The Maps App for iOS shows how a robust application can be built around the ArcGIS Platform using the ArcGIS Runtime SDK for iOS and Swift. It demonstrates best practices around some simple but key functionality of the ArcGIS Runtime. You can use the Maps App as is, or extend it to meet your specific needs.

• Place Search
• Geocode addresses
• Reverse Geocode
• Turn-by-turn Directions
• Dynamically switch basemaps
• Open Web Maps
• Work with ArcGIS Online or an on-premise ArcGIS Portal
• OAuth authentication

The project also demonstrates some patterns for building real-world apps around the ArcGIS Runtime SDK.

• Defining a modular, decoupled UI that operates alongside a map view
• Asynchronous service and UI coding patterns
• Internal application communication patterns

You will need Xcode and the ArcGIS Runtime SDK (v100.1 or later) installed locally.

Fork the Maps App repo

Once you have forked the repo, you can make a clone and open maps-app-ios.xcodeproj in Xcode.

1. Clone the Maps App
2. cd into the maps-app-ios folder
3. Make your changes and create a pull request

If you make changes in the fork and would like to sync those changes with the upstream repository, you must first configure the remote. This will be required when you have created local branches and would like to make a pull request to your upstream branch.

1. In the Terminal (for Mac users) or command prompt (for Windows and Linux users) type git remote -v to list the current configured remote repo for your fork.
2. git remote add upstream https://github.com/Esri/maps-app-ios.git to specify new remote upstream repository that will be synced with the fork. You can type git remote -v to verify the new upstream.

If there are changes made in the Original repository, you can sync the fork to keep it updated with upstream repository.

1. In the terminal, change the current working directory to your local project
2. Type git fetch upstream to fetch the commits from the upstream repository
3. git checkout master to checkout your fork's local master branch.
4. git merge upstream/master to sync your local master branch with upstream/master. Note: Your local changes will be retained and your fork's master branch will be in sync with the upstream repository.

The app can be run as is, but it's recommended you do some configuration to set up OAuth to be relevant to your users (certainly it should not be deployed without these changes):

1. Register an ArcGIS Portal Application.
2. Configure the Maps App project to reference that application.
3. License the app to remove the Developer Mode watermark.

For OAuth configuration, create a new Application in your ArcGIS Portal to obtain a Client ID and configure a Redirect URL. The Client ID configures the ArcGIS Runtime to show your users, during the log in process, that the application was built by you and can be trusted. The Redirect URL configures the OAuth process to then return to your app once authentication is complete.

1. Log in to https://developers.arcgis.com with either your ArcGIS Organizational Account or an ArcGIS Developer Account.
2. Register a new Application.
3. In the Authentication tab, note the Client ID and add a Redirect URL, e.g. my-maps-app://auth. We will use this URL in the Configuring the project section below.

Configure Redirect URL

1. Open the project in Xcode and browse to the maps-app-ios target's Info panel and expand the AGSConfiguration dictionary (see steps 1-4 in the screenshot below).
2. Set the AppURLScheme value to match the Redirect URL scheme (the part before the ://, e.g. my-maps-app) configured in "Register an Application" above. Note how the AppURLScheme and AuthURLPath combine to construct the Redirect URL.
3. Expand the URL Types section and modify the existing entry.
   1. The Identifier doesn't matter, but should be unique (e.g. com.my-org.my-maps-app).
   2. The URL Scheme should match the Redirect URL scheme (the part before the ://, e.g. my-maps-app) configured in "Register an Application" above.

Configure Client ID

1. In the Navigator pane, click to expand the group maps-app-ios/Maps App to reveal a file named AppSettings.swift.
2. Within AppSettings.swift set the value of the static variable clientID to the application's Client ID noted above.

Remove the Licensed for Developer Use Only watermark on the map view by setting the Runtime License Key.

This step is optional during development, but required for deployment.

1. Get your Runtime Lite License Key by clicking the Show my ArcGIS Runtime Lite license key at the top-right of the Licensing Your ArcGIS Runtime App page (you must be logged in).
2. Open the project in Xcode and navigate to AppSettings.swift, the same file used to configure your applications client id.
3. Set the value of the static variable licenseKey to the value from step 1.

• Xcode
• ArcGIS Runtime SDK for iOS
• For directions and to browse Web Maps you will also need an ArcGIS Online Organizational account or an ArcGIS Online Developer account.

Note: Starting from the 100.8 release, the ArcGIS Runtime SDK for iOS uses Apple's Metal framework to render maps and scenes. In order to run your app in a simulator you must be developing on macOS Catalina, using Xcode 11, and simulating iOS 13.
