@Quinn The Eskimo Once again I am in your debt! Yes I need to support multicast addresses and iOS13 as a minimum - so BSD Sockets it is! Fortunately I alreadu have a load of BSD stuff in the previous version of this app (Obj-C, Cocoa) which I will now try to port oevr to SwiftUI. Wish me luck as I google how to call C style code from SwitfUI..... Thanks again! .ps. I really don't like these new forums.. I guess Apple would prefer us to use Stackexchange.

@KMT Not helpful.

@Quinn Thanks again - I will look at your attachment and see if I can get my head round it. I truly wish I could target just iOS 14 - but I'm afraid I can't :-( You're right - I said SwiftUI, but I meant Swift... having done Objective-C for the past 15+ years, my old brain is finding it hard to migrate to Swift, but one must move with the times! I remember when we used to get Apple Developer tools shipped to us by UPS on CD's! My first apps were home-automation apps using Xcode and IB... now I'm doing some really cool stuff with Film and TV makers on movie sets using loads of UDP... whenever I post one of my silly questions I always hope I'll get an answer from Quinn The Eskimo! Thanks again. :-)

Here's an example how how a question would get completely missed - and the poor user gets no feedback... This was posted with the wrong tag: Oh - wait - I can't post an image or screen shot. Oh well. Never mind.

I got this working :-) But I wimped out :-( I just lifted my Obj-c code from the previous project, added the bridging header and viola! It just worked. So I guess that's OK - not 100% sure what the implications are (Is obj-c being deprecated? How long before I just have to figure out how to do all this in Swift?) I did try to get it working in Swift (Targetting iOS 13) but gave up - the time/gain balance was all wrong for now. Thanks @Quinn - your help is invaluable!

Hi Quinn - thanks for taking the time for me. I posted the bug - FB8699241 - regarding whitespace. I also tried a number of your suggestions, and find that it just feels cludgy and workround-y I think most really good developers have just abandoned the forums. In my post over on the swift forum [... well there is no "over on ... " in this new world, so in the big, massive pile of messages tagged with various random tags, and hopefully somewhere by adding lots of filters and gueswork I might be able to find my way back to my own message], I added a reply you your latest reply. The new reply that I made just appeared at a random place in all the other replies - which makes it utterly impossible to read the question, and the replies, in any logical order that makes sense to me. OK, OK - I hear you say "quote the thing your replying to" but it stillo forces the user to track and order these things in the head, rather than on the screen. I have one suggestion that will fix all the problems: Simply make "h.t.t.p.s://de.v.e.l.o.p.e.r.a.p.p.l.e...c.o.m./.f.o.r.u.m.s." point to w.ww.st.a.c.k.e.x.ch.a.n.g.e...c.o.m. and we're done!

To do this: Click your avatar in the top right. In the resulting popup, click anywhere in the top cell that’s outside of the Edit Profile link. And yeah, I agree that this is quite non-obvious. We have a bug tracking that (r. 66042728). Yeah - that doesn't work - maybe it's been 'fixed' You now have to click on your Avater and then click on your Avatar in the top cell.

@Quinn See - perfect example of how Tags don't work for forum structure!

So great you could join us! I'm here too. Having lots of fun.

First of all, I suggest you search for "Stanford CS193p" in YouTube. (We developers are not trusted enough by our fruity provider to post URLs into these forums, so you'll have to pretend it's 1991 and do it yourself.) That will give you an excellent list of real world lectures by an fantastic tutor on Swift and SwiftUI - absolutely the best place to start.

Don't you just love the fact that this thread is over two months old, has loads of irrelevant answers, and other people 'hijacking' it to ask unrelated questions about iPhones.... yet it still appears as the most relevant thread when you enter Apple's developer forums? Nice!

Yip, +1 here

Time for an emergency patch, Apple! One can hope

I strongly suggest you watch the first 3 vidoes in the series from Stanford University Search on Youtube for Stanford CS193p Those will give you a fantastic start to SwiftUI and the MVVM paradigm. Let us know hw you get on!

How old are you?
