I have a couple apps in one git repository. I'd like to have a Swift package in that repo as well, shared by apps. In other words, I don't want a separate repo for the Swift package. I followed the instructions here: https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages It seems to work. I can write code like this in my app: import MyLocalPackage func foo() { myLocalPackageFunc() } I notice that the package is not listed under Project > MyApp > Package Dependencies. I don't really care, as long as I can reuse code between apps. But when I try to add this package code to a 2nd app, I'm at a loss. I tried "Add Package Dependencies" and "Add Local", but that creates a different looking setup than the 1st app. The code is browsable in the project navigator. And when I try to build it says "Missing package product 'MyLocalPackage'. The documentation linked above, which I used for the 1st app, does a "New > Package". I don't want a new package. How can I connect the existing one?

Hi folks, I've been having this issue for the last few months, where Xcode Cloud fails to resolve Swift package dependencies while compiling my builds, seemingly at random. Some of my Xcode Cloud builds will fail after several minutes, with an error log looking like that : xcodebuild: error: Could not resolve package dependencies: failed downloading 'https://dl.google.com/firebase/ios/bin/grpc/1.62.2/rc0/grpcpp.zip' which is required by binary target 'grpcpp': downloadError("The request timed out.") Whenever this happens, I have to manually restart an Xcode Cloud build process (or several builds, since the error can happen multiple times in a row), to the point it's becoming increasingly painful to rely on Xcode Cloud for my workflow. The failing packages are mostly random (meaning, it's not always the same one that Xcode fails to resolve), but they are always publicly accessible, even though I have an environment variable set in my Xcode workflows to retrieve a single Github private dependency (maybe this has some kind of importance). Could anyone tell me if this is an isolated issue, or if I could do anything on my end to resolve this ? Thank you !

Summary I have a SwiftUI Chart that worked correctly in iOS 17, allowing both horizontal scrolling and tap gesture selection. However, in iOS 18, the same exact chart will not allow for both tap gestures and scrolling to work -- it's either we allow scrolling or we allow tap gestures but not both. We have tried everything to try to circumvent this issue but have had to resort to old methods of creating the chart. This is an issue that has negatively impacted our customers as well. Again, the charts were working fine on iOS 17, but on iOS 18 the chart scroll + tap gesture capability is not working. Expected Behavior (iOS 17) Users can scroll horizontally through the chart. Users can tap on data points to highlight them. The selected data point updates when tapped. Observed Behavior (iOS 18) The chart no longer scrolls when chartOverlay with the Tap Gesture is applied. Tap selection still works as expected. Code Snippet Below is the working implementation from iOS 17: private var iOS17ChartView: some View { Chart { RectangleMark( yStart: .value(String(firstLevelAlertBand), firstLevelAlertBand), yEnd: .value("100", 100) ) .foregroundStyle(Theme.Colors.green.opacity(0.15)) RectangleMark( yStart: .value(String(secondLevelAlertBand), secondLevelAlertBand), yEnd: .value(String(firstLevelAlertBand), firstLevelAlertBand) ) .foregroundStyle(Theme.Colors.orange.opacity(0.15)) RectangleMark( yStart: .value("0", 0), yEnd: .value(String(secondLevelAlertBand), secondLevelAlertBand) ) .foregroundStyle(Theme.Colors.red.opacity(0.15)) ForEach(telemetryData, id: \.timestamp) { entry in if let utcDate = dateFormatter.date(from: entry.timestamp) { let localDate = convertToUserTimeZone(date: utcDate) let tankLevel = entry.tankLevel ?? 0 LineMark( x: .value("Date", localDate), y: .value("Tank Level", tankLevel) ) .foregroundStyle(statusColor) AreaMark( x: .value("Date", localDate), y: .value("Tank Level", tankLevel) ) .foregroundStyle(statusColor.opacity(0.50)) PointMark( x: .value("Date", localDate), y: .value("Tank Level", tankLevel) ) .foregroundStyle(selectedDataPoint?.date == localDate ? Theme.Colors.primaryColor : statusColor) .symbolSize(selectedDataPoint?.date == localDate ? 120 : 80) PointMark( x: .value("Date", localDate), y: .value("Tank Level", tankLevel) ) //.foregroundStyle(.white).symbolSize(10) .foregroundStyle(Theme.Colors.white(colorScheme: colorScheme)) .symbolSize(12) } } } .chartXScale(domain: (firstTimestamp ?? Date())...(latestTimestamp ?? Date())) .chartXVisibleDomain(length: visibleDomainSize) .chartScrollableAxes(.horizontal) .chartScrollPosition(x: $chartScrollPositionX) .chartXAxis { AxisMarks(values: .stride(by: xAxisStrideUnit, count: xAxisCount())) { value in if let utcDate = value.as(Date.self) { let localDate = convertToUserTimeZone(date: utcDate) let formatStyle = self.getFormatStyle(for: interval) AxisValueLabel { Text(localDate, format: formatStyle) .font(Theme.Fonts.poppinsRegularExtraSmall) .foregroundStyle(Theme.Colors.black(colorScheme: colorScheme)) } AxisTick() .foregroundStyle(Theme.Colors.black(colorScheme: colorScheme).opacity(1)) } } } .chartOverlay { proxy in GeometryReader { geometry in Rectangle().fill(Color.clear).contentShape(Rectangle()) .onTapGesture { location in let xPosition = location.x - geometry[proxy.plotAreaFrame].origin.x // Use proxy to get the x-axis value at the tapped position if let selectedDate: Date = proxy.value(atX: xPosition) { if let closestEntry = telemetryData.min(by: { abs(dateFormatter.date(from: $0.timestamp)!.timeIntervalSince1970 - selectedDate.timeIntervalSince1970) < abs(dateFormatter.date(from: $1.timestamp)!.timeIntervalSince1970 - selectedDate.timeIntervalSince1970) }) { selectedDataPoint = (convertToUserTimeZone(date: dateFormatter.date(from: closestEntry.timestamp)!), closestEntry.tankLevel ?? 0) if let dateXPos = proxy.position(forX: convertToUserTimeZone(date: dateFormatter.date(from: closestEntry.timestamp)!)), let tankLevelYPos = proxy.position(forY: closestEntry.tankLevel ?? 0) { // Offset the x-position based on the scroll position let adjustedXPos = dateXPos - proxy.position(forX: chartScrollPositionX)! withAnimation(.spring()) { selectedPointLocation = CGPoint(x: adjustedXPos, y: tankLevelYPos - 60) // Offset popup above the point showPopup = true } } } } } } .onChange(of: chartScrollPositionX) { newValue in // Dynamically update the popup position when scroll changes if let selectedDataPoint = selectedDataPoint { if let dateXPos = proxy.position(forX: selectedDataPoint.date) { let adjustedXPos = dateXPos - proxy.position(forX: chartScrollPositionX)! selectedPointLocation.x = adjustedXPos } } } } } Please help!

Hi, first time question. I have a game app that I am trying to include google ads on: import GoogleMobileAds I have the following bit of code: init() { GADMobileAds.sharedInstance().start(completionHandler: { _ in print("✅ AdMob started successfully") }) } That is throwing the following error: OliviasGameApp.swift:9:22 Cannot call value of non-function type 'MobileAds' I have gone through countless troubleshooting, including transitioning to Pods. Is there any help on what I can do to resolve this issue?

我想在我的 Mac OS 项目 （Swift UI） 中添加一个 Package dependency Package，但我只能添加一个 Package Collection，我不能只添加一个单独的包依赖包，我想添加 mysql kit 以使我的项目链接到 Mysql 数据库

I found that when the development tool above Xcode16 ran my app, I opened the suspended inscription function, and then opened the system camera, the content in the suspended window would not be displayed, and the suspended window would have a black screen. However, this phenomenon does not appear on Xcode15.4 development tools, it is the same code, I do not know why

I have a project which contains local packages. One of the packages has an explicit dependency on package A, but the main project also has the same dependency. Both of them are pinned to the exact version at all times. Should I manage "shared" dependencies at the project level for local packages? This seems counter intuitive at first, but this question is originating from me fighting with a "Build service could not create build operation: unable to load transferred PIF: The workspace contains multiple references with the same GUID" error in Xcode 16 (all versions). It happens when I switch branches. Closing and reopening Xcode does resolve the issue, but it's a real flow killer. The guide below doesn't mention dependency graph best practice. https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages Thank in advance.

Hey iOS Dev's, I’m currently working on a Swift Package Manager (SPM) for WireGuard, originally developed by a previous team member. It was working fine in Xcode 15.2, but after upgrading to Xcode 16 and Swift 6, I need to update the SPM to ensure compatibility with my base projects and other projects relying on it. With Apple making Xcode 16 mandatory for app submissions starting April 24, this has become an urgent issue. I’ve searched extensively but haven’t found a working solution yet. Has anyone faced similar challenges with Swift 6 migration and SPM updates? Any insights, best practices, or debugging tips would be greatly appreciated! Let’s connect and collaborate—I’d love to discuss possible solutions! 😊 #iOSDevelopment #Swift6 #Xcode16 #SPM #WireGuard #iOS #Swift #SoftwareEngineering #AppStore

I want to statically link xcframework as binaryTarget in Swift Package, but it is copied into the product as dynamic when the Xcode build. How to use xcframework in SwiftPackage and statically link it into iOS product? The Package.swift content and the project are: The WebP.xcframework is static: The Xcode Build Product's WebP.framework is dynamic:

I’ve been working on a Catalyst version of my iOS apps. Finally everything is working apart from the custom intents the user user to configure the widgets. The config UI loads: And changing settings at this level works. But it can’t load the options for the other settings: “No options were provided for this parameter” I see this crash in the intent: Termination Reason: Namespace DYLD, Code 1 Library missing Library not loaded: @rpath/CocoaLumberjack.framework/Versions/A/CocoaLumberjack Referenced from: <E1BF4CC5-4181-3272-828C-86B1CD1A66BF> /Applications/my.app/Contents/PlugIns/Intents.appex/Contents/MacOS/Intents Reason: , (security policy does not allow @ path expansion) (terminated at launch; ignore backtrace) I have added the Hardened Runtime Capability to the Main App Target, the Widget Target and the Intents Target. I also allowed “Disable Library Validation” just in case. What am I missing?

The flags like #if DEBUG ... endif are dependent on the Active Compilation Conditions. So if they say DEBUG the enclosed code block will be executed, otherwise not. Now I have the phenomenon that a #DEBUG block in a Package does not evaluate these conditions. It rather depends on the name of the configuration used to build. So if I build my app with Active Compilation Condition set to DEBUG, but the configuration name is something like App-Release, the DEBUG block in my Package is not added/executed. The ones which are directly in the project are added. Vice versa if the Compilation Condition say RELEASE but the configuration is called App-Debug the blocks in the Package are added to the compilation, but the ones in the project itself are not It suffices that the config name contains the word Debug for this to happen. E.g. the configuration App-Release-Debug (I know that this would be stupid, but it is for demonstrating purposes) will cause the Packages to include the DEBUG blocks. This happens no matter what you set in the Build Settings of the project and/or target. The Packages are added via GitHub/GitLab Source Control with SPM. Any ideas why this behaves like it does? It doesn't seem like it should...

So I will summary an issue one of our clients has asked us on GitHub: https://github.com/pendo-io/pendo-mobile-sdk/issues/233 Project that is a custom framework that uses different SPM packages (one of them is Binary package), we have our main logic inside that framework and we have different targets that use this framework, everything works on the simulator, but running the app on the actual device provokes a crash saying "Binary framework was not found". We have like 20 other SPM packages that work fine, this is the first one we have an issue with. Please note I understand that SPM will not copy paste the Binary for the magic framework as it does for the apps so I suggested to embed it manually. So my question is what the best(easy) way to do it. Please refer to the following issue for more details: https://github.com/pendo-io/pendo-mobile-sdk/issues/233

I am trying to convert a simple URLSession request in Swift to using NWConnection. This is because I want to make the request using a Proxy that requires Authentication. I posted this SO Question about using a proxy with URLSession. Unfortunately no one answered it but I found a fix by using NWConnection instead. Working Request func updateOrderStatus(completion: @escaping (Bool) -&gt; Void) { let orderLink = "https://shop.ccs.com/51913883831/orders/f3ef2745f2b06c6b410e2aa8a6135847" guard let url = URL(string: orderLink) else { completion(true) return } let cookieStorage = HTTPCookieStorage.shared let config = URLSessionConfiguration.default config.httpCookieStorage = cookieStorage config.httpCookieAcceptPolicy = .always let session = URLSession(configuration: config) var request = URLRequest(url: url) request.httpMethod = "GET" request.setValue("text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", forHTTPHeaderField: "Accept") request.setValue("none", forHTTPHeaderField: "Sec-Fetch-Site") request.setValue("navigate", forHTTPHeaderField: "Sec-Fetch-Mode") request.setValue("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.0.1 Safari/605.1.15", forHTTPHeaderField: "User-Agent") request.setValue("en-US,en;q=0.9", forHTTPHeaderField: "Accept-Language") request.setValue("gzip, deflate, br", forHTTPHeaderField: "Accept-Encoding") request.setValue("document", forHTTPHeaderField: "Sec-Fetch-Dest") request.setValue("u=0, i", forHTTPHeaderField: "Priority") // make the request } Attempted Conversion func updateOrderStatusProxy(completion: @escaping (Bool) -&gt; Void) { let orderLink = "https://shop.ccs.com/51913883831/orders/f3ef2745f2b06c6b410e2aa8a6135847" guard let url = URL(string: orderLink) else { completion(true) return } let proxy = "resi.wealthproxies.com:8000:akzaidan:x0if46jo-country-US-session-7cz6bpzy-duration-60" let proxyDetails = proxy.split(separator: ":").map(String.init) guard proxyDetails.count == 4, let port = UInt16(proxyDetails[1]) else { print("Invalid proxy format") completion(false) return } let proxyEndpoint = NWEndpoint.hostPort(host: .init(proxyDetails[0]), port: NWEndpoint.Port(integerLiteral: port)) let proxyConfig = ProxyConfiguration(httpCONNECTProxy: proxyEndpoint, tlsOptions: nil) proxyConfig.applyCredential(username: proxyDetails[2], password: proxyDetails[3]) let parameters = NWParameters.tcp let privacyContext = NWParameters.PrivacyContext(description: "ProxyConfig") privacyContext.proxyConfigurations = [proxyConfig] parameters.setPrivacyContext(privacyContext) let host = url.host ??

I'm simply trying to use a proxy to route a http request in Swift. I've tried using a URLSession Delegate but that results in the same issue with the iOS menu. proxy format: host:port:username:password When I run the code below I am prompted with a menu to add credentials for the proxy. I closed this menu inside my app and tried the function below again and it worked without giving me the menu a second time. However even though the function works without throwing any errors, it does NOT use the proxies to route the request. I've spent days on this and the only solution I found was using a NWConnection but this is super low level and now I need a shared session to manage cookies. If you want to see the NWConnection solution I made its here func averageProxyGroupSpeed(proxies: [String], completion: @escaping (Int, String) -> Void) { let numProxies = proxies.count if numProxies == 0 { completion(0, "No proxies") return } var totalTime: Int64 = 0 var successCount = 0 let group = DispatchGroup() let queue = DispatchQueue(label: "proxyQueue", attributes: .concurrent) let lock = NSLock() let shuffledProxies = proxies.shuffled() let selectedProxies = Array(shuffledProxies.prefix(25)) for proxy in selectedProxies { group.enter() queue.async { let proxyDetails = proxy.split(separator: ":").map(String.init) guard proxyDetails.count == 4, let port = Int(proxyDetails[1]), let url = URL(string: "http://httpbin.org/get") else { completion(0, "Invalid proxy format") group.leave() return } var request = URLRequest(url: url) request.timeoutInterval = 15 let configuration = URLSessionConfiguration.default configuration.connectionProxyDictionary = [ AnyHashable("HTTPEnable"): true, AnyHashable("HTTPProxy"): proxyDetails[0], AnyHashable("HTTPPort"): port, AnyHashable("HTTPSEnable"): false, AnyHashable("HTTPUser"): proxyDetails[2], AnyHashable("HTTPPassword"): proxyDetails[3] ] let session = URLSession(configuration: configuration) let start = Date() let task = session.dataTask(with: request) { _, _, error in defer { group.leave() } if let error = error { print("Error: \(error.localizedDescription)") } else { let duration = Date().timeIntervalSince(start) * 1000 lock.lock() totalTime += Int64(duration) successCount += 1 lock.unlock() } } task.resume() } } group.notify(queue: DispatchQueue.main) { if successCount == 0 { completion(0, "Proxies Failed") } else { let averageTime = Int(Double(totalTime) / Double(successCount)) completion(averageTime, "") } } } Delegate example class ProxySessionDelegate: NSObject, URLSessionDelegate { let username: String let password: String init(username: String, password: String) { self.username = username self.password = password } func urlSession(_ session: URLSession, task: URLSessionTask, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) { if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodHTTPBasic { let credential = URLCredential(user: self.username, password: self.password, persistence: .forSession) completionHandler(.useCredential, credential) } else { completionHandler(.performDefaultHandling, nil) } } }

I've used SPM to install some dependencies, however for one of them, CocoaLumberjackSwift the Embed section is blank and attempting to click in it doesn't brink up any dropdown menuetc. Why is that, how can I change it or check what its set to if its blank? (Code 16.2)

I created a package using "File > New > Package" and now I want to add a new Asset Catalog to this package. With my package selected in the project navigator I select "File > New > File" but it creates a Swift file instead of showing the Template Selection dialog Ref: https://developer.apple.com/documentation/xcode/managing-assets-with-asset-catalogs#Create-a-new-asset-catalog

Since upgrading from Xcode 15 to 16, we have been experiencing a build error during compilation. Building on Xcode 15 still works with no issues. The error happens only on the first build after a clean. Subsequent builds succeed. This is an issue because our CI process archives the project from a clean slate, and this causes it to fail every time. I will attempt to describe the issue and include information I believe is relevant in this document. The error occurs on this import line within an Objective-C file during the Scan Dependencies step of compiling. This line imports our custom Objective-C to Swift bridging header file - "Swift2Objc.h". Our custom Objective-C to Swift bridging header file is simply wrapping the project’s auto-generated Objective-C to Swift bridging header file - "KWISwift.h". The error is specific to the import of the OfflineServices Swift Package. Specifically, the OfflineServices-Swift.h file - the Swift Package’s auto-generated Objective-C to Swift bridging file. Module JRE not found - the exact error (Also included as text on the bottom of the post) JRE is a third-party library provided to us as an xcframework. It is placed directly into our Swift Package as a binary target. The xcframework itself is composed of .a file and a Headers folder which includes header files and a module.modulemap. The module.modulemap file looks like this.

Swift Package: I have an old objc library, that is added as XCFramework to swift package as a binary target. targets: [ .target( name: "CoreServices", dependencies: ["OldContainer"], path: "CoreServices" ), .binaryTarget( name: "OldContainer", path: "Frameworks/OldContainer.xcframework" ), ] This serves the purpose, it builds fine and able to run on simulator. However this framework is breaking the Xcode previews.

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
