Swift:
Створення тимчасового файлу
How to: (Як зробити:)
Swift has the FileManager
class to help out. Here’s a quick example:
import Foundation
func createTemporaryFile() {
let tempDirectoryURL = FileManager.default.temporaryDirectory
let tempFileURL = tempDirectoryURL.appendingPathComponent("tmpfile").appendingPathExtension("txt")
let content = "Temporary data here"
do {
try content.write(to: tempFileURL, atomically: true, encoding: .utf8)
print("Temporary file created at \(tempFileURL.path)")
} catch {
print(error)
}
}
createTemporaryFile()
Sample output:
Temporary file created at /var/folders/.../tmpfile.txt
Deep Dive (Поглиблений Розгляд):
Historically, temporary files date back to the early days of computing, used to manage limited storage space and reduce memory usage. Alternatives to temporary files include in-memory storage or databases, but these may be volatile or impractical for large data sets. In Swift, FileManager
ensures that temp files go in the correct directory, which is unique per user and session, minimizing security risks and avoiding clashes.
