Where : you have to know what to track and search on line to get this information. How: Look and copy or just write scripts to collect automatically. But trading requires very rapid information, you will lag behind. But may be you have some innovative idea to make your app and service attractive (not to be discussed here of course)…

I cannot reproduce, or I don't understand what you do. When I turn on "Mac" in General settings or Target, I have an alert that warns me of the change. But I can turn it off by unchecking the Mac checkbox. Where do you set Catalyst exactly ?

Could you show the code where it occurs ?

What is your set up: a navigation controller linked to a first VC with a RELATIONSHIP segue : this first VC is the first of stack a second VC linked to a third VC with a segue (show segue for instance) : it is second on stack Then the back button should appear in this 3rd VC, not on the second (because it is the first of stack, so nowhere back to go). So, if you have a single controller in the navigation stack (the first VC), there is no back button. In my case its not visible but when I click in that place it's working. What is working ? What do you get when you click there ? Could you confirm or explain what is different ?

some counters (number of posts) never change (at least for me since 5 months) I just noticed a few improvements on the forum: the counter of total posts by a developer (tested on my profile) now updates. Maybe more improvements to expect in the near future ?

would like feedback fast during the process. I prefer chat above forum.  Sure, everyone would like. You have 2 options: rely on the help of other developers (this forum, S.O where you can have chat conversations) Did you ever post a technical question on the forum (seems not) ? You should and you will see what type of help you can get. but remember, developers on those forum are doing for helping, and are not at your service on request. And the code of conduite on those forum is that you not only ask for help, you also provide help to others if you can. go to a paying expert support. Then you will get the type of service you pay for… Good luck and don't forget to close the thread when you're done.

You marked your answer as correct. That probably means you have solved the problem. have a good continuation.

how can one see the threads he contributed to ? Seems we can only filter the one we authored. That's now possible. Going to your personal page, there are new links to Questions, Replies, Watching. A BIG improvement.

That's the output of your app. Please show the code that produce this output.

Why does your stepper have a zero frame ? And stackView no frame defined ?

this code was suggested in another post … Does this affect how the stepper alters values in the model? That should not affect directly, but could be the stepper does not receive the message ? With the limited code we had, we could just guess. We probably have all the code now, but in a lot of small pieces. Do you expect us to reassemble (I will not) or are you going to publish something more directly usable ? In any case, it is always risky to paste code without really understanding what it is doing.

These view controllers are not directly connected by segues. Could you explain the sequence between StoreViewController and LiveViewController ? How do you transition to StoreViewController ? Normally, you should set the delegate in destination in the initiating controller.

This cannot work: override func viewWillDisappear(_ animated: Bool) { } super.viewWillDisappear(animated) self.navigationController?.isNavigationBarHidden = false } } Closing curly bracket line 5 is an extra. So, did you copy the REAL code ? That's absolutely needed.

Is there a limit to the speed at which information can be printed in a label on the iPhone screen? What do you mean ? this rate is restricted until a developer joins the Apple Developers' Group What link do you make with the speed of print to a label ?

You marked you thread as solved. So that means you have the answer. Don't expect many people to look at it and provide help.
