swift 2.0 healthkit requestAuthorizationToShareTypes - 表达式类型在没有更多上下文的情况下不明确

Question

从 swift 1.2 转换为 2.0 后，出现以下错误：没有更多上下文，表达式类型不明确当我请求授权时如下：

healthKitStore.requestAuthorizationToShareTypes(writeTypes: healthKitTypesToWrite, readTypes: healthKitTypesToRead,completion:  { success, error in
        if success {
            print("SUCCESS")
        } else {
            print(error.description)
        }
        })

有什么想法吗？

Answer 1

我终于解决了这个问题，不确定它与错误消息本身有什么关系。

1) healthKitTypesToRead and write: 从 Set ( [ ] ) 中删除了 [ ]

2) 创建了一个新的完成二重体

3) 更改调用如下

示例：

let healthKitTypesToRead = Set(
        arrayLiteral: HKObjectType.characteristicTypeForIdentifier(HKCharacteristicTypeIdentifierDateOfBirth)!,
        HKObjectType.characteristicTypeForIdentifier(HKCharacteristicTypeIdentifierBiologicalSex)!,
        HKObjectType.workoutType()
        )

let newCompletion: ((Bool, NSError?) -> Void) = {
        (success, error) -> Void in

        if !success {
            print("You didn't allow HealthKit to access these write data types.\nThe error was:\n \(error!.description).")

            return
        }
    }


healthKitStore.requestAuthorizationToShareTypes(healthKitTypesToWrite, readTypes: healthKitTypesToRead, completion: newCompletion)

现在代码可以正确编译

swift 2.0 healthkit requestAuthorizationToShareTypes - 表达式类型在没有更多上下文的情况下不明确

swift 2.0 healthkit requestAuthorizationToShareTypes - Type of expression is ambiguous without more context
