We are running our UI tests through Fastlane on a MacOS machine.  
defaults: &defaults  
macos:  
xcode: “10.2.1”  
environment:  
FL\_OUTPUT\_DIR: output  
shell: /bin/bash --login -o pipefail

Some tests are consistently loosing connection to the simulator.  
Here is a sample log.

```
✓ testPortfolioScreen_InvestAccount (32.446 seconds)
✓ testPortfolioScreen_RetireAccount (32.886 seconds)
AddFundingCardTests
✗ testAddFundingCardScreen_isDisplayed, Lost connection to the application (pid 6391).
✗ testAddFundingCardWithCompleteUser, Lost connection to the application (pid 6404).
✗ testAddFundingCardWithIncompleteUser, Lost connection to the application (pid 6417).
✗ testWhenAddFundingCard_andCashBackEnrollment_getSignUpStatus, Lost connection to the application (pid 6425).
✗ testWhenAddFundingCard_fails_displaysAlert, Lost connection to the application (pid 6434).
AutoFundDeeplinkTests
✓ test_whenAutoFundDeeplinkInvoked_autoFundFeedShown (61.751 seconds)
✓ test_whenEnrolledBankRelinkLoginDeeplinkInvoked (34.248 seconds)

```

We run the same Fastlane job on our local and the tests pass. What is causing this?
