If you have found a way to execute one function - func1() -, it is easy to execute all: func executeAll() { func1() func2() // etc } and call executeAll() as you called func1().

Looks like you are considering a lot of app ideas. That's good, but you should not pick a topic just because you think it is a buzz topic. You should be clear on: what is the (unsolved) problem you want to solve ? Not just create a me-too app. Note: Questions in this forum must deal with specific developer's question, not a general question "how should I create an app to…" Good luck. And don't forget to close your threads when you're done.

What are you looking for ? Delivering your own certification ? Enroll them in a certification program ? If so, search for "SWIFT certification test" ; there are a lot of material. Take care not to confuse Swift language with SWIFT used in security and banking.

Can you explain the exact problem you have ? What do you get when you request an URL for download ?

Your url is a local file on your Mac. We cannot get it.

It is pretty hard to understand from the storyboard image. Please describe the full path that goes from root to the last VC: what are the types of each intermediate VC: NavController ? plain VC ? First seems to be a TabBarController. Exact ? Then you select second tab. Exact ? From there you go to a TableViewController. Exact ? 4th and 5th seem to be plain VC. Exact ? Which is HomeViewController ? how you navigate from each to the next ? Please explain in detail, show code if it is not a direct segue. In the small code snippet: let homeTBC = controllers![3] as! UITabBarController let homeVC = homeTBC.viewControllers?[0] as! HomeViewController self.present(homeVC, animated: true, completion: nil) In which VC is this ? I understand the last one ? What are controllers ? How are they defined ? Where are they defined ? What is controllers![3] supposed to be ? Which line exactly does the crash occur ? Could you post more of the crash log ? Please answer precisely to all questions if you want some help.

Where do you expect haptic feedback ? On the phone (but you left it behind…) on the watch ? Please be more precise on the use case. In any case, such a request should be sent as a Feedback, for improvement suggestion.

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.
