How do I avoid XCode 10.1 installation errors?

I have an iMac that can't run MacOS later than High Sierra, so it's running 10.13.6. A year or so ago I was using Xcode 9 (can't remember what version) to develop a Mac app and now I want to do iOS development. I read that I can use Xcode 10.1 on my machine, so I updated my developer credentials and certificates, and then downloaded the Xcode 10.1 (it's big!!) and installed it after a restart of my iMac. So far so good, but when launched it asks for permission to install additional components. I agree, but then get this

"An unknown error occurred. See the install log for more details."

I looked at the install log but I can't understand it. I include it below. What did I do wrong? Perhaps some old stuff is inhibiting the installation, but what and where? Can anyone help?

Answering my own question, I found out that within the contents of the Xcode package, there's a folder called "packages" which contained in my case three .pkg files. I trashed them and tried again and everything worked! Presumably the old packages date from the original issue date of Xcode 10.1. With these ones absent, Xcode included more recent versions. Obscure, but at least it worked.

Had same problem. The packages MobileDevice.pkg, MobileDeviceDevelopment.pkg and XcodeSystemResources.pkg in Contents/Resources/Packages dated from 18 October 2018. Indeed, when trashed, Xcode will start.

However, even better, when I downloaded today (13 April 2020) Xcode 10.1, it had packages dated 5 October 2019. This version of Xcode just started fine and installed the additional components without issues.
