Prompt to code in Xcode with Claude 3.

There have been rumors that Apple may launch a Copilot for Xcode, though no official plans have been shared publicly yet. In the meantime…

US sues Apple for illegal monopoly over smartphones
The US Department of Justice accused Apple of operating an illegal monopoly in the smartphone market in an expansive new antitrust lawsuit that seeks to upend many of the ways Apple locks down its phone.

The DOJ, along with 16 state and district attorneys general, accuses Apple of driving up prices for consumers and developers at the expense of making users more reliant on its phones. The parties allege that Apple “selectively” imposes contractual restrictions on developers and withholds critical ways of accessing the phone as a way to prevent competition from arising, according to a release.

“Apple exercises its monopoly power to extract more money from consumers, developers, content creators, artists, publishers, small businesses, and merchants, among others,” the DOJ wrote.

The government points to several different ways that Apple has allegedly illegally maintained its monopoly:

• Disrupting “super apps” that encompass many different programs and could degrade “iOS stickiness” by making it easier for iPhone users to switch to competing devices
• Blocking cloud-streaming apps for things like video games that would lower the need for more expensive hardware
• Suppressing the quality of messaging between the iPhone and competing platforms like Android
• Limiting the functionality of third-party smartwatches with its iPhones and making it harder for Apple Watch users to switch from the iPhone due to compatibility issues
• Blocking third-party developers from creating competing digital wallets with tap-to-pay functionality for the iPhone

Google has released Gemma 2B and 7B, a pair of open-source AI models that will allow developers to more freely utilize the research done in the flagship Gemini. Despite their small size, Google claims the Gemma models "outperform significantly larger models in key benchmarks" and are "capable of running directly on a developer's laptop or desktop." They will be available through Kaggle, Hugging Face, Nvidia's NeMo, and Google's Vertex AI.
