Read through my app's Core Data files (.sqlite, .sqlite-wal)

I am trying to browse through the data written by Core Data in an iOS app I am developing.

After the app ran for a while, and I assume collected some data, I now wish to look through the data and see what was written.

I have tried getting and browsing the .sqlite file through getting the app container from the device (Xcode > Devices > myApp > Download Container...).

I got the db files, myAppDB.sqlite, myAppDB.sqlite-shm and myAppDB.sqlite-wal.

When trying to look through them, it seems like the .sqlite is an empty table (except maybe some generic CoreData/sqlite stuff), and the -wal file has all the info.

The thing is I was only able to know that the wal has useful data when opening it with TextEdit, which din't show it in a very readable way, and when I tried to use an SQLite Manager app I an alert saying the wal is encrypted and I am asked to put a password...

For what it matters, I am writing a framework which handles the db (the model file and the code for writing data is inside the framework), then I have this framework running in an app I am developing. This is the code I use to create the store from within the framework (using MagicalRecord):

NSBundle *frameworkBundle = [NSBundle bundleForClass:[self class]];
[MagicalRecord setDefaultModelNamed:@"myAppStore.momd" inBundle:frameworkBundle];

NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"myAppStoreDB.sqlite"];
[MagicalRecord setupCoreDataStackWithStoreAtURL:storeURL];

tl;dr

How can I browse through the info written by Core Data of the app I am developing?
