Unable to load platform at path

Question

When using filemerge to solve HG conflict, I got the following error

FileMerge[18002:707] Unable to load platform at p         


        

Answer 1

And I tried converting iPhoneSimulator.platform/Info.plist from binary to xml, confirmed that Filemerge doesn't produce the error anymore. Then I converted it back to binary, and still, Filemerge is fine.

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform
$ sudo plutil -convert xml1 Info.plist
$ sudo plutil -convert binary1 Info.plist
