I solved the problem, in reshape I changed glOrtho() to glfrustum(). I'm happy.

I replaced the NSArrayController from the object library and renamed the @property(strong)IBOutlet NSArrayController * vrArrayController; Now runs awakeFromNib only one time and the controller is nil.

No Reply is a Reply too. ☹️

Hi Claude, it is Swift code, this project shall be the twin of my objective-c what must close because of deprecation of OpenGL. The first what I want is getting access to managedObjects, I send you the AppDelegate : import Cocoa import CoreData @main class AppDelegate: NSObject, NSApplicationDelegate { @IBOutlet weak var arrayController: NSArrayController! @IBOutlet weak var tableView: NSTableView! @objc var currentManagedObject: [NSManagedObject]; // error: func myPrint() { if(arrayController != nil){ print(arrayController!) }else { print("arrayController is NIL") } if(tableView != nil){ print(tableView!) }else { print("tableView is NIL") } } var center = [NotificationCenter.default] [center.addObserver: self, selector:#selector(rowSelectionDidChange(_:)), name:Notification.Name( selectionDidChangeNotification), object:nil] // error: Expected declaration @objc func rowSelectionDidChange(_ notification: Notification){ if(arrayController != nil){ var selected:[] as Any var arranged:[] as Any // error : /* Consecutive statements on a line must be separated by ';' Insert ';' Expected element type Insert ' <#type#>' Expected expression */ selected: NSArray = [arrayController.selectedObjects]; arranged = [arrayController.arrangedObjects]; if((selected.count) >= 0){ // ... } } } func applicationDidFinishLaunching(_ aNotification: Notification) {} func applicationWillTerminate(_ aNotification: Notification) {} func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool { return true} } I hope it helps you to help me

I corrected the notification and got error : [center.addObserver: self, selector:#selector(rowSelectionDidChange(_:)), name:Notification.Name( selectionDidChangeNotification), object:nil] // error: Expected declaration rowSelectionDidChange(_:) do not belong to tableView, it is the function I want to use if(arrayController != nil){ var selected:[] as Any var arranged:[] as Any /* error : Consecutive statements on a line must be separated by ';' Insert ';' Expected element type Insert ' <#type#>' Expected expression */ selected: NSArray = [arrayController.selectedObjects]; arranged = [arrayController.arrangedObjects]; } } ` p.s. please give me a link of your communication rules .

No framework, the projects I mentioned arose on Xcode 4.2, maybe a difference .

Edit: selector: #selector: ( NSTableView.rowSelectionDidChange(_:)), name:"NSTableViewSelectionDidChangeNotification", object: nil)

My fault, the Reason is : Xcode 4 has the default "Automatically Run" and 14 has "Manually Run". Thank you for your reply.

Sorry, my mistake, I deleted the class, closed Xcode and began new, I got no error. Maybe the reason is that I use Sierra. In the near future I buy a new iMac, then I need your support again.

Edit: The two lines list is fine too.

Hi, I solved the problem with trial and error. The octahedron in the top sight gave me limits and I changed [0,0,-10] to [-0.25,-0.25,-10];

@OOPer I changed the project format to 9.3 and the Error disappeared. I changed back to 12.4 : No error. I know almost nothing about Metal and I hope the community help me when i stuck in the future. Uwe

Sorry, wrong button pressed.

Yesterday I found in Application Support/CallHistoryDB: Multiline CallHistory.storedata CallHistory.storedata-shm CallHistory.storedata-wal BlockQuote I moved the folder to an external device and killed the original. I setup a new project StoreData, killed the StoreData.xcdatamodeld and replaced it with the model of my project. This works, but before a must Sandbox uncheck.

Yesterday I found in Application Support tree documents : Multiline CallHistory.storedata CallHistory.storedata-shm CallHistory.storedata-wal BlockQuote I moved the docs to an external device and killed the originals, today they were at place again. I would setup a test app, but how do I make ad hoc a failure, so that CD trashes to have a reason to trash the store ?
