iOS SDK

iOS SDK allows you to add an 2GIS map to your iOS application. Using the SDK, you can display a map on the screen, get information about map objects, use the navigator, build routes, and so on.

See SDK usage examples in the Examples section. For a detailed description of all classes and methods, see API Reference.

Geodata complies with OGC standards.

SDK versions

iOS SDK packages are available in two versions:

• Full is a full version that allows you to:
  • Add a map to the application and manage it: add markers and geometric shapes, control the camera movement, display layers (for example, traffic), work with map styles, etc.
  • Search for objects in the directory: organizations, buildings, places, and others.
  • Work with the navigator in the application in one of the three modes: free-drive, turn-by-turn, or simulated navigation.
  • Build optimal routes on ​​the map, including routes inside buildings.
  • Use offline data.
• Map is a lightweight version that allows you to:
  • Add a map to the application and manage it: add markers and geometric shapes, control the camera movement, display layers (for example, traffic), work with map styles, etc.
  • Search for objects in the directory: organizations, buildings, places, and others.

Important

You cannot use Full and Map simultaneously. It causes an assembly error.

Getting API keys

To work with the SDK, you need to get a key file dgissdk.key. It allows connecting to 2GIS servers and retrieving the geographical data, as well as using offline data and the navigator. To obtain the key file, fill in the form at dev.2gis.com and specify the appId of the application for which the key is created.

After you receive the key, initialize the SDK. Follow the requirements:

• You can initialize the SDK only once per application. Only one key can be used for each application. Different keys are required in the following cases:
  • If the application is available for different operating systems.
  • If the application has several alternatives for a single OS (for example, one application for the driver and another for the passenger).
  • If different SDK versions are used (Full and Map).
• The appId value of the application must match the app_id value in the key file.
• Changing the key file while the application is running is not supported. Since the key file is selected during SDK initialization, you can give them different names (by default, dgissdk.key is used). To do this, pass a key with a different name via the keySource parameter in DGis.Container.

Some SDK features use search and navigation APIs. Access to these APIs is provided with the SDK key. API usage is paid additionally, depending on the number of sent requests (and in some cases, on the number of received responses). See the list of features and additional APIs below.

Additional APIs

You can check the statistics of API request distribution in the Platform Manager.

Feature	APIs
Creating a search engine (SearchManager class)	Regions API
Getting search results (SearchManager.search method)	Places API Markers API Access to certain information about objects is only available with additional key configuration for an extra fee: see the Object data structure section.
Searching for objects in the directory by ID (SearchManager.searchById method)	Places API Markers API
Building search suggestions (SearchManager.suggest method)	Suggest API
Searching for an optimal route considering traffic jams (TrafficRouter class)	Routing API - all routes except public transport. Public Transport API - public transport routes. Truck Directions API (deprecated) - truck routes. Used only in old keys for the SDK. In new keys, it is provided with the Routing API.
Starting the navigation (NavigationManager.start method): In free-drive mode. In turn-by-turn mode.	Routing API - all routes except public transport. Public Transport API - public transport routes. Truck Directions API (deprecated) - truck routes. Used only in old keys for the SDK. In new keys, it is provided with the Routing API.
Searching for alternative routes (AlternativeRouteSelector class)	Routing API - all routes except public transport. Public Transport API - public transport routes. Truck Directions API (deprecated) - truck routes. Used only in old keys for the SDK. In new keys, it is provided with the Routing API.
Displaying routes on the map (RouteEditorSource class)	Routing API - all routes except public transport. Public Transport API - public transport routes. Truck Directions API (deprecated) - truck routes. Used only in old keys for the SDK. In new keys, it is provided with the Routing API.
Displaying traffic jams on the map (TrafficSource class)	Regions API
Displaying road events (RoadEventSource class)	Regions API

System requirements

• Xcode 14
• iOS 13 and later / iPadOS 13 and later (this SDK uses SwiftUI)

Installation

Swift Package Manager

To install iOS SDK via Swift Package Manager, add a package dependency to your project. See Apple documentation for instructions on installing Swift packages.

To connect SDK, specify the URL depending on the version:

• https://github.com/2gis/mobile-sdk-full-swift-package for the Full SDK version.
• https://github.com/2gis/mobile-sdk-map-swift-package for the Map SDK version.

CocoaPods

To install iOS SDK via CocoaPods, add the DGisMobileSDK dependency.

Use Swift Package Manager versioning, adding the -full or -map postfix, depending on the required SDK version.

You can view the pod specification at one of the following URLs:

• https://github.com/2gis/mobile-sdk-full-swift-package/blob/master/DGisMobileSDK.podspec for the Full SDK version.
• https://github.com/2gis/mobile-sdk-map-swift-package/blob/master/DGisMobileSDK.podspec for the Map SDK version.

Binary artifact

You can download frameworks directly without using package managers. To do this, refer to the repository that contains the package specification for CocoaPods or Swift Package Manager:

• https://github.com/2gis/mobile-sdk-full-swift-package for the Full SDK version.
• https://github.com/2gis/mobile-sdk-map-swift-package for the Map SDK version.

The Package.swift file will contain a URL leading to downloading the SDK archive via a direct link. To navigate through versions, use git tags.

Demo project

You can find a demo app with the source code in the GitHub repository.
