Developer tools could not be found.

Update on 20161112:

download ApplicationLoader_3.1.dmg

and use it to upload, in the fail log, it successfully recorgnizes the XCode.app.

update on 20161111:

uninstalled XCode 7 and deleted XCode 8.1

I even deleted com.apple.dt.Xcode.plist in the preferences folder, both system and user's

Then reboot and install from Mac App Store.

Anyhow it does not work, the path in xcode-info is not valid yet, error 21023.

--------- original description ----------

Recently I failed to upload binaries to AppStore/Testflight.

My Environment: macOS 10.12.1 + XCode 8.1 + Application Loader 3.6

Use organizer to upload directly: failure

Export ipa then upload by Application Loader 3.6: failure. and I got log which says in summary:

1 package(s) were not uploaded because they had problems:

/var/folders/10/knwm1bfn4q9g8l_rsr2697fw0000gq/T/E31A5B4E-CC42-4165-8748-CA3B00992787/532081550.itmsp - Error Messages:

ERROR ITMS-90168: "The binary you uploaded was invalid."

Check some threads in this forum and stackoverflow, yet can not solve the problem.

While I check the log, there is a strange error inside:

the xcode path is strange and caused an -21023 error

<key>search-method-string</key>

  <key>code</key>
  <integer>-21023</integer>
  <key>message</key>
  <string>Developer tools could not be found. Be sure Xcode is installed and try again.</string>

But, I just install XCode 8.1 to

xcode-select -p 
/Applications/Xcode.app/Contents/Developer

and a copy of XCode 7.3 in

/Applications/Xcode7.app/Contents/Developer

The problem lasts for a time. Before I upgrade to macOS 10.12, When I failed to upload binary with XCode 7, I can use the Application Loader 3.0 to upload.

But now I have to find another Mac to do the job.

So, could anyone be help?

Thanks in advance.
