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, build routes, use the navigator, 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 connect to 2GIS servers, obtain geodata, and enable SDK features, you need to get an access key file:

1. To obtain the dgissdk.key key file, fill in the form at dev.2gis.com and specify:

   • ID of the application (App ID) for which the key will be used. Make sure that the App ID meets the requirements.
   • A list of APIs that require access. The list depends on the required features and the SDK version. For more details, see the API for SDK operation section.

2. Make sure that the key requirements are met.

After you receive the key, initialize the SDK.

API for SDK operation

Depending on the required features, the SDK requires access keys for the maps, search, and navigation APIs. Available features depend on the SDK version: Full or Map.

When you use a key, only access to used APIs is paid based on the number of sent requests (and, in some cases, responses). You can check the statistics of API request distribution in the Platform Manager.

Map (for Full and Map)

For more information on the available options, see the Map instruction.

Displaying routes on the map (RouteEditorSource class)	Directions API - all routes except public transport Public Transport API - public transport routes Truck Directions API - truck routes

Navigation (only for Full)

For more information on the available options, see the Navigation instruction.

Feature	APIs
Starting the navigation (NavigationManager.start() method): in free-drive mode in turn-by-turn mode	Directions API - all routes except public transport Public Transport API - public transport routes Truck Directions API - truck routes
Searching for alternative routes (AlternativeRouteSelector class)	Directions API - all routes except public transport Public Transport API - public transport routes Truck Directions API - truck routes
Displaying road events (RoadEventSource class)	Regions API

Requirements

Key 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 App ID 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.

App ID requirements

An App ID can contain Latin letters (A-Z, a-z), numbers (0-9), periods (.) for segment separation, and hyphens (-).

System requirements

• Xcode 14
• iOS 16 and later / iPadOS 16 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.
