To use the Roam SDK, the following things are required:
Get yourself a free . No credit card required.
Create a project and add an iOS app to the project.
You need the SDK_KEY (available in your project settings) to initialize the SDK.
You’re now ready to integrate the SDK into your iOS application.
The Roam iOS SDK requires Xcode 10.0 or later and is compatible with apps targeting iOS version 10 and above.
The Roam Example repository on includes example apps that demonstrate the use of the v3 Roam SDK for iOS.
See Swift's example app in Example/.
To run an example app, clone this repository, add your publishable YOUR-PUBLISHABLE-KEY key in AppDelegate.swift, and build the app.
Make sure the bundle_id is the same as the one registered on our Roam Playground dashboard.
To integrate the Roam SDK, you need a Roam account.
Go to Xcode > File > New Project
Configure the information property list file Info.plist with an XML snippet that contains data about your app. You need to add strings for NSLocationWhenInUseUsageDescription in the Info.plist file to prompt the user during location permissions for foreground location tracking. For background location tracking, you also need to add a string for NSLocationAlwaysUsageDescription and NSLocationAlwaysAndWhenInUseUsageDescription in the same Info.plist file.
Next, you need to enableBackground fetch and Location updates under Project Setting > Capabilities > Background Modes.
There are several ways to integrate the Roam Mobile SDK for iOS into your own project:
Swift Package Manager
CocoaPods
Carthage (Will be added soon)
Dynamic Frameworks
Swift Package Manager is distributed with Xcode. To start adding the AWS SDK to your iOS project, open your project in Xcode and select File > Swift Packages > Add Package Dependency.
You'll see the repository rules for which version of the SDK you want the Swift Package Manager to install. Choose the first rule, Version, and select Up to Next Minor as it will use the latest compatible version of the dependency that can be detected from the main branch, then click Next.
Select roam-ios, then click Finish.
You can always go back and modify which SPM packages are included in your project by opening the Swift Packages tab for your project: Click on the Project file in the Xcode navigator, then click on your project's icon, then select the Swift Packages tab.
Follow the steps below to add the SDK to the project using CocoaPods. Add the below to the Podfile
Then run pod install.
This will add the Roam SDK and its dependencies to your project. The Roam SDK depends on CoreLocation, AWSMobileClient and AWSIoT for fetching locations and its transmission to our servers. The SDK supports iOS 10 and above.
Unzip the file and add the Roam Roam.framework to your Xcode project by dragging the file into your Project Navigator.
Make sure the the added frameworks under Linked Frameworks and Libraries section are selected as Embed & Sign
Roam SDK offers a flexible method of initialization, allowing developers to seamlessly integrate our services into their applications. With our latest update, we've introduced a new initialization approach using property list files (plist). This method provides an effortless way to set up your Roam SDK without the need for additional code.
Using Property List (plist) Initialization:
Optional Parameter: Publish Key
The publishKey parameter in the initialization method is now optional.
If you've added your Roam publish key to your project's .plist file, there's no need to pass the publishKey parameter during initialization.
Configure Your .plist File:
In your info.plist file, declare your Roam publish key as follows:
Replace "$(ROAM_PUBLISH_KEY)" with your actual Roam publish key.
Using XCConfig File (Optional):
Alternatively, you can use an XCConfig file to feed the Roam publish key to the plist file.
In your XCConfig file, add the following line, replacing XXXXXXXXXXXXXX with your Roam publish key:
Initialization Code:
Initialize Roam SDK in your application as follows:
If the publish key is added to the plist, the initialize method can be called without passing any parameters.
By following these steps, you can seamlessly initialize Roam SDK using property list files, simplifying the integration process and saving valuable development time.
Using AppDelegate Initialization:
Add the following code to AppDelegate file. This code imports the SDK and allows the SDK to use other methods.
After import, add the below code underapplication(_:didFinishLaunchingWithOptions:) in your AppDelegate file. The SDK must be initialized before calling any of the other SDK methods using your project's publishable key.
Before you start location tracking, you need to get permission from the user for your application to access locations.
Import CoreLocation at the top of the AppDelegate file.
Make the below class declaration for Location Manager and add this line before the return statement in application(_:didFinishLaunchingWithOptions:) With this line, you ask users to allow the app to access location data both in the background and the foreground.
Use one of the tracking modes while you use the Roam.startTracking method.
To stop the tracking use the below method.
Roam has three default tracking modes along with a custom version. They are different based on the frequency of location updates and battery consumption. The higher the frequency, the higher the battery consumption.

The SDK also provides a custom tracking mode which allows you to customize and build your own tracking mode as per your requirement.

Time between location updates example code:
To listen to location updates, create a class that implements RoamDeleagate and then call Roam.delegate.
Set your RoamDeleagate in a code path that will be initialized and executed in the background. For example, make your AppDelegate implement RoamDeleagate, not a ViewController. AppDelegate will be initialized in the background, whereas a ViewController may not be.
Batch configuration lets you control the number of location data updates being received in the location listener with the desired frequency and window.
As the name suggests, this method sets the configuration parameters.
The networkState indicates the state in which the updates are to be received. It can either be set to online, offline, or both.
The batchCount indicates the size of the location batch.
The batchWindow indicates the time interval for every consecutive update (frequency of updates).
Consider the following call,
Roam.setBatchConfig("networkState.Both", 5 , 60)
The batch count value is the number of location updates sent in a batch. In the above case, the value is set to 5. Ideally, the SDK sends 5 updates per batch and the batch window (in the above case, 60) specifies the number of seconds the SDK waits to receive five location updates.
If the SDK receives 5 location updates in less than 60 seconds, the updates are pushed to the listener. If not, it waits for 60 seconds and pushes the location updates regardless of the batch count value.
Success Callback - We receive a list of BatchReceiveConfig objects.
Example response:
[{"batchCount":5,"batchWindow":10,"networkState":"offline"}, {"batchCount":5,"batchWindow":10,"networkState":"online"}]
Error Callback: We receive a RoamError object in the error callback.
The available details to get from the RoamError object are: error.getMessage() and error.getCode()
The get receiver config method allows the user to get the current batch configuration for the location listener.
The Reset Batch Configuration method allows the user to reset the batch config for the location listener.

If you’re not familiar with using Cocoapods or prefer manual installation, we’ve added a ZIP file to the SDK. Use this link to download the file.
You can do this by selecting the project file in the navigator on the left side of the Xcode window, and then navigating to the Linked Frameworks and Libraries section. From there, click the “+” button to add the Roam framework. You will also want to add the following frameworks from this .
