I’m testing sorted(by:) time consuming in iPhone 14 real device and found that sorting @Model types is x100 times more slower…. Why?

        Button("sort 50K [Int]"){
            var numbers = Array(0..<50_000).shuffled()
            let startTime = Date.now
            numbers.sort()
            print("Elapsed time to sort 50K Ints: (Date.now.timeIntervalSince(startTime))") // 0.06...
        }
        
        Button("sorted 50K [Int]"){
            let numbers = Array(0..<50_000).shuffled()
            let startTime = Date.now
            let sortedNumbers = numbers.sorted()
            print("Elapsed time to sorted 50K Ints: (Date.now.timeIntervalSince(startTime))")// 0.06...
        }
        
        Button("sorted 50K [NoPersistedItem]"){
            let items = Array(0..<50_000).shuffled().map{NoPersistedItem(value: $0)}
            let startTime = Date.now
            let sortedItems = items.sorted(by: {$0.value<$1.value})
            print("Elapsed time to sorted 50K Ints: (Date.now.timeIntervalSince(startTime))")// 0.06...
        }
        
        Button("sorted 50K [PersistedItems]"){
            let items: [Item] = Array(0..<50_000).shuffled().map{Item(value: $0)}
            let startTime = Date.now
            let sortedItems = items.sorted(by: {$0.value<$1.value})
            print("Elapsed time to sorted 50K Persisted Items: (Date.now.timeIntervalSince(startTime))")// 5.3...
        }

@Model
final class Item {
    var value: Int
    
    init(value: Int) {
        self.value = value
    }
}

struct NoPersistedValueType {
    let value: Int
}

class NoPersistedReferenceType {
    let value: Int
    init(value: Int) {
        self.value = value
    }
}

Real project:

@Model
final public class Item {
    @Relationship(deleteRule:.cascade) var entries: [Entry] = []
    @Transient
    var sortedEntries: [Entry] {
        entries
            .filter{!$0.escaped}
            .sorted(by: {$0.date<$1.date})
    }
    //...
}
