delete a json file in swift

To delete a JSON file in Swift, we can use the FileManager class provided by Apple.

Here's an example code snippet that shows how to delete a JSON file named "example.json" that is located in the documents directory of the app:

main.swift
// Get the path to the JSON file
let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let fileUrl = documentsDirectory.appendingPathComponent("example.json")

// Check if the file exists before trying to delete it
if FileManager.default.fileExists(atPath: fileUrl.path) {
    do {
        try FileManager.default.removeItem(at: fileUrl)
        print("File deleted successfully")
    } catch let error {
        print("Error deleting file: \(error.localizedDescription)")
    }
} else {
    print("File does not exist")
}

In this code snippet, we first get the URL to the app's documents directory using FileManager.default.urls(for:in:) and then append the name of the JSON file to it using appendingPathComponent(_:).

We then check if the file exists using FileManager.default.fileExists(atPath:), and if it does, we try to delete it using FileManager.default.removeItem(at:). If the deletion is successful, we print a message confirming that the file was deleted. If an error occurs during the deletion process, we print the error message to the console.

Note: Make sure to handle any errors that may occur during the file deletion process to prevent the app from crashing or behaving unexpectedly.
