but 1 is default so this seemed unnecessary. You may be mistaking something. If you want to use stepper correctly, you need to set value. My aim with the VC is to change the value of the ration array in the model, the VC only shows the number listed in the model Can't you see what is given to onValueChanged? Please try before saying something based on wrong assumptions.

    and feedProduct is defined here in the for loop: It's feedProduct, not FeedProduct.

Thanks for adding code. But with all your shown code, Xcode generates some errors: Cannot find 'FeedProduct' in scope Cannot find 'FeedProduct' in scope Cannot find 'feedStack' in scope Have your created a brand-new project to check what are needed?

Let me know if more code is needed, Please show everything needed to compile your code.

The text editor is expected to update the value of instances of the EnvironmentObject once any editing happens. it applies as soon as any change happens, which is not desired Seems your description is inconsistent. Please specify when do you want to save clearly.

I want to type something up and make appear somewhere else but I also want it to be saved with SceneStorage too. You can use textfield instead of Text.

If those projects are developed in the same organization, you should use the same identifier.

I trying to figure out how to two variables to a textfield and telling a other guy what textfield I meant by. Sorry, but it does not explain why you need two variables. You can use textfield instead of Text.

a textfield I'm talking about is one you type things in. So what? Can you explain?

According to the CIFilter initializer, it is recommended to provide this option.   Thanks. I was missing that part.

This line is causing the issue: let storeView = storeViewController() (In Swift, type names should start with Capital letters.) You should not create a new instance of a view controller using init(). You need to access the right instance of storeViewController without creating a new one. To find how to fix, you need to clarify the relationship (transition) between storeViewController and liveViewController.

Are you sure kCGImageSourceTypeIdentifierHint is the right key for your purpose? The doc of kCGImageSourceTypeIdentifierHint says This key can be provided in the options dictionary when you create a CGImageSource object, no mention about CIFilter. At least, the key needs to be of type CIRAWFilterOption, not String. let sourceTypeIdentifierHint = CIRAWFilterOption(rawValue: kCGImageSourceTypeIdentifierHint as String) let rfo: [CIRAWFilterOption: Any] = [ sourceTypeIdentifierHint : "com.sony.raw-image" ]

Is that means I can declare import inside class's body code block?? NO.

Are you talking about the buttons of the navigationBarItems? Or the buttons of each row of the List?

Can you be more specific? What is Variable to a text field? If you mean text parameter of a text field, there are no ways to have two. Why don't you use two text fields?
