Thanks so much Quinn for this very precise answer (as usual!). The security reason is a very convincing one. I’ll wait for FSKit. And run in user space (it would just be for my personal use), limiting myself to read only.

Just to understand: why do you need static table view ? I've found that very old thread but you may find useful information there: https://stackoverflow.com/questions/22364230/static-table-view-outside-uitableviewcontroller Hope that helps.

So, when you ask a question, please provide complete information. That will avoid we loose time in guessing. Have a good day.

I tested in playground in an init, and no crash: class OrderTest { struct Order { var order: Int } var nextOrder: Int? var allItems : [Order] = [] init() { nextOrder = self.allItems.map{$0.order}.max() print("nextOrder", nextOrder) if nextOrder == nil { nextOrder = 0 } print("nextOrder after test", nextOrder) nextOrder! += 1 // <--- Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value } } let orderTest = OrderTest() So problem is somewhere else. Could you show the class or structure where this init() is ? One way I could get it crash was by delaying the allocation of next order with a Dispatch: class OrderTest { struct Order { var order: Int } var nextOrder: Int? var allItems : [Order] = [] init() { nextOrder = self.allItems.map{$0.order}.max() if nextOrder == nil { DispatchQueue.main.async(execute: { // <<-- WITH THIS, IT CRASHES self.nextOrder = 0 }) } nextOrder! += 1 // <--- Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value } } Did you show the exact and complete init() ?

It may be because you do it in the init. I propose to add a return. init() { nextOrder = self.AllItems.map{$0.order}.max() if nextOrder == nil { nextOrder = 0 return // <<-- ADD THIS } nextOrder! += 1 // <--- Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value } or add an else: init() { nextOrder = self.AllItems.map{$0.order}.max() if nextOrder == nil { nextOrder = 0 } else { // <<-- ADD THIS nextOrder! += 1 // <--- Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value } }

Don't worry, no problem with your existing apps. Just needed to submit a new release. You can do it even when certificates have expired. But you can do it now, before it expires. I know at least 2 ways (I prefer the first): First go to Xcode > Settings > accounts select your account and there ask for new certificates if you see they will obsolete soon. that's it Second In Xcode project, select TARGETS In signing and capabilities, you will see the certificate is obsolete. Ask to sign again

Welcome to the forum Could you post a screenshot ?

It would help to see the code on which error is reported… And please tell about the context. Is it a SwiftUI app ? Is it a problem in Preview ? Or is it when you try to run on simulator ?

You don't show enough code (eg, ContentView) to find out what is the problem. Card is not ObservableObject. That may be the cause of the problem. Try to make it a class and ObservableObject. 2 more comments: why don't you use environmentObject for deck, instead of all the bindings ? in Xcode16, observable is much easier to use than ObservableObject. If needed, get details here: https://medium.com/@vladislavshkodich/remove-observableobject-from-your-swiftui-model-cb455e9572ef

I was looking for User definition. It is a Firebase class, should be this one: https://firebase.google.com/docs/reference/swift/firebaseauth/api/reference/Protocols/UserInfo.html I suppose error is here: let updatedUser = User( coder: <#NSCoder#>, id: userId, name: name, email: email, phoneNumber: phoneNumber, profilePictureURL: nil, bio: bio ) why do you include coder here ? And what does <#NSCoder#> mean ? Where did you get it ? I understand you have several init for User: either with coder public required convenience init?(coder: NSCoder) or direct declaration with all the properties. So, you'd better study carefully FireBaseAuth documentation.

It is difficult to guess the overall structure of your code. Is DotGenerator calling ContentView ? Did you look at the solution I proposed ?

That's not a good way to ask a question, just formulating the error in the title. Where do you get the error precisely in your code ? We cannot guess.

Welcome to the forum. Please show the complete code. How is User defined ? It seems you forgot a closing parenthesis, isn't it ?

You don't show how the view uses the result. That should help. I would do it with recursively calling iteration steps. In the View, as an action for a button, call simulation() This function is defined as func simulation() { let numberOfStep = 100000 // any very large number runSimulation(in: stopped.atStep..<numberOfStep) } The trick is that in runSimulation(), you call calls it recursively func runSimulation<T: Sequence>(in sequence: T) where T.Element == Int { // execute one step of the loop runSimulation(in: sequence.dropFirst()) // call recursively } stopped is a state var @State var stopped : (on: Bool, atStep: Int) = (on: false, atStep: 0) atStep is the value (loop index) at which you may have stopped with another button action in the view, which let's you resume where you stopped if you want with a resume button. Note that in your case, you could do it by chunks of 100 steps instead of individual steps, so the number of steps would be 1000 instead of 100000 for instance.
