Dear Experts, Is there a way to create a new target in Xcode that is a copy of an existing target? Specifically, I have a standard iOS app target in the project. I'd like to build a second iOS app by adding a second target to the same project. I'd like it to start as a copy of the first target, and then I'll add and remove source files and frameworks, change assets and settings etc. It seems to me that I have to create a new target and then add all the source files etc to it, and then replicate all the settings. I've tried to do this, but it isn't working - bizarrely I just see a black screen, though log messages suggest that the app is running. I am unsure about whether the two targets are sharing e.g. the Info.plist file, etc. Any advice? Thanks.

Is it possible to change the date formats used in the App Store Connect web interface? It seems to me that things like the date range selection widget on the Sales & Trends page use only the US-style MM/DD/YYYY format. Is there some way to change this to YYYY-MM-DD or DD/MM/YYYY that I have missed?

Dear Experts, NSLocale has a notification NSCurrentLocaleDidChangeNotification and a property autoupdatingCurrentLocale ("A locale which tracks the user’s current preferences"). These suggest that an app should be able to detect when the user changes their language preference while running, or when it is resumed from the background. In practice, when I change language in the Settings app (either globally or just for my app), the app is terminated by iOS and restarts with new locale. Is this the expected behaviour? I am wondering if there is something I need to do to advertise that the app can adopt language changes without restarting, or something. Maybe only date-time formats, etc., trigger the notification but language changes don't?

6.7-inch screenshots have become compulsory at some point since I last created an app update, and I will need to purchase a new device to satisfy this requirement. The App Store Connect media manager says that 6.7-inch screenshots must be 1290 x 2796 pixels. Looking at device specs (e.g. at everymac.com), it seems that this is the size of the iPhone 15 Pro Max, iPhone 15 Plus and iPhone 14 Pro Max. However the iPhone 14 Plus and older are fractionally smaller at 1284 x 2778, despite also being described as "6.7-inch". Does anyone know if App Store Connect will accept 1284 x 2778 screenshots for the "6.7 inch" category? A refurbished iPhone 12 Pro Max is about half the price of an iPhone 15....

Dear All, I have a paid app which has in-app purchases to unlock additional content. In my App Store screenshots and preview videos, I used to indicate which content was paid and which was free with labels superimposed over the screen captures. App store review guideline 2.3.2 supports doing this - in fact, it seems to require it: 2.3.2 If your app includes in-app purchases, make sure your app description, screenshots, and previews clearly indicate whether any featured items, levels, subscriptions, etc. require additional purchases. But App Review don't like it. Some years ago they complained about the labels on the screenshots, which I removed. Now they are complaining about the preview videos. They cite guideline 2.3.7, which says (in part, my emphasis): 2.3.7 ... Metadata such as app names, subtitles, screenshots, and previews should not include prices, terms, or descriptions that are not specific to the metadata type. ... So these guidelines seem to be contradictory. If I label a screenshot as "free" or "paid", they consider that to violate 2.3.7. (I'm not showing an actual "$1.23" price, just "free" or "paid".) But I need to indicate whether the content shown is "free" or "paid" in order to comply with 2.3.2. (And I want to label it as such, because I don't want users to misunderstand what is included with their initial purchase.) Has anyone else had this problem? I wonder if there is some particular wording that they require, e.g. "Requires in-app purchase" rather than "Paid". Or something rather than "free". There is a limit to how much text I can legibly add without obscuring the actual content, so I have tried to keep it brief. I did refer to 2.3.2 in my reply to App Review, but they haven't addressed that; they've accepted the update as a bug fix. Ultimately I'll just do what they want - it always seems easiest - but I do have real concern that my customers are worse off without these annotations.

In my Mac's Settings -> General -> Storage -> Developer -> (i) I have a series of entries for "bridgeOS", all 2.49 GB except one that is "zero". Do I need these? Can I remove them? I am only doing "normal" iPhone / iPad development. (There was some previous mention of this here: https://developer.apple.com/forums/thread/711279 with no feedback.)

If I use UIEditMenuInteraction to present an edit menu, it has a dismissMenu method that I can call to remove the menu when necessary. When I use UITextInteraction, I get an edit menu automatically that is normally presented and dismissed at appropriate times. But sometimes I want to dismiss the menu myself, and I can't find a way to do that. Am I missing something? I was hoping to find that UITextInteraction inherited from UIEditMenuInteraction, or had some other way to access the underlying menu in order to dismiss it. But it seems that the menu must be a private part of the UITextInteraction implementation. The particular case that I need to deal with is when I call resignFirstResponder. This seems to cause the keyboard to close and the insertion point and any selection to be hidden, but if an edit menu was shown then it remains visible (a ghost!). If anyone knows of an alternative to resignFirstResponder that will make UITextInteraction tidy up properly, that would also be useful to know. Thanks for any suggestions!

Does anyone else use the "Download CSV" button on the Search Ads website's billing page? I used to use this successfully to download files that I could import into my accounts database. But when I tried it today, the file it returned was an XLSX. Has anyone else seen this? Any work-arounds?

I have a simple Safari extension which contains only Javascript and no native code. Currently I have the placeholder SafariWebExtensionHandler.swift that Xcode created when I added the extension. It's not doing anything useful, but simply deleting it doesn't seem to work. Can I have an extension that includes no native code?

Is this symbol, which Safari uses to the left of the address bar, in the public SF Symbols set? What's it called?

Is there a recommended way to determine whether to use the development or the production server API endpoint for DeviceCheck? For App Attest, the authenticator data includes either "appattest" or "appattestdevelop" in a field of the cbor data. For IAPs, we're supposed to try the production endpoint and then retry with the development endpoint if we get a particular HTTP status code. But the docs for DeviceCheck say only to use the development endpoint in development and the production endpoint in production. What are others doing? Is there any clue in the docs that I have missed?

Dear Experts, Where is the best place to persist an App Attest key id? The docs ( https://developer.apple.com/documentation/devicecheck/establishing_your_app_s_integrity ) say “Record the identifier in persistent storage — for example, by writing it to a file”. That is what I have done, but I have encountered a problem. If a user gets a new device and restores a backup of an old device onto it, the new device will try to use the key id from the old device - which is of course wrong. One solution is to detect the error when the invalid key is used and to generate a new one. Is that the best approach? I am wondering if there is some part of the filesystem that does not survive the backup/restore process, but is otherwise persistent? It should be more persistent than a cache file. (Also looking at the docs again I now see that I am supposed to store distinct keys for each “user”. What is meant by “user” in this case?) Thanks.

Does anyone know the relationship, if any, between Xcode's static analyzer and clang-tidy? I.e. is Xcode's Analyze feature actually invoking a built-in clang-tidy? If not, does anyone have any experience using upstream clang-tidy (homebrew?) with a mostly-Xcode development flow?

Dear Experts, What is the current best practice for build numbering? I ask because I am aware that when exporting an archived app for upload I am now asked if I want Xcode to manage the build number for me. In the past I have set a build number in the Info.plist, often based on the date, e.g. 2.4.20230218. Now, I am asked if I want that to be replaced by something like 2.4.7 (if I recall correctly). So far I've answered No. Previously I have searched for automatic build numbering and I've found web pages that suggest adding a script to the build process that automatically increments the build number in the info.plist, or similar. I've not tried to implement that myself. In some of my apps, I have code that needs to know the full version at compile time (e.g. app receipt validation). How would that interact with the new feature? Thanks, Phil.

Dear Experts, I am confused by what seems to be a difference in behaviour of the Files app on an iPhone compared to an iPad. On the iPad, I seem to be able to view my app's Documents/ folder; on the iPhone, I can't. On the other hand I can access the app's iCloud documents on both devices. Is this the expected behaviour? If so, what is the rationale? Thanks, Phil.
