We have noticed a 4X increase in app launch time for UI tests in Xcode 12 compared with Xcode 11. App launch times were typically ~15 seconds and are now approximately ~75 seconds. When I pause the debugger, I can see that it is hanging on XCUIApplication.launch() Is this a known issue? Are others experiencing this issue? Should we be expecting to see this increase? Are there mitigations we can implement to improve the launch time?
