cocoa - OSX 10.9 Mavericks キーチェーン API が壊れていますか?

Question

OSX 10.9 Mavericks にアップグレードして以来、Keychain 関数が呼び出されるたびに不明な例外がスローされるため、Security フレームワークで Keychain API を使用できませんでした。キーチェーン ラッパーのさまざまな実装を試してみましたが、いずれもキーチェーン関数を呼び出すと不明な例外がスローされます。Apple の開発者サイトに投稿されたサンプル コードを試してみたところ、同じ問題が発生しました。これは既知の問題ですか? もしそうなら、修正の状況はどうなっていますか? キーチェーンを使用する方法はありますか? Apple の Web サイトからサンプル コードを以下に示します。リンクは次のとおりです。

//Call SecKeychainAddGenericPassword to add a new password to the keychain:
