The largeTitle of UINavigationBar disappears after scrolling on iOS 26.1
My project uses the UINavigationController's largeTitle on the latest iOS 26.1, but I found that when I set the backgroundColor, the navigation bar's largeTitle disappeared after switching between normal and large titles. I checked the latest documentation and consulted AI, but I have not found any good solutions. For the demo project, please refer to FB20986869

Reply to Xcode 16 warning about missing symbols of static framework
The only way out of it was to create a build post-action script to generate the missing dsym file. Here is the gist of the script: set -euo pipefail if [ -z ${ARCHIVE_PATH:-} ]; then exit 0 fi APP_PATH=$ARCHIVE_PATH/Products/Applications/App_Product_Name.app if [ ! -d $APP_PATH/Contents ]; then exit 0 fi BIN=$APP_PATH/Contents/Frameworks/Framework_Name.framework/Framework_Name OUT=$ARCHIVE_PATH/dSYMs/Framework_Name.framework.dSYM OUT_DWARF=$OUT/Contents/Resources/DWARF/Framework_Name if [ ! -f $BIN ]; then exit 0 fi if [ ! -f $OUT_DWARF ]; then mkdir -p $ARCHIVE_PATH/dSYMs rm -rf $OUT xcrun dsymutil $BIN -o $OUT fi if [ ! -f $OUT_DWARF ]; then exit 1 fi BIN_UUIDS=$(xcrun dwarfdump --uuid $BIN | awk '{print $2}' | sort) DSYM_UUIDS=$(xcrun dwarfdump --uuid $OUT_DWARF | awk '{print $2}' | sort) if [ $BIN_UUIDS != $DSYM_UUIDS ]; then exit 1 fi

WatchOS: Can a background metronome app coexist with both Runna workout and Spotify playback?
I’m building a standalone Apple Watch metronome app for running. My goal is for these 3 apps to work at the same time: Runna owns the workout session Spotify plays music my app plays a metronome click in the background So far this is what I've found: Using HKWorkoutSession in my metronome app works well with Spotify, but conflicts with Runna and other workout apps, so I removed that. Using watchOS background audio with longFormAudio allows my app run in the background, and it can coexist with Runna. However, it seems to conflict with Spotify playback, and one app tends to stop the other. Is there any supported watchOS audio/background configuration that allows all 3 at once? More specifically this is what I need: another app owns HKWorkoutSession Spotify keeps playing my app keeps generating metronome clicks in the background Or is this simply not supported by current watchOS session/background rules? My metronome uses AVAudioEngine / AVAudioPlayerNode with generated click audio. Thank you!

Unable to Verify App... again 😐
Unable to Verify App An internet connection is required to verify trust of the developer Apple Development: John Doe (ABCXYZ123). This app will not be available until verified. I've been getting this constantly over the last few weeks. It has been a real struggle to get anything done. Sometimes it goes away on its own after I try to launch the app a few times, but currently it's just staying down and I can't do any work. Apparently there were issues with some Apple server ppq.apple.com before. They seem to be back, because trying again right now: ping ppq.apple.com PING use1-ppq-ext-prod.apple.com (17.33.200.235): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 ^C --- use1-ppq-ext-prod.apple.com ping statistics --- 3 packets transmitted, 0 packets received, 100.0% packet loss ping apple.com PING apple.com (17.253.144.10): 56 data bytes 64 bytes from 17.253.144.10: icmp_seq=0 ttl=60 time=9.776 ms 64 bytes from 17.253.144.10: icmp_seq=1 ttl=60 time=8.726 ms ^C --- apple.com ping stat

App stuck in “Waiting for Review” for 10+ days (Case ID: 102845134369)
App Review App Store Connect Hi everyone, My iOS app has been stuck in “Waiting for Review” for over 10 days, and I’m starting to worry there might be an issue with my submission or account. Here are the key timeline details (GMT+7): Feb 3, 2026 – Submitted app → entered Waiting for Review Feb 5, 2026 – App went In Review and was later Rejected by Apple Feb 5 – Mar 2, 2026 – I made fixes and resubmitted Then on Mar 2, 2026: Submitted again → Waiting for Review On Mar 8, 2026: I made several quick re-submissions (Developer Rejected → Ready for Review → Waiting for Review multiple times within minutes) Since then: Mar 8, 2026 → Today (Mar 18, 2026) Status has remained “Waiting for Review” with no progress I have already contacted Apple Developer Support: Case ID: 102845134369 However, I haven’t received any meaningful update yet. My concerns: My app was previously reviewed (reached In Review and got feedback), so it doesn’t seem like a completely new or blocked app. The app itself is relatively simple (no sensi

Reply to CloudKit: Efficient way to get user's rank in leaderboard without fetching all records?
Thank you for the response! I think there may be a slight misunderstanding of my question. I am already linking each LeaderboardScore record to a user via a reference field. My challenge is how to efficiently calculate and determine the user’s rank, since I am not storing a rank field in the records and instead compute it client-side. Please see attached photo for visual reference. Current Implementation Fetch LeaderboardScore records sorted by score (descending): let query = CKQuery(recordType: LeaderboardScore, predicate: predicate) query.sortDescriptors = [NSSortDescriptor(key: score, ascending: false)] Assign rank based on position in the sorted results: entries = scores.enumerated().map { index, score in score.asLeaderboardEntry( rank: index + 1, // Rank assigned client-side isCurrentUser: score.profile.id == currentProfileID ) } This works well when the current user is within the fetched results (e.g., top 15–20). In that case, I can determine their rank directly from the local data. However, if the use

Reply to Xcode 16 warning about missing symbols of static framework
I am seeing a similar issue, but only for my Mac Catalyst archive on XCode 26. My app is a SwiftUI application that embeds an Objective-C framework built from a separate Xcode project. The framework binary itself does have UUIDs, but when I inspect the .xcarchive, the corresponding framework dSYM is missing from the archive’s dSYMs folder. What is confusing is that this does not happen for the iOS build. I use the same framework target, and when I archive the iOS app and upload to TestFlight, I do not get the warning. The problem only appears when I archive the Mac Catalyst version. So in summary: • The embedded framework binary is present in the archive • The framework executable has valid UUIDs • The app archive’s dSYMs folder does not contain the matching dSYM for that embedded framework • This only happens for Mac Catalyst • The same setup works correctly for iOS Has anyone seen Catalyst archives skip generating or packaging dSYMs for embedded frameworks, even though the binary itself contains de

Reply to DriverKit vs MFi for iPad custom hardware serial communication?
> I have a custom hardware board that I want to communicate serially with from an iPad. Should I use the DriverKit route or the MFi route? Depends on exactly what your needs are and the hardware you're working with. Starting with MFi, the biggest advantage is that the software side (ExternalAccessory framework) is far simpler to use and includes support for background access (DriverKit does not). The main downside is that it requires a certain amount of custom hardware and the certification process. Comparing it with DriverKit is... complicated. The software side of DriverKit is FAR more complicated. To start with, the DriverKit API is a somewhat odd derivative of the IOKit kernel API. For someone who's familiar with IOKit, it's similar enough to be understandable, but for a new developer, the learning curve can be quite significant. None of this is helped by the fact that DriverKit is poorly documented[1], to the point that my standard advice to new developers is to study the IOKit kernel API (which has o

Reply to CGSetDisplayTransferByTable is broken on macOS Tahoe 26.4 RC (and 26.3.1) with MacBook M5 Pro, Max and Neo
Thank you for reporting this — it's a clear and well-documented write-up. I was able to reproduce this on a MacBook M5 Max running macOS 26.3.1 (25D2128). I built a small test app that exercises both CGSetDisplayTransferByTable and CGSetDisplayTransferByFormula with several different gamma tables (identity, warm tint, inverted, red-only, gamma 1.8). On the M5 Max: Both APIs return kCGErrorSuccess Reading back the table with CGGetDisplayTransferByTable returns the correct values that were just set No visual change occurs on the display The same test app works correctly on an M5 (non-Max) machine running the same macOS build — all gamma changes are immediately visible on screen. This suggests the gamma tables are being stored correctly at the CoreGraphics level, but are not being applied to the display pipeline on M5 Max hardware. Tested on both built-in and external displays. I've related your two bugs (FB22273730 and FB22273782) together and attached the sample project I used to reproduce the problem

Quick questions for xcode cloud build
We're investigating using xcode cloud to do our CI builds. We have our own on-prem self-managed GitLab behind a private firewall. Some questions on this: I see some IP's for Apple here: https://developer.apple.com/documentation/xcode/setting-up-your-project-to-use-xcode-cloud#Use-a-remote-source-control-repository Do these IP's ever change? Are there specific ports Apple uses? Would be nice to limit to only what's needed. Do we have to open in-bound access or can we instead have our builds reach out with an outbound only setup?

Reply to Using StoreKit from an AUv3 plugin that can be loaded in-process
BTW, however I solve this, if I do, it needs to work on both Mac OS and iOS - I have no idea if there's much market for iOS Audio Units, but it was easy enough to build for both, so I will release both. It's at least likely to be a less saturated market :-)
