I'm trying to enable my app to receive a notification each time the event store changes.The documentation for EKEventStore at https://developer.apple.com/reference/eventkit/ekeventstore shows the following:static let EKEventStoreChanged: NSNotification.NameWhat does that mean? How do I use that information?

I used the Date class such as "currentTime = Date()", but I get a date that is off by 5 hours exactly. How do I get the current time? Is there a time zone setting I have to set?

sort array of dictionaries
How do I sort an array of dictionary objects based on the value of the dictionary? I understand I should use the sorted method of the array, but I don't understand the notation that uses $0.1 and $0.0. Where is the documentation on that?

app logging
Does Cocoa Touch provide a convenient way for apps to perform logging? Perhaps something similar to the print() command except it is kept after the app is installed?

Why are table view cells not showing in table view?
I am using more than one table view cell class on a table view. I have registered the reuse identifiers and the xibs. For some reason the cells are not showing. What should I check. I'm stumped.Here is my code:import UIKit class DetailTableViewController: UITableViewController { let items = [0, 1] override func viewDidLoad() { super.viewDidLoad() tableView.register(DueDateSwitchTableViewCell.self, forCellReuseIdentifier: "DueDateSwitchTableViewCell") let xibDueDateSwitchTableViewCell = UINib(nibName: "DueDateSwitchTableViewCell", bundle: Bundle.main) tableView.register(xibDueDateSwitchTableViewCell, forCellReuseIdentifier: "DueDateSwitchTableViewCell") tableView.register(DueDatePickerTableViewCell.self, forCellReuseIdentifier: "DueDatePickerTableViewCell") let xibDueDatePickerTableViewCell = UINib(nibName: "DueDatePickerTableViewCell", bundle: Bundle.main) tableView.register(xibDueDatePickerTableViewCell, forCellReuseIdentifier: "DueDatePickerTableViewCell") } override func numberOfSections(in tableView: UITableView) -> Int { return 1 } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return items.count } override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { print("tableView(_:cellForRowAt:)", "indexPath.row=", indexPath.row) let cell = UITableViewCell() switch indexPath.row { case 0: print("\tcase 0") let cell = tableView.dequeueReusableCell(withIdentifier: "DueDateSwitchTableViewCell", for: indexPath) as! DueDateSwitchTableViewCell cell.backgroundColor = UIColor.yellow case 1: print("\tcase 1") let cell = tableView.dequeueReusableCell(withIdentifier: "DueDatePickerTableViewCell", for: indexPath) as! DueDatePickerTableViewCell cell.datePicker.date = Date() default: break } return cell } }The cells show the numbers when I use this code in tableView(_:cellForRowAt:) before the line that says "return cell": cell.textLabel!.text = String(items[indexPath.section].hashValue)

version number
I am preparing to submit an app for the very first time.Why is the default version number 1.0? Doesn't that 0 get truncated? Would it be better if I changed the version number to 1? Would it make a difference?

build number
What are guidelines for numbering the build number? Should it just start with 0 and increment by one each time I archive a project for distribution?
