 有很多种创建更简洁的闭包的方法。如果一个闭包的类型已知，比如作为一个回调函数，你可以忽略参数的类型和返回值。单个语句闭包会把它语句的值当做结果返回。
 
 ```swift
-let mappedNumbers = numbers.map({ number in 3 * number })
-print(mappedNumbers)
+let sortedNumbers = numbers.sort { $0 > $1 }
+print(sortedNumbers)
 ```
 
 你可以通过参数位置而不是参数名字来引用参数——这个方法在非常短的闭包中非常有用。当一个闭包作为最后一个参数传给一个函数的时候，它可以直接跟在括号后面。当一个闭包是传给函数的唯一参数，你可以完全忽略括号。

 你可以像上面这样使用可选绑定来重写`possibleNumber`这个例子：
 
 ```swift
-if let actualNumber = possibleNumber.toInt() {
-    print("\(possibleNumber) has an integer value of \(actualNumber)")
-} else {
-    print("\(possibleNumber) could not be converted to an integer")
-}
-// 输出 "123 has an integer value of 123"
+if let actualNumber = Int(possibleNumber) {
+    print("\'\(possibleNumber)\' has an integer value of \(actualNumber)")
+} else {
+    print("\'\(possibleNumber)\' could not be converted to an integer")
+}
+// 输出 "'123' has an integer value of 123"
 ```
 
 这段代码可以被理解为：
