真实设备上的 Sqlite 不能工作，但在模拟器上工作

Question

我正在使用 sqlLite with this library，所以当我在模拟器上运行时它运行良好，但是当我尝试运行一个真实的设备时它给了我这个错误

错误：

/var/mobile/Containers/Data/Application/B8B355F9-6378-4862-9D06-84DA3FD06366/Documents
2019-01-02 19:54:23.476422+0200 Test[3626:1280621] [logging-persist] cannot open file at line 42249 of [95fbac39ba]
2019-01-02 19:54:23.476491+0200 Test[3626:1280621] [logging-persist] os_unix.c:42249: (0) open(/var/mobile/Containers/Data/Application/B8B355F9-6378-4862-9D06-84DA3FD06366/DocumentsTest.sqlite3) - Undefined error: 0 Can't connect to DB, Error is: Error Domain=SQLite.Result Code=0 "(null)", [:]

以及我连接到 dp 的代码：

    import Foundation
    import SQLite
    import SQLite3

    class Database{

    static let shared = Database()
    public let connection: Connection?
    public let databaseName = "Test.sqlite3"

    init() {
        let dbPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first as! String
        print(dbPath)
        do{
            connection = try Connection("\(dbPath)\(databaseName)")
        }catch{
            connection = nil
            let nserror = error as NSError
            print("Can't connect to DB, Error is: \(nserror), \(nserror.userInfo)")
        }
    }
}

您需要加一个“/”

 connection = try Connection("\(dbPath)/\(databaseName)")
