sir may i know why we can not access Product.discountedPrice(percentage: double)) outside the class
sir may i know why we can not access Product.discountedPrice(percentage: double)) outside the class when i use product. so it auto complete by product.discountedPrice(self: Product) is it necessary to access the discountedPrice function through the new variable.
Obviously I don't know what you code looks like so I can only give you a rough example using a variable, you'll have to move this around to get it to work with your class.
The reason you can't access your
outside your class is because you declared your variable within your class, Swift is really kind of pedantic about that kind of thing so you would be best declaring a global variable lets say declare something like this at the start of viewController or project.
View Contoller.Swift var discountedPrice : [Int] = 0 // if its an integer or var discountedPrice : [String] = "" // If on the off chance your using a string
and then in the class you should call the variable by using
discountedprice = 0 // instead of redefining it again with var
Hope this helps.
Thank you Sir, i got it
