Hello everyone,
I developed an iOS mobile application that allows users to download videos from platforms other than YouTube. However, Apple rejected my app due to Guideline 5.2.3 - Legal - Intellectual Property - Audio/Video Downloading.
Some apps also offer similar features. So, how were these apps published?
If anyone has a similar experience or knowledge about this, could you please help?
Thank you!

I am getting the following error while saving data to CoreData. my model has the dictionary property. I created NSSecureCoding and NSSecureUnarchiveFromDataTransformer classes. please check if i can encode my model correctly. I couldn't understand what I am doing wrong ? The problem is not with Dictionary or Data properties. Why can't I save data to CoreData?
I know little English. Thank you for your understanding.

It is a very simple one page project. I will be glad if you check it out.

CoreData Save Function:

Which design pattern should I choose for SwiftUI?
SwiftUI introduced its own set of challenges in the system’s design, so the patterns we had for UIKit have to be re-designed from the ground up.
The completely new design of the data flow in SwiftUI coupled with native support of view-state bindings shrank the required setup code to the degree that Presenter becomes a goofy entity doing nothing useful.
I am getting the following error while saving data to CoreData. I made this project completely simple for you to review my project. There is Local json in the project. You can download and test my project.

how can I solve my problem like here or in a different way.
When I make the Binding variable generic, I want to access the image property in the Array.
I am trying to make it a Generi Array. I will take two different models in it and I want to reach the image property in the model. How can I do that ?
I use two different models in different page transitions. How can I make the array holding the model generic?
Model 1:
struct TrafficSignContainer: Codable, Hashable {
var trafficQuestions: [TrafficSign]?
}
enum TrafficSignSectionType: String, Codable, Hashable {
case A = "A"
case B = "B"
}
struct TrafficSign: Codable, Hashable {
var id: Int?
var image: String?
var sections: [TrafficSignSectionType.RawValue : String]?
var correct: String?
}
Model 2:
struct PoliceSignContainer: Codable, Hashable {
var policeQuestions: [PoliceSign]?
}
enum PoliceSignSectionType: String, Codable, Hashable {
case A = "A"
case B = "B"
case C = "C"
}
struct PoliceSign: Codable, Hashable {
var id: Int?
var image: String?
var sections: [PoliceSignSectionType.RawValue : String]?
var correct: String?
}
View:
struct QuestionCardViewd: View {
@EnvironmentObject var signQuestionProvider: SignQuestionProvider
@EnvironmentObject var optionConfigure: OptionConfigure
@Binding var questions: [T]
var body: some View {
VStack {
HStack {
Text("\(optionConfigure.step + 1) /")
.bold()
Text("\(optionConfigure.questionCount)")
}
.padding(5) .background(Color(UIColor.secondarySystemBackground))
.cornerRadius(10)
.offset(y: -25)
ZStack {
ForEach((questions.indices).reversed(), id: \.self) { index -> AnyView in
let relativeIndex = index - optionConfigure.step
switch relativeIndex {
case 0...2:
return AnyView(
ImageCard(image: .constant("\(questions[index].image ?? "p1")")) **//-> here **
.offset(y: CGFloat(relativeIndex * -35))
.opacity(2.5 - Double(relativeIndex))
.scaleEffect(1 - CGFloat(relativeIndex) * 0.1)
)
default:
return AnyView(EmptyView())
}
}
}
.animation(.spring())
OptionView()
}
.onDisappear {
optionConfigure.step = 0
optionConfigure.selected = ""
}
}
}
When a wrong option is selected, I want to show the wrong option in red and then the correct option in green automatically. But I couldn't do the algorithm for it. How can I do that ? I prepared a sample project about the structure I use. I couldn't show the correct option and the wrong option at the same time when only the wrong option was selected.

While the app was pre-ordered, there was a sale in Canada and I can see it in the Sales and Trends category. (June 13) However, yesterday there was a sale in Turkey, but I can't see it in the Sales and Trends category. Does it take long for Apple to update this list?
There was a sale from Turkey yesterday, but I can't see it. Why is that ?
And I can't select yesterday's date. There was a sale from Turkey yesterday. I can't see this.

I have a variable in Dictionary type. How can I change the data on the Section Function to Dictionary?
Stringdata in the Section function shows the same value in both variables? I have to separate these values. How can I do that ?

try session?.send(word, toPeers: pears, with: .reliable)
} catch {
print(error.localizedDescription)
}

After initially establishing a connection between both devices, I successfully show the same word on both devices.
After choosing, the variables der, die, das are replaced by the word.
I know the problem but I don't know how to fix it.
This is what I want to do. Showing the same word on both devices after the devices are paired. Checking the answers after the selection has been made on both devices. A small quiz contest.
I want to compare the answer from both devices. I don't know how to do this.
for example; Suppose the answer "das" is correct for the first word. The user will mark "das" on the first device, and the user will mark "der" on the second device. the first device will get +1 points, the second device will not get any points.
Here is the problem: I apply two different send operations to a single data.
