JSON: Renaming and Deleting Members

See more JSON Examples

Demonstrates renaming and deleting members. This example uses the following JSON document:

{
   "apple": "red",
   "lime": "green",
   "banana": "yellow",
   "broccoli": "green",
   "strawberry": "red"
}

Swift

func chilkatTest() {
    var success: Bool = false

    let json = CkoJsonObject()!

    success = json.load(json: "{\"apple\": \"red\",\"lime\": \"green\",\"banana\": \"yellow\",\"broccoli\": \"green\",\"strawberry\": \"red\"}")
    if success != true {
        print("\(json.lastErrorText!)")
        return
    }

    // Rename "lime" to "lemon".
    success = json.rename(oldName: "lime", newName: "lemon")
    // Change the color to yellow:
    success = json.setString(of: "lemon", value: "yellow")

    // Rename by index.  Banana is at index 2 (apple is at index 0)
    success = json.rename(at: 2, name: "bartlett_pear")

    // Delete broccoli by name
    success = json.delete(name: "broccoli")

    // Delete apple by index.  Apple is at index 0.
    success = json.delete(at: 0)

    json.emitCompact = false
    print("\(json.emit()!)")
