Have a look at the following article: https://www.massicotte.org/isolation-intuition about Swift Isolation Intuition. Perhaps it will help you understand where Swift runs your code.

Have a look at the Perception package from the point.free guys. It is a backport of the Observation tools to earlier OSs: https://github.com/pointfreeco/swift-perception

This was finally fixed in the release candidate of 17.4. Thank you!

I think, the only way to do this is to create a new (empty) .swiftpm package and copy the files/coded across.

You have to keep a reference to the Cancellable returned by sink: import Combine class MyModel: ObservableObject { @Published var selection = FamilyActivitySelection() var cancellables = Set<AnyCancellable>() init() { $selection.sink { newSelection in print(newSelection) }.store(in: &cancellables) } }

This works as intended. Try if using the new Observation helps in your case.

Unfortunately plane detection is still unsupported in the simulator. There is already a thread about this problem.

I came up with the following solution to dynamically load Assets from Data after reading a thread on StackOverflow : import Foundation import AVFoundation #if os(macOS) import AppKit #else import UIKit #endif // Don't forget to set the File Type field in the asset catalog to the correct UTI string: com.apple.quicktime-movie extension NSDataAsset:AVAssetResourceLoaderDelegate{ @objc public func resourceLoader(_ resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool { if let infoRequest = loadingRequest.contentInformationRequest{ infoRequest.isEntireLengthAvailableOnDemand = true infoRequest.contentType = typeIdentifier infoRequest.contentLength = Int64(data.count) infoRequest.isByteRangeAccessSupported = true #if DEBUG print(infoRequest) #endif } if let dataRequest = loadingRequest.dataRequest{ #if DEBUG print(dataRequest) #endif dataRequest.respond(with: data.subdata(in:Int(dataRequest.requestedOffset) ..< Int(dataRequest.requestedOffset) + dataRequest.requestedLength)) loadingRequest.finishLoading() return true } return false } } extension AVURLAsset{ public convenience init?(_ dataAsset:NSDataAsset){ guard let name = dataAsset.name.addingPercentEncoding(withAllowedCharacters: .urlPathAllowed), let url = URL(string:"NSDataAsset://\(name))") else {return nil} self.init(url:url) // not really used! self.resourceLoader.setDelegate(dataAsset, queue: .main) // Retain the weak delegate for the lifetime of AVURLAsset objc_setAssociatedObject(self, "AVURLAsset+NSDataAsset", dataAsset, .OBJC_ASSOCIATION_RETAIN) } }

On device your App runs in the sandbox, in the simulator there are no file access restrictions: You have to request access to files in certain directories using code similar to this: _ = url.startAccessingSecurityScopedResource() // your file access here url.stopAccessingSecurityScopedResource() https://developer.apple.com/documentation/foundation/nsurl/1417051-startaccessingsecurityscopedreso

Because the formatting of your message and code is broken I can't be sure. Does this even compile? At least it should say id:\.self

Finally(!) four weeks later the necessary update was published: https://apps.apple.com/de/app/swift-playgrounds/id908519492

This seems to be a missing translation in iOS. It started in iOS 16, was fixed in iOS 17 betas and now unfortunately returned for 17.0. You can add a Localizable.strings file to your project containing the following text: "Back" = "Zurück";

iOS Version expired already a week ago though.

You have to mark your struct Dummy and var name as public.

The whole "transferable" API seems pretty strange. Only some cases seem to work and no progress since last year.
