Yes: Use a database. That’s literally exactly what you’re describing. You have several choices, such as
CoreData — Integrated into the OS, lots of documentation, very powerful. Complex and has a steep learning curve IMHO.
SQLite — Built-in, lightweight. But the API is low-level and awkward, esp. if you don’t already know SQL. You’ll probably want to use it with an Obj-C wrapper like FMDB <https://github.com/ccgus/fmdb>.
Nanostore <https://github.com/tciuro/NanoStore> — A Cocoa API based on SQLite that provides a higher-level interface similar to property lists.
TouchDB <https://github.com/couchbaselabs/TouchDB-iOS> — Also a Cocoa API, also based on SQLite. Compatible with the CouchDB database. Very strong replication/synchronization features, should you ever want to sync your data to a server or another device. Written by me :)
