如何在Swift中初始化NSData中的字符串 - How to initialise a string from NSData in Swift

问题：

I have been trying to initialise a string from NSData in Swift. 我一直在尝试从Swift中的NSData初始化一个字符串。

In the NSString Cocoa Documentation Apple is saying you have to use this: 在NSString Cocoa Documentation中， Apple说你必须使用它：

 init(data data: NSData!, encoding encoding: UInt)

However Apple did not include any example for usage or where to put the init . 但是，Apple没有包含任何使用示例或在哪里放置init 。

I am trying to convert the following code from Objective-C to Swift 我试图将以下代码从Objective-C转换为Swift

NSString *string;
string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

I have been trying a lot of possible syntaxes such as the following (of course it did not work): 我一直在尝试很多可能的语法，例如以下（当然它不起作用）：

var string:NSString!
string = init(data: fooData,encoding: NSUTF8StringEncoding)
