Earlier today, I stepped into my very own spatial computing experience as I used my brand-new Vision Pro for the first time. \ud83e\udd7d<\/p>\n
It\u2019s easy to think that the Vision Pro is old hat now. It launched in the US five months<\/em> ago, and that\u2019s an eternity in tech. \ud83d\udc68\u200d\ud83e\uddb3 The tech news cycle has long since moved on to other topics, but it\u2019s still such early days for the platform. Here in the UK and for everyone in a few other select countries, it\u2019s day one, and millions of others have no release date.<\/p>\n In some ways, I\u2019m glad the hype and tech press around the platform has died down. This is a long-term bet from Apple, and the best-case scenario will be similar to the Apple Watch, in that it\u2019ll take time to succeed and mature. That maturing will come primarily from Apple, continuing to plough huge<\/em> amounts of money into visionOS and future hardware projects that hopefully bring the devices in range of more people\u2019s budgets. Just as important, though, will be persuading third-party developers to invest their time and effort.<\/p>\n What\u2019s clear from the couple of hours I have spent using the device so far is how well the basics work. I was comfortable navigating the windowing system within a few minutes, and it feels stable and predictable. It\u2019s early days and I\u2019m still very much in the honeymoon period with it, and I know it\u2019s not perfect, but the basics feel solid.<\/p>\n So the million (or billion) dollar question is, will third-party developers choose to invest that time and effort? I\u2019ve been keeping a close eye on the community since the US launch, and have noticed that the number of people writing about development in visionOS increased<\/em> as the hype faded. You\u2019ve got people with dedicated blogs, like Donovan\u2019s Vision Blog<\/a>, and StuVision<\/a>, sites like Create with Swift<\/a> and elkraneo<\/a> who have dedicated landing pages for visionOS posts, and of course, there are plenty of occasional posts on other blogs, too.<\/p>\n Don\u2019t get me wrong, the risks of this platform failing are still significant, but seeing developer interest from third parties will reduce those risks and I can\u2019t wait to see where it goes from here!<\/p>\n Oh, and if you have an app on the store or a TestFlight in progress for a visionOS-native app. reply to this email with a link. I\u2019d love to check your app out!<\/p>\n Dave Verwer<\/p>\n Join the FREE iOS Architect Crash Course<\/a><\/p>\n If you\u2019re a mid\/senior iOS developer looking to improve both your skills and salary level, join this free online crash course. It\u2019s available only for a limited time, so get it now<\/a>.<\/p>\n Hello Developer: New visionOS sample code<\/a><\/p>\n Talking of visionOS, the latest issue of Apple\u2019s Hello Developer<\/a> newsletter (which is well worth subscribing to) announces multiple new sample code projects highlighting visionOS! \ud83d\udc4d Scroll down to the \u201cNew sample code\u201d section and you\u2019ll find links to three new non-trivial projects. There\u2019s a multi-platform app<\/a>, a RealityKit<\/a>, and one demonstrating Reality Composer Pro<\/a>.<\/p>\n swift-testing-revolutionary<\/a><\/p>\n This package came up during the latest episode of Swift Package Indexing, and I felt compelled to mention it here, too. Kohki Miki<\/a>\u2019s latest work will take your XCTest tests and do its best to convert them to run with Apple\u2019s new swift-testing<\/a> package. From our testing on the SPI source code, it works remarkably well!<\/p>\n Kaleidoscope 5<\/a><\/p>\n Each time there\u2019s a new major release of Kaleidoscope I wonder what new features the developers can add to a For full disclosure, the developers provided me a review copy of the app.<\/p>\n Tips & tricks with the iOS 18 ScrollView API<\/a><\/p>\n I believe that part of the struggle SwiftUI has had, and why we saw so many \u201cIs SwiftUI ready for production\u201d blog posts a couple of years ago is that the set of \u201ceasy\u201d tasks and \u201cdifficult\u201d tasks are so different between SwiftUI and UIKit. For example, as Thomas Ricouard<\/a> says:<\/p>\n It\u2019s a simple Luckily, the set of \u201ceasy\u201d tasks that SwiftUI has always excelled at remains as it also knocks down the list of previously difficult ones. \ud83d\udc4d<\/p>\n Understanding Swift 6 concurrency via evolution proposal analysis<\/a><\/p>\n I linked to Matt Massicotte<\/a>\u2019s series of posts on Swift concurrency and data race safety just before WWDC as I thought he was finished<\/a>! He wasn\u2019t done then, but he is now<\/a>! So, while I wouldn\u2019t usually link to the same articles again so quickly, his journey through Swift Evolution adding examples and context as he goes has been so great that it\u2019s worth checking out the entire<\/em> set if you want to understand Swift 6.0 better.<\/p>\n Blend Modes in SwiftUI<\/a><\/p>\n Have you ever caught yourself saying \u201cOh, blend modes! Those are what Photoshop has, right?\u201d as someone mentions them? If so, get some clarity on what each of them does with this beautifully illustrated guide by Aryaman Sharda<\/a>, and try not to think about why this page<\/a> doesn\u2019t have a similar set of images. \ud83d\ude2c<\/p>\n Using PreviewModifier to build a previewing environment<\/a><\/p>\n I must admit I still don\u2019t use SwiftUI previews \ud83d\ude2c I prefer the \u201cold fashioned\u201d way of building and running when I need to see a view in use. I should probably re-think that, though, as previews have improved and improved over the years since they were first introduced. Here\u2019s Donny Wals<\/a> with a recap of the latest improvements available in the latest SDK.<\/p>\n An Infinite Canvas<\/a><\/p>\n This was the perfect video for me last night on the eve of my Vision Pro arrival.

diff<\/code> app. Throughout the v4.x releases, they introduced several features to enable closer integration with git, and v5 takes that one step further by allowing you to open source repositories with some super handy views for branch comparison and easy ways to see what changes were made in the last timer period or number of commits. It\u2019s not a cheap app, but it is absolutely the best at its job.<\/p>\nCode<\/h2>\n

ScrollView<\/code> + LazyVStack<\/code> Implementation with infinite scrolling (pagination) and a way to hide the navigation bar and the tab bar when scrolling. This is quite a standard behavior when using UIKit, but until iOS 18, it was hard to reproduce using SwiftUI.<\/p>\n<\/blockquote>\nVideos<\/h2>\n
