fix
Background:
There is many API in CocoaTouch where argument is ObjC protocol type. In RoboVM protocols are mapped into interfaces. The problems begin when bro-bridge tries to marshall this protocol implementation into the native object:
UIToolbar toolbar = new UIToolbar();
toolbar.setDelegate(bar -> UIBarPosition.Any);
causes:
java.lang.ClassCastException: com.mycompany.myapp.Main$$Lambda$1 cannot be cast to org.robovm.objc.ObjCObject
at org.robovm.objc.ObjCObject$Marshaler.protocolToNative(ObjCObject.java:388)
at org.robovm.apple.uikit.UIToolbar.$m$setDelegate$(Native Method)
at org.robovm.apple.uikit.UIToolbar.setDelegate(UIToolbar.java)
at com.mycompany.myapp.Main.didFinishLaunching(Main.java:26)
Root case: protocol marshaller can handle only ObjCObject. Indeed, there is no way to marshal random Java class to ObjC native world.
The existing workaround:

AltPods were updated to v1.15.0-SNAPSHOT to sync with recent releases.
Updated pods
These pods were pushed to https://oss.sonatype.org/content/repositories/snapshots maven repo under 1.15.0-SNAPSHOTS version.
Source code @github
Updates are not fully tested, please open issue if bug found.
NB: AltPods – are robopods kept at my personal standalone repo. This is done to prevent main robopods repo from turning into code graveyard. As these pods have low interest of community and low chances to be updated.

fix
swift
Background:
First time issue was reported on gitter
libswiftCoreMIDI.dylib is not found in swift paths
Later it was communicated that workaround doesn’t work during submition to Apple:
ERROR ITMS-90209: “Invalid Segment Alignment. The app binary at ‘SwiftSupport/iphoneos/libswiftCoreMIDI.dylib’ does not have proper segment alignment. Try rebuilding the app with the latest Xcode version.”
Issues:
- RoboVM can detect swift dependencies only in dynamic frameworks. For static libraries/frameworks workaround was introduced.
- Today dynamic framworks might link again runtime swift libraries – these should not be copied to
.app/Frameworks folder. These dependecies can be observed using otool -L command:
/usr/lib/swift/libswiftWebKit.dylib (compatibility version 1.0.0, current version 610.1.28, weak)
@rpath/libswiftAVFoundation.dylib (compatibility version 1.0.0, current version 1991.1.1, weak)
there libswiftWebKit.dylib is from runtime location(and RoboVM can’t copy it) and libswiftAVFoundation.dylib to be bundled into application (have to be bundled).

@vaaneeunbnd reported an issue at gitter:
I am using GLKMatrix4 as a modelviewmatrix in my robovm app but whenever I try to apply translation to it:
modelViewMatrix.createTranslation(0.0f, 0.0f, -1.0f);
It crashes without a debug log, can someone please help me with this
But diagnostic report contains a crash log:

bro-gen
It is a follow up of previous post: bro-gen: static methods and polymorphism.
CocoaTouch was regenerated with updated bro-gen and it caused 1000+ changes in source code. There are massive supportsSecureCoding(), getLayerClass() and also it exposed not available before constructors and APIs.
The changes proposed as PR543 and targeted to 2.3.13 version of RoboVM.

bro-gen
There is one binding trick related to inherited class methods/properties in objc code. Polymorphism is not available for static methods in Java and compiler resolves target for static call during compilation time. Following obj-c code and Java binding demostrate the issue:
@interface Abstract : NSObject
+(void) test;
@end
@interface TestObject : Abstract
@end
Corresponding binding:
public class Abstract extends NSObject {
public Abstract() {}
@Method(selector = "test")
public static native void test();
}
public class TestObject extends Abstract {
public TestObject() {}
}
Java call TestObject.test() will fail while obj-c call [TestObject test] is not. Root case – static method invocation is resolved compilation time and test() method is present in Abstract. This produces Abstract.test() call that corresponds to obj-c call [Abstract test].
The fix
Is to copy all static methods/properties from super-classes/protocols into target class. Bro-gen script was updated to do this automatically.

tutorial
Dealing with Android Studio always tricky, v4.1 brings another set of issues to solve.
Installing the plugin
2.3.10 is available in JetBrains marketplace and can be installed directly from plugin settings dialog. But due wrong configuration it is not visible in Android studio. There are few options for Android studio:
Install manually
Download .zip file from MobiVM site and use Install Pluging From Disk... option.
Important: Safari will automatically unpack .zip file, it should be downloaded without unpacking and installed as .zip!
Install from custom plugin repository
These custom repositories point to files located at MobiVM site.
In settings dialog:
- select
Manage Plugin Repositories;
- add
https://dkimitsa.github.io/assets/mobivm-release.xml for installing the latest release;
- or add
https://dkimitsa.github.io/assets/mobivm-snapshot.xml for installing the latest snapshot;
Then switch to Market place search for MobiVM;
