Unable to run WebDriverAgent via fbsimctl on real devices

Hi,
I have multiple Macs with multiple idevices available to me to run WebDriverAgent via the fbsimctl framework. After custom installing it by cloning the FBSimulatorControl repo, brew installing carthage, and running the ./build.sh fbsimctl build output command. I can successfully run the fbsimctl command line tool. Likewise, after building WebdriverAgent with the following command, I'm able to use the xctest output as an argument for fbsimctl:

security unlock-keychain -p $my_password ~/Library/Keychains/login.keychain
xcodebuild -project WebDriverAgent.xcodeproj -scheme WebDriverAgentRunner build

However, after booting a simulator and re-running the unlock-keychain command, I get the following error when trying to run com.apple.mobilesafari:

With real devices, I get an even more basic issue at the level of an error in Swift:

During neither of these errors am I able to access the WDA server at localhost:8090. Why might these be happening?

EDIT: I figured out the emulator devices issue. By passing in something into the destination of the xcodebuild command (like one of the idevice's udids), the WebDriverAgent build began to work:

jenkins$ xcodebuild -project WebDriverAgent.xcodeproj            -scheme WebDriverAgentRunner      -destination "id=f6d0770375288a9dc49c70746221ddc0bcb2fca8"      build

Output from fbsimctl:

However, real devices still encounter that error.

any update or any plan to support launching WDA on real devices?

WDA can run on real devices just fine, such as through xcodebuild with the test flag at the end. My issue is running WDA via fbsimctl on real devices.

You can look at #345

We just released idb. which has support for both simulators and devies. We recommend switching over. As part of our renewed commitment to this repo we are cleaning up old issues and will be monitoring and reviewing more closely from now on. if you still think this issue is relevant feel free to reopen
