SwiftUI List performance

2. 3 Performance: Accurate Metadata Guideline 2.3.1 - Performance We discovered that your app contains obfuscated code, selector mangling, or features meant to subvert the App Review process by changing this app's concept after approval to the App Store.My previous version of app got approved.Current version of app minor UI/UX changed and i received above app rejection reason from apple.Any suggestion.

My app currently uses the iCloud to bring down data for a list using swift how can I use SwiftUI to bring that data down and populate a list ?

I have been working on a SwiftUI app that targets both iOS/iPhones and iPadOS/iPads and have found an issue with a the List contents being completely visible (i.e. not blurred) under the Navigation Title as shown below. It seems to only occur if the detail view is a TabView, and even then it still doesn't occur every time. The issue only occurs on iPads. Everything seems work fine on iPhones running iOS 15. A recreation can be found in the following code: import SwiftUI struct TestMainList: View { var body: some View { NavigationView { ScrollView { VStack { ForEach(1..<21) { NavigationLink(Detail ($0), destination: TestDetailTabView(name: Detail ($0))) .padding() Divider() } NavigationLink(destination: EmptyView()) { EmptyView() } } } .edgesIgnoringSafeArea([.bottom]) .navigationTitle(Text(List)) EmptyDetailView() } } } struct EmptyDetailView: View { var body: some View { Text(Select a detail item to view) } } struct TestDetailTabView: View { var name: String var body: s

Hi, I have an app, (match 3 game) sinse 5-6 year on the store.. I recently perform 2 changes... Improve GUI to support iphoneX / new ipad resolution and add button (reward video to receive free game items) but apple reject my apps with this reason...(Guideline 2.3.1 - Performance) and not send more details... Is beacuse is a paid app and cannot have reward video on it ? ThanksCarl

Suppose I have an array of strings, and I want to find the index of a given string in that array. I'm wondering whether there will be much of a performance difference between these two functions:func indexOfName(name: String) -> Int? { for (index, element) in names.enumerate() { if element == name { return index } } return nil }func indexOfName(name: String) -> Int? { return names.enumerate().filter { $0.element == name }.first?.index }Or is the difference between them simply one of notation?

HI , I am going through the Swift UI tutorial “ Landmarks” app. Under building the landmarks list view section https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation I found that the instruction to add Identifiable option to the Landmark structure is not given. Due to this the preview of the LandmarkList fails to load in the SwiftUI canvas. The error shows “ cannot parse landmakData.json. Please correct the documentation.

I am using OpenGL ES 3 on a CADisplayLink. Everything is working, but I noticed that the frame rate degrades after a device has been used for a while (using my app or other apps). Rebooting the device restores the full performance.I am aware that advising users to reboot is a violation of the Human Interface Guidelines so if performance drops below a threshold the app isn't suppose to prompt the user to restart.Is there anything I can do to ensure the user is experiencing maximum performance? The difference between full performance and the degraded performance I am seeing is rather stark - somewhere around half the performance.It seems this affect has been observed by others, please see: http://stackoverflow.com/questions/12239576/ios-opengl-es-1-1-jerky-animation-using-cadisplaylink-reboot-fixes-for-a-whileThe referenced Stack Overflow was answered by the OP as to why their logged numbers didn't make sense, but nothing was done to address the lower performance oth
