I've never received a calendar and stickers for being a Walt Disney World annual passholder.

I love it!
A calendar opened to June. The character Stitch is exploding through the word June. A sheet of Walt Disney World stickers is placed on top of the days.

I took these screenshots 30 seconds apart from each other. 🤔

(These are my only AirPods.)
The top screenshot is a pop-up that says Chris's AirPods Pro needs charging because the battery is low. The bottom screenshot is asking Siri what the AirPods battery is and the answer is "your AirPods are at 100%".

How do I convince voice dictation that there is not a scenario where I would ever use “U2” in conversation?
U2 truly think of everything.

I was confused why my tip jar choices were always appearing in English in my testing.

This explains it.

The language settings on the device aren't the deciding factor.
/// The name of the product. /// - Note: The title's language is determined by the storefront that the user's device is connected to, /// not the preferred language set on the device. var localizedTitle: String { get }

I've had some good support from the UK for Please Don't Rain even before my talk at Swift Leeds.

Shame on me for not supporting English (UK). Working on fixing that.

This is another example of why I sometimes still use print.

Here it will happily show all of the contents of DayWeather from Apple WeatherKit.

Logger not only won't compile with the same data, but Xcode gives the "unable to type-check" error that doesn't tell you what line the problem is on.
let foundForecasts : Forecast<DayWeather> = foundAllForecasts.1 if let myFirst = foundForecasts.first { print(myFirst) //logitGetUser.debug(myFirst) }

REALLY appreciate this nice write up in @iosdevweekly.com about my blog post for my talk at @swiftleeds.co.uk .

Thank you so much @daveverwer.com !

Business and Marketing I Gave My First Conference Talk! I had to double take when I saw that Chris Wu’s first-ever conference talk was about time zones! That’s quite the topic to start with, Chris, but I’m so glad that you did, and that it inspired this fantastic write-up of your experience. ❤️ I hope it encourages some of you to submit a proposal to your favourite conference for a talk! Videos Swift Leeds Videos 2025 Speaking of Swift Leeds, the organisers finished posting all the session videos from last month’s conference. There are plenty of talks and a panel discussion to pick from. However, given the previous link, it’s worth noting that Swift Leeds had four brand-new speakers: Kim Gyuri, Erin Sparling, Oksana Shcherban, and, of course, Chris Wu, who you read about above.

In my talk at Swift Leeds I mentioned that I sometimes still use print instead of Logger because some things can get truncated.

Apple just wrote back to me about this scenario I opened, where it happens to Double latitude/longitude values.

1/2
Xcode screenshot. The same latitude and longitude values are being displayed in various methods. The first one uses logger and the values are truncated. The second one also uses logger, but wraps the values in string first and they are not truncated. The final version uses print and the values are not truncated.

CURATED FROM THE COMMUNITY I Gave My First Conference Talk Ever considered giving a talk but never dared to do so? Chris Wu did it, and the result is fantastic. Get inspired, take that step!

I'm not seeing a category for weather apps in the new web version of the App Store. ☹️

I keep thinking of things to add to my latest blog post.

For example, the subtle hints I was dropping before I announced I was going to be speaking at Swift Leeds.
A text message that reads "Nobody is picking up on the fact that I seem to be retweeting a lot of Swift Leeds content"

I did get curious what it was like to sit in the back row of @swiftleeds.co.uk .

Still good seats!

Wow this is weird.

On my iPad if I try to share a @bsky.app post via iMessage I get this bizarre keyboard without a spacebar.

I made it a point to state that my sister drew my artwork for my slides with Procreate. 😎

I was foolish enough to interrupt (and quit) feedback assistant when it was taking forever to upload a 2 1/2 MB file.

Now it won't let me log back in. 🫠
Unable to sign into feedback assistant. Thank you for your patience. Please try again later.

Really weird VoiceOver issue I've hit.

These are each just a Text with an accessibilityLabel for an inline lock screen widget.

ViewThatFits has room for the first one and shows it but VoiceOver reads the label from the SECOND one.

If I comment out the second one it reads the correct text. 😵‍💫
ViewThatFits { InlineTempToday() InlineTemp() }

I always let existing Please Don't Rain subscribers keep their existing price even if I've done an increase since.

That makes it easy to spot people that have been supporting the app from the beginning.

This person has and I'm assuming they'll be happy when I release support for Italian very soon.

Wow, Apple just responded to some Xcode feedback of mine that was over 3 years old. I had forgotten I even did this.

Nice to see that issues will still get looked at after that amount of time.

I successfully responded to my App Store rejection by changing my paywall text to the bottom version.

The fact that this paywall has been out for over a month and has previously passed review four times is definitely annoying.
Top version says "Try free for 1 week, then just $8.99/year. Cancel anytime." with a button that says "Start Free Trial". Bottom version says "Just $8.99/year after free trial for 1 week. Cancel anytime." with a button that says "Continue".

I missed the UK so much that I decided to go back.

TIL that you can easily copy some HTML from a Bluesky post to use it to embed it in your blog.
A new blog entry I'm starting to write that contains a sample Bluesky post for a test where I talk about speaker training at Swift Leeds.

I'm late to the party but I just used Note's transcription feature for the first time and wow is this handy.

It was so nice to be able to just copy/paste this text from an audio recording.
The notes app has transcribed this text from an audio recording: "whether or not you can pull something off, just imagine that you're someone who can. Allow yourself to suspend disbelief and step into the role of someone who already achieved what you're aiming for, by convincing yourself, even temporarily, that you are capable of doing the"

Just in that tiny sample of their huge amount of watch faces I already spotted several that are the kind I want that I never have been able to get with my Apple Watch. 🫠

The Sketch Note workshop that @felibe444.bsky.social put on at @swiftleeds.co.uk was GREAT.

And I'm not just saying that because I won the Lego set! 😂
