If not, will imaging via HFS+ (possibly converting to APFS afterwards) continue to be supported moving forward?Answer: Yes, ASR will continue to be supported.Question: Is fdesetup going to be the tool for interacting with APFS encryption, or will there be a new command line tool for managing APFS encryption? If there's a new tool, what is it?Answer: Yes, fdesetup is still the tool to use going forward.Question: Will the APFS per-file encryption / per-metadata encryption / per-extant encryption mechanisms each need their own recovery key?Answer: Full Volume Encryption for FileVault.

Move Group Crash Bug
Does anyone know a workaround for the well-documented bug that makes XCode crash whenever you move a group? This bug is reproducible 100% of the time and has been documented as far back as early 2017, yet I'm sure there must be a way to move a group. The only suggestion I've read is to turn off source control, but I'm unwilling to do so and lose my editing history. I've tried moving files into the group before moving it, moving it in different way, nothing works. And what's worse of course is that you have to reopen XCode twice after the crash to return it to a usable state.

Sign in with Apple for app group
I have a series of apps that use the same user database. With my Facebook and email/password logins this is easy to identify the same user. However, the sign in with Apple creates a different user_id for the same user across my group of apps. How do I allow the same user to login with the same user_id across the app group?

Single product in Subscription Groups
Hi iPhone Developper,This is Hayto from Tokyo, Japan. I am looking for how to make product without levels into subscription groups.As I am quoting as follows, I found the document which refers that we can make single product. But I can not find how we can set single product without levels into subscription groups or products with same levels.All subscriptions must be part of a group, however you are not required to differentiate them into levels. For example, you can choose to offer a single subscription in-app purchase, or you can choose to offer multiple subscriptions and assign them all to the same level within the group.URL which I quoted is as follows.https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnectInAppPurchase_Guide/Chapters/CreatingInAppPurchaseProducts.html#//apple_ref/doc/uid/TP40013727-CH3-SW10Could you kindly tell me how to make subscription product into subscription groups and how to make multiple products with same l

Unable to add build to group on testfight
In App Store Connect I've uploaded a new build, but I'm unable to distribute the App to my tester groups - including internal. The internal group is grayed out. I am able to Select an External group but they actually do not receive any email notification nor do they see any update within their TestFlight App. I've attempted to upload the build a few times, including old builds which had been distributed in the past to no avail. I'm not able to distribute to any tester group, please advise.

App Groups in Provisioning Profile
I'll preface by saying I am new to MacOS development. I've struggled with this issue for several days and have nowhere else to go for help. My MacOS app is an Electron build. It needs application-groups entitlement for IPC. But the developer portal, when generating the provisioning profile, always appends groups. to the start and I am unable to remove it. This renders my provisioning profile invalid and causes my app to be rejected by Transporter because it is not supposed to start with groups, but with my team identified for MacOS. Maybe I can still use the provisioning profile as is, but I've not found any way to do that. So I'm stuck unable to deliver. Any help with this is appreciated.

IAP subscriptions defaulted to different groups
Hi, In the new iTunes connect subscription groups feature, it seems Apple has defaulted to putting all of our In app purchase products into different groups. This is not what we want. We want them all in the same group so users can switch between them and we can maintain the 85% revenue share. I don't see any way to move subscriptions between groups. How can this be fixed? Thank you.

Running daemon with custom group id
Hi, I need to run a daemon helper(launchd) with a custom group id. For this I specify into the plist the group ID and everything works fine. The problems appear if I delete the group ID. Then the executable will not start anymore and if I want to send an XPC message remoteObjectProxyWithErrorHandler it will not return any error and the completion blocks are never executed. What would be the correct way to check handle the above situations? recreate group if it was deleted detect that the XPC connection cannot be established because the helper doesn't start Thanks

gesture control with groups
Hello, after a lot of trial and error, I managed to move/scale/rotate a simple object with gestures. In retrospect, it was actually quite simple. If you know how to do it. But now I have a new problem. Maybe you would be so kind again and help me. I took the Augmented Reality base file in Xcode (the one with the Experience.rcproject file in it). I entered this code in the ViewController: import RealityKit class ViewController: UIViewController { @IBOutlet var arView: ARView! override func viewDidLoad() { super.viewDidLoad() // Load the Box scene from the Experience Reality File let boxAnchor = try! Experience.loadBox() if let box = boxAnchor.steelBox?.children.first as? ModelEntity { box.generateCollisionShapes(recursive: true) arView.installGestures(.all, for: box) } // Add the box anchor to the scene arView.scene.anchors.append(boxAnchor) } } And it works. The object, that is the cube, can be controlled with gestures. Then I created a second object (I duplicated the cube) in RealityComposer (from Xcode), re
