# MobileDocumentReaderSession The object you use to start reading a mobile document. ``` final class MobileDocumentReaderSession ``` ## Overview Use a `MobileDocumentReaderSession` object to read mobile documents from a properly configured device. Don’t create this object directly. Instead, obtain one by calling the [`prepare(using:)`](/documentation/ProximityReader/MobileDocumentReader/prepare(using:)) method of your [`MobileDocumentReader`](/documentation/ProximityReader/MobileDocumentReader) object. This returns a session after the successful configuration of the device. Maintain a strong reference to a session object for the duration of the document-reading process. You may use the same session object to perform multiple read operations, but you may perform only one read operation at a time from the device. ## Topics ### Performing a document request [`func requestDocument(Request) async throws -> Request.Response`](/documentation/ProximityReader/MobileDocumentReaderSession/requestDocument(_:)) Presents a sheet to read a mobile document and returns the relevant response. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
