“allows external storage.” Is it disk storage? and does it show in app size in settings ?

#3

It just means that instead that large binary files are stored on the file system instead of the actual data store. This setting is managed from the model settings.

Thanks for the great course!

Is there any general rule of thumb in terms of from what file size (e.g., photo), it makes more sense to use the setting? For instance, I guess that if you are working with small resolution photos only, that option is not going to be meaningful; if so, how small should the photo size be? 100kb? 1Mb? Or, is this question not that important because the CoreData is smart enough to make appropriate decisions automatically?

You’ll have to make this decision. You learn more over here:
