Apple Silicon proposed in PR586. It includes:

• m1 arm64 version of llvm, ilibmobiledevice, hfsconmpressor libraries to allow it being used with arm64 version of java;
• support for arm64 iOS simulator and arm64 MacOSX console target.

How fast it is (compiling classes using 8 threads):

(Mac Mini m1): Compiled 3317 classes in 36.45 seconds
(Mac Pro W3565): Compiled 3317 classes in 111.60 seconds
(MacBook Pro, i5-4278U @ 4 threads): Compiled 3317 classes in 219.09 seconds

How to use

Available at Idea Marketplace (for AndroidStudio as well), also IDE plugins are available for download.

Happy coding!
Please report any issue to tracker.

Android has kotlinx-coroutines-android Dispatcher.Main that coroutine execution on main/ui thread.
It allows writing an effective suspend logic on main thread as described on the usage page:

fun setup(hello: Text, fab: Circle) {
    GlobalScope.launch(Dispatchers.Main) { // launch coroutine in the main thread
        for (i in 10 downTo 1) { // countdown from 10 to 1 
            hello.text = "Countdown $i ..." // update text
            delay(500) // wait half a second
        }
        hello.text = "Done!"
    }
}

Overview

To make Dispatchers.Main available to kotlinx following steps to be done:

AltPods were updated to v1.16.0-SNAPSHOT to sync with recent releases.

New pods

• Kochava v4.5.0

Updated pods

• AppLovinSDK v10.2.0
• AppCenter v4.1.1
• BranchMetrics v1.39.2
• Facebook v9.2.0
• Firebase v7.11.0
• Flurry v11.2.1
• Fyber v7.8.3
• InMobi v9.1.7
• OneSignal v3.4.1
• Pollfish v6.0.0

These pods were pushed to https://oss.sonatype.org/content/repositories/snapshots maven repo under 1.16.0-SNAPSHOTS version. Source code @github

Updates are not fully tested, please open issue if bug found.

Alt-pods binding process includes time-consuming preparation activities like download binaries/copy/update versions etc. An attempt to automate these was made and messy scripts/dumpdeps.kts was born.
It automates following flow:

• gives instruction where to download framework to;
• deletes header files in bro/ folder and copies new;
• deletes java/ folder with existing bindings;
• invokes bro-gen script to perform binding;
• tries to fetch version information from where possible;
• updates version information in pom.xml/readme files;
• can process multiple frameworks in multi-thread mode;

Also its kotlin-script, and it can be debugged in Idea.

Usage

Simple update that makes it working in Idea 2020.1 EAP. Deprecated API where removed and plugin has to be updated.
Also JetBrains has fixed the issue that was making development using Maven model complicated (hooray!).
(Maven model is nice as allows to have code hot-swap)

Changes proposed as PR670

Background

issue #567.
not exact issue but same problem.
In general native-to-Java enum mapping is fragile in RoboVM as most likely app will crash if set of enum items in app differs from one available in system:

Background

issue #561 ExtAudioFile.read() isn’t playing nice anymore. @yajirobe69 in comment described that possible root case it is a due field annotation was changed from @Array({1}) to @ByVal.
buffers field is a flexible array member of AudioBuffer struts. To work with this array required to get pointer to first struct (member itself) and then navigate in it by using methods of Struct class.

Root case

Root case of issue was introduced in e0b6db6. Accessing struct member is a struct kind and is annotated as @ByVal will cause following:

• first element being accessed;
• copied;
• copy of it is returned

While it is normal to read struct by value, in flexible array member case it is wrong as:

• pointer to first struct is required, not pointer to the COPY;
• future operations with copy, e.g. setting elements (at index 1+) might cause memory corruption.

The fix

Background:

issue #557 http request memory corruption crash during SSL handshake http request memory corruption crash during SSL handshake.
Simple test case indeed caused the crash, code to reproduce is following:

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:
