Issues and pull requests welcome!

Requirements

  • iOS 15.0+
  • Swift 5.0+

Installation

The recommended approach to use DittoSwiftTools in your project is using the Swift Package Manager.

  1. With your project open in Xcode go to File -> Add Packages, then search using "github.com/getditto/DittoSwiftTools" to find the DittoSwiftTools package.
Add Package Image
  1. Select "Add Package"
  2. Select which DittoSwiftTools products you would like, then select "Add Package"

If you are looking for compatibility with Ditto v3, please target the 3.0.0 release in the Swift Package Manager.

Usage

There are six targets in this package:

  • DittoPresenceViewer
  • DittoPeersList
  • DittoDiskUsage
  • DittoDataBrowser
  • DittoExportLogs
  • DittoExportData

1. Presence Viewer

The Presence Viewer displays a mesh graph that allows you to see all connected peers within the mesh and the transport each peer is using to make a connection.

Presence Viewer Image

First, make sure the "DittoPresenceViewer" is added to your Target. Then, use import DittoPresenceViewer to import the Presence Viewer.

You can use the Presence Viewer in SiwftUI or UIKit

SwiftUI

Use PresenceView(ditto: Ditto) and pass in your Ditto instance to display the mesh graph.

import DittoPresenceViewer

struct PresenceViewer: View{

    var body: some View {
        PresenceView(ditto: DittoManager.shared.ditto)
    }
}

UIKit

Call present and pass DittoPresenceView(ditto: DittoManager.shared.ditto).viewController as a parameter. Set animated to true.

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    present(DittoPresenceView(ditto: DittoManager.shared.ditto).viewController, animated: true) {
        if let selected = tableView.indexPathForSelectedRow {
            tableView.deselectRow(at: selected, animated: true)
        }
    }
}

2. Peers List

Peers List displays local and connected remote peers within the mesh in a list view, and the transport each peer is using to make a connection.

Peers List Image

You can use the Peers List in SiwftUI or UIKit

SwiftUI

Use PeersListView(ditto: Ditto), passing in your Ditto instance to display the peers list.

import DittoSwift

struct PeersListViewer: View {

   var body: some View {
       PeersListView(ditto: DittoManager.shared.ditto)
   }
}

UIKit

Pass PeersListView(ditto: Ditto) to a UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: PeersListView(ditto: DittoManager.shared.ditto))

present(vc, animated: true)

3. Disk Usage

Disk Usage allows you to see Ditto's file space usage.

Disk Usage Image

First, make sure the "DittoDiskUsage" is added to your Target. Then, use import DittoDiskUsage to import the Disk Usage.

SwiftUI

Use DittoDiskUsageView(ditto: Ditto) and pass in your Ditto instance.

import DittoDiskUsage

struct DiskUsageViewer: View {
    var body: some View {
        DittoDiskUsageView(ditto: DittoManager.shared.ditto)
    }
}

UIKit

Pass DittoDiskUsageView(ditto: Ditto) to a UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: DittoDiskUsageView(ditto: DittoManager.shared.ditto))

present(vc, animated: true)

4. Data Browser

The Ditto Data Browser allows you to view all your collections, documents within each collection and the properties/values of a document. With the Data Browser, you can observe any changes that are made to your collections and documents in real time.

Collections Image Document Image

Standalone App
If you are using the Data Browser as a standalone app, there is a button, Start Subscriptions, you must press in order to start syncing data. If you are embedding the Data Browser into another application then you do not need to press Start Subscriptions, as you should already have your subscriptions running.

First, make sure the "DittoDataBrowser" is added to your Target. Then, use import DittoDataBrowser to import the Data Browser.

SwiftUI

Use DataBrowser(ditto: Ditto) and pass in your Ditto instance to display the Data Browser.

import DittoDataBrowser

struct DataBrowserView: View {
    var body: some View {
       DataBrowser(ditto: DittoManager.shared.ditto)
    }
}

UIKit

Pass DataBrowser(ditto: Ditto) to a UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: DataBrowser(ditto: DittoManager.shared.ditto))

present(vc, animated: true)

5. Logging and Export Logs

Logging Level

Allows you to choose Ditto logging level at runtime.

Logging Level Image

SwiftUI + Combine

In your class conforming to the Observable Object protocol, e.g., DittoManager, create a published variable to store the selected logging option. The LoggingOptions enum is an extension on DittoLogger, defined in the DittoExportLogs module.

import Combine  
import DittoExportLogs  
import DittoSwift  
import Foundation  

class DittoManager: ObservableObject {  
    @Published var loggingOption: DittoLogger.LoggingOptions  
    private var cancellables = Set<AnyCancellable>()  
      
    init() {  
        self.loggingOption = DittoLogger.LoggingOptions.error  // initial level value
          
        // subscribe to loggingOption changes  
        // make sure log level is set _before_ starting ditto  
        $loggingOption  
            .sink { [weak self] logOption in  
                switch logOption {  
                case .disabled:  
                    DittoLogger.enabled = false  
                default:  
                    DittoLogger.enabled = true  
                    DittoLogger.minimumLogLevel = DittoLogLevel(rawValue: logOption.rawValue)!  
                }
            }
            .store(in: &cancellables)
 
        ... 

Create a SwiftUI view struct as a wrapper view to use as a subview or in a list, initializing with your Observable Object class instance. In the body, include the LoggingDetailsView, initializing with the published property. The LoggingDetailsView binds the published property to the logging level options picker, and selection changes are reflected back to your subscriber.

import DittoExportLogs
import DittoSwift
import SwiftUI

struct LoggingDetailsViewer: View {
    @ObservedObject var dittoManager = DittoManager.shared
    
    var body: some View {
        LoggingDetailsView(loggingOption: $dittoManager.loggingOption)
    }
}        

Export Logs

Allows you to export a file of the logs from your applcation as a zip file.

Export Logs Image

First, make sure the "DittoExportLogs" is added to your Target. Then, use import DittoExportLogs to import the Export Logs.

Important

Before calling ditto.startSync() we need to set the DittoLogger.setLogFileURL(<logFileURL>). This registers a file path where logs will be written to, whenever Ditto wants to issue a log (on top of emitting the log to the console). Use the LogFileConfig struct:

struct LogFileConfig {
    static let logsDirectoryName = "debug-logs"
    static let logFileName = "logs.txt"
    static let zippedLogFileName = "logs.zip"

    static var logsDirectory: URL! = {
        let directory = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask).first!
        return directory.appendingPathComponent(logsDirectoryName, isDirectory: true)
    }()

    static var logFileURL: URL! = {
        return Self.logsDirectory.appendingPathComponent(logFileName)
    }()

    static var zippedLogsURL: URL! = {
        let directory = FileManager.default.temporaryDirectory
        return directory.appendingPathComponent(zippedLogFileName)
    }()
    
    public static func createLogFileURL() -> URL? {
        do {
            try FileManager().createDirectory(at: self.logsDirectory,
                                              withIntermediateDirectories: true)
        } catch let error {
            assertionFailure("Failed to create logs directory: \(error)")
            return nil
        }

        return self.logFileURL
    }
}

and then before calling ditto.startSync() set the log file url with:

if let logFileURL = LogFileConfig.createLogFileURL() {
    DittoLogger.setLogFileURL(logFileURL)
}

Now we can call ExportLogs().

SwiftUI

Use ExportLogs() to export the logs. It is recommended to call ExportLogs from within a sheet.

.sheet(isPresented: $isPresented) {
    ExportLogs()
}

UIKit

Pass ExportLogs() to a UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: ExportLogs())

present(vc, animated: true)

6. Export Data Directory

ExportData allows you to export the Ditto store directory as a zip file.

Export Data

SwiftUI

Use ExportData(ditto: ditto) to get UIActivityViewController and call it within a sheet.

.sheet(isPresented: $isPresented) {
    ExportData(ditto: ditto)
}

UIKit

Pass UIActivityViewController (return value of ExportData(ditto: ditto)) to UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: ExportData(ditto: ditto))

present(vc, animated: true)

7. Presence Degradation Reporter

Tracks the status of your mesh, allowing to define the minimum of required peers that needs to be connected. Provides a callback function that will allow you to monitor the status of the mesh.

Screenshot 2024-02-20 at 5 14 18 PM

You can use the Presence Degradation Reporter in SiwftUI or UIKit

data provided in callback

settings: Settings
struct Settings {
    let expectedPeers: Int
    let reportApiEnabled: Bool
    let hasSeenExpectedPeers: Bool
    let sessionStartedAt: String
}

SwiftUI

Use PresenceDegradationView(ditto: DittoManager.shared.ditto!) { expectedPeers, remotePeers, settings in //handle data}, passing in your Ditto instance to display the peers list.

import DittoPresenceDegradation

struct PresenceDegradationViewer: View {
    
    var body: some View {
        PresenceDegradationView(ditto: <diito>) { expectedPeers, remotePeers, settings in
            //handle data
        }
    }
}

UIKit

Pass PresenceDegradationView(ditto: <ditto>) to a UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: PresenceDegradationView(ditto: <diito>))

present(vc, animated: true)

8. Permissions Health

Permissions Health allows you to see the status of ditto's required services and permissions.

Example: Wi-Fi, Bluetooth, Missing Permissions.

Screenshot 2024-02-28 at 12 47 28 PM

SwiftUI

import DittoPermissionsHealth

struct PermissionsHealthViewer: View {
    var body: some View {
        PermissionsHealth()
    }
}

UIKit

Pass UIActivityViewController (return value of PermissionsHealth()) to UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: PermissionsHealth())

present(vc, animated: true)

9. Heartbeat

The Ditto Heartbeat tool allows you to monitor, locally or remotely, the peers in your mesh.

Configure Heartbeat

These are the values you need to provide to the Heartbeat:

  1. Id - Unique value that identifies the device
  2. Interval - The frequency at which the Heartbeat will scrape the data
  3. Meta Data - This field is optional

There is a DittoHeartbeatConfig struct you can use to construct your configuration.

// Provided with the Heartbeat tool
public struct DittoHeartbeatConfig {
    public var id: String
    public var secondsInterval: Int
    public var metadata: [String: Any]?
    
    public init(id: String, secondsInterval: Int, metadata: [String : Any]? = nil) {
        self.id = id
        self.secondsInterval = secondsInterval
        self.metadata = metadata
    }
}

This tool generates a DittoHeartbeatInfo object with the given data:

public struct DittoHeartbeatInfo: Identifiable {
    public var id: String
    public var schema: String
    public var secondsInterval: Int
    public var lastUpdated: String
    public var sdk: String
    public var presenceSnapshotDirectlyConnectedPeersCount: Int { presenceSnapshotDirectlyConnectedPeers.count }
    public var presenceSnapshotDirectlyConnectedPeers: [DittoPeerConnection]
    public var metadata: [String: Any]
}

public struct DittoPeerConnection {
    public var deviceName: String
    public var sdk: String
    public var isConnectedToDittoCloud: Bool
    public var bluetooth: Int
    public var p2pWifi: Int
    public var lan: Int
    public var peerKey: String
}

You can either use the provided UI from this tool or you can read the DittoHeartbeatInfo data and create your own UI/use the data as you please.

Use provided UI:

SwiftUI

Use HeartbeatView(ditto: dittoModel.ditto!, config: heartbeatConfig), passing in your Ditto instance and your DittoHeartbeatConfig object.

import DittoHeartbeat

struct HeartbeatViewer: View {
    var body: some View {
        HeartbeatView(ditto: <ditto>, config: <heartbeatConfig>)
    }
}

UIKit

Pass HeartbeatView(ditto: <ditto>, config: <heartbeatConfig>) to a UIHostingController which will return a view controller you can use to present.

let vc = UIHostingController(rootView: HeartbeatView(ditto: <ditto>, config: <heartbeatConfig>))

**Read data only:**

Create a `HeartbeatVM(ditto: <ditto>` object and then call `startHeartbeat(config: DittoHeartbeatConfig, callback: @escaping HeartbeatCallback)`. You can access the data in the callback of `startHeartbeat`
```swift
var heartBeatVm = HeartbeatVM(ditto: DittoManager.shared.ditto!)
heartBeatVm.startHeartbeat(config: DittoHeartbeatConfig(secondsInterval: Int, metadata: metadata: [String:Any]? )) { heartbeatInfo in
        //use data
} 

Read data only:

Create a HeartbeatVM(ditto: <ditto> object and then call startHeartbeat(config: DittoHeartbeatConfig, callback: @escaping HeartbeatCallback). You can access the data in the callback of startHeartbeat

var heartBeatVm = HeartbeatVM(ditto: DittoManager.shared.ditto!)
heartBeatVm.startHeartbeat(config: DittoHeartbeatConfig(secondsInterval: Int, metadata: metadata: [String:Any]? )) { heartbeatInfo in
        //use data
} 

Ditto Tools Example App

The Ditto Tools Example App included in this repo allows you to try the DittoSwiftTools package in a standalone app. Open DittoToolsApp.xcodeproj in Xcode and build to a simulator or device.

Ditto Tools App Image

In the CONFIGURATION section of the tools list, click Change Identity to configure and start, or restart, the Ditto session. Select Online Playground, Offline Playground, or Online With Authentication in the Identity picker. Then add the appropriate App ID and other values from your Ditto portal app and click Restart Ditto.

Change Identity View Image

This will initialize the Ditto instance and enable you to try the different features.
