FAQ

iOS Runs on Debug, Crashes on Release Build

This happens due to Xcode 13 introducing a new option to their App Store Distribution Options:

"Manage Version and Build Number" (see image below)

If checked, this option changes the version and build number of all content of your app to the overall application version, including third-party frameworks. This option is enabled by default. Please make sure to disable this option when archiving / exporting your application to the App Store. Otherwise, the Jumio SDK version check, which ensures all bundled frameworks are up to date, will fail.

Xcode13 Issue

Alternatively, it is also possible to set the key manageAppVersionAndBuildNumber in the exportOptions.plist to false:

<key>manageAppVersionAndBuildNumber</key>
<false/>

App Crash at Launch for iOS

If iOS application crashes immediately after launch and without additional information, but works fine for Android, please make sure to the following lines have been added to your podfile:

post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
          config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
      end
    end
end

Please refer to iOS guide for more details.

iOS Localization

After installing Cocoapods, please localize your iOS application using the languages provided at the following path:
ios -> Pods -> Jumio -> Localizations -> xx.lproj

Localization

iProov String Keys

Please note that as of 3.8.0. the following keys have been added to the SDK:

  • "IProov_IntroFlash"
  • "IProov_IntroLa"
  • "IProov_PromptLivenessAlignFace"
  • "IProov_PromptLivenessNoTarget"
  • "IProov_PromptLivenessScanCompleted"
  • "IProov_PromptTooClose"
  • "IProov_PromptTooFar"

Make sure your podfile is up to date and that new pod versions are installed properly so your Localizable files include new strings. For more information, please refer to our Changelog and Transition Guide.

Empty Country List for Android Release Build

If country list is empty for the Android release build, please make sure your app has the proper internet permissions. Without a working network connection, countries won't load in and the list will stay empty.

If necessary, please add android.permission.INTERNET permission to your AndroidManifest.xml file.

The standard Flutter template will not include this tag automatically, but still allows Internet access during development to enable communication between Flutter tools and a running app. For more information, please refer to the official Flutter documentation.
