CoreData is a pain in the ass. It feels like it tries to be everything to everyone so it’s nothing to no one.

Are there any other decent alternatives for an iOS app?

Have a look at FMDB: https://github.com/ccgus/fmdb/

I don't know or use it personally. But the developer behind it is very experienced and sells the nice, tried and true image editor Acorn here. https://flyingmeat.com
