| | News | | We all agree that installing the first beta of a new macOS on your primary partition is a bad idea, right? But as Daniel Jalkut noticed, the release notes have a little gotcha if you install it on a new APFS volume, rather than on a new partition. I'm happy that Marc Aupont took the time to write up a great guide to getting up and running with the beta safely. lickability.com | |

| | WWDC | | I think itâs safe to say that given the circumstances, this yearâs WWDC was a complete success. I lost count of the number of times I saw people compliment Apple on the session videos, especially the fact that they can be of different lengths when thereâs no fixed schedule. I feel the same way and feel confident in saying that the videos this year got the information across in a much more engaging way than a âtraditionalâ conference talk. I also saw several people say theyâd be happy if future editions were entirely virtual too. I certainly think there are lots of positive lessons thatâll come out of this yearâs event, but I do hope that we havenât seen the last in-person WWDC. I know itâs entirely my fault, but I didnât make as much of this yearâs conference as I usually do. I attended several online events, met some new people, and watched a couple of session videos, but I found it hard to take full advantage of the week. The fact that I was sitting at my desk at home meant that what I mostly did this week was⊠work! đŹ One advantage of being in a physical location for a conference is that it forces you to pay attention and take advantage of whatâs happening. I know this is entirely my fault, but Iâm sure Iâm not alone.
So, letâs get started with this weekâs links! I say this every year, but itâs worth repeating. I wonât try to sum up every announcement or cover every new API this week. Not only would that be impossible, but how would I keep you busy for the rest of the summer if I covered everything today? đ For almost nine years, this newsletter has been a collection of links that caught my eye during the week. Itâs the same this week, and itâll be the same next week. If weâre lucky, we might be getting close to digesting everything by September. đ€ | |

| | Tools | | Apple has tried several times to make custom controls usable in its visual design tools. First, Interface Builder plugins, then @IBDesignable and friends, and now this. I love that the overhead when creating the control is virtually nothing, so it feels like this one might stick! đ Sarun Wongpatcharapakorn has the details. Sidenote: I forget who created it now, but I remember a set of standard UI controls that had a dark appearance, for use in inspector style windows back in the 10.4/10.5 era that had an IB plugin. The controls were great, but the IB plugin was more trouble than it was worth. Can anyone remember who made them? sarunw.com | |
| In my opinion, scroll smoothness is one of the most critical aspects of whether people will perceive your app as performant. So, I was incredibly happy to see Xcode 12 include a way for you to visualise and test how your apps perform when scrolling. â€ïž There's a little more information on how to activate the feature, but I haven't seen this anywhere else apart from in this tweet from Antoine van der Lee. twitter.com | |

| | Code | | The application delegate has been a cornerstone of Cocoa since before the word only meant a chocolatey evening beverage. đ€© With this year's SwiftUI release, the app delegate is no longer necessary in a SwiftUI app. It's not yet a complete replacement, but it's a sign of where things might be heading in future years. John Sundell takes a quick look. wwdcbysundell.com | |
| The most surprising thing about this year's SwiftUI changes is that they were mostly additive! Great news if you adopted early and have existing code, but it also shows what a great job the team did with the API design last year. There were lots of additions though, and Paul Hudson immediately started writing a million new blog posts. đ hackingwithswift.com | |
| Did Apple just deprecate table views?! đ€Ż Ever since collection views appeared, with none of the "standard" cell fields like textLabel and detailTextLabel the design of the table cell API felt a little outdated. It's been possible to use collection views in place of table views for a long time, but this year's changes make that the recommended option. Here's Hesham Abd-Elmegid with a rundown of what's new. I also think that Fernando Bunn might have summed this up in the best way! đ swiftmentor.io | |
| Here's Mohsen Alijanpour talking about a topic that has been on my mind recently too. Where UIKit pushed you towards MVC, SwiftUI is completely unopinionated in terms of your application architecture. Even more so with this year's release, where you may also say au revoir to the AppDelegate. Even though the framework isn't opinionated in software architecture anymore, I would like to see Apple give some guidance on architecture. Leaving it completely open is fantastic for those people who are passionate about software architecture, but might be bad for the platform on a broader scale. mohsen.dev | |

| | Design | | The Human Interface Guidelines are worth reading from cover to cover every time there's a new iOS release, and this year is no different. Even better, this year's new version of the document came with release notes, just in case you had memorised the rest of the document! đ apple.com | |

| | Business and Marketing | | I'd be surprised if last week's shouting prompted this as Apple doesn't tend to make sudden moves in situations like that. Regardless of why this happened, it's a good step forward: Additionally, two changes are coming to the app review process and will be implemented this summer. First, developers will not only be able to appeal decisions about whether an app violates a given guideline of the App Store Review Guidelines, but will also have a mechanism to challenge the guideline itself. Second, for apps that are already on the App Store, bug fixes will no longer be delayed over guideline violations except for those related to legal issues. Developers will instead be able to address the issue in their next submission.

| | Videos | | A grid control was widely anticipated in this year's version of SwiftUI, and sure enough, it made an appearance this week. Here's Ben Scheirman with a video showing how to get started with SwiftUI grids. It's nowhere near as flexible as a UIKit collection view, but that's OK. It can do the vast majority of what people actually use collection views for, in a much more approachable way. nsscreencast.com | |
