After reading the Apple Developer document (Apple Developer Docs), I found that: "The Xcode debugger includes an interactive version of the Swift language called REPL (read-eval-print-loop) ... can be accessed through the Xcode console or terminal. Unfortunately, it doesn't tell you how to access from the terminal. Fortunately, this is not a difficult thing. Enter the following command (whichever beta you use to change the app's name) Copy Co

array, we can also convert the array coercion type to a specific type. Unlike converting from Nsarray class to anyobject[], converting objects from Anyobject types to explicit types does not guarantee success. Converting from anyobject[] to sometype[] Returns a value of optional, as it is not until the runtime compiler knows whether an object of Anyobject can be cast to a particular type. For example, if we know that a swift array contains only an in

overhead of building and running an app.Swift is a newcomer-friendly language and is the first industry-standard system programming language to use as easily as a scripting language. It supports playground (which can be seen in writing code colleagues, of course, if your machine is on hold), a revolutionary new improvement that allows developers to see the results of the run as soon as they write swift cod

The Anyobject protocol allows you to write type-safe Swift code while maintaining the flexibility of untyped objects. B

is the enemy that programmers face when trying to find and fix some random crash, or to stop abnormal behavior.The optional type in swift code makes the possibility of a nil optional value very clear, which means it can generate a compiler error when you write down a bad piece of code. This creates a loop of short-range feedback that allows the programmer to write code with the target. The problem can be fixed when the code is written, which saves yo

language replace Objective-C, or is it just a supplement to Objective-C? By referencing Apple's official statement, "Objective-C will not disappear. Swift and Objective-C can be used for both Cocoa and cococoatouch development ." Therefore, you can continue to use Objective-C. However, apple seems to encourage you to use Swift for new development, rather than wanting you to rewrite all Objective-C code. We

In addition to the release of IOS8 and Max OS X 10.10, Apple released a new programming language, Swift, at this year's WWDC conference. It has to be said that Swift has a big change and makes programming easier, and the following describes the definition of constants and variables for Swift, the use of basic control statements:It is important to note that
