I already filed a ticket before this posting. https://feedbackassistant.apple.com/feedback/13633103 But I am not sure if it's publicly viewable.

Great news for me and other individual developers! Broadcom acquired VMware.com and now VMware Workstation Pro/Fusion Pro are free for personal use.

Yeah... I found it myself after 15 minutes of digging. It's right there under the "Assistant" menu item.

It's strange. When I tried again, I found the file in /tmp: - (void)test { NSError* error; [@"abc123" writeToFile:@"/tmp/testfile" atomically:NO encoding:NSUTF8StringEncoding error:&error]; if (error) NSLog(@"%@", error); }

Finally I have to re-invent the wheel to solve this mysterious memory leak which I cannot control without the wheel. I am not sure if it is too bold to declare that NSData has serious problems with memory footprint, but... After I devised my own memory management facility (a smart buffer class), the memory footprint drops drastically and stops growing continuously. This is observed for several days.

I also have the same question here.

Again, I found it myself. override func windowDidLoad() { super.windowDidLoad() window?.level = .floating }

I did much search on the web and found no answer. The only clue to my question is that I have use another "template" tableview that is identical to the inner tableview. Finally I devised a working solution, I posted here for the purpose of helping others who may have the same/similar problem. Note there is a little trick about calculating the actually row height - you have to include height of the template tableview's header view. func tableView(_ tableView: NSTableView, heightOfRow row: Int) -> CGFloat { if tableView is DetailsTableView { return tableView.rowHeight } if let rowHeight = rowHeights[row] { return rowHeight } let item = categorizedItems[row] if sizingTableView == nil { var objects: NSArray! detailsNib!.instantiate(withOwner: nil, topLevelObjects: &objects) for object in objects { if let sizingCellView = object as? DetailsCellView { sizingTableView = sizingCellView.tableView sizingTableView.delegate = self sizingTableView.dataSource = self sizingTableView.isHidden = true sizingTableView.enclosingScrollView?.setFrameSize(NSSize.zero) self.view.addSubview(sizingTableView) break } } } print("<", sizingTableView.bounds.height) sizingTableView.row = row sizingTableView.files = item.files sizingTableView.reloadData() print(">", sizingTableView.bounds.height) var rowHeight = sizingTableView.bounds.height + (sizingTableView.headerView?.bounds.height ?? 0.0) + summaryTableView.intercellSpacing.height rowHeights[row] = rowHeight if rowHeight > MaxRowHeight { let trailingHeight = (sizingTableView.bounds.height / Double(item.files.count)) * Double(TrailingRowCount) if rowHeight - MaxRowHeight < trailingHeight { // Try reserve height for some rows to let scrollbar look more natural. rowHeight = max(0, MaxRowHeight - trailingHeight) } else { rowHeight = MaxRowHeight } } return max(rowHeight, summaryTableView.rowHeight) }

I found a solution myself, after days of researching and experiments. It's related to another question "How tell if NSTableView is already displaying its last row entirely?". // For the inner tableview's scrollview class MyScrollView: NSScrollView { var onScrollWheel: EventHandler! override func scrollWheel(with event: NSEvent) { super.scrollWheel(with: event) // In onScrollWheel, determine if vertical scrollbar is hidden or at top/bottom, // then delegate this event to the outer tableview: // outerTableView.scrollWheel(with: event) onScrollWheel?(event) } }

At last, I found the answer myself, again. The answer lies in NSScroller.floatValue which inherited from NSControl. let shouldDelegate = { if let scroller = scrollView.verticalScroller { return scroller.isHidden || scroller.floatValue == 0 || scroller.floatValue == 1.0 } return true }()

Maybe my question is too general. I have a need to calculate all width of an NSTableView. However, I found that total width of all columns is far less than NSTableView.bound.width: let width = tableView.tableColumns.reduce(0) { ac, col in ac + col.width } print(width, tableView.bounds.width) This is true even I manually adjust last column so that it fills the gap between the column and tableview right border. -----------| <- table right border last column| -----------| So I assume NSTableColumn.width and NSView.bounds.width are using different units.

Ah, I found out why, though it's a little embarrassing... After so many years, I realized that NSApp.mainWindow is dynamic - it can be any window that has the key focus! I have to create a global variable to keep instance of the initial window (as designed in main storyboard). var mainWindow: NSWindow? // Set in MainWC.windowDidLoad class AnotherWC: NSWindowController, NSWindowDelegate { override func windowDidLoad() { super.windowDidLoad() print(self.className, #function) } func windowShouldClose(_ sender: NSWindow) -> Bool { print(self.className, #function) return true } func windowWillClose(_ notification: Notification) { print(self.className, #function) print(mainWindow ?? "mainWindow is nil") mainWindow?.orderFront(nil) } }

Please ignore my question. It should be always like this because I set "Host Application" to None in the unit test target.

I have found where the Web entry is. I have to enable CloudKit service in project settings. Now I have another problem - I accidentally created several database containers (long time ago out of curiosity by clicking a button that says "Enable ClouldKit" or something similar). But I cannot find a way to delete the garbage items. The only way is to hide them in the CloudKit management Web UI.

Anyway, I found out the cause. The error is thrown when initializing XMLDocument with an empty string: let xd = try XMLDocument(xmlString: "")
