我正在
Swift中开发一个iOS应用程序.
当我将Xcode更新为7.0时,我在swiftyJSON中遇到错误.
当我将Xcode更新为7.0时,我在swiftyJSON中遇到错误.
static func fromObject(object: AnyObject) -> JSONValue? {
switch object {
case let value as NSString:
return JSONValue.JSONString(value as String)
case let value as NSNumber:
return JSONValue.JSONNumber(value)
case let value as NSNull:
return JSONValue.JSONNull
case let value as NSDictionary:
var jsonObject: [String:JSONValue] = [:]
for (k:AnyObject,v:AnyObject) in value {// **THIS LINE- error: "Definition conflicts with prevIoUs value"**
if let k = k as? NSString {
if let v = JSONValue.fromObject(v) {
jsonObject[k] = v
} else {
return nil
}
}
}
有什么问题？你能帮忙吗？
解决方法
for (k:AnyObject,v:AnyObject) in value { .. }
必须用Swift 2编写
for (k,v) : (AnyObject,AnyObject) in value { .. }
从Xcode 7发行说明：
Type annotations are no longer allowed in patterns and are considered
part of the outlying declaration. This means that code prevIoUsly
written as:06002
needs to be written as:
06003
if an explicit type annotation is needed. The former Syntax was
ambiguous with tuple element labels.
但在您的情况下,实际上根本不需要显式注释：
for (k,v) in value { .. }
因为NSDictionary.Generator已经被定义为生成器返回(key：AnyObject,value：AnyObject)元素.
