Hello all! Trying to find list of all XCode project parameters or build settings within description. Is there any documentation? Need something that will help me to understand list of project properties when running command in project folder: $ xcodebuild -showBuildSettings Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -showBuildSettings User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES Build settings for action build and target test: ACTION = build AD_HOC_CODE_SIGNING_ALLOWED = NO AGGREGATE_TRACKED_DOMAINS = YES ALLOW_BUILD_REQUEST_OVERRIDES = NO ALLOW_TARGET_PLATFORM_SPECIALIZATION = NO ALTERNATE_GROUP = staff ALTERNATE_MODE = u+w,go-w,a+rX ALTERNATE_OWNER = alexandr ALTERNATIVE_DISTRIBUTION_WEB = NO ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = NO ALWAYS_SEARCH_USER_PATHS = NO ALWAYS_USE_SEPARATE_HEADERMAPS = NO and may other parameters Need to know meaning of this kind of parameters.

According to the ARM documentation for the CPU models available in Apple Silicon, the CoreSight implementation includes an Embedded Trace Macrocell which can perform a complete Instruction Trace (https://developer.arm.com/documentation/102119/0200/What-is-trace-). Although other operating systems such as Linux make this easy, we have not been able to find any tools or even a system-level API for accessing this feature of the ETM. In the Instruments window of Xcode 16+, there is a Processor Trace instrument, but this performs sampling and is totally unrelated to the Instruction Trace we need for debugging and analysis purposes. Because it produces a complete, contiguous sequence of branch instructions, the Instruction Trace is essential for identifying precise execution behaviors that are otherwise invisible to the developer. On other platforms, an alternative is debugger scripting, but we have found far too many bugs and reliability issues with the macOS implementation of lldb. Any suggestions would

I've been playing with the new GameSave API and cannot get it to work. I followed the 3-step instructions from the Developer video. Step 2, Next, login to your Apple developer account and include this entitlement in the provisioning profile for your game. seems to be unnecessary, as Xcode set this for you when you do step 1 First add the iCloud entitlement to your game. Running the app on my device and tapping Load starts the sync, then fails with the error Couldn’t communicate with a helper application. I have no idea how to troubleshoot this. Every other time I've used CloudKit it has Just Worked™. Halp‽ Here is my example app: import Foundation import SwiftUI import GameSave @main struct GameSaveTestApp: App { var body: some Scene { WindowGroup { GameView() } } } struct GameView: View { @State private var loader = GameLoader() var body: some View { List { Button(Load) { loader.load() } Button(Finish sync) { Task { try? await loader.finish() } } } } } @Observable class GameLoader { var directory: G

GKAccessPoint triggerAccessPointWithState handler not invoked on iOS 26.0 and iOS 15.8.4 Incorrect/Unexpected Behaviour: When calling [GKAccessPoint.shared triggerAccessPointWithState:GKGameCenterViewControllerStateAchievements handler:^{}] on a real device running iOS 26 beta (iOS 26), the overlay appears as expected, but the handler block is never called. This behavior also not working correctly on previous iOS versions(tested on iOS 15.8.4) Steps to Reproduce: Authenticate GKLocalPlayer Call triggerAccessPointWithState:handler: with a block that logs or performs logic Observe that overlay appears, but block is not executed Behavior: UI appears correctly Handler is not invoked at all Expected Result: The handler should fire immediately after the dashboard is shown. Actual Result: The handler is never called. Usecase: As GKGameCenterViewController is deprecated we are moving to GKAccesspoint but due to above functionality issue we are unable to. Environment: Device: iPhone 16, iPhone 7 iOS: 26.0 and iOS 15.8

Environment iOS Version: iOS 26 Beta 8 Xcode Version: iOS 26 Beta 6 StoreKit: StoreKit 2 Description When calling AppStore.showManageSubscriptions(in:) on iOS 26 beta, I'm experiencing an unusual presentation behavior that wasn't present in earlier versions. An empty/blank view appears first Then the actual StoreKit manage subscriptions sheet appears on top When dismissing the StoreKit sheet, it closes properly But then I have to dismiss the empty view underneath as well This creates a poor user experience showing double sheets. Code Sample @MainActor func showManageSubscriptions() { guard let scene = UIApplication.shared.connectedScenes .first(where: { $0 is UIWindowScene }) as? UIWindowScene else { return } Task { do { try await AppStore.showManageSubscriptions(in: scene) } catch { // Handle error } } } Expected Behavior The StoreKit manage subscriptions sheet should present directly without any intermediate empty view, as it did in previous iOS versions. Actual Behavior An empty view layer appears

I've built an app that supports live activities, but when trying to build and deploy I'm getting the error: Provisioning profile iOS Team Provisioning Profile doesn't include the com.apple.developer.live-activity entitlement. Looking in Xcode - under signing and provisions, there is no Live Activity option to select. Looking in the developer portal, similarly under Certificates, Identifiers & Profiles, there is no Live Activity option. I've added com.apple.developer.live-activity to my entitlements file for both my widget and my main app target, and added NSSupportsLiveActivities to my info.plist files. I'm building on Xcode Version 16.0 Any ideas on how to fix this? Super confused! Thanks in advance!

Development environment Xcode 26.0 Beta 6 iOS 26 Simulator macOS 15.6.1 To verify TLS 1.3 session resumption behavior in URLSession, I configured URLSessionConfiguration as follows and sent an HTTP GET request: let config = URLSessionConfiguration.ephemeral config.tlsMinimumSupportedProtocolVersion = .TLSv13 config.tlsMaximumSupportedProtocolVersion = .TLSv13 config.httpMaximumConnectionsPerHost = 1 config.httpAdditionalHeaders = [Connection: close] config.enablesEarlyData = true let session = URLSession(configuration: config, delegate: nil, delegateQueue: nil) let url = URL(string: https://www.google.com)! var request = URLRequest(url: url) request.assumesHTTP3Capable = true request.httpMethod = GET let task = session.dataTask(with: request) { data, response, error in if let error = error { print(Error during URLSession data task: (error)) return } if let data = data, let responseString = String(data: data, encoding: .utf8) { print(Received data via URLSession: (responseString)) } else { print(No da

Hello! The minimize behavior was working correctly while I was using Xcode 26 beta 4 with iOS 26 beta 4 simulator — when scrolling down, the Tab Bar would minimize as expected. However, after upgrading both Xcode and iOS simulator to beta 5, the tabBarMinimizeBehavior setting no longer has any visible effect — the Tab Bar stays fixed in place. Code snippet: if #available(iOS 26.0, *) { self.tabBarMinimizeBehavior = .onScrollDown } Steps to reproduce: 1. Create a UITabBarController with at least one tab containing a scrollable view (e.g., UITableView). 2. In viewDidLoad, set tabBarMinimizeBehavior to .onScrollDown. 3. Run on iOS 26 beta 5 simulator. Expected behavior (beta 4): Scrolling down hides/minimizes the Tab Bar with animation. Actual behavior (beta 5): Tab Bar remains fixed; no minimize animation is triggered. Environment: • Xcode 26 beta 5 (Build: 17A5295f) • iOS 26 beta 5 simulator (Build: 1055) – iPhone 16 Pro • Also tested on iPhone 13 mini – iOS 26 (Build: 23A5308g)
