injectionforxcode: "Learnt Compile Failed" after Xcode 7.3 for targets with > 128 swift sources

Hi, I am getting this error after updating to Xcode 7.3

injecting_class.o   ***

Learnt compile failed ***   at /Users/Diego/Library/Application Support/Developer/Shared/Xcode/Plug-ins/InjectionPlugin.xcplugin/Contents/Resources/common.pm line 57.  main::error('Learnt compile failed') called at /Users/Diego/Library/Application Support/Developer/Shared/Xcode/Plug-ins/InjectionPlugin.xcplugin/Contents/Resources/injectSource.pl line 349 *** Bundle build failed *** 

There doesn’t seem to be any sign of an error in the stack trace apart from a fairly comprehensive list of files

Program arguments: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift -frontend -c -filelist … list of files

Any clues on this? Thank you very much.

Trying to build my own Xcode toolchain now based of the Swift 3.0.1 with the value set to 512 just to confirm if it works or not.

Thanks for the log. Looks like a compiler crash to me… Actually it’s a problem. Large projects use "-filelist” with 7.3. You’re going to have problems injecting this project unless you can break it a smaller target + framework. I’ll look into it. Can you check if the file referred to in the -filelist argument exists?

Might as well. Apologies for your lost weekend recompiling Swift. This is a much better solution.
