Swift 6

I'm continuing with the migration towards Swift 6. Within one of our libraries, I want to check whether a parameter object: Any? confirms to Sendable. I tried the most obvious one: if let sendable = object as? Sendable { } But that results into the compiler error Marker protocol 'Sendable' cannot be used in a conditional cast. Is there an other way to do this?

I have a simple wrapper class around WCSession to allow for easier unit testing. I'm trying to update it to Swift 6 concurrency standards, but running into some issues. One of them is in the sendMessage function (docs here It takes [String: Any] as a param, and returns them as the reply. Here's my code that calls this: @discardableResult public func sendMessage(_ message: [String: Any]) async throws -> [String: Any] { return try await withCheckedThrowingContinuation { (continuation: CheckedContinuation<[String: Any], Error>) in wcSession.sendMessage(message) { response in continuation.resume(returning: response) // ERROR HERE } errorHandler: { error in continuation.resume(throwing: error) } } } However, I get this error: Sending 'response' risks causing data races; this is an error in the Swift 6 language mode Which I think is because Any is not Sendable. I tried casting [String: Any] to [String: any Sendable] but then it says: Conditional cast from '[String : Any]' to '[String : an

This is the complete Playground code: import MapKit import SwiftUI import PlaygroundSupport struct AddressSearchView: View { @State private var region = MKCoordinateRegion( center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194), span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01) ) var body: some View { VStack { Map(position: .constant(MapCameraPosition.region(region))) { } .frame(height: 300) } } } struct AddressSearchView_Previews: PreviewProvider { static var previews: some View { AddressSearchView() } } PlaygroundPage.current.setLiveView(AddressSearchView()) When I try to run this I get this in the debug console: error: Couldn't look up symbols: protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witness table for _MapKit_SwiftUI.EmptyMapContent : _MapKit_SwiftUI.MapContent in _MapKit_SwiftUI protocol witne

Xcode 8 beta 6.I have the following code. The only difference between 1, 2, 3, 4 and 5 is what is in the 'metrics' parameter.let a = 20 // 1: This compiles. _ = NSLayoutConstraint.constraints(withVisualFormat: |[v1(a)]|, metrics: [a: 20], views: [v1: v1]) // 2: This fails with Cannot convert value of type 'Int' to expected dictionary value type 'NSNumber'. _ = NSLayoutConstraint.constraints(withVisualFormat: |[v1(a)]|, metrics: [a: a], views: [v1: v1]) let met = [a: a] // 3: This fails with Cannot convert value of type '[String: Int]' to expected argument type '[String: NSNumber]?'. _ = NSLayoutConstraint.constraints(withVisualFormat: |[v1(a)]|, metrics: met, views: [v1: v1]) // 4: This compiles. _ = NSLayoutConstraint.constraints(withVisualFormat: |[v1(a)]|, metrics: met as [String: NSNumber]?, views: [v1: v1]) // 5: This fails with Cannot convert value of type 'Int' to expected dictionary value type 'NSNumber'. _ = NSLayoutConstraint.constraints(withVisualFormat: |[v1(a)]|, metrics: [a: a] as [Stri

Trying to migrate to Swift 6. However getting this error when using SwiftUI StoreKit purchase environment. Sending main actor-isolated value of type 'PurchaseAction' with later accesses to nonisolated context risks causing data races @Environment(.purchase) private var purchase let result = try await purchase(product)

I'm using this piece of code to access a url with beta 1 let config = NSURLSessionConfiguration.defaultSessionConfiguration() let userPasswordString = hroman:javierA17 let userPasswordData = userPasswordString.dataUsingEncoding(NSUTF8StringEncoding) let base64EncodedCredential = userPasswordData!.base64EncodedStringWithOptions(nil) let authString = Basic (base64EncodedCredential) config.HTTPAdditionalHeaders = [Authorization : authString] let session = NSURLSession(configuration: config) var running = false let url = NSURL(string: http:/ let task = session.dataTaskWithURL(url!) { (let data, let response, let error) in if let httpResponse = response as? NSHTTPURLResponse { let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding) print(dataString) } running = false } running = true task.resume() while running { print(waiting...) sleep(1) }I changed a few things and it doesn't work let config = NSURLSessionConfiguration.defaultSessionConfiguration() let userPasswordString = hroman:javierA17 let use

I creat a custom framework. In the framework, I define a protocol and a class. The class realize the protocol, and in my application create a class inheritance that class in the framework. Run it ,The console output not find the protocol`s methodxcode 8 bata 5 have no the problem.

Is there any chance to release IOS 15 to iPhone 6 and 6 Plus? Because of it, we cannot install Microsoft Teams. It support more than 14 IOS. Can you release IOS 15 to iPhone 6 and 6+?

Running into this new issue in beta 3. All of our immutable model attributes are now triggering swift compiler error from the title (tied to swift 6 - warning in swift 5). Neither warning or error show up on previous builds. Anyone else running into this? Hopefully not a limitation on swiftData that attributes must be mutable? filed as: FB14379932 (new in Xcode 16 beta3: cannot expand accessors on variable declared with 'let' in SwiftData Models)
