I'm facing this issue intermittently since using Xcode 16 beta 4 on macOS 14.5 when starting xcodebuild build with -destination option.

20:56:07 ▸ xcodebuild: error: Unable to find a device matching the provided destination specifier:
20:56:07 ▸ { platform:iOS Simulator, OS:15.4, name:iPhone 13 Pro }
20:56:07 ▸ The requested device could not be found because multiple devices matched the request. (

This mac is mac mini 2023 M2 Pro 32GB memory, running with multiple simruntimes installed:

I've never seen this kind of simulator missing error.

Nor installing any duplicate runtime(s) on the same machine because it will show error message like 'unable to use this runtime' on xcrun simctl runtime list.

Could anyone give me a tip of avoiding this kind of error?

Adding information from xcrun simctl list on the same machine and this would show clearly that no duplications are seen.

You have two phones named "iPhone 13 Pro" configured for iOS 15.4.

The important output to look at is simctl list devices.

Based on the output, I'm guessing you ran sudo simctl list devices for your followup comment as the UDIDs do not match the original post.

You should almost never use sudo with xcrun simctl as it probably isn't doing what you want it to ;)

Here's the fail log of xcodebuild with -destination flag, and without sudo upfront:

Why do the simulator devices show up doubled? I executed job only once but seems like CoreSimulator starts up twice. I know this occurs intermittently but the problem shows up too frequently.
