I'm getting this message when I try to install Xcode, it says there is not enough disk space.I checked my main volume and there is 60GB available.I'm assuming that Xcode can't possibly require more than 60GB and that this message is a mistake. How do I fix it?Thanks,Frank

I've seen examples of Swift code with #if DEBUG / #endif, and have even used it myself.I know exactly how preprocessor macros work in c, c++ and Objective-C. In those languages, I know I can say:#ifdef DEBUG ... some code ...#endifAnd I know that if the DEBUG flag is false at build time, the code will not only not run, but it won't even be compiled. This is important to me because the code inside that block contains some sensitive information that must not end up in my compiled code for non-debug builds.In Swift, I'm really not sure what happens. I know the code doesn't execute, but I'm also told that Swift doesn't have a preprocessor. So, what exactly is going on here?Specifically, can I hide sensitive information inside an #if DEBUG block in Swift and be assured that it won't get compiled or in any way be present in the executable when the DEBUG flag is false? Or is #if DEBUG evaluated at runtime in Swift?Thanks,Frank

We have an auto-renewable subscription in our app that we want to stop offering. However, we want to make sure that people who have already purchased the subscription remain subscribed until the end of their current subscription period (and are subsequently unsubscribed and not charged further). What is the right way to do this?We tried submitting the app with the subscription still enabled in App Store Connect but hidden in the app, and our update was rejected because the reviewer couldn't find a way to subscribe.Thanks,Frank

I'm trying to save a Dictionary to UserDefaults. My Dictionary is defined as [String:Data]. Since both String and Data are property objects, I expected this to work, but it doesn't: my app blows up with a "this class is not key-value coding compliant" error. Is this a bug, or am I doing something wrong?

I want to send my app silent push notifications while it is running in the background, but I've been unable to get it to work. I understand how to send the notification by setting the content-available flag, and I've implemented the "didReceiveRemoteNotification" function in my app delegate. It works, but only if the app is open and running in the foreground. As soon as I put it in the background, didReceiveRemoteNotification doesn't get called again unless I reopen the app. I feel certain that I should be able to receive these notifications when my app is in the background. I have both "Remote notifications" and "Background processing" checked in Signing & Capabilities. Thanks, Frank

I'm working on a BLE app with a hardware partner using samples of their device, which I am able to erase and re-flash when needed. When I try to use the device it initially works fine. I can connect to it, make requests, and get back responses. However, after a short time and a few successful runs, I start getting the error "Encryption is insufficient". The error is seen in the "didUpdateValueFor" function. I can still connect to the device, and enumerate all of its services and characteristics, but I can't read any data. If at this point I re-flash the device and also go into the iOS setting app and "forget" it, then I can use the device normally again, at least for a while. What causes this? Is there a way I can fix it in my app? Thanks, Frank

I'm not getting any values from the floorsAscended or floorsDescended properties of CMPedometerData. I tested it by walking up and down a flight of stairs twice while monitoring for pedometer updates for 60 seconds. I also queried for the pedometer data separately at the end of the time period in case there were any updates I missed. I'm using an iPhone 13 pro for my tests and I did check to make sure CMPedometer.isFloorCountingAvailable() is true, and I am getting other kinds of pedometer data such as distance, pace, and steps. Is there something else I need to do in order to enable floor counting? Thanks, Frank

I added this file as Apple requested due to my app using UserDefaults, but it still complains when I upload it. This is the message: TMS-91053: Missing API declaration - Your app’s code in the “Production” file references one or more APIs that require reasons, including the following API categories: NSPrivacyAccessedAPICategoryUserDefaults. And this is my file, what's wrong? <dict> <key>NSPrivacyAccessedAPITypes</key> <array> <dict> <key>NSPrivacyAccessedAPIType</key> <string>NSPrivacyAccessedAPICategoryUserDefaults</string> <key>NSPrivacyAccessedAPITypeReasons</key> <array> <string>CA92.1</string> </array> </dict> </array> </dict>

I have a new app that needs to be submitted for review this week. When I tried to submit it, I was told I could not do so because "Under the Digital Services Act, you must provide and verify information regarding your account". I am working on behalf of a large corporate customer. They are telling me that they cannot do anything without consulting their legal team, which is going to take time. In the meantime, they asked me if I could omit the European region from the app's distribution list. I tried this, but it did not work. I manage about 20 apps for different customers and I have never seen this requirement appear on any other account. Is it new? Does it only apply to certain kinds of accounts, or to new apps, or new accounts publishing their first app? If this is a European Union requirement, why is it needed if I don't distribute to EU countries? Thanks, Frank

I'm assisting a customer with an iOS app. He has a personal (non-company) Apple Developer account. I know that this kind of account didn't used to support collaborators, but I'm not sure what the current status is. He was able to add me to his account and give me permissions (Developer, App Manager). However when I run Xcode, his account does not appear in the list of Teams under my Apple ID, which is preventing me from working. Is this a bug or temporary problem or is the fact that his account is a personal account preventing me from doing this?

Hi,One of my external testers wants to run my app on a second device.He asked me to please send him another invitation for the second device. I don't know how to do this. If I try to add his email address again, nothing happens. If he tries to re-use the original invitation, it doesn't work.How do I invite the same person to test on a new device? Does he need to get another email address?Frank

Hi,I'm having a really weird problem. Brand new project, using a UINavigationController. I want to set the background color of my navigation bar to match the background color of my root view controller.I thought that this was the right way to do it: [[UINavigationBar appearance] setTranslucent:NO]; [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0x2d/255.0 green:0x55/255.0 blue:0x97/255.0 alpha:1.0]];However, this generates a navigation bar with a color value of #234185 instead of the expected #2D5597. What is the explanation for this, and how do I fix it?Thanks,Frank

Hi,I'm working with subscriptions.How do I know when a subscription expires, or is cancelled by the user? Does Apple push this information to my app automatically, or do I have to execute a command such as SKReceiptRefreshRequest or restoreCompletedTransactions?What is the difference between requesting a receipt refresh and restoring completed transactions?Thanks,Frank

Hi,Is it possible using MusicKit to play songs through audio filters, such as pitch shift or time stretch filters?Is it possible to play two songs at once for the purpose of fading between them?Is there a way that I can access tempo information about songs?Thanks,Frank

Hi,I'm familiar with the "willTransition" method of view controllers that lets you detect when a transition to a new UITraitCollection is about to begin.What I need is a callback that happens after the transition is finished. There doesn't seem to be any "didTransition" method, nor any delegate property on the UIViewControllerTransitionCoordinator that I can use for this.How does one obtain this callback?Thanks,Frank
