Accessing storyboard hangs xcode, then throws error below. This happens for newly created project, on newly (re)installed xcode.
I've tried xcrun simctl
commands, there is no device with UDID: 9C08E254-108D-49F6-A1FC-CE43B2F30EB9
.
Not clear which device IBSimDeviceTypeiPad2x
is.
Deleted and recreated all iPad devices in Simulator. iPad 2 is not possible on iOS 11.4
Have already done complete uninstall and reinstall of xcode (including removing ~/Library/Developer / Cache / Application Support
stuff.
Problem persists.
