looking back I went with //! Connect the Output Pipes [aTask setStandardOutput:[NSPipe pipe]]; [aTask setStandardError:[aTask standardOutput]]; //! Tell the Pipe to notify to read in the

Ah, that worked a treat!!! Thanks so much Sandor. —Graham

Hi Chris, actually I think I am doing that. it’s a while since i put this code together, and exactly what the arguments are is not so clear now. I set the NSTask.standardOutput to an NSPipe, and I

Sure, just use NSTask’s own standardInput, standardOutput, and standardError support with NSPipe. No need to tell the task to send its stdout to some intermediate file that your app then opens and

Hi all, In my app I use NSTask to launch a copy of ffmpeg as a child process to do some work in the background on a video stream. I pass parameters to this task via the command line arguments

I have some utility classes with class methods in Objective-C and a copy in Swift. For now, I am using the Swift version, but calling one of the methods from a class that is Objective-C. While I

By my analysis the capture list in the DispatchQueue closure is unnecessary, because by that point `self` is already weak. You can prove this by adding a `weak var this = self` and change the `self`s

I am doing some processing of network requests, and the response is processed in a background thread using a closure. The closure executes some logic on the background thread and then (possibly)

Jens, Thanks for the info on the enumeratorAtURL: method. I take back my suggestion regarding the bug then. Regarding my pseudo-security remarks: yes, I agree of course that some of the measures make

Ok it was my first post and it took 2 days for it to arrive... By now the issue is solved: I had to reset the Command Line Tools path with xcode-select -r

The OP was calling -[NSFileManager enumeratorAtPath:], which is an old API that predates NSError, so failing silently is all it can do. (Cocoa APIs do not throw exceptions except in the case of

I read this discussion with interest... that's good to know! May I also suggest to submit it as a bug to Apple. That is, if a function fails because of sandboxing then it shouldn't just fail silently.
