First things first:
When posting code to these forums, place three backticks ``` on the line before your code and three backticks ``` on the line after your code so that it will be formatted properly. You can also highlight an entire code block and click the </> button on the toolbar to wrap the block for you.
This makes it far easier to read and also makes it easier for other posters to copy/paste the code in order to test solutions and such.
class ContentViewModel: ObservableObject {
var x:ROSList
@Published var originalItems1 = x.List
var words: [String] {
Array(originalItems1. prefix (wordCount))
}
}
import Foundation
struct ROSList {
var List = [“well-nurished”, “Agitated”, “equal”, “thin”, “ones”, “the”, “misfits”, “the”, “rebels”, “the”, “troublemakers”, “the”, “round”, “pegs”, “in”, “the”, “square”, “holes”, “the”, “ones”, “who”, “see”, “things”, “differently”, “they’re”, “not”, “fond”, “of”, “rules”, “You”, “can”, “quote”, “them”, “disagree”, “with”, “them”, “glorify”, “or”, “vilify”, “them”, “but”, “the”, “only”, “thing”, “you”, “can’t”, “do”, “is”, “ignore”, “them”, “because”, “they”, “change”, “things”, “they”, “push”, “the”, “human”, “race”, “forward”, “and”, “while”, “some”, “may”, “see”, “them”, “as”, “the”, “crazy”, “ones”, “we”, “see”, “genius”, “because”, “the”, “ones”, “who”, “are”, “crazy”, “enough”, “to”, “think”, “that”, “they”, “can”, “change”, “the”, “world”, “are”, “the”, “ones”, “who”, “do”]
}
Much nicer, even with the array trailing off screen (which can be fixed by putting in some linebreaks).
Now, to your problems…
- Error “Cannot use instance member ‘x’ within property initializer; property initializers run before ‘self’ is available”
This is because of these two lines:
var x:ROSList
@Published var originalItems1 = x.List
You are trying to initialize originalItems1 using a property of your class. That won’t work. All of your class properties have to be initialized before you can use the class, and x has not been initialized yet. Even if you add code to initialize x, though, it still won’t work because you can’t use the value of x until originalItems1 has been initialized. It’s a chicken and egg situation.
- Error “Class ‘ContentViewModel’ has no initializers”
Every property has to be initialized before a class (or struct) is ready to use. To give everything a value, you either have to assign one in an initializer or give the property a default value. In your code, x isn’t given a default value so it would need to be initialized in an init method. But, as the error is telling you, you have no init method(s).
Here’s how I would solve your dilemma…
struct ROSList {
static let list = [...] //fill in with your list items
}
class ContentViewModel: ObservableObject {
//leaving out everything else to make this example smaller
@Published var originalItems1: [String] = ROSList.list
}
Doing it this way means originalItems1 doesn’t depend on x being initialized in order to get its initial value. Instead, it relies on a static property of the ROSList struct to get its value.
Of course, this may or may not work for your larger project since I have no idea what you are doing elsewhere in your code, but hopefully it provides some guidance.
