I will close this thread I have a better idea. SOLVED does not mean closing. Please share your solution and mark it as SOLVED.

You should better add another variable unusedQuestions. When you pick a new question from unusedQuestions, remove it.

SOLVED: Was a matter off hierarchy and wasn't putting the change view inside the alert  When your issue is SOLVED, please mark the reply (in this case, of your own) as the solution.

here it is,  Where? Or what is it? I first wrote Please show your code instantiating Main. Your newly shown code does not contain anything about Main. I then wrote you need to call environmentObject(_:) somewhere in your code. But I cannot find environmentObject anywhere?

u are just asking interesting question, but no any solution, I am asking questions not for my interest, but for finding solutions. And at last, you have shown a code which could be very helpful to find a solution. (Sorry, but may not be enough.) At a glance, I cannot find what's wrong and take some more time to explore.

I tried your code and I could not reproduce the error No ObservableObject. I needed to guess many parts you have not shown, so that may be causing the difference. Once, again. Please show your code instantiating Main. (Please do not omit the declaration header, and please include all relevant codes.)

I show all code, u are not intend to solve problems. Far from all code. I get an error Cannot find 'msgs' in scope with your Main. If you really want to solve your issue, please show enough info to solve it.

here it is I gave some code about it: Sorry, but you tend to omit the first line of codes. What sort of line comes before var id : Int And again, Please show your code instantiating Main. In other words, please show all the code including Main().

Thanks for showing additional codes. But what relation are there between chatTopview or chatCell and already shown codes? In your actual project, chatTopview is the actual Main? Or something else? I cannot find any lines including Main(). Please understand, we readers do not have any info about what you want to do or how your project is made, Please, please show enough info, if you really want to collaborate with readers to solve your issue.

Seems your showing code will continue. Please tell us when done. And please care about the first line of each code.

One way, define an ObservableObject and share the instance of it among the views.

when I click the chatcell, it throw error I really appreciate your effort, but I cannot find any parts using chatCell, so I cannot test click the chatcell. And when I click cellView in Main, no errors thrown. It seems the problem exists in somewhere still not shown yet.

This project writen in SwiftUI 1.0, I want to convert to swiftUI 2.0 . it say ( It might be helpful under some different context. But as for now, without enough code to reproduce the issue, I can say just there is something wrong in the hidden parts of your code.

seems to be bug It may be a bug of SwiftUI, or it may be a bug of your code. You have not shown enough info to judge.

I shown all Not true!!! Where is the tab view you mentioned? Where is ConentView? Chat? msgdataType? msgTail? Rounded? Why is there no code using chatCell?!?!?! Say shown all after you have shown all!!!!!
