Iterate Within For Loops More Easily with Iterable In #SalesforceWinter24Release

You can now iterate through lists or sets effortlessly using the Iterable variable in a for loop. 

Here's an example that demonstrates how to use the Iterable variable to iterate through a list of strings:

Iterable<String> stringIterator = new List<String>{'Hello', 'World!'};

for (String str : stringIterator) {

  System.debug(str);

}

And here's another example that showcases implementing an Iterable interface, followed by iterating through the strings in the returned set of strings:

public class MyIterable implements Iterable<String> {

  public Iterator<String> iterator() {

    return new Set<String>{'Hello', 'World!'}.iterator();

  }

}

for (String str : new MyIterable()) {

  System.debug(str);

}
