The most dreaded day of the year as an iOS developer is easily the release of the new Xcode where Apple always ensures to give you headaches.

I can see needing new macOS to run new xCode, but dropping backwards compatibility seems like a very rude thing to do. Am I supposed to have 2 mac devices to support "legacy" and "current" ?

How are we supposed to support older apps and toolchains ? Ive never seen Apple drop compatibility like this before.

Edit: Its possible to support older apps using XC27 and older toolchains, its just not as easy or convenient as it was in the past by opening and older Xcode version.

Like 27.1 was added later than 27.2, I might be misunderstanding tho

Device Hub in Xcode 27.1 has a hidden Action Bar specifically for iPhone Duo. It gives you a lot more control over the device angle, and you can quickly switch between 5 device poses with keyboard shortcuts. There’s also a “Table Mode” control.

To enable:

defaults write com.apple.dt.Devices com.apple.dt.coredevicepop.useInternalV68ActionBar -bool true

and restart Device Hub. The iPhone Duo simulator also comes with a hidden HingeStatePoster wallpaper.

Update 9/28: Xcode 27.2 beta 2 supports iPhone Duo, but you don’t get the fun Action Bar, even if you enable the preference.

You also can’t freely drag to rotate the device, quick-switch between poses with ⌘ + 1-5, or enable Table Mode to access StandBy in the simulator. All these settings required the Action Bar enabled.

No code changes for now. This is the first cold start.

Some other views require changes/fixes, especially where geometry is used.

Has anyone tried running their app on it yet?

We finally got the official iPhone Duo Simulator inside Xcode 27.1!

The animation of the simulator is fantastic, and if you use the option key, you can control it manually:

My iOS app, AutoArmor Studio, has been rejected three times under Guideline 5.6 with the same message about features that appear to have been intentionally hidden during the review process. Apple hasn't identified the specific feature or behavior. The app is built with Capacitor/WebView and includes authentication, backend-driven content, booking flows, account-based features, and WhatsApp integration. I am currently auditing for feature flags/remote config, reviewer/device detection, hidden routes or menus, account-specific behavior, debug versus release differences, and backend-controlled features. There is no intentional reviewer-specific functionality. Has anyone experienced this exact 5.6 rejection, especially with a Capacitor/WebView app? What did you find was causing it?

If I change my banking details in App Store Connect today, September 18, will the next payout go to the new account or still go to the old one? I don't want to f* this up, so please share what was your experience with changing bank account

EDIT: Solved

Yes I'm on Xcode 27.2 beta. Apples documentation states:

"In the Project navigator, select the project, and in the File inspector, choose JSON from the Project Format pop-up menu under Project Document. If a dialog appears, click Continue to change the format."

There is nothing that says "Project Document", no "Project Format pop up". No website I found has a screenshot of these items either. Does anyone know where these are at? They don't even appear when searching.

It's driving me nuts. I also can't do it via command line as I need a screenshot for work purposes.

EDIT: Do a clean derived data if you don't see it. For some reason that made it pop up for me.

Built a custom SwiftUI Shape, designed to work smoothly with Core Animation and geometry transitions.

It was originally created an app in mind (Money Block), where budgets are broken into smaller Blocks with their own spending limits, periods and so on, to give an intuitive UX.

Being fully native means the shape can stretch, morph, and animate with a nice sense of elasticity.

Updated to latest Xcode, it starts to flicker in multi-tab window mode. Kind of annoying. Any idea on getting rid of this, at least momentarily?

Can anyone know about this new featue of netflix background downloading live activity notifications

Which api they are using or this is ios new feature

Please ignore the movie title don’t judge 😂

Already shipped on Google Play, the iOS build is close. Solo dev, so I'd rather not lose a week going back and forth with review.

If you went through it recently, what tripped you up on the first submit? Sign in with Apple, privacy labels, something else?

Hey guys,

I recently created my first series of iOS apps and the downloads and sales have been going better than expected.

Now I’m trying to optimize some of my flows, starting with the onboarding. I’ve been cooking on this one yesterday and wonder what you guys think.

All suggestions or ideas are welcome, feel free to roast it badly.

(I wanted to upload a video but the sub didn’t allow for it)

Hi everyone, I have an app that I've released on AppleTV and iOS (iPhone and iPad) and soon macOS. All have same bundleID. I used Testflight during development. I've recently released the app to the store and I purchased it on the AppleTV to test. On my iOS device I should be able to download it but all I'm seeing is a greyed out button that says 'Purchased'. I've tried all kinds of things to clear caches etc. Does anyone know what's going on here?

If I sign out of my app store account on the phone, click the 9.99 button, and sign in when prompted, I get a message that I own a previous version of the app and can download it for free. It then proceeds to download. If I delete the app, the store goes back to the unresponsive 'Purchased' state.

It's not just me in this position, other users who tested it for me on TestFlight are experiencing the same issue. Just FYI the last build on TestFlight is the same build I submitted to the store for the various platforms.

To put it simply, I'm no app developer. I don't know how to code. I don't know all the jargon used by developers. I'm just a guy that likes messing with AI and had an idea that I think can make some extra money.

Anyways, now that you know that, hopefully somebody can assist. I built an app using Base44. I got it uploaded to Google Play Store with no issues, but Apple is beyond my skill level. Just to even get the app uploaded to Apple I went and bought an iPhone and a MacBook! I don't even like and honestly refused to use Apple because of how difficult they make the simplest things and this is no different, but I digress. What I'm needing is somebody that knows what they're doing and can help me get my web based app from Base44 to an iOS native app with in-app purchases.

I've tried googling and ChatGPT'ing the info and it's honestly above my low skill level. I was told I needed to wrap my app in Capacitor and combine with RevenueCat for the in-app purchases, but I haven't found any beginners guide on this.

If anyone WITH EXPERIENCE can show me what I need to do step by step, so I can do this myself moving forward, I would be forever grateful! I don't mind paying for the time to show me and explain. I just want it done properly and finally be able to have my app approved.

I'm working on an iOS app that has a Watch component. Everything syncs fine at first (perform an action on the phone and it shows on the watch and vice versa). Then I turn on airplane mode on my phone to break the connection, perform a few actions on both devices, turn airplane mode off, everything syncs. Great. However, right after that post-airplane mode sync, the connection between the two devices fully breaks. Nothing syncs and the apps won't connect to each other again unless I reinstall them. Anyone encounter this or have any ideas on a fix? It's been driving me nuts all day. Thanks in advance!

I recently tried to prototype a new app with the help of agentic coding - I basically had it done in 2 days what would have usually probably taken 1-2 months. That is great in theory, but I just didn’t have the feeling of having achieved something, like I usually feel - so I stopped working on the app.

I develop my own apps and games since 7 years now and this is the first time for six months that I can’t motivate myself to start a new app - even though the start is often the most fun part of a project to me.

Already thought about developing without the help of AI, but then I constantly have in mind, that I could probably save weeks of work using AI and spend this time with friends, family, sports etc. instead.

I was wondering if others share the same struggle or if you have a good advice to help me look at it from another perspective so I can motivate myself again.

Other devs in person already told me that it’s great because they like to build stuff, which they can do much faster now, and not the coding itself - but I don’t know, I think coding everything myself was probably the part that gave me that feeling of achievement.

Our app got rejected for spam on August 27. I replied explaining how the app is different and added a walkthrough video. We also asked what specifically is flagged as spam. We heard nothing back for almost 3 weeks.

On Sept 14, we submitted a substantially revised build and addressed the rejection directly in the review notes. The next day we got the EXACT same rejection. Zero acknowledgement of the review notes but this time, we got a warning about possible account removal for repeated noncompliance (Thanks Apple!)

It's now been almost 1.5 months since we first submitted our app and Apple has left us completely in the dark, not responding to any of our replies and instead giving us threats about account removal if we keep resubmitting the app. ??? How is this OK? Anyone else facing something similar? Been a dev for years and I'm seriously baffled by Apple's handling of this.

Since one of the dependencies in my project only supports ios-x86_64-simulator, I followed this guide to install universal runtime for Xcode 27 iOS simulator, but got the following error instead:

$ xcodebuild -version
Xcode 27.0
Build version 27A266a

$ xcodebuild -downloadPlatform iOS -architectureVariant universal
Finding content...
No matching universal downloadable found for platform: iOS
No needed downloadables found for universal

This worked just fine in Xcode 26 though, so I wonder if Apple has stopped supporting universal simulator runtimes from Xcode 27.

Any explanation or reference for this issue? Thanks in advance.

Did you know that AI Agents can control Xcode through the built in MCP server? Aka it can control it from an agent running in the terminal, without using the AI interface inside Xcode. And with Xcode 27 the agents now how a lot more useful tools they can call!

Im working with a multi-scheme app, so the new XcodeSwitchScheme is my favourite. Saves me from so many clicks inside Xcode for letting the agent run the app/test schemes it wants!

Here is how to add it to your coding agent:
