Alf Watt is an experienced software developer with expertise in macOS, iOS and wireless technology. He operates iStumbler Labs, most notably the Wi-Fi monitoring app iStumbler. He’s also a former Apple employee. As a youth, Alf’s first computer was a Commodore 64, and he leaned how to enter the code for computer games. Later, with a Mac plus, Alf learned HyperCard. Alf’s first serious language, however, was Perl. At Apple, Alf became deeply in involved with Wi-Fi and Apple’s AirPort technology, and that provided a foundation for his legendary iStumbler app. That app is now in Mac App Store. We finished with Alf’s description of his new tool called KitBridge which allows iOS developers to bring apps to macOS. Alf is an engaging personality in the Apple world, and you’ll enjoy his stories.
