Stacktrace Podcast 042: “Hiding in plain sight”

Stacktrace Podcast

Continuing to analyze the announcements made during this year’s WWDC, on this episode, John and Rambo turn their attention to the Swift Package Manager — and how the fact that it’s now integrated into Xcode is a big deal for many Swift developers. Also, how did Apple manage to hide SwiftUI for all those years, and do we think that other parts of Apple’s SDKs may be getting the “Swift UI treatment”?

Stacktrace Podcast 041: “Craig ruined my translucent dreams”

Stacktrace Podcast

John and Rambo dive deeper into backend-driven UIs using SwiftUI, as well as transparent backgrounds for third party apps, and the potential of using NFC for automation purposes. That, and more reflections on this year’s WWDC announcements, and whether the Mac Pro is actually designed for developers.

Stacktrace Podcast 040: “From Swift to spelunking”

Stacktrace Podcast

It’s time to dive much deeper into SwiftUI! John and Rambo talk about everything from how and when to adopt SwiftUI, to how it relates to app architecture, and how the Swift language itself has evolved to support its declarative new syntax. But of course there’s also a brand new Rambo Report, and the WWDC poker results are finally revealed.

iOS 13 includes references to Apple’s Tag device for tracking personal items

iOS 13 Apple tag device

As 9to5Mac has previously reported, Apple is developing a Tile-like device that can be used to track a user’s personal items using the new “Find My” app introduced at WWDC yesterday. The product is known only as “B389” by the people involved in its development.

Now, the first beta of iOS 13 includes an asset package for a device with the product type “Tag1,1”. This type of asset package is used for pairing devices by proximity, the same way as AirPods and HomePod can be paired to a user’s device. The reference was first spotted by Steve Moser and confirmed by 9to5Mac.
