.Declaration
Swift
public struct Options : OptionSet, Sendable
-
A closure executed once a
DownloadRequest
has successfully completed in order to determine where to move the temporary file written to during the download process. The closure takes two arguments: the temporary file URL and theHTTPURLResponse
, and returns two values: the file URL where the temporary file should be moved and the options defining how the file should be moved.Note
Downloads from a localfile://
URL
s do not use theDestination
closure, as those downloads do not return anHTTPURLResponse
. Instead the file is merely moved within the temporary directory.Declaration
Swift
public typealias Destination = @Sendable (_ temporaryURL: URL, _ response: HTTPURLResponse) -> (destinationURL: URL, options: Options)
-
Creates a download file destination closure which uses the default file manager to move the temporary file to a file URL in the first available directory with the specified search path directory and search path domain mask.
Declaration
Swift
public class func suggestedDownloadDestination(for directory: FileManager.SearchPathDirectory = .documentDirectory, in domain: FileManager.SearchPathDomainMask = .userDomainMask, options: Options = []) -> Destination
Parameters
directory
The search path directory.
.documentDirectory
by default.domain
The search path domain mask.
.userDomainMask
