I've run into this problem before but can't resolve this time.I've downloaded researchKit using git clone -b stable https://github.com/ResearchKit/ResearchKit.gitBuilt it and added it to the ORKCatalog sample. On building that sample I get the error "appledoc is required for building ResearchKit's documentation. See http://appledoc.gentlebytes.com"Any suggestions? Thanks

HI I've updated my fortran program and I'm trying to get through the notarizing process. I created a pkg with >pkgbuild ... I signed the package with >productsign ... I created an application password for notarytool I created store credentials with >xcrun notarytool store-credentials ... Received: Success. Credentials validated. Credentials saved to Keychain. Requested notarization with >xcrun notarytool submit ... Submission ID received Successfully uploaded file Current status: Waiting.... after a minute or two this changed to Current status: Invalid... Could this because the notarizing system doesn't understand Fortran executables or is there something else I've done incorrectly? I have a submission id, is there a way to get more information. Thanks, David

I was able have an app transferred from another AppleID to my personal AppleID. The transfer seemed to go OK (https://help.apple.com/app-store-connect/#/deved688524f) however there seems to be a problem now when I try to update the app. I've changed 'ownership' where I can see but when I uploaded the new version, the old bundleID no longer matches my new AppleID format. Do I keep the old bundleID? I'd prefer not delete and recreate the app. That was why I chose the transfer method. Any suggestions, thanks,. David

I installed Sonoma beta on my personal laptop and I find it set-up with a profile. This profile seems to prevent logging into iCloud when started up FreeForm. A bug or something I can fix? Thanks, David

Is it possible to remove/reset GmeCenter scores for my game app? I'd like to remove all scores so new users can start to compete. Is this possible? The games are educationally based and I'fd like to reset score for a new class.

In a tvOS app I have two buttons and would like to determine which one has focus when selected. Using func pressesBegan works for nw. override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) { guard let selected = UIScreen.main.focusedItem else { return } Xcode tells me that focusedItem is deprecated and I should use -[UIWindowScene focusSystem].focusedItem instead. Any suggestions on a code snippet that could be used. Thanks

What is the best way to demonstrate or create 2D video to demonstrate an immersive video app? So far I've shared the AVP to my desktop Mac and screen captured the resulting view. Rather shaky at times. With visionOS 2.0 beta (2) is there a better way? Thanks, David

The actual error: pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (DeveloperID)”. I'm trying to sign a program written with gfortran. The steps worked the last time (Mar 23) I built this code. The steps to error: a) xcrun notarytool store-credentials --apple-id "xxx" --team-id "yyy" Giving Profile Name zzz and App-specific password b) codesign --force --timestamp --options=runtime -s "Developer ID Application: My Name (yyy)" AppName c) pkgbuild --root ROOT --identifier org.aaa.bbb --version "1.1.1" --sign "Developer ID installer: My Name (yyy)" AppName.pkg ROOT contains the package contents At this point I get the error pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (yyy)” Are there steps that have changed. Any suggestions? Thanks, David

What do I need to do with my webpages to enable Safari AI summary functionality? Thanks, David

I have a TVML style app on the app store that no longer seems to work. I'm working on converting it to SwiftUI after seeing the WWDC video "Migrate your TVML app to SwiftUI". I've got most of the code working up until I'm trying to display video from a remote source (my website). It looks like the network connection is blocked, maybe. On a macOS app I see a App Sandbox capabilities that include Network access. I don't see that option for the tvOS app. Am I missing something or is it not needed, and I should look elsewhere? Thanks, David

I have used mlx_lm.lora to fine tune a mistral-7b-v0.3-4bit model with my data. I fused the mistral model with my adapters and upload the fused model to my directory on huggingface. I was able to use mlx_lm.generate to use the fused model in Terminal. However, I don't know how to load the model in Swift. I've used Imports import SwiftUI import MLX import MLXLMCommon import MLXLLM let modelFactory = LLMModelFactory.shared let configuration = ModelConfiguration( id: "pharmpk/pk-mistral-7b-v0.3-4bit" ) // Load the model off the main actor, then assign on the main actor let loaded = try await modelFactory.loadContainer(configuration: configuration) { progress in print("Downloading progress: \(progress.fractionCompleted * 100)%") } await MainActor.run { self.model = loaded } I'm getting an error runModel error: downloadError("A server with the specified hostname could not be found.") Any suggestions? Thanks, David PS, I can load the model from the app bundle // directory: Bundle.main.resourceURL! but it's too big to upload for Testflight

I'm downloading a fine-tuned model from HuggingFace which is then cached on my Mac when the app first starts. However, I wanted to test adding a progress bar to show the download progress. To test this I need to delete the cached model. From what I've seen online this is cached at /Users/userName/.cache/huggingface/hub However, if I delete the files from here, using Terminal, the app still seems to be able to access the model. Is the model cached somewhere else? On my iPhone it seems deleting the app also deletes the cached model (app data) so that is useful.

I'm just starting with Immersive Spaces. I am able to view one immersive space but when I tried to open a different one (after restarting the app) I got an error that only one space can be opened (at a time). I added before the openImmersiveSpace call. Now I see a warning shown in the post title. That is Unable to dismiss an Immersive Space since none is opened The app still works but it would be nice to detect when a Space is open so I could check and only close the 'old' space when present before opening the 'new' space. Any suggestions? Thanks. David

I'm developing a tutorial style tvOS app with multiple videos. The examples I've seen so far deal with only one video. Defining the player and source(url) before body view let avPlayer = AVPlayer(url: URL(string: "https://domain.com/.../.../video.mp4")!)) and then in the body view the video is displayed VideoPlayer(player: avPlayer) This allows options such as stop/start etc. When I try something similar with a video title passed into this view I can't define the player with this title variable. var vTitle: String var avPlayer = AVPlayer(url: URL(string: "https://domain.com/.../.../" + vTitle + ".mp4"")!)) var body: some View { I het an error that vTitle can't be used in the url above the body view. Any thoughts or suggestions? Thanks

I'm importing a csv file of 299 rows and creating a subset by filtering on one column value (24 rows). I want to Chart just the filtered values. However, when I print one column I get values from the original dataFrame. Any suggestions? Thanks, David The code: import SwiftUI import Charts import TabularData struct DataPoint: Identifiable { var id = UUID() // This makes it conform to Identifiable var date: Date var value: Double } struct ContentView: View { @State private var dataPoints: [DataPoint] = [] var body: some View { Text("Hello") Chart { ForEach(dataPoints) { dataPoint in PointMark( x: .value("Date", dataPoint.date), y: .value("Value", dataPoint.value) ) } } .frame(height: 300) .padding() .onAppear(perform: loadData) } func loadData() { print("In Loading Data") // Load the CSV file if let url = Bundle.main.url(forResource: "observations", withExtension: "csv") { do { let options = CSVReadingOptions(hasHeaderRow: true, delimiter: ",") var data0 = try DataFrame(contentsOfCSVFile: url, options: options) let formattingOptions = FormattingOptions( maximumLineWidth: 200, maximumCellWidth: 15, maximumRowCount: 30 ) // print(data0.description(options: formattingOptions)) print("Number of Columns: \(data0.columns.count)") let columnsSet = ["plant_id", "date", "plot", "plantNumber", "plantCount"] data0 = try DataFrame(contentsOfCSVFile:url, columns: columnsSet, options: options) print("Number of Columns (after columnsSet): \(data0.columns.count)") print("Printing data0") print(data0.description(options: formattingOptions)) let data = data0.filter { $0["plant_id"] as?
