What is going on?
Known (by Apple) bug. My report was closed as a duplicate of 30350792. My workaround is to do this in my do block after attempting to copy a file to saveFileUrl: try fileManager.copyItem(at: url, to: saveFileUrl) /// DANGER WILL ROBINSON -- the above call can fail to return an /// error when the file is not copied. radar filed and /// closed as a DUPLICATE OF 30350792 which is still open. /// As a result I must verify that the copied file exists if !fileManager.fileExists(atPath: (saveFileUrl.path)) { unexpected(error: nil, "Cannot copy \(url.path) to \(saveFileUrl.path)") return false } which duplicates what the catch block would do.
