I have a few basic questions developing an app to run on macOS using Xcode 11 interface builder.How do you change the background color of the window, toolbar color etc. It seems like this should be easy but I don't see any option in the attributes inspector about changing background color? Do you need code to modify this? If so, an example would be helpful.How do you set the window to remember size and position after quitting the app?How do you add a custom image to a toolbar item?Thanks

How to grant access to Users Documents folder from a sandbox Xcode 11 macOS app. I want the app to be able to open an existing file (without using NSOpenPanel) in the users document directory. I have looked through the apple sandbox doc and don't see a way to do this. How is this done?

I have the following function I am leaning from: func getAllCustomers() -> NSArray {     var rowsFetched: NSArray     do {         try dbQueue.read { db in             let custlist = try Customers.fetchAll(db)             rowsFetched = custlist             }          }     } catch {         print("\(error)")     }     return(rowsFetched) } The problem with this code is in the assignment "rowsFetched = custlist" I get the following error: Cannot assign value of type 'Customers' to type 'NSArary However, type 'Customers' is really an array. How do I fix this?

Using Xcode 11 for a macOS app and storyboards I created an app with three window controllers/view controllers. When first testing the second and third window would open in Tab of the first window, but along the way I changed something on one of the secondary windows and now that window opens in its own window. (Did not notice exactly when a change or changes caused this to happen) I have a buttons in the main window tool bar that when clicked it provides a segue to the second and third window. Also, I have tabbing mode on all three set to automatic and I have tried preferred with all windows but the second window still opens in its own window. I realize this does not contain much detail, but I was hoping someone had seen this before and could help. How can I get this window to open as a tab as it originally did? I have looked at tab view to maybe redo them but this is not exactly what I was looking to do. Thanks

I am using Xcode 11.6 and IB for a macOS app and using a tableview. It has 10 columns. I would like to add the functionality to right click on the header and have a pop menu with the column names to select which columns for the tableview to show/hide. What is the best approach to add this functionality? How is this done?

Is there a way to add an image to a post on the Forum?

Anybody else having problems with app icon on Xcode 12 not showing up for a macOS app?

I would like to create a popup menu using swift coding in a macOS app from a right click event using Xcode 11 or 12. Can't seem to find an example of this. I see plenty of IOS examples but none for macOS. Does anyone have an example of this you could share or could show me how this is done. Also, I know how to add a menu to to the View Controller but this allows right click from anywhere in the tableView and I want the popup menu to show when you right click on a row in the table. If anybody is familiar with quicken for Mac I want the same function as it as when you right click on a row in an account register. Here is the code for the right click event:   // right click action     override func rightMouseDown(with theEvent: NSEvent) {     let point = tableView.convert(theEvent.locationInWindow, from: nil)         let row = tableView.row(at: point)         selectedCustomer = custviewModel.customers[row].custNumber!         print(selectedCustomer)         // Add popup menu         print("right click")         print(row)     } I have ask this question on couple of other forums as well as searched for tutorials on this and have come up empty.

I am using Xcode 11 for a macOS app. When I add a text field(s) to a window and then test, the text field shows up. However when I selected the text field(s) and use the "embed in" button for a stack view they no longer show up. I have even tried this on a test project with one label and one text field and the same thing happens. I must be missing something? Why does this occur?
