If I install RealmSwift into an ios app using SPM, I have no problems. However if I install it into an ios framework, then when building there is this error: error: missing required modules: 'Realm.Private', 'Realm', 'Realm.Swift' I have discovered that if I change the import statement from: import RealmSwift to private import RealmSwift then doing that makes this build error goes away (but doing that isn't a feasible workaround as I would like to publicly export classes stored in Realm from the framework). There's no point in posting issues with Realm on their support board as its being deprecated and its tumble weeds on their forum. But I would be very interested in hearing from the Apple expects explanation or speculation on: why is importing the same framework via SPM into a framework xcode project resulting in different behavior then when importing it into an app? why would changing import to private import make the build error go away? TIA

Hello, I used to add openssl static libraries (libssl.a, libcrypto.a) that, I created on Mac, and add them after to my C++ project within XCode. With Xcode 14.2 (and before) all works fine. Switching to Xcode 15.2, tons of link errors rise (ld: Undefined symbols). I tried _ld_classic to force use 'old' linker but no success. Rebuild the static libraries with multiple config param or upgrade to recent openssl library does not help. Any clues what went wrong when linking static libraries with Xcode 15.2 project? Thx.

I have a SwiftUI RealityKit app, and I am writing UI tests for it. The app has entities that have children. All entities have an accessibilityComponent so that they can be found by UI tests. If I set isAccessibilityElement = true for the parent, the UI tests find the parent. If I set isAccessibilityElement = false for the parent, and isAccessibilityElement = true for the child, the UI tests find the child. If I set isAccessibilityElement = true for the parent as well as for the child, the UI tests find only the parent. How can I make parent and child entities both be accessible by the UI tests?

I am getting this error in a couple of places in my code with Task closure after setting Swift 6 as Language version in XCode. Passing closure as a 'sending' parameter risks causing data races between code in the current task and concurrent execution of the closure Below is minimally reproducible sample code. import Foundation final class Recorder { var writer = Writer() func startRecording() { Task { await writer.startRecording() print("started recording") } } func stopRecording() { Task { await writer.stopRecording() print("stopped recording") } } } actor Writer { var isRecording = false func startRecording() { isRecording = true } func stopRecording() { isRecording = false } } While making the class Recorder as Actor would fix the problem, I fear I will have to make too many classes as Actors in the class and in my scenario, there could be performance implications where real time audio and video frames are being processed. Further, I don't see any race condition in the code above. Does the error talk about possible race conditions that could arise if I were to call other functions on the self in future, or the current code itself is not safe?

Within Xcode's settings location section is a drop down menu to switch between setting the derived data location to be default, relative or custom. However its a global setting. I work on more than one project simultaneously, and for one of them I want the location set to relative, but default for all the others. Is there any way of achieving that?

Hello. We have a few iOS devices connected to CI macs. We test our 3D engine, so we really need hardware devices for that. The issue is that Xcode loses connection to the devices once in a while, mostly after mac reboot, which requires a human to enter test room and unplug and plug cable again. Even if device is visible and accessible in Finder, Xcode may still don't see it, and devicectl shows it as disconnected. Are there any hacks to make connection stable? The best what we could achieve so far was to remove iOS device screen lock - otherwise mac reboot would in 100% cases require human interaction to reconnect the device. Both iOS and mac are logged into the same Apple ID. Mac is logged in automatically after reboot iOS devices have no screen lock Thank you.

I tried dragging an apns file for a live activity into my simulator to begin a Live Activity. It didn't do anything. I didn't see it mentioned in the wwdc videos either. So I'm wondering if this experience is not yet developed, or maybe I'm doing something incorrectly?

ive been using the mac m1 for almmost a year and it used to run vision pro simulator on xcode 15 quite smoothly but now its quitting unexpectedly showing errors in loading the realtiykit content

Hi. I have a xcframework that has a dependency on 'RxSwift' and 'RxCocoa'. I deployed it using SPM by embedding it in a Swift Package. However when I import swift package into another project, I keep getting the following error: "Missing required module 'RxCocoaRuntime" How can I fix this? Below are the steps to reproduce the error. Steps Create Xcode proejct, make a dependency on 'RxSwift' and 'RxCocoa' (no matter doing it through tuist or cocoapods) Create XCFramework from that proejct. (I used commands below) xcodebuild archive \ -workspace SimpleFramework.xcworkspace \ -scheme "SimpleFramework" \ -destination "generic/platform=iOS" \ -archivePath "./SimpleFramework-iphoneos.xcarchive" \ -sdk iphoneos \ SKIP_INSTALL=NO \ BUILD_LIBRARY_FOR_DISTRIBUTION=YES xcodebuild archive \ -workspace SimpleFramework.xcworkspace \ -scheme "SimpleFramework" \ -archivePath "./SimpleFramework-iphonesimulator.xcarchive" \ -sdk "iphonesimulator" \ SKIP_INSTALL=NO \ BUILD_LIBRARY_FOR_DISTRIBUTION=YES xcodebuild -create-xcframework \ -framework "./SimpleFramework-iphoneos.xcarchive/Products/Library/Frameworks/SimpleFramework.framework" \ -framework "./SimpleFramework-iphonesimulator.xcarchive/Products/Library/Frameworks/SimpleFramework.framework" \ -output "./SimpleFramework.xcframework" Embed in Swift Package, and deploy. // swift-tools-version: 6.0 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "SimplePackage", platforms: [.iOS(.v16)], products: [ .library( name: "SimplePackage", targets: ["SimplePackage"]), ], dependencies: [ .package(url: "https://github.com/ReactiveX/RxSwift", from: "6.8.0") ], targets: [ .binaryTarget( name: "SimpleFramework", path: "Sources/SimpleFramework.xcframework" ), .target( name: "SimplePackage", dependencies: [ "SimpleFramework", "RxSwift", .product(name: "RxCocoa", package: "RxSwift") ] ) ] ) Download Swift Package in another project and import module. I resolved this by removing dependencies from the Swift Package, downloading package in another project, and fetching dependencies by cocoapods. Thist works, but I don't want to use another dependency manager while using SPM. Development Environment CPU : Apple M4 Max MacOS : Sequoia 15.3 Xcode : 16.2

Hello! I'm experiencing a persistent SwiftCompile warning that I haven't been able to resolve for several months: <unknown>:0: warning: default will never be executed Observations: Appears randomly across different files during the build. No source location or line highlighting is provided. Persists across clean builds and project reopenings. Occurs in both Xcode Cloud and local builds. What I’ve tried: Ensuring all switch statements on enums explicitly handle every case. Removing default cases from fully covered enum switches. Refactoring optional enum handling (e.g., using if let instead of switch). None of these resolved the issue. Any guidance would be greatly appreciated! Project details: Xcode: 16.2 Swift: 6 iOS Target: 17.0+ UI: SwiftUI-only (no UIKit) Dependencies: SwiftPM

When I try to build my project in Xcode (from Unity AR) project, it throws me these errors: I feel like I've tried everything to make the LaunchScreen work. I downloaded xcode the night I tried running this build, so the whole deleting and redownloading and restarting everything didn't work. I've tried making sure my macbook and terminal are fully up to date. I literally can't find a solution! Please help!! I will also say, I'm fairly new to App building, Xcode, and Unity. But this does seem like a barrier that is stopping me from testing my project.

I'm having trouble compiling my project for the iOS 18.2 simulator. I'm getting the following error: `Missing '#include <sys/_types/_time_t.h>'; 'time_t' must be declared before it is used` The error points to to simulartor-iOS 18.2 > user/include/sys/_types/_time_t.h #ifndef _TIME_T #define _TIME_T #include <machine/types.h> /* __darwin_time_t */ typedef __darwin_time_t time_t; #endif /* _TIME_T */ This suggests that the time_t type should be defined, but the compiler isn't seeing it. I suspect there might be a problem with preprocessor definitions. Is there anything I set wrong? I am using OpenSSL.xcframework.

We are renaming the project and a Static Library the is critical to the operation on the app is not found during compiling. We have the same project working fine. We have reviewed the project.pbxproj file and searched for erroneous linking, reviewed the Target settings and there is nothing obviously wrong. (Copied and secured the original) Typically workflow is: Clean Delete Derived Data dir D/l Swift Packages Build/Run The team has many years using Xcode / Swift and the project and this is not clear how to resolve. We have scoured SO and the solutions do not apply. Facts: -No cocoapods -Search Paths all set Linker all set Thoughts?

In my Swift app, Xcode has decided to put various important settings like, SWIFT_VERSION under "User Defined." Does anyone know why?

Hi! When I run my project on a real device (iPhone 15 Pro), I encounter the following error: Build input file cannot be found: '/Users/Interexy/Library/Developer/Xcode/DerivedData/SinglePhotoBook-geecnphrjebsisdmhcyzlsefvphm/Build/Products/Debug-iphoneos/SinglePhotoBook.app/SinglePhotoBook'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it? How can I solve this? I've already reinstalled Pods and cleaned DerivedData a million times, but the issue persists. Xcode: Version 15.4

Hi, You're here because your project has issues related to Xcode Previews or Swift Previews. The issue you're experiencing may be the result of any of the following: An error in your SwiftUI app, Xcode previews, or on-device previews. A configuration error in your Xcode project, including any third-party dependencies or packages. A system issue in the operating system, SwiftUI, or in Xcode Previews. Based on your request, I need more information about your SwiftUI app when rendering Xcode Previews or on-device previews. Specifically, I’ll need the diagnostics Swift Previews generates to make sure I understand the error encountered by the preview system. Please create a report in Feedback Assistant to share the details requested in the instructions below. For issues with macOS, Mac Catalyst, on-device iOS, or on-device visionOS previews, perform the following steps to gather diagnostics: Download and install the Swift Previews logging profile for your device. Reproduce the error while previewing on device, taking note of the timestamp when the error occurred. Attach the Previews diagnostics, sysdiagnose from your Mac, a sysdiagnose from the previewing iOS or visionOS device. For issues with Xcode Previews, perform the following steps to gather diagnostics: Download and install the Swift Previews logging profile for your device. Reproduce the error in Xcode Previews, if you haven’t already done so. If an error banner appears in the canvas, click the "Diagnostics" button within the banner, then go to Step 5; otherwise, continue to Step 4. If the error banner is missing, navigate to the menu in Xcode: Editor > Canvas > Diagnostics In the presented sheet, click the "Generate Report" button. Attach a zip file containing the diagnostic report to your bug report (it will be named something like previews-diagnostics-0123456789.zip). Submitting your feedback Before you submit to Feedback Assistant, please confirm the following information is included in your feedback: with the Swift Previews logging profile installed, attach the sysdiagnose logs gathered after reproducing the issue the Previews diagnostics generated by Xcode timestamp identifying when the issue was reproduced focused sample Xcode project that reproduces the issue (if applicable) screenshots or videos of the error (optional) Please include all requested information to prevent delays in my investigation. After your submission to Feedback Assistant is complete, please respond to your original Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your SwiftUI app, a configuration issue within your Xcode project, or an underlying issue in the operating system, SwiftUI, in Xcode Previews, or on-device previews.

What I want? I expect to use xcrun devicectl device process launch --device <uuid> <bundle-identifier> --payload-url <URL> to launch my app and pass the specified URL as I usually do in iPhone. What I do? Let's say the app A which I'm developing. I try to use UIApplication.open(:options:completionHandler:) in another app to open the app A with registered schema. And whether app A is cold launch or background resumption, app A can go foreground with receiving URL. If I use xcrun devicectl as above described, app A can still be opened. However, app A can't receive URL which I pass through --payload-url option. That's different from in iOS. BTW: I as well try YouTube with UIApplication.open and xcrun devicectl, the former way work, the latter way not work.

Debugger on Xcode 16.x is super slow and it turns out it's only this way when Xcode is connected to my iPhone via WiFi. If I disable WiFI on my iPhone everything is just fine. But that's not a solution. An engineer posted this supposed solution, https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes. Forgive me but that's not a solution, especially since we used to be able to shut off "Connect via WiFI." I've seen so many posts here and everywhere else with no one stating any clear answer. Does anyone know why has this been removed? And is anyone aware of it? I've posted in the Feedback Asst. as many others have. What gives?
