# FloatingClient

    @objc(LSFloatingClient)
    class FloatingClient : BaseManager

    extension FloatingClient : CVarArg, CustomDebugStringConvertible, CustomStringConvertible, Equatable, Hashable, NSObjectProtocol

Entry point to the LicenseSpring SDK Class for performing basic requests to LicenseSpring floating server

- `init(configuration:baseStorage:)`

  Init FloatingClient with configuration.

  Throws

  `LSError` if the configuration is invalid or the client cannot be initialized.

  Note

  In Objective-C, pass an instance conforming to the `LSBaseStorage` protocol for `baseStorage`. In Swift, pass an instance conforming to `BaseStorage`.

  #### Declaration

  Swift

      @objc
      init(configuration: Configuration, baseStorage: AnyObject? = nil) throws

  #### Parameters

  `configuration` | Configuration of FloatingClient.
  `baseStorage` | An optional object used for low-level data storage operations such as reading, writing, and deleting raw license data. Accepts either a Swift implementation conforming to `BaseStorage` or an Objective-C object conforming to `LSBaseStorage`. If `nil`, the default internal file-based storage is used. This parameter is primarily intended for advanced customization of how license files are persisted.

- `currentLicense`

  Activated License or nil if no license is active.

  #### Declaration

  Swift

      @objc
      var currentLicense: License? { get }

- `baseStorage`

  Base Storage object passed by the user for custom license storage implementation

  #### Declaration

  Swift

      let baseStorage: any BaseStorage

- `register(userID:)`

  Register client with given id.

  Send register license request to the Floating server.

  Throws

  `LSError` if registration fails.

  #### Declaration

  Swift

      @objc
      func register(userID: String) throws -> License

  #### Parameters

  `userID` | User or instance id for license registration, it can be anything - email, host or domain name, handle, etc.

  #### Return Value

  Shared pointer to License if registration succeeded, throws exceptions in case of errors.

- `unregister(userID:)`

  Unregister client with given id.

  Throws

  `LSError` if unregistration fails.

  #### Declaration

  Swift

      @objc
      func unregister(userID: String) throws

  Typically should be called after license deactivation in the app uninstaller.

  Throws

  Error if clearing fails.

  #### Declaration

  Swift

      @objc
      func clearLocalStorage() throws

- `checkConnection()`

  Helper method to check connection to the Floating server.

  #### Declaration

  Swift

      @objc
      func checkConnection() -> Bool

  #### Return Value

  `true` if SDK is able to connect to the Floating server and `false` otherwise.

- `authenticateUser(user:password:)`

  Authenticates a user on Floating Server V2 and caches the JWT token.

  Use this before performing any other Floating Server V2 operations. This method only works with Floating Server V2 and will throw if used against a non-V2 server.

  Throws

  `LSError` if input is invalid or authentication fails.

  #### Declaration

- `register(userID:licenseId:)`

  Registers a floating license on Floating Server V2.

  The server assigns the client a floating session associated with a specific license ID and optional user (client) ID.

  Throws

  `LSError` if the input is invalid or registration fails.

  #### Declaration

  Swift

      func register(userID: String? = nil, licenseId: LicenseIDObjc) throws -> License

  #### Parameters

  `userID` | A client ID to associate with the floating license. If omitted, falls back to `currentLicense.floatingClientId`.
  `licenseId` | The license to register for Floating Server V2.

  #### Return Value

  The updated `License` object returned by the server.

- `getLicenseInfo(licenseId:)`

  Retrieves floating license information from Floating Server V2.

  Throws

  #### Declaration

  Swift

      @objc
      func getAllLicenses() throws -> [LicenseIDObjc]

  #### Return Value

  An array of active `LicenseIDObjc` values available to the user.

- `borrow(userID:licenseId:until:)`
