bro-gen: whats new after ios12 binding


bro-gen received several updates and new features during handling iOS12 bindings, mostly fixes but there are new ones. All changes are pushed to github.
Whats new:

RoboVM and Vector data type. Why ARKit is not working


User pjwj reported problem when he was trying to use ARKit (first one?):

Values in this matrix are not as I expect them to be, as translation components are very small (for example x*10^-35). Therefore virtual objects I’m adding to the AR scene are always positioned close to the origin.

Quick investigation shown that RoboVM is not able to handle vector data types such as simd_float4x4 (mapped to MatrixFloat4x4 in RoboVM) at compiler level. As result all vector data is passed incorrectly.
Investigation and fix is bellow.

Tutorial: [LGSideMenuController] using bro-gen to quick generate bindings


This tutorial mostly copies old one, please refer to it for more details.
It cover quick binding of LGSideMenuController.

binding: few lessons learned


While testing binding of Network.framework there were several discoveries:

  1. out of box binding to global values or bridge functions from linked static library will not work;
  2. RoboVM is not able to compile global value that returns a obj-c block;
  3. Don’t use method name copy when binding function. It will crash during compilation.

Details and workarounds bellow.

iOS 12.0 and 12.1 bindings


iOS 12.0 + 12.1 bindings have arrived as PR. These was massive API update as part of iOS12 release which includes new frameworks:

  • AuthenticationServices
  • CarPlay
  • CoreServices
  • IdentityLookupUI
  • NaturalLanguage
  • Network

Also this release delivers lot of API changes to existing framework which, bright highlights are:

  • ARKit 2
  • Metal Performance Shaders;
  • and others

Beside updating API itself cocoatouch receives lot of patches as result of improvement of bro-gen script. (TODO: There will be detailed post about this)
Following was improved:

  • fixed lot of broken enum entires (names were generated cut or prefix was not determinated);
  • exposed missing inherited constructors which added lot of missing constructors;
  • applied inherited configuration that reduce number of config entries to be put in yaml;
  • methods where WithXX was generated were mostly located and correctly renamed (this probably might be a breaking change);
  • lot of different minor fixes to generator;

It is to be tested for other breaking changes but I hope it will be merged back in week or two.

RoboVM: Workaround for enhance.co


As continue of previous post here is a workaround:
Solution is to keep static linking to Enhance class from libconnector.a. To achieve result lets introduce objc class that extends(and as result statically links) from Enhance:

Why enhance.co injected functionlity does not work mostly in RoboVM (as per today)


User OceanBreezeGames reported following issue on Gitter channel that was interesting to investigate:

Enhanced ipa fails with:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[Enhance isInterstitialReady]: unrecognized selector sent to class 0x103343eb8'

Tried enhancing the app several time and it sometimes worked and sometimes not. For start how it expected to work:

RoboVM maintenance: keeping up to date


Today maintenance PR326 delivers following:

  • fixes gradle’s ` Warning: org.robovm.apple.uikit.UIWindow is a phantom class! [issue](https://gitter.im/MobiVM/robovm?at=5b98e2c4f3c26b08f6664e07) when using v4 and implementation` as dependency command. This was happening due using outdated configuration name in dependency path resolution:
// configure the runtime classpath
Set<File> classpathEntries = project.getConfigurations().getByName("runtime").getFiles();


 // The name of the "runtime" configuration. This configuration is deprecated and doesn't represent a correct view of
 // the runtime dependencies of a component.
  • update to Idea 2018.2.3: fixes broken Idea plugin build due to gradle dependencies needs to be specified
  • update to Xcode10: sdk 10.14 and removed x86 mac target as deprecated and breaks build process

okhttp3 v3.11.0: playing nice with RoboVM


As stated in #325 it doesn’t work. The reason for this is that okhttp3 detects RoboVM as Android (as there are corresponding providers classes present). And crashes while tries to access Android’s Build class, which is not found:

java.lang.NoClassDefFoundError: android/os/Build$VERSION
	at okhttp3.internal.platform.AndroidPlatform.getSSLContext(AndroidPlatform.java:434)
	at okhttp3.OkHttpClient.newSslSocketFactory(OkHttpClient.java:282)

Dirty and fast solution is just to add Build class to your class path:

package android.os;

public final class Build {
    public final static class VERSION {
        public final static int SDK_INT = 16; // android 4.1

Long term solution would be updating to OpenJDK10.
