模拟器中没有Touch ID / Face ID提示
[英]No Touch ID / Face ID prompt in simulator
问题描述
I am using the KeychainAccess keychain wrapper for Swift to save and read to the keychain using biometrics. 
我正在使用Swift的KeychainAccess钥匙串包装器来保存并使用生物识别技术读取钥匙串。
When running in the simulator (Xcode 10.1, iOS 12.1) the Touch ID / Face ID prompt/dialogue is not shown. 在模拟器（Xcode 10.1，iOS 12.1）中运行时，不会显示Touch ID / Face ID提示/对话框。 The value is written to and read from keychain without the user being asked to confirm with biometrics. 该值将写入钥匙串并从钥匙串读取，而不会要求用户使用生物识别技术进行确认。 When I run on a device the prompt comes as expected. 当我在设备上运行时，提示按预期进行。
It would seem that the simulator is always in a state where the biometrics is already approved, even though I had not activated the matching touch/face. 似乎模拟器始终处于生物识别已经被批准的状态，即使我没有激活匹配的触摸/面部。
Is this a bug or (or perhaps a feature) in the simulator or the SDK? 这是模拟器或SDK中的错误或（或可能是功能）吗？ I have an older Objective-C project that uses Apple's old KeychainWrapper, and there I get the prompt in the same simulator. 我有一个较旧的Objective-C项目，使用Apple的旧KeychainWrapper，我在同一个模拟器中得到提示。

You can use the following option to trigger Enrolled, Matching Touch/Face and Non-Matching Touch/Face 您可以使用以下选项触发已注册，匹配的触摸/面部和不匹配的触摸/面部
Simulator >> Hardware > Touch ID
Simulator >> Hardware > Face ID
