[segiddins]

Please open a new issue with the contents of a Podfile that I can use to reproduce this.

[stepanhruda]

Will do, sorry.

[aufflick]

@stepanhruda did you create an issue? I'm seeing the same, but on a podfile I can't upload so hoping not to have to reduce the bug if you have created a ticket already.

[aufflick]

FWIW v0.37 doesn't have this issue.

[carolanitz]

We're also having the same issue and decided to go back to v0.37 as well. We'd like to have a reference to the new issue created by @stepanhruda though :)

[neonichu]

There's no need to downgrade because of this, one can simply opt-out of deterministic UUIDs for now, see https://github.com/CocoaPods/CocoaPods/blob/master/CHANGELOG.md#enhancements-1

In case you can share anything to reproduce the issue, that'd be greatly appreciated :)

[carolanitz]

thanks we'll try that ! Well maybe we can show you stuff one on one but I can't post our podfile online ;)

I am getting this issue with the following Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

  pod 'Fabric'

Did you ever get a resolution to the error in that podfile @DougBanksPersonal ?

[caraballoj]

add 'install! 'cocoapods', :deterministic_uuids => false, :integrate_targets => false' to the root of the pod file, then do pod update. This worked for me.

[acalism]

It's caused by duplicate files in different directories.
Sometimes Xcode might make mistake and duplicate files when you move files to another directory.

My solution to find these duplicate files,

1. copy error messages to a text file named such as duplicateUUIDs.txt
2. get sorted file names and output duplicated items
   grep -E '[a-zA-Z+]+\.(h|m|swift)' -o duplicateUUIDs.txt | sort | uniq -d
3. find them in your pod source directory and delete unnecessary files.

Another method to find duplicate files
find . -path ./.git -prune -o -type f -exec basename {} + | sort | uniq -d
where -path ./.git -prune -o means to exclude .git directory when finding
