    Google出了解决方案：
    将以下两个方法：
    SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
    SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key);
    前添加（void）即可：
    (void)SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
    (void)SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key);
    注：可能是因为Xcode8.0 beta的问题，估计Facebook过段时间会解决
