Reply to Create with Xcode 27 → submit with Xcode 26?
In the Xcode Group Lab they state that Xcode 27 projects are compatible with Xcode 26 except for one project setting check box Strictly Validate You will also need to set the Minimum Deployment version to 26.0 or earlier. If you use an API not available in your minimum deployment version you will get an error. if #available(macOS 27.0, *) You cannot add an if available conditional check because macOS 27.0 is not defined when open the project in Xcode 26. My suggestion would be to comment out the API you would like to use with a note and use an older API. Then when Xcode 27 is released for submissions you can uncomment it and use an if available test.

Reply to UITabGroup child tabs ignoring viewControllerProvider in Sidebar
This is the default behavior for how UITabGroup works. To get enhanced view controller management through a UINavigationController stack, use the UITabGroup.managingNavigationController API. There's a little more description of how that works on the following answer in another post in the forum; or check out the WWDC25 - Make your UIKit app more flexible video.

Apple Appstore Summary Sales Report API updates historical reports without notification
I've had several internal users note that the Summary Sales report API has started to have updates to historical reports. As an example - a subscription quantity might be 1 when the API is queried for 1/15/24, but then if the API is queried and reconciled against itself it might be quantity of 3 when pulled 3/15/24. This only started after 1/1/24, so I am wondering if there was a change to the report logic, or a new policy that Apple has started to allow that is making backdated changes to the summary sales report. This is causing a lot of potential missed revenue and manual effort for our accounting teams. Is there any guidance that Apple team or others can provide on this topic?

In-app purchase multiple subscription groups
I'm trying to figure out how to proceed with multiple subscription groups with iOS in-app purchase.Suppose I have multiple content providers users can subscribe to, and for each there are different tiers of subscriptions as follows:Provider 1 : Basic, Plus, Premium Provider 2 : Basic, Plus, Premium ... Provider n : Basic, Plus, Premium.My understanding is we do this by creating subscription group and within each subscription groups create Basic, Plus, Premium. Users can upgrade/downgrade plan within the group.My issue is we add/remove content providers all the time, therefore its not scaleable to keep adding new subscription groups every time we have new provider.

iOS iMessage Group Message Limitation
Hi, I have iOS 13.6.1 installed and I have a group message that I want to add additional contacts to. The original group message was sent to both iPhone and Android phone users. I Googled how to add additional contacts to a group message in iOS and have found different posts regarding the steps but when I open a group message and touch the I icon, there is no +Add User button to select from. Some have posted that this is because if there are other than iPhone users in a group message, iOS doesn't support adding additional users. Is this true? Even though I have the Send as SMS enabled?

Reply to Clarification on UIDesignRequiresCompatibility Key and Liquid Glass Adoption
Here's what we said in WWDC25 Platforms State of the Union: As you evaluate your app's UI and the time you need to adopt the new design, we're providing an option to continue to use your app's current design with Xcode 26. We intend this option to be removed in the next major release. — Ed Ford,  DTS Engineer
