You're probably right from previous post. But he/she should be more explicit…

Thanks for feedback. In fact the key was id = UUID(). It seems you never use index ? Otherwise, this is probably a typo: index: "2, id: 2"

Yes, using func is much easier. But your question was a challenge to find a way to express it as a var. Good continuation, don't forget to close the thread. It may be of interest of others to see there was a solution tou the question, even though too complex for the benefit.

If you can't rely on simulator running on Mac, you may need to find an iPhone with older iOS version.

Thanks for feed back. It was effectively a bug. You close by marking the answer you consider correct (the circle with the √ sign below the up and down arrow next to the answer. So you can also close your bug report.

No, it should support 15.4.1 as well. Contact support.

Thanks for the feedback. I had the same feeling when starting of others experts (on this forum notably) knowing so much more than me.I learned first from books, then by practicing. I used forums a lot. I followed online courses (Stanford iOS is excellent, but there are others) ; when I had an issue and most important, I took time to read technical articles for in depth understanding (Ray Wanderlich is excellent at this). So, just be curious, don't simply copy code for a quick fix but understand what it does, why it works and why previous code didn't. Good continuation and enjoy.

You welcome. Don't forget to close all your threads by marking the correct answer.

I think it is not possible to limit other apps, unless you are in an MDM or equivalent scheme. And that's logical. Would you want some competitor be able to limit the use of your app on a customer device ? Not me.

What you show is not exactly matching the code you posted. It says Trade value vs Dividend value. Could you also post Dividend definition ?

@ Richard_Klug where does it crash ? did you read eskimo answer on how to form url ?

Normal, I changed to have first letter as lowercase (calculator vs Calculator, calculated vs Calculated). So, you need to change it everywhere in code.

Thanks for feedback. I suppose you don't use this framework just for the initial question. If hiding was not a good option, you could have removed and reloaded views A/B/C when needed

If you show the code you tried, maybe someone can help…

Another way is to create an id = UUID() in the struct, instead of num. And create with simply MyEmoji(char: "🐶") and use .id instead of .self.
