Using Claude Code to Build an Apple Watch App
Matt Maher shows how Claude Code became a silent partner in the development of 'Nudger,' automating repetitive tasks, solving debugging headaches, and even suggesting tailored code snippets for complex features. You'll discover how this AI tool complemented Xcode's robust capabilities, from crafting a scalable app foundation to refining user experience details. Whether you're an experienced developer or just curious about the intersection of AI and app creation, this journey reveals how technology can simplify the intricate process of building for watchOS. It's not just about writing code—it's about rethinking how we create. AI-Powered Apple Watch App Building the Foundation with Xcode
The development of any successful watchOS app begins with a robust foundation, and Xcode serves as the cornerstone of this process. Xcode provides the essential tools required to establish the basic structure of an Apple Watch app. For 'Nudger,' this involved creating a framework to support its core features: One-time reminders, referred to as 'nudges.'
Recurring alerts, called 'nags,' which repeat over a specified duration.
Using Xcode, the development team constructed the app's skeleton, including its user interface and notification system. This initial setup ensured compatibility with watchOS and laid the groundwork for further enhancements using Claude Code. By using Xcode's capabilities, developers were able to focus on building a scalable and functional base for the app. Enhancing Functionality with Claude Code
Claude Code, an AI-powered coding assistant, played a pivotal role in implementing the app's functionality. By providing the AI tool with a detailed project requirements document (PRD), developers generated customized code snippets tailored to 'Nudger's' needs. These snippets addressed critical features such as: Setting reminders and managing notification triggers.
Allowing haptic feedback for notifications.
Customizing user preferences for alerts.
The AI tool streamlined the coding process by automating repetitive tasks and offering solutions to common challenges. For instance, when integrating time-based notification triggers, Claude Code suggested efficient methods for scheduling alerts and managing user settings. This allowed developers to allocate more time to refining the app's user experience and making sure its functionality aligned with user expectations.

Debugging is an inevitable part of app development, and 'Nudger' was no exception. Issues such as framework import errors, notification handling bugs, and app crashes arose during the process. The combination of Xcode's debugging tools and Claude Code's error resolution capabilities proved invaluable in addressing these challenges.
For example, when notifications failed to trigger at the correct times, Claude Code identified errors in the scheduling logic and suggested corrections. Similarly, Xcode's debugging interface flagged problems with framework dependencies, which were resolved with Claude Code's assistance. This iterative debugging process ensured that the app functioned as intended in the watchOS simulator, providing a stable and reliable user experience. Testing in the watchOS Simulator
Thorough testing in the watchOS simulator was a critical step before deploying the app to an actual Apple Watch. The simulator provided a controlled environment to evaluate the app's performance, user interface, and notification system. For 'Nudger,' testing scenarios included: Setting one-time reminders and recurring alerts.
Customizing notification preferences, including haptic feedback and sound alerts.
Assessing the app's responsiveness and usability.
The simulator also enabled developers to test haptic feedback, a key feature of the app, under simulated real-world conditions. This phase was essential for identifying and resolving any remaining issues, making sure the app was polished and ready for deployment. Key Features and Practical Benefits of 'Nudger'
'Nudger' offers a range of features designed to enhance productivity and user experience. These include: Customizable reminders, with options for one-time 'nudges' and recurring 'nags.'
Notifications that include haptic feedback and optional sound alerts.
and optional sound alerts. A user-friendly interface for adding, editing, and deleting reminders.
These features make 'Nudger' a practical tool for managing daily tasks and staying organized. By combining simplicity with functionality, the app addresses the needs of users seeking an efficient way to manage their schedules. Lessons Learned and the Role of AI
The development of 'Nudger' was not without its challenges. Framework import errors, notification handling issues, and debugging complexities required careful attention. However, the integration of Claude Code with Xcode proved to be a powerful combination, simplifying the resolution of these problems and accelerating the development timeline.
This project highlights the potential of AI tools like Claude Code in modern app development. By automating repetitive tasks and providing expert-level guidance, these tools empower developers to focus on creating user-centric applications. The success of 'Nudger' underscores how AI can enhance productivity, reduce development time, and simplify complex tasks, paving the way for more efficient and innovative app creation.

New Trump human resources czar distances himself from Elon Musk
WASHINGTON, July 21 (Reuters) - The new chief of the agency spearheading efforts to slash the federal workforce said on Monday he had no personal ties to tech billionaire and former Trump advisor Elon Musk, pledging to faithfully execute President Donald Trump's agenda. "I have zero personal relationship with Elon Musk. I have talked to Elon Musk once on the phone in my life," Scott Kupor, who was sworn in to lead the Office of Personnel Management earlier this month, told reporters. The comments underscored lingering questions about the loyalties of Silicon Valley tech entrepreneurs among Trump administration officials following a public spat between Trump and Musk that led to a deep rift between the two former allies. Kupor said he had told Trump and other people in the White House that "my job is to do the agenda that the president lays out to the best I can." "But I'm not going to do it consistent with someone else's objectives that are inconsistent with what the president wants to do," he added. Musk, who spent over a quarter of a billion dollars to help Trump win November's presidential election, led the Department of Government Efficiency's efforts to slash the budget and cut the federal workforce until his departure in late May to refocus on his tech empire, including electric vehicle maker Tesla (TSLA.O), opens new tab. While Trump hailed Musk's tenure upon his departure, the president quickly pulled the nomination of Musk ally and tech entrepreneur Jared Isaacman to lead NASA. Reuters previously reported that Musk was disappointed by Isaacman's removal. The president also threatened to cancel billions of dollars worth of contracts between the federal government and Musk's companies after Musk denounced Trump's tax-cut and spending bill as a "disgusting abomination." Prior to taking the helm at OPM, Kupor was a partner at Silicon Valley-based venture capital firm Andreessen Horowitz, which invests in Musk's AI startup Xai as well as SpaceX.

Labour's drive to build AI data farms 'will send water bills rocketing' by 30 per cent over next five years, report warns
Prime Minister Keir Starmer 's drive to build huge artificial intelligence data centres will help push up water bills by 30 per cent over the next five years, an independent report warns. The banks of computer equipment needed to advance AI models require huge volumes of water to fuel cooling systems. Ministers will also scrap the regulator Ofwat to make way for a new body to try to tame 'Wild West' water firms after the recommendations. But consumers will also pay the price of tackling future sewage spills and renewing crumbling infrastructure. The report's author – Sir Jon Cunliffe, a former deputy governor of the Bank of England – made 88 recommendations to turn around the ailing industry. His Independent Water Commission review tackles the issues of pollution, soaring bills and staggering pay awards and bonuses for failing company bosses. In the report, he warns that bills will have to rise because of a failure to invest in the sector amid a growing population and climate change. He also says that Labour policies including building 1.5 million more homes and more data centres to power AI will put 'pressure' on the system. The report's author – Sir Jon Cunliffe, (pictured) a former deputy governor of the Bank of England – made 88 recommendations to turn around the ailing industry Sir Jon also recommended the introduction of social tariffs to provide support for customers who are unable to pay their bills. He told BBC Radio 4's Today programme yesterday: 'The inescapable fact is that it costs more to produce drinking water and it will cost more to deal with our waste water as we go forward. 'When you look at the pressures on the water system – look at population growth [and] we want to have data centres in this country – they put huge demands on water. 'We have to accept them. But we have to plan for them, we have to decide where the priorities are, and we have to decide how to manage the trade-offs. At the moment, that is just not happening.' The report also said that data centres used by AI companies have a 'high water need'. It cited research from Oxford University that argued 'regional water stress must be considered for each data centre'. In January, Sir Keir launched an 'AI Opportunities Action Plan', which welcomed billions in investment from overseas tech companies to build data centres in the UK. Environment Secretary Steve Reed said yesterday that the Government would scrap the watchdog Ofwat, adding that the water industry is 'broken' and has been allowed to fail under a 'regulatory system that let them get away with it'. 'Our rivers, lakes and seas are polluted with record levels of sewage,' he said. He promised to create a 'single, powerful' regulator, bringing the four bodies responsible for water under its control. He also pledged to cut sewage pollution levels in 2024 by half by 2030 through a series of measures including public and private investment.

Looming over two cases threatening Musk's car company is a single question: Can he be trusted?
Elon Musk fought court cases on opposite coasts Monday, raising a question about the billionaire that could either speed his plan to put self-driving Teslas on U.S. roads or throw up a major roadblock: Can this wildly successful man who tends to exaggerate really be trusted? In Miami, a Tesla driver who has admitted he was wrong to reach for a dropped cell phone moments before a deadly accident, spoke of the danger of putting too much faith in Musk's technology — in this case his Autopilot program. 'I trusted the technology too much,' said a visibly shaken George McGee, who slammed into a woman out stargazing, sending her 75 feet through the air. 'I believed that if the car saw something in front of it, it would provide a warning and apply the brakes.' In unusual coincidence, regulators arguing an Oakland, California, case tried to pin exaggerated talk about the same Tesla technology at the center of a request to suspend the carmaker from being able to sell vehicles in the state. Musk's tendency to talk big — whether its his cars, his rockets or his government costing-cutting efforts — have landed him in trouble with investors, regulators and courts before, but rarely at such a delicate moment. After his social media spat with President Donald Trump, Musk can no longer count on a light regulatory touch from Washington. Meanwhile, sales of his electric cars have plunged and so a hit to his safety reputation could threaten his next big project: rolling out driverless robotaxis — hundreds of thousands of them — in several U.S. cities by the end of next year. The Miami case holds other dangers, too. Lawyers for the family of the dead woman, Naibel Benavides Leon, recently convinced the judge overseeing the jury trial to allow them to argue for punitive damages. A car crash lawyer not involved in the case, but closely following it, said that could cost Tesla tens of millions of dollars, or possibly more. 'I've seen punitive damages go to the hundreds of millions, so that is the floor,' said Miguel Custodio of Los Angeles-based Custodio & Dubey. 'It is also a signal to other plaintiffs that they can also ask for punitive damages, and then the payments could start compounding.' Tesla did not reply for a request for comment. That Tesla has allowed the Miami case to proceed to trial is surprising. It has settled at least four deadly accidents involving Autopilot, including payments just last week to a Florida family of a Tesla driver. That said, Tesla was victorious in two other jury cases, both in California, that also sought to lay blame on its technology for crashes. Lawyers for the plaintiffs in the Miami case argue that Tesla's driver-assistance feature, called Autopilot, should have warned the driver and braked when his Model S sedan blew through flashing lights, a stop sign and a T-intersection at 62 miles-an-hour in an April 2019 crash. Tesla said that drivers are warned not to rely on Autopilot, or its more advanced Full Self-Driving system. It say the fault entirely lies with the "distracted driver" just like so many other 'accidents since cellphones were invented.' Driver McGee settled a separate suit brought by the family of Benavides and her severely injured boyfriend, Dillon Angulo. Shown dashcam video Monday of his car jumping the road a split second before killing Benavides, McGee was clearly shaken. Asked if he had seen those images before, McGee pinched his lips, shook his head, then squeaked out a response, 'No.' Tesla's attorney sought to show that McGee was fully to blame, asking if he had ever contacted Tesla for additional instructions about how Autopilot or any other safety features worked. McGee said he had not, though he was heavy user of the features. He said he had driven the same road home from work 30 or 40 times. Under questioning he also acknowledged he alone was responsible for watching the road and hitting the brakes. But lawyers for the Benavides family had another chance to parry that line of argument and asked McGee if he would have taken his eyes off the road and reached for his phone had he been driving any car other than a Tesla on Autopilot. McGee responded, 'I don't believe so.' The case is expected to continue for two more weeks. In the California case, the state's Department of Motor Vehicles is arguing before an administrative judge that Tesla has misled drivers by exaggerating the capabilities of its Autopilot and Full Self-Driving features. A court filing claims even those feature names are misleading because they offer just partial self-driving Musk has been warned by federal regulators to stop making public comments suggesting Full Self-Driving allows his cars to drive themselves because it could lead to overreliance on the system, resulting in possible crashes and deaths. He also has run into trouble with regulators for Autopilot. In 2023, the company had to recall 2.3 million vehicles for problems with the technology and is now under investigation for saying it fixed the issue though it's unclear it has, according to regulatory documents. The California case is expected to last another four days. —-
