iOS Helper

  Xcode 13 arrived at WWDC21 and includes a huge range of new features, improvements, and performance enhancements. In this article I’m going to walk you through all the key changes, so you can get up to speed quickly, but before I start I need to make two things clear: First, no, I don’t have beta access to Xcode Cloud or the new Swift Playgrounds.  Trust me, I wish I did! Both of these things look likely to be significant upgrades for the Swift community, and I’m really keen to try them out at the earliest opportunity.  And second, you might immediately note that Xcode hides your file extensions by default in the project navigator.

No need to reinvent a "factory" system. No need for a specific constructor mechanism at the language level. This helps keeping the language simple and powerful. And, by the way, meta-classes are objects too! Dynamic typing As in Ruby, Python, Smalltalk, Groovy… Extremely useful because we don’t always know beforehand what our objects are going to be at run-time. Dynamic typing in Objective-C is simple to use. For example, this declares a variable that can hold a reference to an object: id myObject; Optional static typing Still, Objective-C also has ...
