Argument type ‘SDKLoggingBehavior?’ does not conform to expected type
‘Sequence’

在线

return Set(behaviors)

我已经使用cocoapods安装了最新的FBSDK.

我将如何解决此问题,还是等待来自FB的更新SDK？

extension SDKSettings {
      /**
       Current logging behaviors of Facebook SDK.
       The default enabled behavior is `.DeveloperErrors` only.
       */
      public static var enabledLoggingBehaviors: Set<SDKLoggingBehavior> {
        get {
          let behaviors = FBSDKSettings.loggingBehavior().flatMap { object -> SDKLoggingBehavior? in
            if let value = object as? String {
              return SDKLoggingBehavior(sdkStringValue: value)
            }
            return nil
          }
          return Set(behaviors)
        }
        set {
          let behaviors = newValue.map({ $0.sdkStringValue })
          FBSDKSettings.setLoggingBehavior(Set(behaviors))
        }
      }

      /**
       Enable a particular Facebook SDK logging behavior.

       - parameter behavior: The behavior to enable
       */
      public static func enableLoggingBehavior(_ behavior: SDKLoggingBehavior) {
        FBSDKSettings.enableLoggingBehavior(behavior.sdkStringValue)
      }

      /**
       Disable a particular Facebook SDK logging behavior.

       - parameter behavior: The behavior to disable.
       */
      public static func disableLoggingBehavior(_ behavior: SDKLoggingBehavior) {
        FBSDKSettings.disableLoggingBehavior(behavior.sdkStringValue)
      }
    }
}
