Question

这可能很简单但是，由于我在Swift上不是很有经验，所以我无法想象如何将这一行移植到Swift 2.0。

func setPasscode(identifier: String, passcode: String) {
    var dataFromString: NSData = passcode.dataUsingEncoding(NSUTF8StringEncoding)!;

    var keychainQuery = NSDictionary(objects: [kSecClassGenericPassword, identifier, dataFromString], forKeys: [kSecClass, kSecAttrService, kSecValueData])

    SecItemDelete(keychainQuery as CFDictionaryRef);
    var status: OSStatus = SecItemAdd(keychainQuery as CFDictionaryRef, nil);
}

错误消息：无法为类型＆＃39; NSDictionary＆＃39;调用初始化程序。使用类型＆＃39;的参数列表（对象：NSArray，forKeys：[CFString]）＆＃39;

Answer 1

let identifier = "someIdentifier"
let dataFromString = "someData"
let values = [kSecClassGenericPassword, identifier, dataFromString]
let keys: [NSString] = [kSecClass, kSecAttrService, kSecValueData]
let keychainQuery = NSDictionary(objects: values, forKeys: keys)

无法为类型＆＃39; NSDictionary＆＃39;调用初始化程序。在Swift2.0中
