Having issues authorizing payment for Apple Developer Program

Hey guysI’ve been trying to pay for Apple Developer Program enrollment for about a week and still no luck. As well as I got from a small talk with the customer support – Apple never got my money. So it seems like my payment authorization fails all the time. But I don’t know what’s really going on.Have any of you ever had issues like that?Or maybe you just know what’s going on and how to fix it?

Using Core Data with SwiftUI App Protocol

Is it possible to use CoreData with the newly announces SwiftUI App Protocol for 100% SwiftUI apps. If I need to create an app with persistant storage, is there a way to achieve this with the new protocol? I like the idea of having my app fully compatable across all systems. Thanks.

Installing macOS Big Sur beta

I installed the profile for macOS Big Sur, but I got updated to Catalina beta 10.15.6 beta instead. Is it possible to install the Big Sur beta already?

SwiftUI isPlaceholder not showing

I'm following the Widgets Code-Along and at the end of part 1 Izzy uses .isPlaceholder as an easy way to show the widget placeholder but when I try it, it doesn't seem to be available yet. Am I missing something or is this feature coming in a future beta?

Parallels 15 (Mac): Updating macOS Catalina Beta to Big Sur Beta

When I select the main disk to install to, I get the error message: "The operation couldn't be completed. (BIErrorDomain error 3.)" Has anyone else experienced this? I wanted to try out the Big Sur beta, but didn't want to risk rendering my daily MBP unusable. Thanks!

Big Sur Beta 7 breaks SMB?

After the upgrade from Beta 6 to Beta 7 I am not able to connect to any smb-shares any more. I tried it with a Windows Server, Synology DriveStation and a Debian implementation. I'm directly getting the message Error with connection.

Collapse sidebar in SwiftUI (Xcode 12)

I'm trying to do a simple application in SwiftUI taking advantage of SwiftUI 2.0's new multiplatform project template, and I wish to add the option to collapse the sidebar as many other apps do. I've got an extremely simple sidebar I did following the Fruta example project, and I tried adding a boolean state variable that controls whether the sidebar should show or not, but that doesn't work because when the sidebar is hidden, the main view is turned translucent. On iPadOS, a button appears on top of the sidebar that allows to collapse it. How would I do this in macOS? Is there a way to natively achieve this in SwiftUI, or I'll need to resort to a UIKit workaround?  Please note I'm using macOS Big Sur, Xcode 12, and SwiftUI 2.0 Thanks in advance.

What are the downsides to using lazy stacks?

In Stacks, Grids, and Outlines in SwiftUI - https://developer.apple.com/videos/play/wwdc2020/10031, a recommendation is made to only use lazy stacks when you encounter performance bottlenecks. To quote the session, starting at 4:43: On the other hand, making the stacks within a given hero view lazy doesn't actually confer any benefits. The content is all visible at once, as soon as the view lands on screen. So everything has to be loaded at once, regardless of the container's default behavior. If you aren't sure which stack to use, use VStack or HStack. Adopt lazy stacks as a way to resolve performance bottlenecks that you find after profiling with Instruments. Are there negatives, performance or otherwise, to just always use lazy stacks? I'd like to understand why I shouldn't reach for LazyVStack and LazyHStack first. I understand from the example that using a lazy stack wouldn't confer any benefits, but would we incur any negatives?

SwiftUI Version

Is SwiftUI currently versioned like Swift the language or is treated more like UIKit where the version is attached to the OS release? So for example will the changes to SwiftUI found in Xcode 12, work on iOS 13? If not that means any new SwiftUI features/bug fixes will need to wait to be deployed until iOS 14 is released AND there is enough iOS adoption by the user base. Thanks.

Why is my provisioning profile failing qualification?

I am ready to upload my app from Xcode to App Store Connect. I am using Xcode 11.50 to archive my application. Yesterday, I used Xcode 12 Beta to upload the app, which worked fine at first, but noticed that App Store Connect is not accepting binaries from Xcode 12 Beta. I used Xcode 11.50 today and I keep getting this error while validating my app: Provisioning profile failed qualification: Profile doesn't include the com.apple.application-identifier and com.apple.developer.aps-enviornment entitlements. Provisioning profile failed qualification: Profile doesn't include the com.apple.application-identifier entitlement. What exactly do these errors mean? How can I fix them?

SwiftUI Previews not working with Firebase

SwiftUI previews don't seem to work in Xcode 12, beta 5, when using Firebase Analytics. The app builds and runs fine to simulator or device, but fails generating SwiftUI preview for a widget with the following message: ld: in /Users/../.../Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector(FIRAnalyticsConnector_e321ed8e3db06efc9803f6c008e67a34.o), building for iOS Simulator, but linking in object file built for iOS, file '/Users/.../.../Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector' for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) It was working fine in beta 4. Anyone else seen this? Any ideas?
