Which probably does a close which is not what you want. Assuming that your window controller is your window delegate (I think that is set up automagically) you want to add a method to your controller.

Before running your app open the Console app and put the process name of your app in the search bar. The run your app. I believe you'll see your output. It seems with the new log system is you have to

I don’t know if this has anything to do with your issue. One difference between a sandboxed and non-sandboxed app is that the “home directory” in a sandboxed app is inside the application container, n

I believe URL access requires com.apple.security.files.bookmarks.app-scope entitlement in a sandboxed app. Marc

This simple little playground doesn’t print any value for the last line. It is a minimization of an issue I’m having in a larger program where the key-value can not be found. Is it me (likely) or is i

Many, many thanks. One curiosity, though... that works in my application but I still get no output in the Playground sample code. Marc

Perhaps I’m expecting too much from Xcode. I’d quit and relaunched in order to get output for the code I’d posted. I didn’t expect I’d have to quit and relaunch again because I changed one line. Shoul

Has NSAlert changed recently? Looking at the documentation I see that the only initializer (swift) is `init(error: Error)` yet my code never passes an error. Is the Error argument new? But my issue is

Good thought, but I don’t think that is the problem this time. The alert is created in a function diretly called called from func tableView(_ tableView: NSTableView, acceptDrop info: NSDraggingInfo, r

I thought this was answered earlier. Implement this in your app delegate // MARK: Open File (UTI support) /// process files give to us via "Open With..." /// /// - parameter sender: unused /// - param

Can not be done accurately using only a Time Interval in seconds. You also need either the start or end date to figure out leap year complications. Don’t know of any. I’d probably roll my own. Marc

Ooops, I’m wrong... Leap year complications should be part of the time interval and be ignored. My programming history got the better of my knowledge... the first ever COBOL program I wrote figured ou

Are the lines terminated with a carriage return/line feed pair or are they terminated with the character string " ”. The results of step 2 and 3 are what I’d expect if the string contained the charact

Oh. Yeah. That’s too much work. var str = try String(contentsOf: urlContext.url) // (1) let lines = str.split(separator: “ ”) // (3) works and is faster in that you’ve removed an O(n) operation, I cre

NSImage can do the job.

NSImage opens lots of image file types: jpg, tiff, many raw formats, etc. Instead of thinking “tif” think “image file”.
