Quit your Simulator.app in advance. 1. Launch safaridriver /Applications/Safari\ Technology\ Preview.app/Contents/MacOS/safaridriver --port 4444 2. curl by another terminal ``` curl -X POST \ http://localhost:4444/session \ -H 'Content-Type: application/json' \ -d '{ "capabilities": { "alwaysMatch": { "platformName": "ios", "browserName": "safari", "safari:useSimulator": true } } }' ``` ## Environment - iOS version: iOS13.1 - 13.3 (Sorry, I couldn't control it) - host machine version: 10.14.6 - safaridriver version: Included with Safari Technology Preview (Release 97, 14609.1.11.4) ## Note - There is some tendency as the following. 1. After launching a simulator by building an iphone app on xcode, it will be successful to create a webdriver session in most cases. 2. When you launch a simulator by Simulator.app or W3C New Session API, it will fail to create a webdriver session in most cases.
