From time to time while I'm editing code, Xcode 15.0.1 says "The file 'project.xcworkspace' has been modified by another application" asking me "Keep Xcode Version" or "Use Version on Disk". I didn't see this before 15.0.1 (or 14.1.1). Who changed the file? What should my answer be? Thanks.

I can't locate the Remove button in Xcode 15 to remove the old build before adding a new one. Can you point me to the instructions for removing the old build? Thanks.

I updated iPhone to iOS 16.4. Xcode told me to update to 14.3. Now Xcode won't open because I need macOS 13.0, but my 32GB iMac Late 2015 won't take 13.0. Are my days as a developer over? Is it possible to go back to old iOS and old Xcode? Would that solve the problem?

My app works fine on any iPhone and iPad, but the poor iPod screen is just too small (I can't scrunch it down any more). What do I set to tell the App Store that an app doesn't run on iPod? I haven't found an AppName-Info.plist item for this purpose. Thanks.

I get this error message with Simulator, but not with hardware: Domain: IXErrorDomain Code: 13 Failure Reason: Missing bundle ID.

I had a problem with my in-app purchase, so I deleted it in Xcode/project/TARGETS/myapp/Signing & Capabilities. To recreate it I click on "+ Capability", the Capabilities window comes up, on the left I select "In-App Purchase", "In-App Purchase" appears on the right side, I click back in the main window, but nothing happens. This is how I added it the first time. I've tried restarting Xcode. Shouldn't I be able to delete the in-app purchase in Xcode and add it back? All looks right in App Store Connect; I had it almost working correctly. Any clues how to fix this?

If a user has already In-App paid for my app and then deletes it before the subscription runs out and downloads it again, and since my app doesn't keep subscription data in the keychain (which remembers only when the app was downloaded), my app starts the subscribing process. When Apple sees the subscription request, will Apple tell the user that it's already been paid for? I don't see this behavior in the sandbox.

In Certificates, Identifiers & Profiles, Edit your App ID Configuration, do I create here a Bundle ID for my app's in-app purchase? There is already a Bundle ID there for my app.

In sandbox testing, I was able to get auto-renewing subscription to work, but decided to switch to one-time in-app purchase. I've read many how-to's, but I'm missing something. My app has Bundle ID com.myname.id1 and IAP capability added. The IAP has Product ID com.myname.id2. My agreements are up-to-date (auto-renewing subscription worked). The In-App Purchases screen lists my IAP under "Drafts (1)"; is this expected? "[SKPaymentQueue canMakePayments]" returns true. "[[SKProductsRequest alloc] initWithProductIdentifiers:set]" (where set contains "com.myname.id2") responds to "[request start]". In the delegate, "NSArray *product = response.products" comes back empty. Does the IAP have its own Bundle ID? What am I doing wrong? What have I not told you that's important? I've been stuck for a few days on this. Thanks!

My company, though not a corporation or LLC, is officially registered with the Oregon Department of Corporations and has an official certificate which allows contracting with the state. This is not a county DBA; the term DBA does not appear. Can my company name be my app publication name in the app store?

When an iOS app is launched, how does it learn that its subscription (or free trial period) is no longer active? Must the app poll the App Store every time it's launched?

I have a working Main.storyboard and want to add a launch screen. I followed the tutorial at https://stackoverflow.com/questions/31676901/ios-8-launch-screen-storyboard-appears-black-single-xib-file-works-fine/65693691#65693691 and got my launch screen working, except that it hangs and doesn't progress to Main.storyboard. Is a navigation controller (which I haven't added) required to move from LaunchScreen to Main, or is some setting wrong that causes the hang (and what might it be?)? Thanks!

After an upgrade of some kind (Xcode, iOS, ??) my app no longer loads onto my iPhone 11. I generated a new development.cer and double-clicked it. What's the next step to get my app to run on iPhone? It has been working for years, but no more. It runs fine in the simulator. Thanks.

My app works properly, but adding Launch Screen.storyboard, all is fine up to and including adding Image View to View; I still see the background color of View and my annotation. But when I select my photo IMG_1486 (which is file IMG_1486.png) in Image, the screen turns black. The png is fine; I can point Main.storyboard to it and it shows up correctly. What settings can cause the black launch screen in this scenario? Thanks.
