![]() Some of this stuff is amazing: in 2006, Apple added movies to the iTunes Store that were 640 × 480 pixels, but you can now stream movies in HD resolution and (pretend) 4K. The average internet connection in the United States is about six times as fast as it was just ten years ago, but instead of making it faster to browse the same types of websites, we’re simply occupying that extra bandwidth with more stuff. Previously: Switching From RSS to Apple News Format.Īpple News iOS iOS 11 Mac macOS 10.13 High Sierra This Blog TidBITS Web You can follow this blog on Apple News here. However, Apple subsequently told me that the Apple News algorithm also takes some of its cues from those names, so I’ve added more sections that match up with topic names (Apple, Mac, iOS, Cybersecurity, and so on) that people can find in Apple News when searching for specific topics of interest. Most notably, I was told that Apple News cares quite deeply about the number of people who follow a particular publication-the more followers, the more likely Apple News is to recommend that publication’s articles to other people. Since we publish only about 50 articles per month, whereas a large publisher might release several times that per day, I was told that it could take several months before the algorithm knew what to do with our content. Language Design Memory Management Objective-C ProgrammingĪpple News is focused on large publishers and therefore needs quite a number of articles for training its natural language parser. If you use -Wnullable-to-nonnull-conversion and nullability annotations on local variables and properties, you get proper warnings when you pass a _Nullable to a _Nonnull parameter or assign a _Nullable rvalue to a _Nonnull lvalue.Īnd if you ever need to cast a _Nullable to a _Nonnull, this is the safe way to do so. ![]() This pattern becomes boilerplate code! It is possible to shrink the lines by using custom helper macros, but you still have to write them and have them available in your project. Imagine a piece of code that uses a lot of blocks, including nested blocks where on completion you want to do something else asynchronously, so you have to make a second strongSelf. If you pass in a nullable pointer variable (not a nil constant), this is silently allowed Unfortunately the only observable check that the Objective-C compiler does with that is that it prevents you from passing the nil constant in places where a nonnull type is expected. With those you can express an intent that a pointer to an object can never be nil. In 2015 Xcode 6.3 introduced nullability annotations to Objective-C. Thus they are not meant to turn Objective-C into a modern experimental language like Swift, but should make programming experience better and reduce boilerplate. The features listed here are chosen to have a relatively small scope in order to be implemented without major changes and in a backwards compatible way in the spirit of Objective-C.
