- [Instructor] So great, we stored our data in the keychain … and we got a success back, … so we know it worked, right? … Well, I don't know about you, … but I'm always a little skeptical, … so sometimes I like to check for myself. … Well, since we ran this in the simulator, we can. … We have access to the database where it's stored in, … and I'll do that in the terminal. … So in the terminal, … I'm going to navigate to my home directory, … Library, Developer, CoreSimulator, and Devices, … and in here we have a folder for each of the devices … and the device list. … So I'm going to look at the device list, … and I've been using the iPhone 11 Pro Max, … so here is the directory that I want. … So I'm going to copy that … and then I'm going to change to that directory. … And in here we can go to data, Library, Keychains, … and if we do an ls, … we can see the keychain database right here. … So I'm going to copy this, … and I have a SQLite DB browser, … so I'm going to type open and paste in the database name. …
