So I need to do my own callback timer, got it. Thanks @MobileTen

That code appears to read the stream live, still too new at this. Going to have to study it to find out how to read from saved file.

Sorry, this does not make my app wait. Someone suggested I put the call to the rest of my app as a function in the completion part of AVCaptureDevice.requestAccess. I guess that makes sense. I would have though there was a way to: 1 - create a separate thread/queue 2- Make a call to the thread 3 - Tell calling app to wait till the new thread/queue is done

See code below please

So if I read you correctly? Do whichever I please, there is no difference as far as operations are concerned?

So take make sure I read it correctly, Sets and Array are the same except a Set has no ordering, and each value must be unique? And in the example I gave, Calendar.Component was already defined as a set?

Did most of my work in Windows, that had such a feature, so am looking for an equivalent. But also, there might be a case of searching through multiple instances to find a particular one maybe?

Wow! The ‘f’! I kept looking at the ‘x’! Thank you. I seriously think I have a reading disorder sometimes.— SergioDCQ less than a minute ago

Oh you.....I see what you did there. I'm going to start calling what you did "Passive/Aggressive teaching." And I mean that as a compliment. Thank you. — SergioDCQ 40 minutes ago Edit this post  Report post of SergioDCQ

Oh no, I got it as soon as I read the line you made me throw in...perfect teaching method. Was just posting the answer over at StackOverflow, was going to do it here next, but you beat me to it. Thank you again.

I currently have it as below, so that the completionHandler gets called first and no matter what ` func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive response: URLResponse, completionHandler: (URLSession.ResponseDisposition) -> Void) { completionHandler(URLSession.ResponseDisposition.allow) if let httpResponse = response as? HTTPURLResponse { xFile?.httpResponse = httpResponse.statusCode DispatchQueue.main.async { [self] in if httpResponse.statusCode != 200 { ...my code } } } }`

I have to clean them up, because at first I was using the wrong delegate. However, I do need to eventually add download as well. So will have to see which I need and don't at some point

I find the way Swift handles certain things (i.e. the OP) a little too drawn out. Therefore I doubly appreciate this excellent, well explained answer.

It was just a simple oversight, because I was trying it out quickly. It’s now in there and cell is no longer an optional.
