I have installed Appium 1.17.0 for iOS 13.5.1  
Xcode 11.5, macOS 10.15.5

**I am getting the below in my iOSDriver exception:**

_org.openqa.selenium.WebDriverException: It is impossible to create a new session because ‘createSession’ which takes HttpClient, InputStream and long was not found or it is not accessible_

_Driver info: driver.version: IOSDriver_

**Console logs:**

Any suggestions in resolving the issue will be helpful.

4. Deleted the derivedData folder
5. Opened Xcode and configured WDA
6. Cleaned build folder. Build WDA
7. Build WDA with Generic iOS device

No luck. Same issue!!!

</div>

after you build WDA in xCode in “Users/UserName/Library/Developer/Xcode/DerivedData/WebDriverAgent-ciegwgvxzxdrqthilmrmczmqvrgu/Build/Products/Debug-iphoneos” you see “WebDriverAgentRunner-Runner.app” is it?

This means you did not build it.

Once again in xCode open wda. Set target webdriverrunner for general ios device and push build button.
