Initializer

init(documentTypes:in:)

Initializes and returns a document picker that can import or open the given file types.

Declaration

init(documentTypes allowedUTIs: [String], in mode: UIDocumentPickerMode)

Parameters

allowedUTIs

An array of uniform type identifiers (UTIs). UTIs are strings that uniquely identify a file’s type. For more information, see Uniform Type Identifiers Overview.

mode

The type of file-transfer operation that the document picker performs. This argument accepts only the UIDocumentPickerMode.import or UIDocumentPickerMode.open mode.

Return Value

Returns an initialized UIDocumentPickerViewController object, or nil if the object could not be successfully initialized.

Discussion

In iOS 10 and earlier, this method returns the document picker view controller from the most recently used Document Provider extension. If no valid Document Provider can be found, it defaults back to iCloud Drive.

In iOS 11 and later, it returns the standard browser interface. This interface is the same one used by the UIDocumentBrowserViewController class.
