What is equivalent to @autoreleasepool in Swift?

Question

In Swift, I noticed that there is no @autoreleasepool{} construct, although Swift uses ARC. What is the correct way to manage autoreleasepool in Swift, or was it removed for some reason?

Answer 1

This is described in detail in WWDC 2014 video number 418, “Improving Your Application with Tools,” which you can also download as a PDF.

But, in short, the syntax is:

 autoreleasepool { /* code */ } 

Answer 2

Just FYI, Xcode constructed the complete code as follows:

 autoreleasepool({ () -> () in // code }) 

Guess that parentheses indicate closing functions.

Answer 3

There is! It is simply not mentioned anywhere.

 autoreleasepool { Do things.... }
