J2ObjC is an open source tool created by Google to translate Java code into corrresponding Objective-C code that can be run on iOS. The idea is to reuse Java business code between Android, web and iOS. For the web the translation is done with GWT. This tool does not deal with UI code which needs to be written separately for each platform.
Swift has overtaken Objective-C in the TIOBE index, an internet-sourced rating of programming languages based on a variety of different sources.
Apple has open-sourced Swift under a permissive Apache license, following up from a promise made at WWDC 2015 that it would be available before the end of the year. The release includes information about Swift 3.0, a package manager, and a binary package for Linux systems. InfoQ looks into what it means and what effects it will have for future iOS and OSX development.
Facebook has open sourced Infer, a static analysis tool for C, Java and Objective-C.
While there were rumors that Microsoft would be adopting Android for the Windows 10 platform, no one expected the announcement that iOS applications would also be adopted. This is made possible, by combining C2 with Clang.
Carthage is a dependency manager for Objective-C and Swift projects aims to be "ruthlessy simple," says its author Justin Spahr-Summers. Carthage has been developed at GitHub and its philosophy is "delegating tasks to Xcode and Git" as much as possible so developers can use the tools they "are already familiar with."
Orta Therox, a core contributor to the CocoaPods project, last week announced that the project has now topped 1 million downloads. This announcement rounds off a year which has seen significant developments in the project and growth in its user base.
Best.ly offers support for A/B-testing mobile applications without the need for code changes and resubmitting to an app store. Currently, there is only a native library for the iOS platform but libraries for the Android eco-system are already in development and will be available soon. Experiments can be administrated online, adjusted during runtime and monitored in realtime.
Create any “flexible” or “extensible” file format and sooner or later a group of developers will start complaining about validation. For JSON, several options are starting to spring up.
Daniel Jebaraj shares with InfoQ the idea behind the launch of Succinctly series ebook and also shared the future roadmap.
Clutch enables developers to write hybrid applications for iOS and to run A/B test experiments on iOS and Android devices.
Google has open sourced J2ObjC, a transpiler converting Java source code to Objective-C/C++ source code for the iOS platform.
JetBrains has released AppCode 1.0, their first release of an Objective-C IDE. It requires Mac OSX 10.5 or above. It requires the Apple Developer Tools to be installed (in order to access the simulator and developer headers) but provides more advanced refactoring and code smell detection. AppCode has a free 30-day trial, and discounted licenses until December 31st.
A document has appeared on the Clang website describing requirements for Automatic Reference Counting in Objective-C. This provides a service, akin to C++'s auto, which allows objects to automatically take part in the retain/release/autorelease cycle without requiring the user to do anything explicitly about it.
