Summary:
I have the Xcode 8 (App Store) version installed at default location (/Applications/Xcode.app). I downloaded the WWDC seed of Xcode 9 while at WWDC. Xcode 9 launches fine. The Simulator application launches fine, but I see an error dialog: "Error returned in reply: Connection invalid". iOS never launches in the Simulator. Simulator requires a force-quit to exit.
I've found two temporary workarounds:
1. Rename the App Store version of Xcode.app to Xcode 8.app
2. Use xcode-select explicitly set my new location (sudo xcode-select -s /Applications/Xcode-beta.app/).
Neither workaround was required when jumping between prior Xcode/Simulator versions. Typically xcode-select was used for command line tools. Actually, that's stated specifically in xcode-select ("This directory
controls which tools are used for the Xcode command line tools"). This is a problem for anyone who will be switching between the two versions regularly over the next few months.
Steps to Reproduce:
Install Xcode 8 from App Store
Install Xcode 9 (WWDC seed)
Launch Xcode 9, then launch Simulator from within Xcode 9
Expected Results:
Xcode 9's simulator functions
(and with above workarounds, ability to use multiple Xcode's is preserved)
Observed Results:
Xcode 9's simulator halts with "Error returned in reply: Connection invalid"
Version:
Xcode 9, WWDC seed, macOS 10.12.5.
