I have a json that I could parse with SwiftyJSON :
if let title = json["items"][2]["title"].string {
println("title : \(title)")
}
Works perfectly.
But I couldn't loop through it. I tried two methods, the first one is
// TUTO :
//If json is .Dictionary
for (key: String, subJson: JSON) in json {
...
}
// WHAT I DID :
for (key: "title", subJson: json["items"]) in json {
...
}
XCode didn't accept the for loop declaration.
The second method :
// TUTO :
if let appArray = json["feed"]["entry"].arrayValue {
...
}
// WHAT I DID :
if let tab = json["items"].arrayValue {
...
}
XCode didn't accept the if statement.
What am I doing wrong ?
If you want loop through json["items"]
array, try:
for (key, subJson) in json["items"] {
if let title = subJson["title"].string {
println(title)
}
}
As for the second method, .arrayValue
returns non Optional
array, you should use .array
instead:
if let items = json["items"].array {
for item in items {
if let title = item["title"].string {
println(title)
}
}
}
