Actual outcome
Carthage exits with exit code 70 any time a watchOS target is built when using Xcode 10 GM

Expected outcome
Carthage should build the target successfully

The title and log pretty much say it all - anything using watchOS fails. If you use the --platform option to do anything else there's no problem (for libraries that have watchOS as an option). It kinda looks like it's looking for a particular simulator by GUID which isn't there anymore, but that's just a guess.

I found at least one project online where someone pointed this out to them and the response was that it was a Carthage bug.

Anyway I know Xcode 10 isn't final but I thought I'd point it out.

Hi there! I was having the same issue the other day. This seems to have been resolved and merged on master (see https://github.com/Carthage/Carthage/pull/2561).

There hasn't been a Carthage release with this fix yet, so in order to get it, you will need to install Carthage from source:

1. clone the master branch of the repository
2. run make install

So far it's been working great for me and I've been able to bypass the issue.

You can also install via brew with brew install carthage --HEAD

Thanks, the latest code worked great.
