[英]How to parse particular JSON in Swift
To parse a JSON, as I found also on the web, I usually used this kind of code: 正如我在网络上发现的,为了解析JSON,我通常使用以下代码:
guard let results = receivedUserJSON["results"] as? [String: Any] else {
print("Error interpreting results")
return
}
This time I have a problem, because it seems to end in the else of this guard let. 这次我有一个问题,因为它似乎以此后卫让步而告终。 The JSON has the following structure:
JSON具有以下结构:

},

What should I do to properly parse this JSON? 我应该怎么做才能正确解析此JSON? I would prefer not to go for the Codable solution because I don't need all of these values.
我不希望使用Codable解决方案,因为我不需要所有这些值。
PS: I know the json is correct because I tried and printed it with: PS:我知道json是正确的,因为我尝试并使用以下命令将其打印出来:
if let JSONString = String(data: responseData, encoding: String.Encoding.utf8) {
print(JSONString)
}
results
is an array results
是一个数组
guard let results = receivedUserJSON["results"] as? [[String:Any]] else {
print("Error interpreting results")
return
}
I see no value for it to be an array as it contains 1 element so you may think to alter this json 我认为它是一个数组,因为它包含1个元素,因此没有任何价值,因此您可能会考虑更改此json
current strucsture 目前的结构
{
"results": [{}],
"info": {
"seed": "dd971cddf636d2d7",
"results": 1,
"page": 1,
"version": "1.2"
}
}
you may alter it to 您可以将其更改为
{
"results": {},
"info": {
"seed": "dd971cddf636d2d7",
"results": 1,
"page": 1,
"version": "1.2"
}
}
