Appium gets stuck before running test

iOS, simulator
Appium version 1.7.1
xcode version 9.0.1
Language: Java

I have a problem that started occurring after update to new (1.7.0) Appium. When I start test form Intellij, app will start on simulator and then Appium gets stuck on this line :
[JSONWP Proxy] Proxying [POST /session] to [POST http://localhost:8100/session] with body: {"desiredCapabilities":{"bundleId":"com.****.*****","arguments":[],"environment":{},"shouldWaitForQuiescence":true,"shouldUseTestManagerForVisibilityDetection":false,"maxTypingFrequency":60,"shouldUseSingletonTestManager":true}}

Sometimes the test will start after few minutes, but most of the times nothing happens for very long time so I just quit everything. Here are the full logs

I am having the same issue after upgrading Appium to 1.7.1.

Reported it here but didn’t get any solution -

Anyone has any idea about the cause/fix?

Maybe they will look into it when you log issues separately.

For now, I am only interested in the one you have reported in this thread.

The solution is to set useNewWDA capability to true.

Try setting waitForQuiescence to false.

Initial tests show adding following capability resolves the issue irrespective of whether useNewWDA is true or false:

 capabilities.setCapability("waitForQuiescence", false);
