Question

Answer 1

In case of any one faced this problem in Swift. Solution will be:

let dbName = "first.db"
static let shared = DatabaseManger()
var db: OpaquePointer?


private init(){
    print("singletone initialized")
    sqlite3_shutdown();
    let dbPath = try! FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
        .appendingPathComponent(dbName)
    if sqlite3_open_v2(dbPath.path, &db, SQLITE_OPEN_CREATE | SQLITE_OPEN_READWRITE | SQLITE_OPEN_FULLMUTEX, nil) == SQLITE_OK {
        print("Successfully opened database connection at \(dbPath.path)")
    }
    else {
        print("unable to open database connection")
    }
}

This code tested in swift version 4.0 and 4.2
