Overview

Since this evening (March 10, 2026), I'm unable to launch any developer-signed app on my physical device (iPhone 16 Pro Max, iOS 26.4 beta 23E5223k). The error is: "Unable to launch [app] because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user." On the device itself, it shows: "Unable to Verify App - An internet connection is required to verify the trust of the developer." What I've tried: Created a new Apple Development certificate Deleted and reinstalled the app Restarted the device Tested on both Wi-Fi and cellular Confirmed Developer Mode is enabled Removed all third-party CA certificates from the device Verified the code signature is valid (codesign -dv shows correct Authority chain) The root cause: https://ppq.apple.com is currently returning 502 Bad Gateway. I confirmed this both from my Mac (curl -s -o /dev/null -w "%{http_code}" https://ppq.apple.com → 502) and from Safari on the device. This affects all developer-signed apps, not just a specific project. Is anyone else experiencing this? Is there an ETA for the fix? Environment: Xcode 26.3 (17C519) macOS 26.3.1 (25D2128) iPhone 16 Pro Max, iOS 26.4 (23E5223k)

I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

Hi everyone, I’m currently experiencing unusually long review waiting times and wanted to ask if others see the same behavior this week. My situation: • App Store update has been in “Waiting for Review” significantly longer than usual • A newly submitted build also seems stuck • TestFlight processing is slower than I normally see • Expedited review request and contact attempts didn’t change the status so far What confuses me is that I still see other apps receiving updates, so I’m unsure whether this is a broader review delay or something submission-specific. I’m not trying to escalate anything — just looking to understand if this is currently affecting more developers. Would really appreciate hearing about your recent experiences. Thanks and good luck to everyone waiting 🙂

I work on an SDK, and one of the ways we distribute it is as a pre-compiled static XCFramework. As far as I know, it’s the nature of a static framework to not contain symbols since the framework will be embedded in the final app binary, and the symbols should then be generated. However, when testing the "Validate" function of the Xcode 16 deployment process, our users are receiving a warning that says the framework does not contain symbols. Is my assumption about static frameworks and symbols incorrect? Could this be a bug in Xcode 16? Should we modify something in our framework to inform Xcode that symbols are not needed?

When creating an icon using icon composer, I cant upload a build to testflight/App Store connect. Running on device from Xcode works fine, but as soon as I archive and upload to App Store Connect, I get an error saying the icon contains an alpha channel

Hello, I have an app that is using iOS 26 Network Framework APIs. It is using QUIC, TLS 1.3 and Bonjour. For TLS I am using a PKCS#12 identity. All works well and as expected if the devices (iPhone with no cellular, iPhone with cellular, and iPad no cellular) are all on the same wifi network. If I turn off my router (ie no more wifi network) and leave on the wifi toggle on the iOS devices - only the non cellular iPhone and iPad are able to discovery and connect to each other. My iPhone with cellular is not able to. By sharing my logs with Cursor AI it was determined that the connection between the two problematic peers (iPad with no cellular and iPhone with cellular) never even makes it to the TLS step because I never see the logs where I print out the certs I compare. I tried doing "builder.requiredInterfaceType(.wifi)" but doing that blocked the two non cellular devices from working. I also tried "builder.prohibitedInterfaceTypes([.cellular])" but that also did not work. Is AWDL on it's way out? Should I focus my energy on Wi-Fi Aware? Regards, Captadoh

In the first Xcode 16 beta, none of my SwiftUI previews work - they all just crash on start up. Has anybody run into this and found a workaround? Have tried all the usual steps of cleaning the project/restarting Xcode.

When I submit the app to TestFlight beta review I get the error show on UI. (I filled all filed info in Beta Infomation) There was an error processing your request. Please try again later I was inspected Safari to see the detailed error and I got the below error. Failed to load resource: the server responded with a status of 422 () and the detailed javascript error componentStack: undefined errorCode: undefined message: "API Response Error: TF_BETA_APP_REVIEW_RESPONSE" stackTrace: "status code: 422 --- api correlation key: NZEKCTWMNANXDZVTRD3V4GNE3U" Anyone can tell me the problem and how to fix it. Many Thanks.

hii submitted app yesterday to review, This morning I was surprised that the application was rejected, Reason 4.3 Design: Spam.And I've introduced an application programmed by myself, and a unique design.This message I receivedGuideline 4.3 - DesignWe noticed that your app provides the same feature set as other apps submitted to the App Store; it simply varies in content or language, which is considered a form of spam.The next submission of this app may require a longer review time, and this app will not be eligible for an expedited review until this issue is resolved.what should I do ?

Hello, I am having a recurring issue using Swift Playgrounds version 4.6.4 on macOS 26.1. Upon opening a file and every other time I start typing in the code section I get a prompt, the image below, two or three times. It doesn't matter if I accept or decline all or some of the prompts, as soon as I start typing on another line I get prompted another two or three times for permission. It appears to me that prompt generates every time the preview pane tries to update. Declining the prompt breaks the preview but accepting the prompt only gets you through a single line of code before it appears again. I believe this issue started after I updated to macOS26.1 as I had not encountered it before. I've also opened other files with Swift Playgrounds and encounter the same problem. It could also be unrelated to the update and could be an issue with some permission setting somewhere, however, I have been unable to find what or where it could be. Is anyone else experiencing this? Thank you for your time :)

Starting today, we have been seeing this error message. This is a blocker for my team and any help is appreciated Things I've investigated: Testflight Apple status page is green Our signing certificate is valid/ unexpired Provisioning profile is valid/ unexpired There are no pending Apple account agreements Doesn't seem to matter if user also is a member of my company's Apple Business Manager developer team Cellular data is turned off Date/ time is correct User was unable to install app using a personal gmail account and unregistered device User was able to use Testflight to install a third-party app outside of our corporate account Uninstalling/ reinstalling Testflight didn't help

We have a custom SecurityAgentPlugin that is triggered by multiple authorizationdb entries. Some customers report that the SecurityAgent process takes window focus even though no UI or windows are displayed. Our plugin explicitly ignores the _securityAgent user and does not show any UI for that user. However, in macOS 26.1, it appears that the plugin still causes the SecurityAgent to take focus as soon as it is triggered. Is this a change in macOS 26.1 or a bug? Can we do anything to prevent "focus stealing"?

I added a Content Filter to my app, and when running it in Xcode (Debug/Release), I get the expected permission prompt: "Would like to filter network content (Allow / Don't Allow)". However, when I install the app via TestFlight, this prompt doesn’t appear at all, and the feature doesn’t work. Is there a special configuration required for TestFlight? Has anyone encountered this issue before? Thanks!

Hi there, Starting with iOS 26.2 RC, all my DeviceActivityMonitor.eventDidReachThreshold get activated immediately as I pick up my iPhone for the first time, two nights in a row. Feedback: FB21267341 There's always a chance something odd is happening to my device in particular (although I can't recall making any changes here and the debug logs point to the issue), but just getting this out there ASAP in case others are seeing this (or haven't tried!), and it's critical as this is the RC. DeviceActivityMonitor.eventDidReachThreshold issues also mentioned here: https://developer.apple.com/forums/thread/793747; but I believe they are different and were potentially fixed in iOS 26.1, but it points to this part of the technology having issues and maybe someone from Apple has been tweaking it.

Hello everyone, I’m currently experiencing unusually long wait times for app reviews and wanted to check if others are seeing similar delays this week. Here is the current status of my submissions: App Store Update: Stuck in "Waiting for Review" much longer than the typical 24–48 hour window. New Version: A newly submitted version also seems to be stalled in the initial phase. TestFlight Processing: Even TestFlight builds are taking longer than usual to process. Expedited Review: I've attempted an expedited review request and direct communication, but the status remains unchanged so far. What’s confusing is that I see other apps in the same category receiving updates, so I’m unsure if this is a localized technical glitch or a broader delay affecting a specific group of developers. I’m not looking to escalate anything just yet; I’m simply trying to gauge if this is a widespread issue at the moment. I would greatly appreciate any insights into your recent experiences or if you've noticed similar patterns over the last few days. Thanks in advance, and good luck to everyone with pending submissions! 🙂

A user of my app reported that when my app copies files from a QNAP NAS to a folder on their Mac, they get the error "Result too large". When copying the same files from the Desktop, it works. I asked them to reproduce the issue with the sample code below and they confirmed that it reproduces. They contacted QNAP for support who in turn contacted me saying that they are not sure they can do anything about it, and asking if Apple can help. Both the app user and QNAP are willing to help, but at this point I'm also unsure how to proceed. Can someone at Apple say anything about this? Is this something QNAP should solve, or is this a bug in macOS? P.S.: I've had users in the past who reported the same issue with other brands, mostly Synology. import Cocoa @main class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ aNotification: Notification) { let openPanel = NSOpenPanel() openPanel.canChooseDirectories = true openPanel.runModal() let source = openPanel.urls[0] openPanel.canChooseFiles = false openPanel.runModal() let destination = openPanel.urls[0] do { try copyFile(from: source, to: destination.appendingPathComponent(source.lastPathComponent, isDirectory: false)) } catch { NSAlert(error: error).runModal() } NSApp.terminate(nil) } private func copyFile(from source: URL, to destination: URL) throws { if try source.resourceValues(forKeys: [.isDirectoryKey]).isDirectory == true { try FileManager.default.createDirectory(at: destination, withIntermediateDirectories: false) for source in try FileManager.default.contentsOfDirectory(at: source, includingPropertiesForKeys: nil) { try copyFile(from: source, to: destination.appendingPathComponent(source.lastPathComponent, isDirectory: false)) } } else { try copyRegularFile(from: source, to: destination) } } private func copyRegularFile(from source: URL, to destination: URL) throws { let state = copyfile_state_alloc() defer { copyfile_state_free(state) } var bsize = UInt32(16_777_216) if copyfile_state_set(state, UInt32(COPYFILE_STATE_BSIZE), &bsize) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } else if copyfile_state_set(state, UInt32(COPYFILE_STATE_STATUS_CB), unsafeBitCast(copyfileCallback, to: UnsafeRawPointer.self)) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } else if copyfile(source.path, destination.path, state, copyfile_flags_t(COPYFILE_DATA | COPYFILE_SECURITY | COPYFILE_NOFOLLOW | COPYFILE_EXCL | COPYFILE_XATTR)) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } } private let copyfileCallback: copyfile_callback_t = { what, stage, state, src, dst, ctx in if what == COPYFILE_COPY_DATA { if stage == COPYFILE_ERR { return COPYFILE_QUIT } } return COPYFILE_CONTINUE } }

Not quite but maybe sorta related to the errOSAInternalTableOverflow problem I asked about in a different thread, this one deals with crashes our app gets (and much more frequently lately after recent OS updates (15.7.3) are OK'd by our IT department). Our app can run multiple jobs concurrently, each in their own NSOperation. Each op creates its own SBApplication instance that controls unique instances of InDesignServer. What I'm seeing recently is lots of crashes happening while multiple ops are calling into ScriptingBridge. Shown at the bottom is one of the stack crawls from one of the threads. I've trimmed all but the last of our code. Other threads have a similar stack crawl. In searching for answers, Google's AI overview mentions "If you must use multiple threads, ensure that each thread creates its own SBApplication instance…" Which is what we do. No thread can reach another thread's SBApplication instance. Is that statement a lie? Do I need to lock around every ScriptingBridge call (which is going to severely slow things down)? 0 AE 0x1a7dba8d4 0x1a7d80000 + 239828 1 AE 0x1a7d826d8 AEProcessMessage + 3496 2 AE 0x1a7d8f210 0x1a7d80000 + 61968 3 AE 0x1a7d91978 0x1a7d80000 + 72056 4 AE 0x1a7d91764 0x1a7d80000 + 71524 5 CoreFoundation 0x1a0396a64 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 6 CoreFoundation 0x1a03969f8 __CFRunLoopDoSource0 + 172 7 CoreFoundation 0x1a0396764 __CFRunLoopDoSources0 + 232 8 CoreFoundation 0x1a03953b8 __CFRunLoopRun + 840 9 CoreFoundation 0x1a03949e8 CFRunLoopRunSpecific + 572 10 AE 0x1a7dbc108 0x1a7d80000 + 246024 11 AE 0x1a7d988fc AESendMessage + 4724 12 ScriptingBridge 0x1ecb652ac -[SBAppContext sendEvent:error:] + 80 13 ScriptingBridge 0x1ecb5eb4c -[SBObject sendEvent:id:keys:values:count:] + 216 14 ScriptingBridge 0x1ecb6890c -[SBCommandThunk invoke:] + 376 15 CoreFoundation 0x1a037594c ___forwarding___ + 956 16 CoreFoundation 0x1a03754d0 _CF_forwarding_prep_0 + 96 17 RRD 0x1027fca18 -[AppleScriptHelper runAppleScript:withSubstitutionValues:usingSBApp:] + 1036

I accidentally clicked on tvOS instead of iOS for a new build. So now I have a "tvOS Prepare for Submission" item in the left panel of iTunes Connect. I have no plans to make a tvOS version, so is there any way to remove that?

Hi everyone, We're facing an issue with Universal Links on iOS 18 and above. The problem seems related to how iOS handles redirects before reaching a Universal Link. ✅ Working Link (direct): When we open this direct Universal Link, the app opens as expected: 👉 https://dl.punchh.com/deeplinks/logansroadhouse/ ❌ Not Working (redirected link): This marketing/tracking link eventually redirects to the above Universal Link, but on iOS 18+, it opens the App Store or a browser instead of the app: 👉 https://ip2.loyalty.logansroadhouse.com/ls/click?upn=... The same redirect link works fine on iOS 17 and below — it opens the app.

I've been working on an app. It uses iCloud syncing. 48 hours ago everything was working 100%. Make a change on the iPhone it immediately changed on the Mac. Change on the Mac, it immediately changed on the iPhone. I didn't work on it yesterday. I updated to iOS26.4 on the iPhone and 26.4 on the Mac yesterday instead. Today, I pull up the project again. I made NO changes to the code or settings. Make a change on the iPhone it immediately updates on the Mac. Make a change on the Mac, nothing happens on the iPhone. I've waited an hour, and the change never happens. If you leave the iPhone app, then return, it updates as it should. It appears that iCloud's silent notification is to being received by the iPhone. Anyone else having the issue? Is there something new with iOS 26.4 that needs to be adjusted to get this to work? Again, works flawlessly with the Mac, just not with the iPhone.
