Description:
An compiler error is raised when using my example application:

dex: com.android.dx.cf.code.SimException: ERROR in Swift.SwiftString$UTF8View.GetSequence:()Ljava/lang/Iterable;: return type mismatch: prototype indicates java.lang.Iterable, but encountered type byte[]

Expected Behavior:
The Android application should compile and runnable

Actual Behavior:
The above mentioned error is being raised during compile time

Steps:

  1. Compile mailed project
2

Can we (always) see a test case, please?

Any workarounds?

No idea until someone had a look at what the problem is. But maybe try avoiding looping over Swift.SwiftString.UTF8View.

I am not aware of doing that but I will double check my code

Nope, seems to be a general regression. Any Android project that references swift.jar fails with this :frowning:

Yikes, if this bug is fixed. Any chance you could upload a build with the fix included for me?

will do, but it’s in Carlo’s hands now, so that means not today…
