Hi @JohnEstropia,

Is there any way to find out if a database already exists before adding it? E.g. I need to do some pre-setup stuff if the user had no database.

Thanks a lot

@mrichtsfeld If you just need to check if the file exists, you can use SQLiteStore to query FileManager:

let storage = SQLiteStore(fileName: "my.sqlite")
if FileManager.default.fileExists(atPath: storage.fileURL.path) {
    // ... pre setup stuff
}

What does pre setup stuff mean? How am I able to use this sqlite database?

@HristiyanZahariev You can initialize an SQLiteStore with your own file URL:

CoreStore.defaultStack = DataStack(
    xcodeModelName: "Model", // your xcdatamodeld name
    bundle: Bundle(for: type(of: self))
)
try CoreStore.addStorageAndWait(
    SQLiteStore(
        fileURL: yourFileURL // here
    )
)
