表達式的類型在沒有更多上下文的情況下是模糊的Swift

Question

let contactDict: NSDictionary = ["identifier":singleContact.identifier,"firstName":singleContact.firstName, "lastName":singleContact.lastName,"email":singleContact.email,"phone":singleContact.phone,"contactImage":singleContact.contactImage] 

我有類型的表達式是模棱兩可的沒有更多的上下文錯誤。我試圖通過下面的表達式解決它

let contactDict: NSDictionary: [NSObject: AnyObject] 

但這仍然顯示一個錯誤，即連續的語句必須分開;

請幫我糾正這個錯誤。

Answer 1

你得到，因爲兩個冒號的連續語句錯誤...

let contactDict: NSDictionary: [NSObject: AnyObject] 

應該是這樣的......

let contacts: [NSObject: AnyObject] = ... 

或...

let contacts: Dictionary<NSObject, AnyObject> = ... 

請注意，當您使用單詞Dictionary或NSDictionary表示格式不使用括號ts：Dictionary<key, value>。如果你仍然得到明確的錯誤，試圖用一個空的字典字面創造它，然後追加：

var contacts: Dictionary<NSObject, AnyObject> = [:] 
contacts[key] = value 

或...

var contacts: Dictionary<NSObject, AnyObject> = [:] 
contacts += [...]
