Ibm mobilefirst 当从安全适配器请求数据时，IBM MFP 8.0 ios崩溃

我已经实现了以下功能：

使用自定义安全检查创建适配器

创建作用域“main”并将其分配给我的安全检查

创建用于使用访问数据的适配器 @OAuthSecurity（scope=“main”）

从SecurityCheckChallengeHandler继承的IOS类

IOS应用程序在从适配器请求数据时崩溃。 如果我禁用安全检查，一切正常。应用程序在调用“handleChallenge”前崩溃

从XCode控制台记录：

One of the two will be used. Which one is undefined.

这可能是因为Xcode 8中要求添加“密钥链共享”功能（从Xcode中的“功能”选项卡）。我看到了应用程序在MauliLe1.1基金会8的崩溃。

尝试添加缺少的（？）功能，看看这是否解决了崩溃问题

有关参考信息，请参见此处：

注意：使用Xcode 8时，在iOS模拟器中运行iOS应用程序时，密钥链共享功能是必需的。在构建Xcode项目之前，需要手动启用此功能

请提供实际可复制的样本应用程序和安全检查，以便进行调试。
