Run tests on iOS device

We need to have ios-deploy, libimobiledevice and appium-xcuitest-driver installed:

sudo npm install -g ios-deploy --unsafe-perm=true
brew install libimobiledevice
npm install appium-xcuitest-driver

Check your device id:
idevice_id --list

Build like:

react-native run-ios --device

Here you will also see the path to where your app is being built.

In your wdio.conf capabilities should look like this:

 capabilities: [

      {

        maxInstances: 1,

        platformName: "iOS",

        deviceName: "<DEVICE_NAME>",

        automationName: "XCUITest",

        platformVersion: "11.4",

        udid: "<UDID of your phone>",

        xcodeOrgId: "<TEAM-ID>",

        xcodeSigningId: "iPhone Developer",

        app: path.resolve("./ios/build/Build/Products/Debug-iphoneos/yourappname.app")

      }

    ],

Assuming you have test defined in packages.conf like wdio wdio.conf, you could try now:

npm run test
