Static Block in Swift

Question

In Java, I use static block to execute some code when the class is called like in this example"

Class Name
 {
     static
     {
         for(int i = 0; i<10; i++)
         {

         }
     } 
 }

How do I translate that code in Swift?

You could do something like this,.

class SomeViewController : UIViewController {
    public static let formatter: DateFormatter = {
        let df = DateFormatter()
        df.dateFormat = "yyyy-MM-dd"
        return df
    }()
}

What does the leading `()` denote? – Antony Stubbs Feb 17 '22 at 21:32

Answering my own comment - it causes the closure to execute. From a Java perspective you could say it’s short hand for calling run() apply() execute() etc… – Antony Stubbs Feb 17 '22 at 22:30

I have been struggling with this same question for the last couple days. The solution that I found (although somewhat inelegant) is the use of main.swift.

This isn't really the same thing as a static block on a class in Java, but it may help with your particular issue.
