推荐答案

从版本4.4.0开始，您可以从currentUser中获取iOS中的上次登录时间和创建时间:

You can, starting with version 4.4.0, get the last sign in time and creation time in iOS from the currentUser: https://firebase.google.com/support/release-notes/ios#4.4.0

Auth.auth().currentUser.metadata.lastSignInDate Auth.auth().currentUser.metadata.creationDate
