Reply to CKQuerySubscription on public database never triggers APNS push in Production environment
Hi Ziqiao, thanks for looking into this! I've verified using CKFetchSubscriptionsOperation.fetchAllSubscriptionsOperation() on both Development and Production (TestFlight) devices. All 5 subscriptions are present and correctly configured in both environments. The output is identical between both environments. Here are all 5 subscriptions as returned by CKFetchSubscriptionsOperation: fr-sub-v3 (FriendRequest) Predicate: receiverID == [userID] AND status == pending badge=true, sound=default, contentAvail=false locKey=FRIEND_REQUEST_BODY, locArgs=[senderUsername] category=FRIEND_REQUEST, desiredKeys=[senderID, senderUsername] rec-sub-v3 (MediaRecommendation) Predicate: receiverID == [userID] AND status == pending badge=true, sound=default, contentAvail=false locKey=RECOMMENDATION_BODY, locArgs=[senderUsername, mediaTitle] category=RECOMMENDATION, desiredKeys=[mediaTitle, mediaType, senderID, senderUsername] fs-a-sub-v3 (Friendship) Predicate: userAID == [userID] badge=true, sound=default, contentAvail=false locK

Custom Capacitor 6 plugin with SPM: "plugin is not implemented on ios" despite being compiled
Hi everyone, I'm building an iOS app using Capacitor 6 with Swift Package Manager (SPM). I have a custom native plugin (AppleIAPPlugin) for StoreKit 2 In-App Purchases that lives in the App target (not as an SPM package). Despite compiling successfully, the JavaScript bridge throws: AppleIAP plugin is not implemented on ios Setup AppleIAPPlugin.swift: swift import Foundation import Capacitor import StoreKit @objc(AppleIAPPlugin) public class AppleIAPPlugin: CAPPlugin, CAPBridgedPlugin { public let identifier = AppleIAPPlugin public let jsName = AppleIAP public let pluginMethods: [CAPPluginMethod] = [ CAPPluginMethod(name: getProducts, returnType: CAPPluginReturnPromise), CAPPluginMethod(name: purchase, returnType: CAPPluginReturnPromise), CAPPluginMethod(name: restorePurchases, returnType: CAPPluginReturnPromise), CAPPluginMethod(name: getCurrentEntitlements, returnType: CAPPluginReturnPromise), CAPPluginMethod(name: openManageSubscriptions, returnType: CAPPluginReturnPromise), ] @objc func getProducts(_ call

Xcode 26.4 cannot run app-hosted unit tests on physical iOS 16 devices ("Logic Testing Unavailable")
Summary: After upgrading to Xcode 26.4, app-hosted XCTest execution on physical devices running iOS 16 fails at test-planning time with Logic Testing Unavailable. The same project and same device work under Xcode 26.2. The failure reproduces with a standalone minimal Xcode project, which suggests this is an Xcode regression rather than a project-configuration issue. Environment: Xcode: 26.4 (17E192) macOS: Tahoe 26.4 Failing device: iPhone 11 (iPhone12,1), iOS 16.0.3 Working comparisons: Xcode 26.2 + same iPhone 11 (iOS 16.0.3): works Xcode 26.4 + iPad Pro 11-inch (4th generation) on iOS 26.3: works Regression: Yes. Works on Xcode 26.2. Fails on Xcode 26.4. Same project, same signing setup, same physical iOS 16 device. Minimal reproduction: A minimal sample project with: one iOS app target one app-hosted unit-test target one UI-test target (for comparison; not required to reproduce) Steps for the unit-test repro on a physical dev

Reply to How to uncheck "Connect via network" on physical device in Xcode 15
I guess that's nice of them to intend to break debugging over USB. I'm still hoping they'll intend to, perhaps, add a new feature to allow unchecking the box to Connect via network, which disables using TCP/IP and re-enables debugging over USB as it used to work. Edit: I now see Xcode 26 has removed the checkbox for devices with iOS >17. I guess my request would now be to put the checkbox back, and enable to to be used with recent iOS releases.

xcodebuild fails if build tool plugins are installed
After having built the SwiftUI project numerous times from Xcode and allowing the plugins after the first build post install using xcodebuild -scheme build fails with: The following build commands failed: Validate plug-in “SwiftLintBuildToolPlugin” in package “swiftlintplugins” Validate plug-in “OpenAPIGenerator” in package “swift-openapi-generator” How are we supposed to grant the plugins permission to run in the CLI?

Text alignment issue in iOS 26.4
There appears to be a serious issue in iOS 26.4 regarding text alignment. All text strings are rendered right-aligned instead of left-aligned, even when explicitly setting the paragraph style to NSTextAlignmentLeft. This behavior is unexpected and seems to indicate a regression in text rendering. Could you please confirm whether this is a known issue in iOS 26.4? I am using the following code in a central function that has been working reliably for years across all my apps. Best regards, Rolf Code: NSMutableParagraphStyle* paragraphLeft = [[NSMutableParagraphStyle alloc] init]; if (paragraphLeft != nil) { paragraphLeft.alignment = NSTextAlignmentLeft; NSDictionary *settings = @{ NSFontAttributeName : font, NSForegroundColorAttributeName : fontclr, NSParagraphStyleAttributeName : paragraphLeft }; [theString drawAtPoint:CGPointMake(x, y - font.ascender) withAttributes:settings]; [paragraphLeft release]; }

Reply to Xcode 26.4 breaks compilation
Since this is a change in behavior between Xcode versions, you absolutely should file this as a bug report. The expression on the line that you cited is really quite something! Make sure to post the FB number here for our reference. Since this is a library you depend on, you should talk to the maintainers to look at breaking that up into smaller statements so that you're able to compile it with Xcode 26.4. If you're using Swift Package Manager to import a library, there is a way you can make local modifications to a package you depend on, which might also be helpful to you here. — Ed Ford,  DTS Engineer

Reply to Upgrading Python that ships with Xcode from 3.9.6
You have the right information: You cannot update the version of Python included with Xcode yourself. If you have a concern to report with the version Xcode is including for its needs, you can file an Xcode bug report through Feedback Assistant. For recent macOS versions, Python is not included with macOS, so any installation you may find in locations like /usr and /opt were installed through other means. — Ed Ford,  DTS Engineer

Reply to Xcode 26.4: Regressions in Intelligence features
Chiming in to say three things: The Oauth token expiration happens to me as well. I can't find an exact pattern, but it seems to happen when I leave Xcode idle for a while. I'll go have lunch, come back, and suddenly I have to sign out and sign back in to Claude Agent. The AI seems to lose itself a lot. It'll begin responding to a prompt, I'll see output in the chat, but then it'll hang at Thinking... for a couple minutes.
