Functional difference betwwen "Date" and "App Download Date" under "Analytics Reports" API
Hello all, I'm currently using Apple Connect API to retrieve download info from my app. Namely I'm using App Store Installations and Deletions under the Analytics Reports API, using an ONGOING request with daily granularity. Unfortunately, the data received is not matching the data from apple store connect UI. Under the functional doc for the report-generated-fields (https://developer.apple.com/documentation/analytics-reports/app-installs), I see the following descriptions: Field Date: Date on which the event occurred. For weekly and monthly instances, this column represents the first day of the week and month, respectively. Field App Download Date: The date on which the app was downloaded onto the device. This field is only populated if the download occurred in the previous 30 days, otherwise it is null. Since I am using daily granularity, could you clarify exactly what is the functional difference between the two fields? Which one should I use to show the metric total downloads per day? Since the f

UIKit bindings no longer working in XCode 26
When I try to create bindings between a xib file and it's associated objective-c source code, xcode no longer autocompletes to either an action or an outlet binding. The little circles in the code editor that would previously indicate bindings are no longer there. I can now only create bindings in the tree heirarchy of the UIKit editor after manually adding IBOutlets to the header files.

iOS 26 — significant location changes & region monitoring no longer relaunching terminated apps
I'm observing significant location changes & region monitoring no longer relaunching terminated apps on iOS 26. Configuration: Deployment target: iOS 17, tested on iOS 26.4.2 UIBackgroundModes: location NSLocationAlwaysAndWhenInUseUsageDescription granted (authorizationStatus = .authorizedAlways) allowsBackgroundLocationUpdates = true Using legacy APIs: startMonitoringSignificantLocationChanges() and startMonitoring(for: CLCircularRegion) NSLocationRequireExplicitServiceSession key is NOT set (relying on implicit service session) Data logged into UserDefaults Observed behavior on iOS 26.4.2: Scenario A — app suspended in background (not force-quit): Both significant location changes and CLCircularRegion exit events deliver reliably for the entire trip. didUpdateLocations and didExitRegion fire as expected with appState = .background. Scenario B — app force-quit by user from App Switcher: Over a 30km / 1-hour drive crossing many SLC distance thresholds and many 2km region boundaries, the app is never relau

xcodebuild test (CLI) does not sync .storekit to storekitd on iOS 26.5 — SKTestSession unusable in CI
On iOS 26.5 simulator runtime, running UI tests via xcodebuild test from the command line does not push the scheme's StoreKitConfigurationFileReference to the destination simulator's storekitd AppGroup Octane container. As a consequence, SKTestSession(configurationFileNamed:) either silently falls through to the production App Store (surfacing a Sign in to Apple Account SpringBoard alert during paywall tests), or throws SKInternalErrorDomain Code=3 Error saving configuration file if you call any SKTestSession instance method. The same project, same scheme, same .storekit file works correctly when launched via Xcode IDE (Cmd+R / Cmd+U) — which uses DVTDevice.handleStoreKitConfigurationSyncForBundleID:configurationFilePath: via an internal IDELaunchSession XPC path that the public xcodebuild CLI does not invoke. This regression makes StoreKit Test unusable in CI for any project using xcodebuild test or xcodebuild test-without-building against an iOS 26.5 simulator. Environment macOS: 26.x Xcode: 26.4.1

[quote='888338022, Madhuri_Ramapure, /thread/826318?answerId=888338022#888338022, /profile/Madhuri_Ramapure'] How do the custom notification buttons … continue to work even after the applications have been manually force-quit or killed? [/quote] I’ve no idea, sorry. I’m not familiar with those products, so I don’t know what those buttons actually do. And even if I did, there’s no guarantee I’d be able to work out how they do it. However, I can offer some general titbits: Removing an app from the multitasking UI is a strong indication from the user that the app should not run in the background again until they manually relaunch it. Some subsystem, like URLSession, honour that request scrupulously; others less so. So the exact behaviour varies by subsystem. And even within a subsystem it changes over time. Testing Background Session Code explains one change in URLSession, but other subsystems have their own unique history. And some stuff that happens in the background doesn’t involve background executi

Follow-up and Escalation Request – App Waiting for Review Since March 27, 2026
Dear Apple App Review Team, I hope you are doing well. I am writing to respectfully request assistance regarding my app review status for the following application: App Name: Lang-Talk : Language Lessons App ID: 6761159353 The app was submitted to App Store Connect on March 27, 2026, and it is still showing “Waiting for Review” after more than two months. I previously contacted Apple Developer Support regarding this issue under: Case ID: 102863904030 I received responses on April 15 and April 21 stating that the app was still in the queue and that there was nothing I could do to speed up the process. However, since then, there has been no progress, no review activity, and no additional communication regarding my submission. Because of the unusually long delay, I also posted a question on the Apple Developer Forums to seek guidance from other developers. In my forum post, I explained that: The app has remained in “Waiting for Review” since March 27, 2026 No rejection or feedback has ever been received

Reply to App Rejection doesn't match what my app is
We have NO exchange features. It does as any other wallet does - sends coins to other wallets. There is no middleman or monetary exchange. Don't file an appeal. Just tell it. Reviewers aren't always right. In fact, they are often wrong. Roughly, two out of three times, they are wrong. Last time, I had a desktop application rejected after they ignored all instructions provided under the App Review Information section. They were given multiple alert messages. But they still managed to play dumb. Its iOS counterpart part was also rejected for the same reason two weeks before. I don't know how things work with the crypt things.

Xcode 26.4 WKWebView evaluateJavaScript
In an Xcode 26.4 + iOS 26.x environment, I called evaluateJavaScript inside webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) and got the following error: Printing description of error: ▿ Optional - some : Error Domain=WKErrorDomain Code=4 A JavaScript exception occurred UserInfo={WKJavaScriptExceptionLineNumber=0, WKJavaScriptExceptionMessage=TypeError: undefined is not a function, WKJavaScriptExceptionColumnNumber=0, NSLocalizedDescription=A JavaScript exception occurred}) However, this worked fine in earlier versions before Xcode 26.4 (> 26.0 and < 26.4, though I do not remember the exact version), still with iOS 26.x. It also works fine in an Xcode 26.4 + iOS 18.x environment. And if I add a slight delay using DispatchQueue.main.asyncAfter in the Xcode 26.4 + iOS 26.x environment, then it works without any issue. So what exactly is going on here? I would really appreciate an explanation.

Reply to CKQuerySubscription on public database failing with BAD_REQUEST in Production — distinct from iOS 26.4 silent-push regression
I don't have an immediate answer just yet, but would like to check the following: Are you testing with a device that is logged in with an iCloud account? Without a valid iCloud account, your app can't write to the CloudKit database. Do you have any special configuration on the security roles (CloudKit Console > Schema > Security Roles), which prevents the your account to write to the database?

Reply to M5 Pro DCP bandwidth allocation: asymmetric 27,400/13,700 Mbps split between dispext0/dispext1 on dual 5K configuration
Is the 27,400/13,700 Mbps asymmetric allocation observed on dual 5K configurations the expected manifestation of the two-pipe architecture described in thread 814201, or a distinct allocation policy specific to dual-display scenarios? Yes, it's the same general issue, though my pipe description there was more of a general analogy, not an engineering-level description. Note that you're driving the first monitor at 144Hz: 5120x2880 @ 144Hz, Maximum Source Bandwidth: 27,400 Mbps, HDR enabled ...which is more than the 120Hz required to drive both monitors at 5K. Is there a configuration approach that allows both displays to receive adequate bandwidth allocation? I believe this would work if a hardware adaptor restricted the first monitor to 120Hz. The WindowServer assertion failure in max_src_rect_width_by_pipes() This is a known issue (r.170248892), but it seems to be tied to monitor hot plug, particularly while the machine is asleep, not display allocation. __ Kevin Elliott DTS Engineer, CoreOS/Hardwar
