Thanks for reporting this issue, how do you use IBAnimatable? Via cocapods? Can you re-install the pod? Can you rebuild the project? If the issue still happens, can you upload a demo project with the issue? Thanks.

I also noticed the tool chain is not right, XcodeDefault.xctoolchain , if you use Swift 2.3 the tool chain should not be default

I use IBAnimatable via CocoaPods, I have clean and re-install it not work.

Am I missing something on setting toolchain?

[JakeLin]

I think it is a general issue not specific for IBANimatable . Is IBAnimatable missing a .swift_version file? I don't know the solution since I can not reproduce this issue. If you can upload a small demo project will help us a lot. Or try to google why Xcode use the wrong tool chain.

I have clean install Xcode from App Store but it still not working, I can't found anything talking about setting Xcode toolchain.

This is demo project.

And I found same issue from another project.

Hi @JakeLin

It works, I did this

post_install do |installer|
    installer.pods_project.targets.each do |target|
        if target.name == 'IBAnimatable'
      target.build_configurations.each do |config|
                config.build_settings['LD_RUNPATH_SEARCH_PATHS'] = ['$(inherited)', '/Applications/Xcode.app/Contents/Developer/Toolchains/Swift_2.3.xctoolchain/usr/lib/swift/iphonesimulator']
      end
    end
end
