预填充的SQLite DB文件不保存更新?

我已经创建了SQLite DB文件,并在模拟器的应用程序中填充了数据,现在我需要在新项目中使用相同的数据库和填充的数据。 我已将SQLite文件复制到新项目中,但每次我更新一行(删除/编辑)时,数据都会更新,直到下一次运行时,并且在重新运行项目后,我的数据和SQLite文件就像刚刚复制到项目中一样。

注意:“clearData(SID:Int)”函数删除一行,但在xcode中重新运行项目后,该行就在那里了。。。

以下是我的数据库结构:

import SQLite

var db: Connection!
let sherTable = Table("Sher");
let ID = Expression<Int>("SID");
let Fname = Expression<String?>("Fname");
let Ename = Expression<String?>("Ename");
let Flike = Expression<Bool?>("Flike");
let Elike = Expression<Bool?>("Elike");

let byteTable = Table("Byte");
let BID = Expression<Int>("BID");
let BSID = Expression<Int>("SID");
let Byte = Expression<String?>("Byte");
let searchText = Expression<String?>("searchText");
let BIsFarsi = Expression<Bool?>("IsFarsi");

let maniTable = Table("Mani");
let MID = Expression<Int>("MID");
let MSID = Expression<Int>("SID");
let Word = Expression<String?>("Word");
let Meaning = Expression<String?>("Meaning");
let MIsFarsi = Expression<Bool?>("IsFarsi");

func connectToDB() {
    do {
        let path = Bundle.main.path(forResource: "hafezDb", ofType: "sqlite3")!;

        let tmp = try Connection(path);
        db = tmp;
    } catch {
        print(error);
    }
}

func clearData(_ SID: Int) {
    let sher = sherTable.filter(ID == SID);
    let u = sher.update(Flike <- !Flike);
    do {
        try db.run(u);
    } catch {
        print(error)
    }
}
