I'm running High Sierra 10.13.6 (that's the highest OS my computer will go to b/c it's a late 2011 pro). When I looked up what version of Xcode to get, I saw I needed to get Version 9.4.1 (9F2000) so that's what version of Xcode I have. As far as I checked, you can run Xcode 10 or Xcode 10.1 on a Mac running 10.13.6 . But if Xcode 9.4.1 is doing well with your C++ class, it would not make a big difference. I'm wondering if there's anything I can do to make it work ? What sort of debugging feature do you want to use? If you want to use some feature which are runtime-only, run your code. And you may need to learn that some of the features in the Debug menu are only for apps and you would not make them use in C++ code. So, again, what in the Debug menu do you want to use?

The dev forums is not the right page to write a feature request. You should better visit the Feedback Assistant and write feature requests there.

I don’t understand why the last two lines are taken as compile error. Can anyone help to explain a bit? You may need to know two things. In Swift, addition of Int and Double is not allowed. (The binary operator + is not defined for (Int, Double) nor (Double, Int).) In Swift, the types of literals are defined depending on the context. In your first example: 3 + 0.14 // allowed 3 is interpreted as Double (this may not be as you expect), 0.14 is interpreted as Double. The integer literal 3 can be interpreted both as Int and as Double depending on the context. In this declaration: let three = 3 The type of three is inferred as Int, as there is not type hint in the declaration. And the type of rest is inferred as Double. In the following line, 3 is inferred as Double again in this context. 3 + rest // allowed Thus, the last two lines causes error: 0.14 + three // compile error three + 0.14 // compile error Because type inference of three is finished here and it has the fixed type Int.

It is a known issue that Apple Pie thing does not work well with Xcode 13. (It is very easily reproducible with creating a brand new project in Xcode 13.) These are some example threads: Guided Project: Apple Pie Apple Pie Guided Project: getting error - Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value.

As far as I tried, XMLParser (NSXMLParser) did not work as you expect, even if implementing parser(_:resolveExternalEntityName:systemID:) and/or setting shouldResolveExternalEntities = true. You may need to work with libxml2 directly or find another library to parse XML including HTML entities such as rsquo.

Can you show your current code? One more, you should better respond to the comments and answers to communicate better in the dev forums.

You should better try the Feedback Assistant. It is not only for bug reporting, but you can use it for feature request.

i get error that says Segnentation fault: 11, Generally, stopping with Segmentation Fault 11 is caused by some bug of Swift compiler. (You should better send a bug report to bugs.swift.org .) And in most cases, you can avoid this sort of bugs by fixing some sort of bugs in your code. It depends on many things, but if all your hidden codes are as I expect, it should be something like this: CLGeocoder().reverseGeocodeLocation(CLLocation(latitude: self.parent.source.latitude, longitude: self.parent.source.longitude)){ (placemarks, error) in if let error = error { print(error) return } guard let placemarks = placemarks else { print("placemarks is nil") return } if let pm = placemarks.first { self.parent.userLocation = (pm.subThoroughfare ?? "") + (pm.thoroughfare ?? "") + (pm.locality ?? "") } } (When showing some code, please use the Code Block feature. And better make parentheses balanced.) Generally, you should better avoid using forced something (forced unwrapping !, forced casting as! and implicitly unwrapped Optional !) as far as you can. Please try the code above.

Please check this post. I guess Apple's App Store Connect server is getting unstable. (This often happens on big events, such as WWDC or the release date of new iPhones. I do not understand why today.) Try a few more hours later and see what happens. (Please share the result.) If the issue goes on longer, you should better Contact To Apple.

Is this the App Store's fault? Very probably. What should I do? You may need to just wait until the unspecified general error is fixed. Usually this sort of errors will be fixed in hours, when unlucky a few days. By the way, you should better use the right tag. XcodeKit is not appropriate for this issue. You can use the tag App Store Connect.

Can you show more context? What is the problem running your app on iPadOS 15?

Can you show enough code to run and test? Hard to say something with just fragments of code.

Thanks for showing your code. (And sorry for this site malfunctioning again.) But if you could show enough code (the view type containing the VStack, what settings is, what Setting is...), more readers would be involved to investigate what is happening. Anyway, I could have confirmed the difference. This seems to be a bug of Slider in iOS 15. Have you sent a bug report to Apple? And unfortunately, I cannot find a simple workaround for this issue as for now.
