This should not be necessary, because the isIos variable should be true for robovm-ios and moe-ios.
Maybe moe-ios is detected as android, since it's based on Android ART.

Yes, it is recognized as Android. In MOE 1.3.0-beta-1, we changed the behavior of System.loadLibrary to be compliant with VM specs, which introduced this issue. Would you like us to change the isIos variable instead of creating an isMoe?

Would be better to fix that moe is recognized as Android, so changing https://github.com/libgdx/libgdx/pull/4519/files#diff-02298d26f3a99802c7af1ef20425088fL51 to

// MOE is recognized as Android, since it's based on ART, so check that it's really Android
if (vm != null && vm.contains("Android Runtime") && !isMOE) {

and changing the check isIos || isMOE back to isIos should work, but ultimately @badlogic has to decide.
Just my 2 cent :)

Please ignore this pull request, we are working on a new one with proper Multi-OS Engine 1.3.0 (currently beta) support.
