build disappears

Goal: To render in an apple vision pro app, the solid-mechanics 3D simulation results coming form an FEA code. Starting point: I have surface vtks with deformations on each node. Each time step has a a mesh with the nodal coordinates. This is straighforward translatable to a usd MeshSequence. Unfortunately, the results cannot be simplified to a scaling o linear transformation as you would do with other game-oriented animations. Tools: Right now, I am using Xcode and reality composer pro (RCP) to build the scenes. Technical limitations: I am aware that RCP can do animations with BlendMesh and skeletons and that MeshSequence is not a problem. Progress: Coverting to the sequence of vtk meshes to a usd MeshSequence is straighforward. This animates correctly in Preview and Blender (see screenshot). I managed to convert from MeshSequence to multiple keys and BlendMesh. This also animates correctly in Blender and preview. Unfortunately, the BlendMesh of multiple blended meshes shows a zero animation time in

After updating my Xcode to the latest, I am unable to download an installed app container from the Xcode Devices screen. This currently works with older versions of Xcode with the same app on the same iPad. This worked with older versions of Xcode on the same MacBook as well (including the Xcode 26 beta before updating to the official release yesterday) The specified file could not be transferred.

I am receiving an entitlement error from stripe terminal SDK when integrating Tap to Pay from apple in the info.plist. Im hoping that someone can give me their input on my error output rather than diving into the stripe sdk to point me in the right direction of something I may have missed with entitlements. I have been approved for tap to pay entitlement and am following the instructions here from apple: https://developer.apple.com/documentation/proximityreader/setting-up-the-entitlement-for-tap-to-pay-on-iphone com.apple.developer.proximity-reader.tap-to-pay

Hey All, Curious if you guys are seeing the same thing for those who are using Interface Builder Files (Xib) i set the line seperator to none and on my app (built against ios 18 on the app store, but doesnt matter if i build it against ios 26, or ios 26.1) when running on iOS 26.1 the line seperator will show even when i set it to None. Funny enough if i just play around with the XIB file and set it to single line and maybe RED color the IB file will show it but when running it its the same old default dark greyish color. BUT if i set the line seperator in CODE either to be none or with single line + red it looks good when running on sim / device. So it seems to be an issue with XIB files not being respected in iOS 26.1 (only) i have submitted a feed back FB20466783, hope this helps any xcode devs / uikit devs. thank you ! (I did post this in the xcode forums, but honestly i think its more of a uikit issue than xcode as the IB File visually looks good when changing)

The issue arises only when the .ipa is uploaded to App Store Connect via Xcode. When attempting to download the app through TestFlight, it crashes. This behaviour is isolated to TestFlight and does not occur in any other environment. To clarify the issue: the build is successfully running in Xcode across all iOS devices and versions without any problems. Additionally, the same production .ipa file downloaded from Firebase is functioning as expected.

Hello everyone, I'm a 2nd-year Computer Science student who's excited to dive into iOS development, and I'd really appreciate some guidance from the experienced developers in this community. MY CURRENT BACKGROUND I have a solid foundation in programming fundamentals through my university coursework (data structures, algorithms, OOP concepts), and I'm familiar with general software development principles. However, iOS development is entirely new territory for me, and I want to make sure I start on the right foot. WHAT I'M LOOKING TO UNDERSTAND Learning Path & Technologies Should I start with UIKit or SwiftUI? I've heard conflicting opinions about this How important is it to learn Objective-C in 2025, or should I focus solely on Swift? Are there any foundational Apple frameworks I should prioritize learning early on? Roadmap & Structured Learning Is there a recommended roadmap or learning sequence I should follow? What skills/topics should I master before moving to more advanced concepts? Should I learn

I have been trying to update an app of which the code base hasn't changed in two years. It still builds fine and runs fine, on simulator and device, but... when uploading it to Testflight I get the error The app contains one or more corrupted binaries. Rebuild the app and resubmit.. I have been rebuilding like a maniac, trying to look at what could be wrong with the binary, I let ChatGPT misguide me on the log files, I think I have tried everything... but to no avail. Any ideas how I could find out what goes wrong?

I’m seeing a strange visual bug in iOS 26 when building chat-style UIs that use an inverted ScrollView or List (via .rotationEffect(.radians(.pi)) and .scaleEffect(x: -1, y: 1)) to anchor messages at the bottom. When I add .ignoresSafeArea() to let the chat bleed behind the navigation bar - the new navigation bar fade (that subtle top-to-bottom gradient Apple added in iOS 26) behaves incorrectly. Instead of fading from the top of the screen toward the nav bar, it fades upward from the bottom of the view, effectively covering the entire screen with the gradient. This only happens when the view is inverted. If I remove .ignoresSafeArea(), the fade looks correct — but then my chat no longer extends behind the nav bar. It looks like the fade effect is being applied in the transformed coordinate space of the inverted scroll view rather than in visual screen space. I haven’t found a reliable workaround besides disabling the fade (which isn’t really possible). Has anyone found a proper solution or a modifie

I have been trying to run the ios build and facing issues since last few days. I installed xcode with ios26 and switched to xcode 16.2 beta and now in xcode16.1. My development is blocked as am hitting errors one after the other. Can you point me to any configuration which works ? My development is blocked and its real pain.

I've been struggling to work with the Storekit framework and specifically to find the current Storefront used by the user of the app. Context : My app needs to behave differently depending on the country of the user. For me relying on Locale.current.region?.identifier does not seem very reliable, the user can change it really easily. I'm trying to use the Storekit framework like so : if let storefront = await StoreKit.Storefront.current{ return storefront.countryCode } As per Apple's Storekit documentation : Use current to determine a customer's current storefront region and offer in-app products suitable for that region. You maintain your own list of product identifiers and the storefronts in which you make them available. But I just can't find out what I need to change in my current configuration to get another country. The code keeps returning my original storefront (which is France) I've tried login in with a sandbox user defined on another country. Changed all settings on my device to another country. Ch
