So why do you think you need a privacy manifest for it? You've got the source. Edited to add: sorry, I see it is actually on the list at https://developer.apple.com/support/third-party-SDK-requirements/ . I find that surprising. Does it have a history of misbehaviour, or something?

I think that everything currently available will have similar levels of ongoing support. Breaks in support tend to happen when there is an architectural change, i.e. x86 to ARM and 32-bit to 64-bit. Don’t buy a used Intel mac obviously; otherwise get whatever you want.

In the past some apps have either added “do not buy” to the description or changed the price to $999. I don’t know if there is now a better alternative.

SwiftyJSON is an open-source thing from github, right?

I think it just let me “same here” your post while not logged in. Now I am logged in and tapped it, and it is spinning forever. Doesn’t that hand symbol.mean “stop” or “no entry”? It reminds me of American construction sites. https://www.dreamstime.com/stock-photography-stop-sign-construction-site-image21331712

do you mean I can add PrivacyInfo to the app project? Yes.

But what does "responsibility" mean? My guess is that in some sense in Brazilian law we developers are "responsible", so if Apple messes up and doesn't pay the right money, if we go on holiday to Brazil then we might get arrested. Because we're "responsible", not Apple. All of that document is legal verbage written to comply with each country's specific requirements, by expensive tax lawyers. You can essentially ignore it. The reality is that Apple collects all applicable taxes in all countries. It would be totally impractical for individual developers to try to interact with the tax authorities in every country where their apps are sold, and the tax authorities know that; they therefore require Apple to collect taxes, which they do.

Is there anywhere I can go to figure out the tax amounts? Apple’s tables show “proceeds”. The difference between what the users pays and proceeds is Apple’s commission and any taxes. I do not believe that they break that diwn anywhere, but you can estimate it quite accurately as the commission is always the same percentage. I just need something to reconcile I strongly recommend not trying to do your accounts at that level - it requires handling multiple currencies and varying exchange rates, which is a huge extra burden. In your accounts, just have a single monthly payment from Apple in your own currency, and just use whatever amount they actually pay. Don’t try to formally link that to your sales numbers in your accounts. P.S. I recommend not posting comments on this forum, they are easy to miss; post replies.

The important part is Exhibit C 2 A 2.3 : … which I was going to copy and paste, but I seem unable to copy from the PDF. Its says that Apple will pay the Brazilian tax authorities for you.

C code contains stat. Is this the same stat as Apple refers to?? Yes. How do you solve this?? You need to declare your reason for using stat() in thr app’s privacy manifest. It doesn’t matter that it is in a static library.

If you want to run Javascript with JIT on iOS, you can use WKWebView.

Apple handles all VAT and similar. As a developer you never need to be concerned with VAT or sales tax. (There may be exceptions in the case of your own country. Are you brazilian?)

It doesn’t look like a “fine line” to me - you’re not allowed to send the data off the device, except under the “bug reporting” exception, and that requires that the user interacts with the process of sending the report, not just silently sending the logs in the background.

It is possible to convert an individual developer account to a business account; you need to contact Developer Program Support. However I don't know what happens in the case where the old account has expired. Would it not be easier for you to create an entirely new account for the business? Is there content associated with the old account that you want to retain?

How exactly are you retrieving those values? This does work correctly in general, e.g. I've just checked on my iPhone XS running iOS 17 and got 4.2mm native and 26mm equivalent. Have you tested on any other devices?
