find the last accessed date of a json file in swift

To find the last accessed date of a JSON file in Swift, you can use the FileManager class to get the attributes of the file, and then extract the desired information. Here's some sample code:

main.swift
let fileManager = FileManager.default
let filePath = "path/to/your/file.json"

do {
    let attributes = try fileManager.attributesOfItem(atPath: filePath)
    let accessDate = attributes[.modificationDate] as? Date
    print("Last accessed date: \(accessDate)")
} catch {
    print("Error: \(error.localizedDescription)")
}

In this code, we first get an instance of the FileManager class, which we'll use to access the file. We then define the file path of our JSON file.

Next, we use a do-catch block to try to get the file attributes using the attributesOfItem(atPath:) method of the FileManager class. This method throws an error if the file cannot be accessed, so we need to wrap it in a do-catch block.

Once we have the file attributes, we extract the modification date using the .modificationDate key, and cast the value to Date.

Finally, we print out the last accessed date of the JSON file.
