Answer 1

I have found some helpful tutorials and able to search string in the outlineView.

    let userInput  = txtSearchField.stringValue
    guard let outlineView = myOutlineView else { return }

    var itemIndex: Int = outlineView.row(forItem: userInput)
    let value = outlineView.item(atRow: itemIndex)
    
    if itemIndex < 0 {
        //if item is not available in the outlineView
        
    }
    print("Expanding row", itemIndex)
    outlineView.selectRowIndexes(IndexSet(integer: itemIndex), byExtendingSelection: .init(true))
    outlineView.scrollRowToVisible(itemIndex)
