insert data into plist in swift

Here's how you can insert data into a plist file in Swift:

1. First, locate the path for your plist file. You can use the following code to get the path:

   main.swift
   guard let path = Bundle.main.path(forResource: "yourPlistFileName", ofType: "plist") else { return }
   101 chars
   2 lines

2. Load the content of your plist file into an NSMutableDictionary

   main.swift
   let plistData = NSDictionary(contentsOfFile: path)
   let mutablePlistData = plistData?.mutableCopy() as? NSMutableDictionary ?? NSMutableDictionary()
   148 chars
   3 lines

3. Insert data into the NSMutableDictionary

   main.swift
   mutablePlistData.setValue("Your value", forKey: "Your key")
   60 chars
   2 lines

4. Write the updated NSMutableDictionary contents back to your plist file

   main.swift
   mutablePlistData.write(toFile: path, atomically: true)
   55 chars
   2 lines

Here's the complete code:

main.swift
guard let path = Bundle.main.path(forResource: "yourPlistFileName", ofType: "plist") else { return }

let plistData = NSDictionary(contentsOfFile: path)
let mutablePlistData = plistData?.mutableCopy() as? NSMutableDictionary ?? NSMutableDictionary()

mutablePlistData.setValue("Your value", forKey: "Your key")

mutablePlistData.write(toFile: path, atomically: true)
