Configuring OS Version

🚀 Cloud Plan required - get started for free at maestro.dev

Android

You can configure your Flows to run on a specific Android OS version (API level) using the android-api-level parameter when running the maestro cloud command:

maestro cloud --android-api-level 30 myapp.apk myflows/

If you're using one of the CI integrations, please refer to the CI documentation for your specific integration:

Using the ios-version parameter (deprecated)

You can configure your Flows to run on a specific iOS major version using the ios-version parameter when running the maestro cloud command:

maestro cloud --ios-version 17 myapp.app myflows/

Maestro will automatically select an appropriate minor version, meaning that if you specify iOS 16 your Flows will for example be run on 16.2. If you happen to specify a minimum deployment target version that is below the selected minor version (for example 16.0), an error message will be surfaced with instructions on how to recover.

Notice this mode is deprecated and will be removed in a future release. Current supported values are 16, 17 and 18. If you use this flag, your tests will always run with an iPhone 11 simulator.

Using a specific iOS minor version & device (recommended)

You can configure your Flows to run on a specific iOS runtime and device using the --device-os and --device-model flags when running the maestro cloud command.

The following values are supported:

• --device-model - iPhone-11, iPhone-16-Pro, iPhone-16, iPad-10th-generation

• --device-os - iOS-16-2, iOS-17-5, iOS-18-2

Please note that not all runtimes are available for all devices. This table covers the available combinations:

Device Model	iOS Version
iPhone-11	iOS-16-2, iOS-17-5, iOS-18-2
iPhone-16-Pro	iOS-18-2
iPhone-16	iOS-18-2
iPad-10th-generation	iOS-16-2, iOS-17-5, iOS-18-2

For example, to run your Flows on iOS 18.2 with an iPhone 16 Pro, you would use:

maestro cloud --device-os iOS-18-2 --device-model iPhone-16-Pro myapp.app myflows/
