Survicate iOS SDK
The iOS SDK is distributed in a binary version and developed using Swift 5.7. For apps downloaded from the App Store, the Survicate iOS SDK adds ~ 7.2MB to your uncompressed app size on device. Note that the SDK features a Time To Live (TTL) mechanism of 60 seconds. This means any modifications made to your survey will be reflected on your respondents' devices after a delay of up to 60 seconds."
- Using Survicate Mobile SDK requires an account at survicate.com. You can create your account here for free, or become invited to your company account by one of your colleagues.
- Xcode 14 is required to to build iOS SDK.
- Respondent's device running iOS 12 or above.
There are three ways to install the Survicate Mobile SDK in the iOS applications:
The recommended installation method.
- Once your iOS application project is ready, open it in the Xcode and select your project’s Package Dependencies tab
- Copy the Survicate SDK Swift package repository URL
https://github.com/Survicate/survicate-ios-sdkinto the search field
- Under the Dependency Rule, select the version of your preference.
- After the package download completes, select Add Package.
Survicate SDK should now be listed under Swift Package Dependencies in the Xcode Project Navigator.
Define pod in your
Podfile and run
- Download and extract the Survicate for iOS
- Drag Survicate.framework into your project. Make sure "Copy items if needed" is selected and click Finish.
- In the target settings for your app, set the Survicate.framework to “Embed & Sign”. You'll find it in the “Frameworks, Libraries, and Embedded Content” section of the “General” tab.
The following configuration will require a Workspace Key. You can get your workspace key in the Access Keys section of the Survicate panel.
- Add workspace key to your
SurvicateDictionary. This is how your
Info.plistfile should look like:
- Initialize the SDK using the
initializemethod. Choose an initialization method described below based on whether your project utilizes 'AppDelegate' class.
Make sure that
import Survicate line exists in all classes where you call SDK methods.
Survicate iOS SDK can be used in SwiftUI projects. If your SwiftUI project doesn't use the
AppDelegate class, the initialization of the Survicate Mobile SDK can be done in the constructor of the main application class:
As an alternative to the main way of specifying the Workspace Key, you can also use the
setWorkspaceKey()method overrides the Workspace Key defined in the configuration.
setWorkspaceKey()method must be used before
init()method is called.
Survicate allows you to launch precisely targeted surveys inside your app. In Survicate Panel, you'll be able to define conditions that your users have to meet for the surveys to appear. Users matching conditions defined in the Survicate panel will see the survey automatically. Here's a list of conditions you can use to target your surveys:
- Name of the screen that a user currently sees
- Any application event
- User attributes and identities
- Device language
- Operating system
Make sure to list all the screens and events described in your application. Once you got this covered, you or any person responsible for creating and managing surveys will be able to trigger surveys from the Survicate panel with no need for you to update the application.
Warning The SDK utilizes UserDefaults to store information used by the targeting engine described in this section. Clearing UserDefaults will cause the targeting system to malfunction; f.e. by showing the same survey twice to a single user.
A survey can appear when a user is viewing a specific screen. For example, a survey can be triggered to show up on the application's home screen after a user spends more than ten seconds there. To achieve that, you need to send information to Survicate about the user entering and leaving a screen.
Screen name is case sensitive. If there's any discrepancy between what's declared in the ‘Screens’ tab of the Target section in the Survicate panel and the application code, the survey will not appear.
You can log custom user events throughout your application. They can later be used in the Survicate panel to trigger your surveys. Your survey will instantly after an event occurs in your app.
Event name is case sensitive. If there is any discrepancy between what's declared in the ‘Triggers’ tab of the Target section in the Survicate panel and the application code, the survey will not appear.
You can pass user attributes to Survicate as an additional layer of information about your users. Attributes can be used to:
- Identify respondents (by default survey responses are anonymous)
- Trigger surveys
- Filter survey results
Bear in mind that user attributes are cached, you only have to provide them once, e.g. when user logs in, not after each
init(). You can also change their values at any time (which may potentially trigger showing the survey).
If you need to test surveys on your device,
reset() method might be helpful. This method will reset all user data stored on your device (survey views, attributes, and information about answered surveys for the targeting engine).
SDK allows you to utilize event listeners. You may find them useful to trigger actions in your application based on actions performed by respondents. Here's a list of events you can subscribe to:
- survey_displayed - occurs when survey is loaded and appears in the User Interface
- question_answered - occurs after a question is answered ( Survicate stores incomplete survey submissions )
- survey_closed - occurs when a user closes the survey using the close button
- survey_completed - occurs when a user finishes the survey.
SurvicateAnswer object properties
|id||integer||Answer ID. Applicable only for type = ['single', 'smiley_scale', 'dropdown_list', 'rating'].|
|ids||integer||Array of answer IDs. Applicable only for type = ['multiple'].|
|value||string||Context value of the answer. Applicable only for type = ['text', 'nps', 'date'].|
Note: We currently support passing the
value properties only for the cases enlisted in the table above. You can expect to stumble upon answer objects that consist only of the

- Scale labels can now be displayed below the smiley scale question
Survey settings Time to Live(TTL) mechanism on respondent's device. The mechanism ensures that the survey settings are up to date on the respondent's side. If the current version of survey settings is older than 60 minutes, the survey configuration is checked for updates.
setWorkspaceKey()allows to specify Survicate workspace key from code.
Locales used by SDK were improved to resolve issue related to warning WARNING ITMS-90176 appearing during upload the app using SDK to the AppStore
We restored the minimum iOS version required for the SDK to work to 10.0.
Survicate iOS SDK is now distributed as an XCFramework binary, making the SDK compatible with Swift 5.x. As a result, the main class of Survicate Mobile SDK had to be renamed.
The version 1.5.3 of the Survicate iOS SDK introduces support for binary framework, which causes a minor backward compatibility break. Until the version 1.5.3 the main SDK class was called
Survicate, in the version 1.5.3 that class was renamed to
SurvicateSdk. The change was introduced to make it possible to distribute Survicate Mobile SDK as the XCFramework binary.
