My mistake, just change:     if let cell = tableView.cellForRow(at: IndexPath) {

Maybe sourceRect of zero size causes the problem:    let popoverPresentationController = tableViewController.setUpPopoverPresentation( sourceView: borderLabel, sourceRect: CGRect(x: anchorX, y: anchorY, width: 0, height: 0)) Try and give non null width and height.

Write an init() where you will set the value. Get more details in this other thread: https://developer.apple.com/forums/thread/685605

TF ???

Just a typo, working in forum editor and not XCode: it is indexPath and not IndexPath     if let cell = tableView.cellForRow(at: indexPath) {

I don't know enough about cell. Is it a custom class ? Or is yahooName the title of the standard cell ? In such a case, just call: selectedNameInCell = cell.textLabel!.text!

So you should:     if let cell = tableView.cellForRow(at: IndexPath) as? FavCell {       selectedNameInCell = cell.name.text     }

To be sure to understand where you stand now, could you repost the most recent code: IBAction prepare for segue Another option is to get the name directly in the IBAction: @IBAction func CamButtonA(_ sender: UIButton) { // Find the cell which contains this button var superview = sender.superview while let view = superview, !(view is UITableViewCell) { superview = view.superview } guard let cell = superview as? FavCell else { return } selectedNameInCell = cell.name.text performSegue(withIdentifier: "hs", sender: nil) }

Did you search for "Swift sockets" ? There are a lot of references and tutorials: https://stackoverflow.com/questions/28466665/sockets-with-swift and notably this one: h t t p s : / /stackoverflow.com/questions/28466665/sockets-with-swift

Which version of Xcode / MacOS ? I tested with Xcode 13ß4 and MacOS 11.5. I get 1 as a result (called from viewWillAppear). Could you post the code so that we can try to replicate ?

hide all buttons in NSAlert Which buttons ? There are only the buttons you define yourself, so why do you add if you want to hide? But how do you expect user to close the alert ?

That seems to be an old issue with keyboard size. I filed a bug, in 2018 (radar ID 38117524 - FB5721145) for keyboard size issues. Here's an abstract: Value for keyboard height returned by note.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue is erroneous after turning iPad from Portrait to Landscape This is for a numeric keypad on iPad (numbers at top, special characters below, help line at the top). This occurs both on device and in Xcode simulator Steps to Reproduce: On iPad, select numeric keypad (numbers at top, special characters below, help line at the top), for a textField In keyboardWillShow, get the keyboard size, and ask for printing it : @objc func keyboardWillShow(_ note : Notification) -> Void { if let keyboardSize = (note.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue { print("keyboardSize", keyboardSize) Start in landscape, click on field to show keyboard, then turn portrait then return landscape, the keyboard staying displayed on screen. Expected Results: Height should be 398 when returning to landscape Actual Results: Height is 142 after returning to landscape. keyboardSize (0.0, 768.0, 1024.0, 398.0) // Landscape, seems correct keyboardSize (0.0, 1024.0, 768.0, 313.0) // Portrait, effectively smaller in height keyboardSize (0.0, 768.0, 1024.0, 142.0) // Return to landscape: height is now clearly wrong keyboardSize (0.0, 626.0, 1024.0, 142.0) // Note: keyboardWillShow is called a second time and removes 142.0 from origin.y. Version/Build: IOS 11.2.5 (15D100) Xcode Version 9.2 beta (9C34b) OSX Version 10.13.3 (17D102)

If that occurs always at 60 seconds, not at the same file position (if you can check), that looks more like a time out. Did you try with a smaller file that would need just less than 60 s ?

Have you checked you have enough disk space ?

it doesn't work That tells nothing, please explain what you get (or don't get) and what you expected. Are model.dateSaved and dateFromFirstViewboth Date ? If so, are the dates exactly the same ? You should add some print to log: if model.dateSaved == dateFromFirstView { print("Dates are the same") cell.textLabel!.text = model.event } else { print(model.dateSaved, "is not the same as", dateFromFirstView) } And tell what you get.
