check PR301 for fix.
Kees van Dieren asked for solution about the issue he has with submitting app to apple store. Issue he had is following:

ITMS-90725: SDK Version Issue - In July 2018, iOS app updates submitted to the App Store will need to be built with the iOS ‘11.0’ SDK or later, included in Xcode [9.0] or later. Make sure to update Xcode for future app deliveries. After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.

After checking list of possible source of problems following poped up:

$ otool -l IosEsLauncher | grep -A 4 LC_VERSION_MIN_IPHONEOS
cmd LC_VERSION_MIN_IPHONEOS
cmdsize 16
version 8.0
sdk n/a
Load command 10

sdk n/a – come-on I had it with home made SDK on windows/linux and it should not happen on Mac but it there as well.

Root case

Application with RoboVM target crashes with EXC_BAD_ACCESS, investigation shows that this happens on null pointer exception (NPE) that enclosed in corresponding try-catch block and shall not break away? Already covered in Tutorial: Crash Reporters and java exceptions.
Root case is same – signals.
Solution is same – use Signals.installSignals.
Post bellow describes how to deal with it and introduces changes into framework template.

iOS 11.4 were generated using bro-gen. Check pr299 for details.
This update delivers following frameworks:

• ClassKit
• Metal Performance Shaders (available since iOS 9 but missing in RoboVM)

Previous debugger maintenance allowed to build kotlin code for debug and attach debugger for it. It was even possible to step-in into kotlin code. Absence of any kotlin experience didn’t allow to test it deeper. As it kept failing on simplest case, setting of breakpoint, with following message:

No executable code found at line XX in class YYYY

Root case of this – debug plugin and debugger considered JVM code as compiled from Java file and returned .java file extension everywhere.
The fix is bellow:

Debugger maintenance.
History Robovm compiler crashes with Kotlin modules when compiling for debug #295
Fix PR296

Fixed:

1. Crash when trying to debug application that contained Kotlin data modules (or any synthetics methods);
2. Crash when starting debugger for binary that contains classes with error (e.g. class not found for dependencies)

Details:

Today bug-fix/maintenance delivers following problem, following such obj-c code:

typedef enum LogLevelValues
{
    IS_LOG_NONE = -1,
    IS_LOG_INTERNAL = 0,
    IS_LOG_INFO = 1,
    IS_LOG_WARNING = 2,
    IS_LOG_ERROR = 3,
    IS_LOG_CRITICAL = 4,

} LogLevel;

- (void)sendLog:(NSString * )log level:(LogLevel)level tag:(LogTag)tag;

is being converted into following broken Java one:

Event after fixing signature case apple keeps rejecting applications with Stickers app extension with message:

Invalid iMessage App - Your iMessage app contains an invalid sticker pack. The app may have been built or signed with non-compliant or prerelease tools. For more information, go to developer.apple.com.

user @sofroma investigated case and has found that Xcode additionally copies support files into Apple store package. The package was missing following files:

• MessagesApplicationExtensionSupport/MessagesApplicationExtensionStub
• MessagesApplicationSupport/MessagesApplicationStub

These files are part of iPhoneOS platform and available as part of Xcode at following location: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Application Support

The fix is to copy these file during packing ipa, check this commit for details.
Sadly these files are part of XCode and can’t be used on Windows/Linux in corresponding RoboVM port

Today bug-fix/maintenance delivers following:

1. Fixed automatic profile/signature selection as it was picking first random signature with iPhone Developer|iOS Development prefix;
2. Improved app-extension support: apple was rejecting binaries due missing provisioning profile and entitlements.
3. Small improvements to bro-gen that can now pick string macro into constants

RoboVM gradle plugin maintenance PR292, in it:

1. added dependency to build task to force java compilation for every RoboVM tasks. Otherwise commands like launchIOSDevice will fail as java classes are not generated.
2. added description to tasks:

   > gradle tasks
   MobiVM tasks
   ------------
   createIPA - Creates .ipa file. This is an alias for the robovmArchive task
   launchConsole - Runs a console app
   launchIOSDevice - Runs your iOS app on a connected iOS device.
   launchIPadSimulator - Runs your iOS app in the iPad simulator
   launchIPhoneSimulator - Runs your iOS app in the iPhone simulator
   robovmArchive - Compiles a binary, archives it in a format suitable for distribution and saves it to build/robovm/
   robovmInstall - Compiles a binary and installs it to build/robovm/
   

3. added logic not extracting same file on every launch and do clear cache when new files extracted just to avoid bug cases when incompatible data stays in cache, check post by @dthommes. Similar as it was done for Idea plugin.
4. added support for launching debugger, similar as @dukescript did for ‘maven plugin’:

   .. start with
   > gradle --no-daemon -i -Probovm.debug=true -Probovm.debugPort=7778 -Probovm.arch=x86_64 "-Probovm.device.name=iPhone SE" launchIPhoneSimulator
   .. attach with
   > jdb -attach 7778
   

UPDATE: possible solution delivered
Previous post on this topic described how to hack android.jar.
That approach has own flaws such as it is not working properly with recent Android Studio. Now there is another way to fight the issue – remove android-gradle and java-gradle in automatic way.
