Hello:
I am adding a video file to my MAC application. Before I create an archive, the video plays perfectly but when I run a copy of the archive, when I click on the button to start the video, NOTHING HAPPENS. No error message, Nothing. Any help to resolve this issue will be appreciated. Here is the code:
This code:
@IBAction func AVSegue(_ sender: Any) {
let mainStoryboard = NSStoryboard(name: "Main", bundle: Bundle.main)
guard let avPlayerViewController = mainStoryboard.instantiateController (withIdentifier: "AVID") as?
AVPlayerViewController else {
print("Couldn't find viewController" )
return
}
presentAsModalWindow(avPlayerViewController)
}
triggers the ViewController with the AV Player:
import Cocoa
import AVKit
import AVFoundation
class AVPlayerViewController: NSViewController {
@IBOutlet weak var playerView: AVPlayerView!
override func viewDidLoad() { super.viewDidLoad()
let url = URL(fileURLWithPath: Bundle.main.path(forResource:"SMRIntro",ofType: "mp4")!)
let player = AVPlayer(url: url)
playerView.player = player
player.play()
}
}

My Mac OS app was running fine until today when my TabView Controller ceased to load images for the pop-up (xy) button to display.
When I checked the connection there was this error message:
Container View does not have a IBSegueTriggerViewDidLoad binding.
Below the Triggered Segues is ViewDidLoad and Below the Connection tab is Tab View Controller: Embed with the yellow caution icon. By hovering over the icon I see the above error.
What can I do to reconnect this binding? I deleted the connection and redo the segue but the error comes back.
Any help will be appreciated.

Hello:I've read just about every thing I could find about animations in my MAC OSx app. However, I've not been able to find a useful tutorial of example. Nearly All the examples i found are for iOS and all of those animations are initiated by tapping a button.I want to be able to make the image on my main window Zoom in from a small icon to fill the window in a gradual zoom in motion as the app main View is loaded.I will appreciate any example, tutorial, or Swift resource that could be useful in solving this problem.Thanks in Advance.

I want to some how to mark each fetched record so I can know whether or not it has been called before.I don't want to save every fetched record to a data store then compare new fetches with what is there because it would call for a lot of processing resources.Is there an easier way?Thanks.
