Cannot install brew on Mojave with Xcode 10

I can not install any brew packages on my mac with the following error info.

Installed on my Mac:

Type in brew install xxx. The output is: 

Error: Your Xcode (9.3) is too outdated.
Please update to Xcode 10.0 (or delete it).
Xcode can be updated from
https://developer.apple.com/download/more/

Error: Xcode alone is not sufficient on Mojave.
Install the Command Line Tools:
xcode-select --install

But as I type in xcode-select --install, it says it is not available
Xcode select install error

Paths of two versions of Xcode on my Mac: 

/Applications/Xcode-beta.app
/Applications/Xcode.app

And my config output:
xcode-select -p 

/Applications/Xcode.app/Contents/Developer

brew config

You will need to install both "Xcode 10.0 Beta" from https://developer.apple.com/download/ AND "Command Line Tools (macOS 10.14) for Xcode 10 Beta" from

https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_macOS_10.14_for_Xcode_10/Command_Line_Tools_macOS_10.14_for_Xcode_10.dmg

Update contributed by other comments, after you installed "Command Line Tools", you will also need to execute the following command in your terminal.

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

Beginning in 10.14, a new step is required to create the header files in /usr/include:

Install /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

After installing CLT, you can ask CLT to add header files to /usr/include, then homebrew will appropriate detect the Command Line Tools.

installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

confirm that Command Line Tools for 10.14 won't create /usr/include/ folder that makes brew install script insist to re-download and install CL.

download the script, and manual removing checking works fine. (be aware it should be false instead of true.

def should_install_command_line_tools?
  return **false**
end

I was able to install Homebrew on Mojave by manually downloading the command line tools here: https://developer.apple.com/download/more/

Modify the Homebrew install script here: https://raw.githubusercontent.com/Homebrew/install/master/install

By replacing:

def should_install_command_line_tools?
  return false if force_curl?
  return false if macos_version < "10.9"
  !File.exist?("/Library/Developer/CommandLineTools/usr/bin/git") ||
  !File.exist?("/usr/include/iconv.h")
end

With this:

def should_install_command_line_tools?
  return true
end

Then just execute the script.

This is a little hacky, but it worked for me and could help someone out in the beta period.

After installing Xcode 10 Beta and Command Line Tools (macOS 10.14) for Xcode 10 Beta, I also changed the path for xcode-select to use the newly installed command line tools with:

sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer

At this time, Brew is not supporting macOS Mojave Beta.

(Type brew doctor to confirm that they are not accepting issues for Mojave yet)
