`try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord)
try AVAudioSession.sharedInstance().overrideOutputAudioPort(.speaker)
That doesn't work. The background music still comes from the headphones.

this my code:

iOS15
This is working correctly in all iOS 14.x, but on iOS 15.0 seems broken.
Thanks a lot for any tip or help.

I am getting an error:
One or more of the following type_info's has hidden visibility or is defined in more than one translation unit. They should all have public visibility. N10__cxxabiv116__shim_type_infoE, id,
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'The fetch request's entity 0x28360c160 'CustomModel' appears to be from a different NSManagedObjectModel than this context's'
Here is my subclass:
import Foundation
import CoreData
public class CustomModel: NSManagedObject, Identifiable {
@NSManaged public var name: String?
@NSManaged public var select: Int
}
extension CustomModel {
static func allCustomModelFetchRequest() -> NSFetchRequest<CustomModel> {
let request: NSFetchRequest<CustomModel> = CustomModel.fetchRequest() as! NSFetchRequest<CustomModel>
request.sortDescriptors = [NSSortDescriptor(key: "CustomModel", ascending: true)]
return request
}
static func queryCustom(name:String) -> NSFetchRequest<CustomModel> {
let request: NSFetchRequest<CustomModel> = CustomModel.fetchRequest() as! NSFetchRequest<CustomModel>
request.predicate = NSPredicate(format: "name == %@",name)
request.sortDescriptors = [NSSortDescriptor(key: "CustomModel", ascending: true)]
return request
}
}
let results = CustomModel.queryCustom(name: name)
do {
let results = try viewContext.fetch(results)
} catch let err as NSError {
}
Here is my entire debug window:
