Back to back challenges, phew! Don’t worry, as you saw in the previous video it’s really simple to migrate from using JSON to using PLists.

private func loadPListPrioritizedTasks() {
  ...
}

do {
  let tasksData = try Data(contentsOf: tasksPListURL)
  prioritizedTasks = try decoder.decode([PrioritizedTasks].self, from: tasksData)
} catch let error {
  print(error)
}

let decoder = PropertyListDecoder()

loadPListPrioritizedTasks()

guard FileManager.default.fileExists(atPath: tasksPListURL.path) else {
  return
}
