withFile(contentType:allowOpenInPlace:fileHandler:)

Declaration

func withFile<Result>(contentType: UTType, allowOpenInPlace: Bool = false, fileHandler: @escaping (URL, Bool) async throws -> Result) async throws -> Result

Parameters

• contentType:

  A content type of the returned data.

• allowOpenInPlace:

  Whether the file should be opened in place, if possible.

• fileHandler:

  A closure that accepts the file URL as a parameter. The file is written to a temporary destination and removed right after the closure returns.

Discussion

If the file is not opened in place, the system removes it after the fileHandler closure returns.
