Trying to port my LibGDX game to iOS using RoboVM.
When running the app for the emulator I get this error:
Exception in thread "main" java.lang.UnsatisfiedLinkError:

Ok, sounds like you might have done an upgrade to libGDX 1.6.1+
Look in your main build.gradle file for lines that read as follows:
natives "com.badlogicgames.gdx:gdx-backend-robovm:$gdxVersion"
natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-ios"
natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-ios"
If you have such lines change them to read (changes natives to compile):
compile "com.badlogicgames.gdx:gdx-backend-robovm:$gdxVersion"
compile "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-ios"
compile "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-ios"
And see if that fixes the issue.
I just went through several hours not realizing that I had missed a step during update to a newer libGDX and that roboVM is no longer including the bins as part of the ipa build as they are now packaged as JAR's that get sucked in via compile. (no more lib entries in the robovm.xml for these either)

if you have this problem, here's how I solved it: I took an advice from someone on an older forum: -save your classes from the main project -delete the entire project -rebuild from scratch using LibGDX UI Setup -copy back your classes in the main project.
As that guy said, there's always gonna be some very small glitch somewhere that you're missing.
I wasted 3-4 hours with this, then I took tha advice and everything worked like charm :)
