I've got a Graph class which is an UIView and I'm initializing it inside mainVC.swift
:
class MainVC : UIViewController{
let graph : Graph!
override func viewDidLoad(){
super.viewDidLoad()
let data_x : [Double] = [...]
let data_y : [Double] = [...]
...
graph = Graph(frame: CGRect(...), color: ..., xData: data_x, yData: data_y, darkMode: ...)
view.addSubview(graph)
...
}
Now I would like to access function inside instance of the class which I've created in MainVC in different class (to populate data in TableView).
var g : Graph = MainVC.graph
returns "Instance member graph cannot be used on type MainVC"
I've also tried using static variable but there was an error.
This is one of the way which i known check it out.
graph is a stored property is a constant or variable that is stored as part of an instance of a particular class.So you tried for accessing instance property not an instance of class.
In your class MainVC make variable as static which holds instance
Then store instance of Graph in graph property in Graph class
Now you can use in another class where you access graph instance like
