Hi, trying to build kotlin multiplatform project with version 1.3.60-dev-2303 and getting this error during the IOS build.
Copy code
> Task :linkMyLibReleaseFrameworkIos
e: Compilation failed: Lowering DCEPhase: phases [Devirtualization] are required, but not satisfied
I'm using these options
Copy code
freeCompilerArgs += "-Xdisable-phases=Devirtualization,BuildDFG"
Without these options build goes well. On the previous version 1.3.41 these options work well

you probably need to disable DCE phase as well
Another option is to remove all those hacks and check if it works for you now.

I've got
Copy code
Execution failed for task ':compileKotlinIos'.
> Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_201.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1
using this
Copy code
freeCompilerArgs += "-Xdisable-phases=Devirtualization,BuildDFG,DCE"
These hacks are very useful, it's helping us to debug IOS application

Use 
DCEPhase
, and maybe makes sense to report bug with minimal reproducer, so that we could fix it in 1.3.60.

Disabling DCEPhase worked, thanks!
