Building with Xcode

Maestro currently supports iOS Simulator builds (.app), AppStore distribution device builds (.ipa) are not currently supported. The easiest way to get an app installed on the simulator is by building and running it from Xcode (make sure that simulator target is selected):

Default build location

If you want to install the .app manually, the file can be found under the Products folder at Xcode Menu: Product -> Show Build Folder in Finder -> Then go to path Products/Debug-iphonesimulator

The .app file can then be installed on the simulator by simple dragging and dropping the file or via Xcode command line tools by running:

xcrun simctl install $DEVICE_UDID /path/to/your/app

Building with Xcode command line tools

To build an app with Xcode command line tools xcrun xcodebuild should be used. Here is an example on how to build Food Truck app for iOS simulator target:

xcrun xcodebuild -scheme 'Food Truck' \
-project 'Food Truck.xcodeproj' \
-configuration Debug \
-sdk 'iphonesimulator' \
-destination 'generic/platform=iOS Simulator' \
-derivedDataPath \

The .app file can be then found under /build folder

Building with Fastlane

If you use fastlane for your automation pipelines the script should look the following way:

      configuration: build_config[:configuration],
      scheme: build_config[:scheme],
      workspace: build_config[:xcode_workspace],
      xcargs: "-quiet -sdk 'iphonesimulator' -destination 'generic/platform=iOS Simulator'",
      derivedDataPath: IOS_DERIVED_DATA_PATH # this will contain the .app which we need later on

Building with Flutter

If you use Flutter to build your app you can create a debug build for simulators using the following command:

flutter build ios --debug --simulator

You can then find your app file in the build/ios/iphonesimulator/ directory.
