Set Up Your Environment

Last updated:

Now that you have taken care of all the preliminary issues, we can start building the app. Throughout this guide, you will continously modify this project to extend its functionality to cover a number of basic features.

Known Issues

  1. Developing on the new Arm-based Apple Silicon (M1) Macs requires building and running on a physical iOS device or using an iOS simulator running iOS 13.7, e.g. iPhone 11. This is a temporary limitation in Google Maps SDK for iOS, and as such also a limitation in MapsIndoors, due to the dependency to Google Maps.

Create an Xcode Project

We recommend using Xcode for following along, for this guide we will be using Xcode 13.0. Note that an iOS mobile device is not required, as Xcode allows the use of a simulator. Furthermore, in accordance with the known issues with Google Maps and Arm-based Apple Silicon (M1) Macs, we will be using an iPhone 11 (iOS 13.7) simulator throughout.

We start off by creating an Xcode project using the App template,

Xcode Template

For the project settings, you can call it anything you like, however ensure the following settings are set to follow along easier,

  • Interface: Storyboard
  • Language: Swift

Project Options

You should now have a project folder with the following files,

Project Folder

For the sake of simplicity we will only be operating on these pre-generated files throughout the guide.

Installing the MapsIndoors SDK

MapsIndoors can either be installed using CocoaPods (Getting Started with CocoaPods) or through a manual installation.

Installing MapsIndoors Using CocoaPods

From MapsIndoors SDK version 3.32.0 and upwards, in order for CocoaPods to fetch the SDK properly it is neccessary to install git-lfs (Install Guide).

  1. Create an empty text file named Podfile in your project directory (same folder as your .xcodeproj).

  2. Add your dependecies to the Podfile as followed (replace YOUR_APPLICATION_TARGET_NAME_HERE with your project name),

    source ''

    platform :ios, '15.0'


    pod 'MapsIndoors', '~>3.34.0'

  3. Save the Podfile and open a terminal in the directory of the project. cd \<path-to-project>

  4. Run pod install in the terminal.

  5. Close Xcode.

  6. From this time onwards, use the .xcworkspace file to open the project from now on.

Install MapsIndoors Manually

Since MapsIndoors is dependent on Google Maps iOS SDK, you must also install this SDK, either manually, using Carthage or using CocoaPods. You should use Google Maps iOS version 4.2.0 since MapsIndoors >=3.30.0 is linked against this version.

When the Google Maps installation is completed, go through these steps to install MapsIndoors:

  • Download and unzip the latest MapsIndoors.xcframework.
  • Drag and drop the framework into your XCode project. In the dialog that pops up, choose “Copy items if needed” and make sure the framework is added to the correct target.
  • From XCode, right click the imported framework and click "Show in Finder".
  • In Finder, Locate ios-arm64 > MapsIndoors.framework > Resources > MapsIndoors.bundle, and drag the bundle into your XCode project as well. This time, make sure to uncheck “Copy items if needed”.

Adding API Credentials

Open back up the project and navigate to the file AppDelegate.swift.

  1. Add the following import statements to the top of the file,

    import GoogleMaps  
    import MapsIndoors
  2. Insert the following into the application(_:didFinishLaunchingWithOptions:) method,

GMSServices.provideAPIKey(      "YOUR_GOOGLE_API_KEY")  
MapsIndoors.provideAPIKey( "YOUR_MAPSINDOORS_API_KEY",

Finally, remember to replace YOUR_GOOGLE_API_KEY with your Google API key and YOUR_MAPSINDOORS_API_KEY with your MapsIndoors API demo key (d876ff0e60bb430b8fabb145).
