在processResponseData函数中,我们尝试将接收到的Data转换为String。如果转换成功,我们会继续调用decodeUnicodeString函数来处理可能包含的 Unicode 字符。 3. 将 Unicode 数据转换为 String 下面我们将编写decodeUnicodeString函数,以解析 Unicode 字符串: // 解码 Unicode 字符串的函数funcdecodeUnicodeString(_unicodeString...
In the above code, we define a JSON string representing a person’s name and age. We then convert the JSON string intoDatausing thedata(using:)method, and pass it to thedecode(_:from:)method ofJSONDecoderto decode the JSON data into thePersonstruct. Converting Number to String Now, let...

var continuation: AsyncStream<String>.Continuation! let stream = AsyncStream<String> { continuation = $0 } 现在我们可以同时获得两者: 代码语言:javascript 复制 let (stream, continuation) = AsyncStream.makeStream(of: String.self) 这在需要在当前上下文之外访问延续的地方特别受欢迎,例如在不同的方法中。...

func do(data: Any?) { guard let string = data as? String else { return } // } do(1) do("") 以上面的例子为例,我们进行了as?转换,当data为String时才会进行处理。但是当do方法内String类型发生了改变函数,使用方并不知道已变更没有做相应的适配,这时候就会造成业务逻辑的错误。
Come for concise literals but stay for Regex builders — a new, declarative approach to string processing. We'll also explore the Unicode models in String and share how Swift Regex can make Unicode-correct... 25:17 Meet distributed actors in Swift WWDC22 iOS, iPadOS, macOS, tvOS, ...
