Swift - Populate core data from premade sqlite file - swift

Question

Not the same question as here.
I have a premade sqlite file that has three columns: chapter, verseNumber and verseText. My core data entity has the same name for its attributes. How do I populate the core data database from my sqlite file?

Answer 1

Core Data can not read arbitrary SQLite files. You would have to convert the file into a Core Data database manually. The format that Core Data uses to read from / write to SQLite is proprietary.
You have to use SQLite directly to read the data. I'd suggest using something like FMDB for reading the data. To put the data into a Core Data store, you should follow the guidelines of Efficiently Importing Data.

Answer 2

Here is what I ended up doing:
#IBAction func getSQLDB (sender: NSButton) {
let documentsFolder = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
let path = documentsFolder.stringByAppendingPathComponent("kjv.db")
println(documentsFolder)
let database = FMDatabase(path: path)
if !database.open() {
println("Unable to open database")
return
}
//if let rs = database.executeQuery("SELECT * FROM bible WHERE (book = 'Gen') AND (chapter = '1')", withArgumentsInArray: nil) {
if let rs = database.executeQuery("SELECT * FROM bible WHERE (book = 'Genesis') OR (book = 'Exodus')", withArgumentsInArray: nil) {
while rs.next() {
let content = rs.stringForColumn("content")
let verseNumber: Int! = rs.stringForColumn("verse").toInt()
let chapter: Int! = rs.stringForColumn("chapter").toInt()
let name = rs.stringForColumn("book")
// Loops through all the information from the query and creates a book
makeBook(name, content: content, chapter: chapter, verseNumber: verseNumber)
}
} else {
println("select failed: \(database.lastErrorMessage())")
}
database.close()
}
