“iOS 17.0.simruntime” cannot be opened because the developer cannot be verified

Question

I just downloaded the iOS 17 runtime, but after copying it into the destination, this popup opens and the Xcode could not use the simulator as expected:

_{Downloaded from the Apple Developer site}

How can I fix this?

Answer 1

Try this:

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

Answer 2

It is possible to call simctl on the downloaded .dmg to add the simulator runtime manually. That is a safer workflow that also performs code signing verification. The command would be:

xcrun simctl runtime add <pathTo/platform_simulator_runtime.dmg>

Manually copying the .simruntime into the intended location for installation is an unsupported workflow.
