On Xcode 10 with simulators iOS 11.4 and iOS 12
when creating a WebDriver session with desired capability shouldWaitForQuiescence = false
(or if not setting the capability, it defaults to false(in objc code - NO))
then it takes approximately one minute at application launch - i.e. before the method FBApplication.launch returns.

Example of desired capabilities

{
  "bundleId": "MyCoolApp",
  "shouldWaitForQuiescence": false // or 'shouldWaitForQuiescence' not present
}

When setting shouldWaitForQuiescence = true or effectively equal - commenting out the whole if block in FBApplication.launch
then the FBApplication.launch returns within 5-6 seconds.

Below is the part of code in FBApplication.m where the method [super launch]; (XCTest framework method) meditates for one minute (but only in case if the addObserver:self was executed).

- (void)launch
{
  if (!self.fb_shouldWaitForQuiescence) {
    [self.fb_appImpl addObserver:self forKeyPath:FBStringify(XCUIApplicationImpl, currentProcess) options:(NSKeyValueObservingOptions)(NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew) context:nil];
    self.fb_isObservingAppImplCurrentProcess = YES;
  }
  [super launch];
  [FBApplication fb_registerApplication:self withProcessID:self.processID];
}

As a workaround - creating WebDriver session with capabilities

{
  "bundleId": "MyCoolApp",
  "shouldWaitForQuiescence": true
}

If I remember correctly, this behaviour is observed since Xcode 10 beta 5

I am also seeing this issue in the version of WebDriverAgent packaged with Appium 1.9.0. In Appium 1.9.1 waitForQuiescence=false is broken. Stack trace:

@jamesvanhorn this is a bit different bug. the one that you've posted should be fixed by appium#119

Should the desired capability for Appium be

waitForQuiescence
// or
shouldWaitForQuiescence

?

How is it going on? Is there someone can handle this?

same issue with xcode 10.1 and iOS 12.1.1 and appium 1.10.0 in realdevice.
it takes exactly one minute to launch the test once app is opened or it just keeps opening the app again and again

Hey guys i think i found a hacky solution to run automation on iOS 12> in real devices
i copied ios 12sdk in xcode10 to xcode 9
used appium 1.10.0
in the desired capabilities set platformVersion to 11.4 even though its >12
set xcode to version 9 using sudo xcode-select -switch /Applications/Xcode.app/
doing all these i am able to run automation in ios 12.1.1 in realdevice and appium 1.10.0 using xcode9

Does anyone have another solution or is @jswaroop downgrade to XCode 9 the way to go?
