ちょっと調べないと分からなかったので。

変換方法

Array

``````// Array -> NSArray
var nsarr: NSArray = NSArray(array: ["A", "B", "C"])
println(nsarr)

// NSArray -> Array
var arr: [String] = nsarr as [String]
println(arr)
``````
``````(
A,
B,
C
)
[A, B, C]
``````

Dictionary

``````// Dictionary -> NSDictionary
var nsdic: NSDictionary = NSDictionary(dictionary: ["key1": "value1", "key2": "value2"])
println(nsdic)

// NSDictionary -> Dictionary
var dic: Dictionary = nsdic as Dictionary
println(dic)
``````
``````{
key1 = value1;
key2 = value2;
}
[key2: value2, key1: value1]
``````

おまけ: Array of Dictionary

``````var sample: [Dictionary<String, AnyObject>] = [
["key1": "value1", "key2": "value2"],
["key3": "value3", "key4": "value4"]]

// Array of Dictionary -> NSArray of NSDictionary
var nsdicarr: NSArray = NSArray(array: sample)
println(nsdicarr)

// NSArray of NSDictionary -> Array of Dictionary
var dicarr: [Dictionary<String, AnyObject>] = nsdicarr as [Dictionary<String, AnyObject>]
println(dicarr)
``````
output
``````(
{
key1 = value1;
key2 = value2;
},
{
key3 = value3;
key4 = value4;
}
)
[[key2: value2, key1: value1], [key4: value4, key3: value3]]
``````
