Hi all,

I am getting goin on building the habit tracker app and I am running into snafu's right out of the gate.

I am getting the error "'ModifyHabitView' initializer is inaccessible due to 'private' protection level" in both files pasted below. I'm attaching images, but in ContentView it's on the line with ModifyHabitView(habits: self.habits). And in ModifyHabitView it's down in the preview struct. I'm attaching screen shots and a link to the repo as well.

Can someone tell me why this error is occurring?

Hi,

It might not help at all but if you change the line in Activities class from @Published var activities =[SingleActivity]() to @Published var activities: [SingleActivity] ?

Hi @Tiberiu27,

Thanks for looking at my problem and providing a suggestion. I tried your suggestion and the compiler immediately showed an error on that line asking me to change it back to @Published var activities =[SingleActivity]()

Let me know if you have any other ideas.

Hi,

So, I downloaded the code and I fooled around for a bit and then I saw it.

In the ModifyHabitView changed

  @State private var title: String
  @State private var description: String

to this:

  @State private var title = ""
  @State private var description = ""

It seems it works for now :)

That was it!

I wonder why the other way doesnt work...🤔

Not quite sure, let me know when you find out :D
