contract.
    resultQueue

    The dispatch queue which the completion block will be called on. Defaults to main dispatch queue.
    completion

    Block called upon authorization completion with new or refreshed credentials, or any errors encountered.

  • Once a user has granted consent, adds an additional service. Also initiates synchronization of data from this service to user’s library.

    Declaration

    Swift

    public func addService(identifier: Int, credentials: Credentials, resultQueue: DispatchQueue = .main, completion: @escaping (Result<Credentials, SDKError>) -> Void)

    Parameters

    identifier

    Identifier of service to add.
    credentials

    The existing credentials for the contract.
    resultQueue

    The dispatch queue which the completion block will be called on. Defaults to main dispatch queue.
    completion

    Block called upon completion with new or refreshed credentials, or any errors encountered

  • Reads the service data source accounts user has added to library related to the configured contract.

    Requires a valid session to have been created, either implicitly by adding a new service, or explicitly by calling requestDataQuery(credentials:readOptions:resultQueue:completion).

    Note: If this is called on either a write-only contract or a contract which reads non-service data, this will return an error.

    Declaration

    Swift

    public func readAccounts(resultQueue: DispatchQueue = .main, completion: @escaping (Result<AccountsInfo, SDKError>) -> Void)

    Parameters

    resultQueue

    The dispatch queue which the completion block will be called on. Defaults to main dispatch queue.
    completion

    Block called upon completion containing either relevant account info, if successful, or an error

  • Fetches content for all the files limited by read options.

    An attempt is made to fetch each requested file and the result of the attempt is passed back via the download handler. As download requests are asynchronous, the download handler may be called concurrently, so the handler implementation should allow for this.

    If this function is called while files are being read, an error denoting this will be immediately returned in the completion block of this subsequent call and will not affect any current calls.

    For reading data written by another contract, it may be necessary for force a new session by calling requestDataQuery(credentials:readOptions:resultQueue:completion) first (and waiting for completion).

    For service-based data sources, will also attempt to retrieve any new data directly from the services, in which case this completion handler will not be called until this synchronization has finished.

    Alternatively, caller can manage reading files themselves by using the calls: requestDataQuery(), readFileList() and readFile()

    Declaration

    Swift

    public func readAllFiles(credentials: Credentials, readOptions: ReadOptions?, resultQueue: DispatchQueue = .main, downloadHandler: @escaping (Result<File, SDKError>) -> Void, completion: @escaping (Result<(FileList, Credentials), SDKError>) -> Void)

    Parameters

    credentials

    The existing credentials for the contract.
    readOptions

    Options to filter which data is read from sources for this session. Only used for read contracts.
    resultQueue

    The dispatch queue which the download handler and completion blocks will be called on. Defaults to main dispatch queue.
    downloadHandler

    Handler called after every file fetch attempt finishes. Either contains the file or an error if fetch failed
    completion

    Block called when fetching all files has completed. Contains final list of files (along with new or refreshed credentials) or an error if reading file list failed

  • Creates a session during which files can be read. This session is typically valid for 15 minutes. Once it has expired, a new session will be required to continue reading data.

    For service-based data sources, will also attempt to retrieve any new data directly from the services.

    Declaration

    Swift

    public func requestDataQuery(credentials: Credentials, readOptions: ReadOptions?, resultQueue: DispatchQueue = .main, completion: @escaping (Result<Credentials, SDKError>) -> Void)

    Parameters

    credentials

    The existing credentials for the contract.
    readOptions

    Options to filter which data is read from sources for this session. Only used for read contracts.
    resultQueue

    The dispatch queue which the download handler and completion blocks will be called on. Defaults to main dispatch queue.
    completion

    Block called upon completion with new or refreshed credentials, or any errors encountered.

  • Retrieves a list of files contained within the user’s library.

    Requires a valid session to have been created, either implicitly by adding a new service, or explicitly by calling requestDataQuery(credentials:readOptions:resultQueue:completion).

    For service-based sources, it can take a while for new data to be added to user’s library (following a requestDataQuery call). Therefore caller should poll this call while data is being added to the library in case new files become available. Synchronization is complete when fileList.status.state.isRunning becomes false.

    Declaration

    Swift

    public func readFileList(resultQueue: DispatchQueue = .main, completion: @escaping (Result<FileList, SDKError>) -> Void)

    Parameters

    resultQueue

    The dispatch queue which the download handler and completion blocks will be called on. Defaults to main dispatch queue.
    completion

    Block called upon completion with the list of files, or any errors encountered.

  • Retrieves the content of a specified file.

    Requires a valid session to have been created, either implicitly by adding a new service, or explicitly by calling requestDataQuery(credentials:readOptions:resultQueue:completion).

    Declaration

    Swift

    public func readFile(fileId: String, resultQueue: DispatchQueue = .main, completion: @escaping (Result<File, SDKError>) -> Void)

    Parameters

    fileId

    The file’s identifier.
    resultQueue

    The dispatch queue which the download handler and completion blocks will be called on. Defaults to main dispatch queue.
    completion

    Block called upon completion with file, or any errors encountered.

  • Deletes the user’s library associated with the configured contract.

    Please note that if multiple contracts are linked to the same library, then deleteUser will also invalidate any credentials for those contracts.

    Declaration

    Swift
