defined in this agreement. The Generate method is used to generate a list of each element of the desired iteration. In addition, the ontology of generator is Generatortype, which is also a protocol that represents each element object of the required iteration, so we're going to do the second step.The second step is to implement the Generatortype protocol. This protocol is relatively simple, just a public mutating func next ()-Self.element interface method. This element can be used to specify th

as two constants, not variables, because Teneighty and alsoteneighty itself store only the reference value of the Videomode instance, not the Videomode instance itself , so you change the properties of the referenced class instance by their changes to the properties of the class instance itself, not the reference itself.Because the class is a reference type, as shown in the example above, multiple variables or constants may refer to the same instance of a class. To determine whether two constan

法习惯和 try? try! 类似.* 数组具体化类型声明为 Any / AnyObject 时,数组内可同时存放多种类型不兼容的实例.Nested Types* 支持类型嵌套定义,这已经是很大的突破了.* 即使在函数内部,也可以定义新的类型.* 可以用.语法,访问嵌套定义的类型.Extensions* extensions 和 categories 的重要区别之一是,前者不需要写名字.* extensions 不允许覆盖已有方法,且不同 extentsion 中的方法签名也不允许重复.* extentsion 扩展的东西,是可以被子类继承的.Protocols* 在swift 的设定中, protocol 也属于 type,可以用于任何 type 适用的场景.* 在类型声明遵循某协议以外的位置,书写符合协议的方法是,用 连接多个协议,如 APBPCP.* protocol 可以在 extension 中定义自己的方法,任意遵循此协议的类型的实例都可以调用此协议自己的方法实现. --> 可以在

Closures are functional self-contained modules that can be passed and used in code. Closures in swift are similar to blocks in C and objective-C, and Lambdas in other programming languages. Closure is acceptable. CaptureAnd store references to any constants and variables in the context. This is the so-called closure and enclose these constants and variables, commonly known as closures.
