Establishing a Read-Write connection to a database in SQLite.swift

Asked 2022-Feb-21 at 23:55

I'm working a project where I need to use a SQLite database to read, create , and edit different objects. I thought I had established the connection properly but, it turns out I had only established a read only connection. How do I modify this code to be a read-write connection using SQLite.swift

When database created in your document directory it will be there permanently till user delete the app or you delete that directory.
so read and write connection will occur when you save your sql file in this directory.
as you wanted I make a new example for you that I created recently.

Error 'compile swift source files (arm64)' when building project with Xcode 13

Asked 2022-Jan-09 at 22:23

NOTE: I know that there are many answers related to these questions, but I've tried each of them, and when I am not able to resolve it with those, I am posting question here. Hence, I request you not to mark it as a duplicate.

I am developing an app with Xcode 13.0 (13A233) on Macbook with an M1 chip. After updating pods to the latest version, the pods are complaining about error

CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compiler (in target 'Alamofire' from project 'Pods')

and not building for either real devices or simulators.

I'm including the following pods in the project:

Alamofire
IQKeyboardManager
NVActivityIndicatorView
FillableLoaders
SQlite.Swift
SDWebImage
SwiftDataTables

I've already applied the following solutions for the main project and all pods projects:

Upon updating pods, clean build folder (using Shift + Command + K)
Excluding arm64 architecture for 'Any iOS Simulator SDK' from Excluded architectures
Set 'YES' to 'Build Active Architecture Only'
There is no field called 'VALID_ARCHS' in the User-Defined section

You can see Error details on this screenshot.

Any quick response with a proper solution will be much appreciated. Thank you!

I finally solved this problem. As Kiril S. suggested, SQLite.swift only works if "import SQLite" is used. However, as far as I can tell, "import SQLite" can only be used without errors in a file that contains no Views. When I use "import SQLite" in a file with any View (like ContentView.swift) I get multiple error messages. If I create a new Swift file without any View, everything works fine.

QUESTION

String to date conversion sometimes returns nil with DateFormatter

Asked 2021-Dec-11 at 03:39

I just read over this post which details that you need to set a locale before the format before attempting to convert a given string back to a date.

I have the below code that follows that format but the conversion from string to date still seems to return nil though in the playground it seems to work fine.

...

ANSWER

Answered 2021-Dec-11 at 03:39

Answer for your question (string to date is nil): While converting from string to date, you have to use the same format as String. I assume the originalDate from your comments. You have to change your code like this

QUESTION

Where to store a SQLite DB connection with iOS?

Asked 2021-Nov-18 at 19:39

I create a SQLite connection with SQLite.swift but I'm not sure where to store the DB connection so I can use it during the duration that a user has the app open across various views.

Is using UserDefaults here an appropriate case? Or EnvironmentObject?

What is the recommendation with iOS apps in terms of keeping a DB connection open for reuse?

...

ANSWER

Answered 2021-Nov-18 at 19:39

Is using UserDefaults here an appropriate case?

Definitely not. Like you said yourself: you want it to exist while the app is open. While UserDefaults is for things you want to store when app is not running.

Or EnvironmentObject?

You could, but semantically it's still wrong: Apple defines it as "A property wrapper type for an observable object supplied by a parent or ancestor view.", which doesn't really fit the DB connection. It's not an observable object with states.

Ideally you step back and look at a more generic architecture of your app.

Views want data in a specific format. They don't care where the data is coming from.
The fact that data is coming from DB is an implementation detail - tomorrow you may decide to retrieve it from remote server, and you don't want to change every single view because of that.

So what you really want is

View talks to some sort of "data provider" interface that defines an interface by which views can get their data regardless of where it's stored.
Your implementation of "data provider" is to talk to the local database (currently, but it can changed base don your needs).

In this structure the DB connection(s) are managed by data provider, and do not need to be shared with anyone. And your views will actually use Observable objects, except those observable objects are data itself, not the connection to database (and in fact views will not "know" where the data is coming from).

I will not go into details on how to make that model happen - there are many other details here (like what's overall architecture of your app), but this is the gist of the idea.

ANSWER

Answered 2021-Nov-12 at 16:27

There are various good / bad / ugly ways of handling this, and creating the db in main struct, may be a considered a bad way.

A better approach is to wrap all sqlite code in one of your own implementations. As an example, check Wrapping the Database Connection section in this tutorial

I managed to figure out the answer. If anyone ran into this problem or the same question this is how I managed to solve it. Still not sure if it is the correct way. Basically you need to recreate the table with the columns just like in the example but with the name of your columns. Create a table and name it the exact name as the table in your db.

Unable to find GlobalSQLite file for capacitor-community/sqlite in Ionic 5

Asked 2021-Apr-09 at 22:18

In my Ionic 5 app, I am using the capacitor-community/sqlite plugin. I am successfully able to create and use an encrypted db with this plugin. To use encryption a secret is required and the following is maintained in the official documentation as of today.

Defining your own secret and newsecret keys (encryption only)

in IOS, go to the Pod/Development Pods/capacitor-sqlite/GlobalSQLite.swift file

in Android, go to capacitor-sqlite/java/com.jeep.plugin.capacitor/cdssUtils/GlobalSQLite.java and update the default values before building your app.

in Electron, go to YOUR_APP/electron/plugins/plugin.js-xxxx.js and search for class GlobalSQLite and modify the this.secretand
this.newsecret parameters.

I have searched for files GlobalSQLite.swift and GlobalSQLite.java in IOS and android respectively but there are no such files present. Also, the file paths are not available. I am not sure how to get these files to set my secret in the app. Please help.

You should look for the GlobalSQLite.java in node_modules\@capacitor-community\sqlite\android\src\main\java\com\getcapacitor\community\database\sqlite\SQLite. After changing the secrets you may need to sync the platforms with ionic cap sync.

How to Sum a column as a Double using GRDB

I'm trying to convert my app from SQLite.swift to GRDB and I have run into a snag. I need to sum three separate columns and then do some math with the column totals. All three of the columns are stored in the Db as Real numbers which I believe makes them Doubles.

I use like with lowercaseString and Russian symbols but LOWER doesn't convert them to lowercase in the query. I tried to create my own function but it didn't work for me. How to solve this problem?

Having studied the documentation of SQLite, I learned that you need to connect the ICU library. How can this be done in this plugin?

ANSWER

Answered 2020-Nov-16 at 11:25

SQLite LOWER is only for ASCII. If you want to get case insensitive for Russian (or any other symbols besides ASCII), use FTS3/FTS4 https://www.sqlite.org/fts3.html (or FTS5 https://www.sqlite.org/fts5.html).

SQLite.swift has the corresponding full text search modules https://github.com/stephencelis/SQLite.swift/blob/master/Documentation/Index.md#full-text-search

To use it in your project with existing database, you should make connection to virtual table via FTS module and filter the query using .match
