One more observation: always work with local copies of anything that should not be changed externally. I am surprised that this isn't what happens in the compiled code anyway. I.e. given your source code v -= d; if (v < 0) v = 0; if (v > 180) v = 180; f(v); I would expect the compiler to generate code that keeps v in a register through all of that and not read and write to the global variable location, i.e. in pseudo-assmbler: reg = load(v) reg = reg - d compare reg, 0 if less reg = 0 compare reg, 180 if greater reg = 180 store reg to v move from reg to function arg location (if different) call f In that case, there is no opportunity for the concurrent invocation of the function to modify the value of v between the clamping tests and the subsequent use. Maybe you have compiled with no optimisation? Maybe your real code is more complicated than what you've posted? Anyway, I suggest that you look at the generated code (if you can work out how to do that) and see if it is really doing what you think it is doing.

Do we know if this is something that can be fixed in an iOS 12.x+1 release, or in an XCode 15.x+1 release? It seems that binaries created with Xcode 15.1 work OK on iOS 12 without the need to specify -ld_classic. I don't know if this is because the underlying problem has actually been fixed, or whether it now just uses ld_classic by default when the target is iOS 12.

The only case in which this could crash is if two instances of my function are ran concurrently, which does happen during heavy load Well done for debugging that. The traditional fix would be a mutex that protects value. I guess that the "modern Swift / Apple way" to do this would involve a serial queue. Moral of the story: always work with local copies of anything that should not be changed externally. That's not necessarily sufficient for correctness.

Sometimes you can find the transcripts for deleted WWDC videos at archive.org. But frankly, do you really want to start using an Apple technology in these circumstances? Have you looked at the alternatives?

I still can't get this to work. I clicked on the "GET" button in the Platforms screen's "iOS 17" row, as shown in the second screenshot above, and it downloaded 7.56 GB again... and still shows that row greyed out. Then I clicked on the "GET" button in the run destinations popup (visible in the first screenshot above), and it immediately displayed the small "downloads" window with that download completed: ...but the popup still shows "iOS 17.0 Not Installed". This is starting to look like an Xcode bug - I've deleted something that I cannot recover from. Will I have to re-install Xcode? I should mention that this is Xcode 15.0; maybe this was fixed in 15.0.1 or 15.1?

I'm not certain, but I think they are equivalent I think I was wrong, at least for 17.0. If you right-click on a row in that platforms list, you can copy some more detailed text that should show you exactly which version it corresponds to. Doing that, my "iOS 17.0" entry describes itself as "SDK + Simulator", while my "iOS 17.0 Simulator" entry is just "Simulator". Maybe 17.2 is different. See my other thread: https://developer.apple.com/forums/thread/743144

Frustrating! I attempt to run on an iPad with iOS 17.1.2, but I can't because I see this in the run destinations menu: Note "iOS 17.0 Not Installed". In Xcode -> Settings -> Platforms I have: Note this claims that I have "iOS 17.0 simulator" but not "iOS 17.0". I attempted to download "iOS 17 Simulator Runtime" from https://developer.apple.com/download/all/ and install it following the instructions at https://developer.apple.com/documentation/xcode/installing-additional-simulator-runtimes: % xcrun simctl runtime add Downloads/iOS_17_Simulator_Runtime.dmg D: B9B832F1-6DE0-4A73-8756-1CB9BB19C25A iOS (17.0 - 21A328) (Unusable - Other Failure: Error Domain=SimDiskImageErrorDomain Code=5 "Duplicate of 7A4EF297-D25A-425A-8DF5-0E977B76C201" UserInfo={NSLocalizedDescription=Duplicate of 7A4EF297-D25A-425A-8DF5-0E977B76C201, unusableErrorDetail=}) Hence the red item in the Platforms window. It is suspicious that the "iOS 17.0" and "iOS 17.0 Simulator" are apparently both 7.56 GB, yet there are not the same thing. (Edited to add: right click and "copy version information" reveals that indeed "iOS 17.0" is SDK + Simulator while "iOS 17.0 Simulator" is only Simulator, despite apparently being the same size.) I guess that if I click GET in the Platforms window it will download the right thing, but I would much prefer to download a .dmg which I can then copy to my other Mac; I have a slow internet connection. In fact I did click GET earlier and cancelled it, and BOTH the "iOS 17.0" and "iOS 17.0 Simulator" rows in the Platforms window showed download spinners, as if they are actually the same thing. I only got in this mess because I was attempting to delete support for old point releases that I don't need anymore, and thought that 17.0 was one of them. Suggestions anyone?

I'm not certain, but I think they are equivalent. The previous use of the word ¨simulator¨ gave the impression that it was, well, just the simulator, and that it was not what was needed to compile for actual hardware. (I had to ask here for clarification.) Now maybe they´ve removed that word to remove potential confusion. The fact that both downloads are about the same size suggests that they contain similar content.

@Richs-MacBook-Pro ~ % rsync -arv --delete /Volumes/Samsung_T5/LRPhotos-T5/ /Volumes/QNAP-USB-2/LRPhotos-T5/ sending incremental file list rsync: [Receiver] mkdir "/Volumes/QNAP-USB-2/LRPhotos-T5" failed: No such file or directory (2) Presumably /Volumes/QNAP-USB-2/ is supposed to be the NAS. (Is it actually networked, or is it a USB device as the name suggests?) But rsync thinks it doesn’t exist. So maybe that’s not the correct name, or it’s not mounted, or something. In any case, this usage is not exploiting rsync’s incremental protocol. For that to work, you need to actually run rsync over the network to the NAS. Example: rsync -ar /path/to/local/folder/ nas_hostname:/path/to/folder/on/nas

Does Appstore Display your address publicly No. There was something odd about users in Korea at one time. Not sure of the details. (Always subject to change of course.)

My app name "Freepaystubnow" is one word and it's not indicate any price It includes the string "Free". It seems that having that anywhere in your app's metadata will result in rejection. You will need to change it.

4 months ago: I was not aware there was a direct way to post bug reports. Thank you so much for sharing! Today: Have you guys, ever wished, so hard, to give a collective "f****k you" to a whole company Thanks for your feedback about the "Feedback Assistant" experience. So that we can be sure that your feedback reaches the right people, I’d appreciate you filing a bug about this. And please post your bug number, just for the record.

Is there a better solution? No.

its an emergency Tell us the story! Do you live somewhere that is subject to embargo / sanctions? If my game is free and it runs ads, who is paying me? apple or google? in my case(google ad program). Google obviously. Can I give them a revolut iban? If "them" == "google", this isn't the best place to ask. Anyway, have you searched the forum for "revolut"? There are some posts. then the topic is forgotten. Yes, this forum is pretty useless. Just look at the vast number of questions with 0 answers. Maybe there are other places to ask where you would get better answers.

I've asked App Review to comment: There seems to be a conflict here between guideline 2.3.7 (screenshots and previews ... should not include prices) and guideline 2.3.2 (screenshots and previews clearly indicate ... require additional purchases). My guess is that you specifically object to my use of the word "free" to indicate content that does not require in-app purchases. If this is the case, could you please suggest what alternative would be acceptable? I suspect that you would accept a verbose expression such as "no in-app purchase required for this content", but that is not practical in a screenshot or video. How about "not paid"? Or "included"? Do please at least confirm that it is specifically the word "free" that I need to change. Does anyone here have a suggestion for a synonym for "free" that App Review might not object to?
