config=set
//nexus.veryfi.com/repository/:username=${NPM_USERNAME}
//nexus.veryfi.com/repository/:_password=${NPM_PASSWORD}

• For Android, check if the android/app/build.gradle has the following configuration:

android {
    androidResources {

}

This is necessary to avoid the compresion of the Veryfi machine learning models

• Run your desired platform using: npx expo run:android or npx expo run:ios

In case npx expo run:android does not find the Veryfi's Maven repository, add the following lines to android/app/build.gradle:

repositories {
    maven {
        url "https://nexus.veryfi.com/repository/maven-releases/"
        credentials {
            username = System.getenv("MAVEN_VERYFI_USERNAME")
            password = System.getenv("MAVEN_VERYFI_PASSWORD")
        }
        authentication {
            basic(BasicAuthentication)
        }
    }
}

• In order to be able to enable iOS Lens native localization you need to enable a supported language on the project file:

• Generate localization files for the desired language (for example in storyboard):

• At the end you should have at least 1 file localized for each language that you want to enable localization, see example:
