Reply to Command line standalone app - run on other Macs

I think the first thing to do would be to figure out why you are typing both /usr and /user. If that is really output from Xcode, then you've got a royal mess on your hands. If you are re-typing, can you include Xcode's exact output?If this is a lab environment, then it probably makes more sense to just install the dependencies in the lab. It is a bit of a hassle, but you would been done by now.

Issue with iOS group entitlements being recognized

I am making an iOS step counting app and I have included a widget in the design. I would like to get the widget to pull data from the main app to display step count etc so I created a bundle id for the widget and have been trying to use a group id to link them together. The group capabilities for both seem to be set up/enabled properly with the same App Groups id, but I've been getting an error in xcode which says, 'Provisioning Profile: BUNDLE_ID doesn't include the com.apple.developer.security.application-groups entitlement.' Try Again But the identifiers do have the App Group id enabled. I have tried automatic signing, manual signing with generated profiles, unchecking and rechecking auto-signing, removing and re-adding the group capability. Creating a new bundle id from scratch, creating a new group id from scratch. Always I get the error. I've really pulled my hair out troubleshooting this and would appreciate support. I'm happy to answer an

Reply to Using .glassEffect in Charts

Generally speaking, Liquid Glass is not a part of Swift Charts. For recommendations about using Liquid Glass I suggest reviewing the WWDC25 sessions about Liquid Glass. They discuss many considerations about how and where to employ the new Liquid Glass GUI features.

Reply to iOS 15 - "Keep..." button in provisional user notifications doesn't save the settings

I am also seeing the same issue whereas tapping Keep does not ask the user if they want them delivered prominently or quietly. It does have a button asking for showing them in a summary - but I as a user do not have summaries turned on. Tapping the summary button does not enable summaries either. I am trying to convince people we should switch over of using provisional notifications to be better iOS clients, but this issue will never get past the product department's scrutiny.

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?

Reply to The Liquid glass blur effect does not show over the UITabBar as content scrolls underneath.

The blur effect you see is actually the scroll edge effect from UIScrollView. By default, UITabBarController will configure scroll views in its descendant hierarchy with scroll edge effects. If you are using a custom tab bar, you can configure one yourself using UIScrollEdgeContainerInteraction. To learn more, you can also watch Build a UIKit app with the new design from WWDC25.

Somehow this fixes it: (blur.contentView as! UIView).addSubview(vib) (vib.contentView as! UIView).addSubview(lab)
