Applications generated by Symplr are built using React Native and require specific versions of supporting development tools to build and run successfully. This page provides the approved software toolchain versions for each supported React Native release. Before building or running a generated application, ensure that the required versions of Node.js, Java, Android SDK components, Xcode, Ruby, and CocoaPods are installed. Using unsupported tool versions may result in dependency installation failures, Android build failures, iOS build failures, simulator or emulator launch issues, and runtime compatibility issues.

​
When to Use This Page

Use this page when:
  • Setting up a local development environment
  • Running a generated application locally
  • Troubleshooting Android build failures
  • Troubleshooting iOS build failures
  • Verifying software compatibility requirements
  • Preparing a development workstation for Symplr-generated applications

​
Currently Supported React Native Versions

Symplr currently generates applications using the following React Native versions: Any other React Native version is currently outside the supported scope.

​
Determine the React Native Version

To determine which React Native version your application uses:
  1. Open the downloaded application package.
  2. Locate the package.json file.
  3. Find the react-native dependency.
Example:
Use the matching compatibility information listed below for your application’s React Native version.

​
Software Tool Compatibility Matrix

The following installation methods are recommended when preparing a local development environment.

​
Android Development Requirements

For Android application development, ensure that:
  • Android Studio is installed
  • Android SDK Platform is installed for the required API level
  • JDK 17 is configured correctly
  • Android SDK Build Tools are available
  • Android Emulator images are installed when emulator testing is required

​
iOS Development Requirements

For iOS application development, ensure that:
  • Xcode 26.1.1 is installed
  • CocoaPods is installed
  • Ruby 3.2 or later is installed
  • iOS Simulator components are available
  • Apple development requirements are satisfied

​
Common Compatibility Issues

Using unsupported software versions may result in:
  • Dependency installation failures
  • Android build failures
  • iOS build failures
  • Android Emulator launch issues
  • iOS Simulator launch issues
  • CocoaPods installation failures
  • Gradle synchronization failures
  • Runtime compatibility issues
If build failures occur, verify that all installed tools match the versions listed in the compatibility matrix. For additional setup and execution guidance, see:
