My database has over 100k entries and anytime I access it either via @Query or a custom Fetch request it freezes my apps UI for 10+ second. My first question is anyone having performance issues with large data sets. If so how have you found to resolve it ? My next question is does swiftUI load the entire database into memory with the @Query. As I feel it is seeing as my app becomes very slow and partially unresponsive. lastly if I have 2 data models and 1 has a to many relationship to the other are both loaded into memory even though only @Query 1? consider datamodels model1 { var name : String @Relationship(deleteRule:.cascade) var lotsOfData :[LotsOfData] init.... } LotsOfData{ var element1 : String var element2 : String var element3 : String var element4 : String var element4 : String init …. } LotsOfData has 100K instances in the database. if I @Query into model1 because it references LotsOfData through A relationship is all that data all called / loaded ? thanks for the information

From the Internet I read that URLRequest sends an Accept-Encoding header by default. I also read that URLSession auto decompresses any data that’s returned compressed. However these are what the internet says. I go to the Apple docs and read the URLSession & URLRequest sections but I can’t find where does it say that it sends the Accept-Encoding headers by default or that it auto decompresses compressed data. I know it does the latter as I am able to parse compressed data and have to do nothing to decompress. Just tell me where this stuff is documented by Apple so I can read about it.

I use UIHostingController inside my UIViewController to present a SwiftUI View. I have a button in that view which I want to tap and dismiss the presented view. How do I dimiss SwiftUI views when presented in a UIHostingController...{ let vc = UIHostingController(rootView: SwiftUIView()) present(vc, animated: true, completion: nil) }struct SwiftUIView : View { var body: some View { CustomButton() } }struct CustomButton: View { var body: some View { Button(action: { self.buttonAction() }) { Text(buttonTitle) } } func buttonAction(){ //dismiss the SwiftUIView when this button pressed } }
