After upgrading to macOS High Sierra, I'm getting this error when running xcodebuild from the terminal.

}

Code builds and tests pass.

Seems like running the tests from Xcode in all platforms "unlocks" the simulators, and the error no longer appears when running xcodebuild from the command line.

I had the same problem, and the error log clearly identifies the issue, which is a locked iOS device. When you run the compile with the device active and unlocked, the error does not occur.

My problem is this. After searching a lot and not finding a solution, I happened to find it, well for my case.

But before I was intrigued by the publication of a single screen app and few components work, ie in the same environment and mobile and macOS a full app could not publish and the simple all right.

Well absordial but the simple lack of "/" at the end of "RemotePath" was my problem.

Error-> RemotePath = StartUp / Documents

OK-> RemotePath = StartUp / Documents /

I did not have any more problems.
