I have an NSViewController which contains a button. This button is hooked up to another NSViewController in the storyboard so that when the button is pressed, the secondViewController is shown as a Sheet overlay. This works great and I get the look that I want, but a problem occurs when I subclass NSViewController and assign this subclass to the SECOND NSViewController. The first one works fine whether it has a custom class or not. If i do indeed assign a custom class to the second one, i leave the class exactly how it is created as shown below, but when I press the button, I get no error code (other than the annoying LLBD print in the console) and the app crashes. If someone could advise as to what I am doing incorrectly, or perhaps a way to get a better error log so i can troubleshoot a bit better, that would be appreciated. Please ask for more information / screenshots. Answers in both Swift and objective-c are fine.
import Cocoa
class CustomVC: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do view setup here.
}
}
The below code is for my initial view controller. It contains 3 sets of data to fill the tableView depending on which segment of a NSSegmentedContoller is pressed. The sheet is going to be used to add a new item to the array - it will pop over the screen so that I can enter new details before saving them into one of the arrays. Hopefully this makes sense.
