Please tell me requestSceneSessionDestruction: returning a "This functionality is not supported for this device idiom." error on the iPhone Duo is a bug.. My app supports opening additional windows on Mac (viewers), but not on any other device. On iOS/iPadOS I just request a destruction of the new window if the user tries. Anyone got any ideas? #iOSDev #iPhoneDuo #UIKit #Xcode

Apple's help books are barely documented, so I wrote up how I build one out of the same Markdown that feeds my docs site. The trap that cost me an evening: hiutil's CoreSpotlight index only works once Spotlight has imported your help bundle, and that never happens for a debug build out of DerivedData. Use the legacy LSM format instead. pandoc and a ten-line Lua filter do the rest. https://www.lilback.com/mac-help-book-from-markdown/ #macOS #MacDev #Swift #Xcode #iOSDev

#Apple is really trying to push AI with #Xcode 27 "Always" as a default seems like the opposite

Do you want to quickly find the slowest spots in your iOS and Mac app code? If so, the following article shows how to use the Top Functions mode in Instruments to quickly find the slow spots: https://swiftdevjournal.com/posts/top-functions/ #Xcode

XCSSET v40 malware infects macOS developers through poisoned Xcode projects on GitHub, then hides in memory. Unit 42 found 17 modules and Chrome hijacking. #XCSSET #macOS #Malware #SupplyChainAttack #CyberSecurity #Xcode

I finally updated my main laptop to macOS 26. I was hoping to just wait for 27, but, unfortunately work needs to be done. (Apple will only accept apps built with Xcode 26 now, and UIDesignRequiresCompatibility has *unique bugs* so it's time to support liquid glass.) Anyway here's Xcode 26.6 on macOS 26.5.2—the current release version of each. It's borderline unusable; I need to keep the inspector closed now unless I'm actively using it. #MacDev #iOSDev #Xcode

As a certified dark mode hater I have been able to get away with having Xcode in light mode but the code window in a dark theme (which I strangely like). I can import the theme with Xcode 27 but it makes the WHOLE interface dark even though the configuration window correctly uses the selected light mode. FB23456652 #Xcode

Has anyone found a way to avoid the weird sharpening issues on smaller icon elements in iOS 27? #IconComposer #iOS27 #Xcode

My god the predictive code completion model in #Xcode is bad. It hallucinated a parameter to a parameterless function I just wrote.

On a class called Config I have

func transitions() -> [Transition] {
…

Then in another class I wrote:

let transitions =

And it autocompleted to

let transitions = config.transitions(for: config.countdown)

WTF Xcode. At least countdown is an actual property on Config, but WTF.

I have struct TimerState and therefore have struct TimerStateTests. When I'm writing a test and have typed out let ts = TimerState DO NOT AUTOCOMPLETE TO TimerStateTests() WHEN I TYPE (

I really wish there was a way to preview notifications during iOS app development without actually running the app and triggering a notification event. Like some Preview macro or debug framework that you can throw notification info to just to get a rendering of what it will look like. I really don't want to hide a button that actually creates a notification behind #IF DEBUG but it looks like that's what I'll have to do. #Swift #SwiftUI #iOS #Xcode

The #1 question my #SwiftUI students ask my TAs (and me) is how to fix "The Local Repository is Out of Date" error when trying to push from #Xcode to GitHub. I've created this YouTube video illustrating a fix. I hope it helps others.
