CoreData and Group By
Hi Folks, Sorry I am sure this has been asked before - Beginner level programmer trying to get my head round something I am sure is simple. I know coredata is not a Relational database but please go easy!! I have data my app is storing as people respond to the 'game' a 'session' guid (runNumber) , and if they hit the correct button or not (correctAnswer). I want to group the responses by the guid and sum the 'correct' answers. I think I am pulling the data correctly: @Environment(.managedObjectContext) private var viewContext @FetchRequest( entity: CoreScore.entity(), sortDescriptors: [ NSSortDescriptor(keyPath: CoreScore.runNumber, ascending: false) ] ) var corescores: FetchedResults But my view List(corescores, id: .self) { corescore in Text(corescore.runNumber ?? Unknown) Text(corescore.correctAnswer ?? Unknown) } Shows all the individual responses... How do I group them by runNumber?

Wednesday Security Lab Notes
Question:In the session yesterday, it was mentioned that Gatekeeper's app relocation moved the app on an unsigned disk image to a randomized place on the filesystem. How does this work?Answer:When the app with the unsigned dependencies is launched, Gatekeeper makes a synthetic instance of the app at a randomized location elsewhere in the filesystem. The synthesized instance of the app is what is actually being launched.The synthesized instance is by itself in this new location, so it's unable to access the unsigned code / library / script, etc when it launches.The synthesized instance is not a copy of the app. Overall behavior is similar to nullfs on BSD, or using bind mounts on Linux.Question:Are there any new features in System Integrity Protection on Sierra, or will the functionality be the same as in El Capitan? If there are new features, what are they?Answer:Same functionality as in El Capitan.Question:Are there new restrictions in System Integrity Protection on Sierra, or do the restrictions currently m

MinuteWeather summary property returns empty string
I've been unable to get MinuteWeather to return anything for the summary property -- it used to return a nil value which was fixed in a previous beta, but now it always returns an empty string. The rest of the MinuteWeather data returns as expected. Example call: let latitude = 37.323 let longitude = -122.032 Task { let weatherData = WeatherData.shared let minutely = await weatherData.minutelyForecast(for: CLLocation(latitude: latitude, longitude: longitude)) guard let minutelyWeather = minutely else { print(WeatherKit minutely data unavailable) return } print(minutelyWeather.summary) // This returns } WeatherData class: class WeatherData: NSObject { static let shared = WeatherData() private let service = WeatherService.shared func minutelyForecast(for location: CLLocation) async -> WeatherKit.Forecast? { let minuteWeather = await Task.detached(priority: .userInitiated) { let forecast = try? await self.service.weather(for: location, including: .minute) return forecast }.value return minuteWeather

Cannot remove testing group from build/Groups auto adding to build
Hi, I would like to rollout our builds to a subset of our internal testers (the devs) before we roll it out to the rest (QA, product managers). After submitting the compliance on a build, both of my internal testing groups are automatically added to the build. I thought I would get to choose which group at add myself. To make matters worse, there doesn't appear to be any way to remove a testing group from a build, despite what the documentation says: As you can see, my pointer is over the group, but no Delete button exists Help! -Ethan

Switching subscription groups
I have an app where fans can subscribe to multiple content creators and this is implemented using a sub group for each creator. I want to add a new all access subscription that gets them access to everything. We are treating this as an upgrade from the individual sub. Is there a way to cancel (or swap) the individual sub when they subscribe to the bundled sub? I know within a sub group it is possible to go between sub levels, but not sure about across sub groups.

Group Apps
Since I have upgraded to IOS 14.2 on my iphone7. On several occasions I have found that I am unable to open my apps that I have grouped together. When I touch the screen the apps acknowledge that I selected it but it does nothing after that.
