Adiitionally: Don't confuse running the body with "view creation". Running the body does not really show anything yet.

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.
