How to create a new asset catalog in a package
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

Connections application with 4,000 pre-sign ups rejected unfairly - 4.3
For the last 2 years, our team at Panda has had one goal in mind: to change the failing connection application industry. The business model is severely flawed - evidenced in decline of users in match group etc (all public info). We are building the only connections app in the market without paid features – "We Don't Play Games”. This in itself revolutionizes a space which currently commodifies human connection; true connections aren’t forged through super-likes, platinum memberships and such pay-to-win models, where users that don’t pay are unfairly disadvantaged. Key Differentiators: Never having paid features 50/50 Male-Female Ratio: Our app will ensure a balanced male-to-female ratio, something not found in other apps, especially in countries like India, where dating apps are dominated by men. This helps create a healthier, more equitable user experience for all genders. In a country like India, how can any connections app succeed with 99.9% men and 0.1% women? Panda Duos: A first-of-its-kind feature where two sets of best friends can match with each other – an industry-first that no other major connections app offers. These elements, along with the app's core ethos, make Panda unique in an otherwise saturated market. The traditional models used by Match Group/Bumble are failing, as shown in their earnings reports, because they rely on a pay-to-win approach that doesn't deliver real value. Given these unique aspects, having received 4,550+ pre sign-ups, and our backing by a top VC, we strongly believe that Panda will offer an entirely different experience to users and remake a failing industry. This is not what Apple stands for, goes against fairness, and undermines the trust and respect that it should have as the only app store for iOS phones.

Are umbrella frameworks possible/discouraged?
I want to release a Framework F, containing several other frameworks (such as Realm, Appetitive, Cocoalumberjack, PhoneNumberKit) for use by app A. According to this article: https://medium.com/@bittudavis/how-to-create-an-umbrella-framework-in-swift-ca964d0a2345 They write, without referencing a source: "Although Apple discourage creating umbrella framework". Is that true, do Apple discourage umbrella frameworks, if so why and is it a very strong discourage or a mild one? If not discouraged, then how can this be achieved with Xcode 16? I've been attempting to follow a few tutorial to achieve this, such as https://medium.com/john-lewis-software-engineering/adding-a-third-party-framework-inside-a-first-party-framework-in-xcode-3ba58cfd08da however so far without any success. This last article mentions the Link Binary With Libraries section, which doesn't exist in Xcode 16. There's the Frameworks, Libraries, and Embedded Content section where I have been attempting to add the frameworks into my Framework F (choosing Embed without Signing). I'm able to successfully build Framework F, but when app A attempts to use it (adding F to the Frameworks, Libraries, and Embedded Content section with option embed and sign, or embed and don't sign, makes no difference) then I get run time errors about the umbrellaed frameworks not being able to be found.

Xcode 16 Build & Archive Error - SPM
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.

Unable to localise CFBundleName on iOS Home Screen in en-US
Hi, I have an app that has a different name in en-GB and en-US. In the past I have created localised InfoPlist.strings files, InfoPlist.strings (English) InfoPlist.strings (English (United Kingdom)) InfoPlist.strings (English (United States)) and added CFBundleName = "Default Name", CFBundleName = "UK Name", and CFBundleName = "US Name", for example to each of the three files respectively. After building/installing/running this has worked as expected; if you set the device language to en_GB the display name on the iOS Home Screen is "UK Name", if you set it to en_AU for example it would be "Default Name" and if you set it to en_US it would be "US Name". Furthermore, when the name appears in system modals the correct name would appear based on locale too. For example, with the device language set to en_US, if you long press the app icon on the iOS home screen and tap Remove App, a modal will appear which says 'Remove "US Name"?'. This no longer appears to work correctly. For that same project having made no changes, simply running it on an iOS 17 or iOS 18 device; with the language set to en_US, the name on the home screen will be "Default Name", however, if you again long press and tap remove app, it will say 'Remove "US Name"'. It works correctly for en-GB. Like I said, I remember this working in the past, so I checked on an old device I have running iOS 15.8.2 as well as a simulator running iOS 15.2 and it does work as expected in both of those cases. I tried to create a new minimal project to see if something had changed and therefore if the setup I have is now incorrect and saw that the preferred method of localization now involves making a string catalog instead of multiple strings files. For a new project; duplicating the setup at the top of this post using a string catalogue file named InfoPlist.xcstrings results in the same incorrect behaviour when setting the device language to en_US. I guess my question is, is this a bug in iOS? Or is it likely that I am doing something wrong here?

App update required Message
Hi all, Can anybody assist in how we make an 'app update required' message appear when somebody opens our current app once we have put an updated version on the app store? Our developers are telling us the way the current app was built does not include a feature that makes it possible for users to see the app update required message. Is there any way we can enable this rather than the current version just crash when somebody opens it with no indication that an update is required? thanks!!

Xcode 16 Automatically Builds & Runs Simulator While Editing Storyboard
I’m experiencing an issue in Xcode 16 where the app randomly builds and runs in the simulator while I’m designing items in the storyboard. Here’s what I’ve tried so far to stop this behavior: Disabled "Show Live Issues" in the General settings Removed all key bindings related to Build & Run in the Key Bindings settings Checked for unintentional shortcut triggers, but nothing seems to be causing it Update XCode from 16.1 to 16.2 Delete Derived Data Despite these actions, Xcode still automatically builds and launches the simulator at unexpected times, disrupting my workflow. Is there any setting or hidden configuration that could be causing this? How can I completely prevent Xcode from running the simulator automatically while editing UI in the storyboard? Would really appreciate any guidance on this!

Help! Golang os.Executable() panic on Xcode16 for iOS app
I have a iOS app using a gobind xcframework library. All went well when using Xcode 15.0 (15A240d), but failed on Xcode 16.2 (16C5032a). It’s confirmed the failure is from only Xcode version difference, all others like source code, lib binary, physical test iPhone all keeping the exact same. After digging, the root comes from golang os.Executable() call (https://pkg.go.dev/os#Executable), which is used in xcframework library. Using Xcode 15.0, os.Executable() returns “/var/containers/Bundle/Application/E80602C7-EFFB-4F1B-9FF8-FBA0E7E3DA76/Runner.app/Runner” as normal. But with Xcode 16.2, os.Executable() panic with err “cannot find executable path”. I’ve checked Xcode&SDK version change history, couldn’t find any clue like relevant permissions restrictions stuff. Could someone please share a hint? Thanks .

Issue using RealmSwift in a framework versus using it in an app
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

App Not Appearing in "Available Apps" List in Watch App
I’ve developed an Apple Watch extension for an existing iOS app. When I run the app on the watch via Xcode using the simulator, everything works fine. However, when I try to install it on my iPhone, the Watch app doesn’t show it in the "Available Apps" list, so I can't install it on the watch. The Apple Watch is connected to my iPhone, and I can see other apps available for installation without any issues. I also created a brand new project with watchOS support to troubleshoot, but the same problem occurred. Any ideas on how to resolve this?

[S:1] Error received: Connection invalidated on empty project
Hello everyone, I'm encountering a persistent issue with my newly created widget project, even though it’s a clean, minimal setup. Every time I try to run the widget on the simulator or a device, I get the following error message: [S:1] Error received: Connection invalidated. I get this error even in a new project (I just created a new one) when I add a widget extension to it. The app itself works fine—no errors—but when I try to install the widget extension, it always shows me this error. Initially, I thought the issue was caused by an incorrect URLSession, but even after creating a clean (default) widget extension, the issue persists. I don’t know what to think anymore. Has anyone encountered this before? It’s completely blocking my progress. Conditions - new project from iOS App template WidgetExtension from template with no changes Iphone 14 pro IOS - 18.3.2

Display Calculated Data in SwiftUI Charts ...
I am trying to discover how to display my application’s calculated Solar Information values in a chart. My application identifies a selected location in MapKit. The application identifies the location’s longitude, latitude, and current time of day. The application calculates the selected location’s NOAA [SOLAR ELEVATION], and the [SOLAR AZIMUTH] for the time of day. The application calculates the data, then stores the calculated values as a [Plist] file within my application’s Document Directory. For the moment, complete with repeated scouring of the Internet, I am not sure how to properly convert, transfer, or create a Structure, required by the chart to display the calculated values. I would like to create the chart once the calculations are complete, but I introduced a Plist to store the calculations for future use, too. The calculated values coincide with the NOAA Solar Calculations, complete to the displayed [h : m : s], whereas I also designed the application to create the [Array of Dictionary Objects] to store the calculated values for each subsequent six minute interval, until the end of the selected location’s day. The calculated values are properly appended to the [Array of Dictionary Objects] after each completed calculation, with data transfer constants. There are 240 calculations per day from [00:06:00 to 23:54:00], presented as a [STRING], complete with the [Elevation] presented as a [DOUBLE]. For example :: The application generates the following [Calculated Array of Dictionary Objects], then recreates, and appends a new Plist in the Document Directory. mySolarElevationDataArrayOfDictionaries :: [(theRequiredTimeOfDay: "00:06:00", theCalculatedElevation: -62.60301082991259), (theRequiredTimeOfDay: "00:12:00", theCalculatedElevation: -62.94818095051292), (theRequiredTimeOfDay: "00:18:00", theCalculatedElevation: -63.245198186807215), (theRequiredTimeOfDay: "00:24:00", theCalculatedElevation: -63.49236786176319), (theRequiredTimeOfDay: "00:30:00", theCalculatedElevation: -63.688223890934175), (theRequiredTimeOfDay: "00:36:00", theCalculatedElevation: -63.831564163806945), (theRequiredTimeOfDay: "00:42:00", theCalculatedElevation: -63.921486675739004), (theRequiredTimeOfDay: "00:48:00", theCalculatedElevation: -63.95741610687708), to the end of the data :: ===> (theRequiredTimeOfDay: "23:54:00", theCalculatedElevation: -60.69355458181633)] The application presents the initial data as follows :: Then presents a compass view to illustrate the results :: I modified the Chart’s [MOCK DATA] from the calculated values to test the Chart’s display in a [SwiftUI Hosting Controller]. For example :: The following Chart Mock Data in a [HourlySunElevation_MockChartData.swift] file is called by the application’s [Content View]. import Foundation struct Value { let theRequiredTimeOfDay: String let theCalculatedElevation: Double static func theSunElevationMockData() -> [Value] { return [Value(theRequiredTimeOfDay: "00:06:00", theCalculatedElevation: -62.60301082991259), Value(theRequiredTimeOfDay: "00:12:00", theCalculatedElevation: -62.94818095051292), Value(theRequiredTimeOfDay: "00:18:00", theCalculatedElevation: -63.245198186807215), Value(theRequiredTimeOfDay: "00:24:00", theCalculatedElevation: -63.49236786176319), Value(theRequiredTimeOfDay: "00:30:00", theCalculatedElevation: -63.688223890934175), Value(theRequiredTimeOfDay: "00:36:00", theCalculatedElevation: -63.831564163806945), Value(theRequiredTimeOfDay: "00:42:00", theCalculatedElevation: -63.921486675739004), Value(theRequiredTimeOfDay: "00:48:00", theCalculatedElevation: -63.95741610687708), to the end of the data :: ===> Value(theRequiredTimeOfDay: "23:54:00", theCalculatedElevation: -60.69355458181633)] The Chart illustrates the Mock Data as follows :: I also created a Struct within the [MySunElevationChart_ViewController] to try to append the calculated data, using the same logic with the Plist data transfer constants, as employed by the [Array of Dictionary Objects] :: struct ChartSolarElevationValues { var theRequiredTimeOfDay: String var theCalculatedElevation: Double // Structs have an implicit [init]. This is here for reference. init(theRequiredTimeOfDay: String, theCalculatedElevation: Double) { self.theRequiredTimeOfDay = theRequiredTimeOfDay self.theCalculatedElevation = theCalculatedElevation //mySolarElevationChartData.append(self) } // End of [init(theRequiredTimeOfDay: String, theCalculatedElevation: Double)] } // End of [struct ChartSolarElevationValues] Unfortunately, the result did not append each subsequent calculation, but continued to create the same calculation as a new distinct object :: NOTE :: I only called three calculations with the Struct test. // NOTE :: To prevent an [ERROR] at [var mySolarElevationChartData = [ChartSolarElevationValues]] since it has an init. // Therefore you must add () at the end of [var mySolarElevationChartData = [ChartSolarElevationValues]] let theData = [ChartSolarElevationValues]() //print("theData :: \(theData)\n") let someData = ChartSolarElevationValues(theRequiredTimeOfDay: TheTimeForDaySunElevation.theTheTimeForDaySunElevation, theCalculatedElevation:VerifyCityLocationSearchRequestCorrectedSolarElevation.theVerifyCityLocationSearchRequestCorrectedSolarElevation) var theData_New = theData theData_New.append(someData) print("theData_New :: \(theData_New)\n") // Prints :: theData_New :: [My_Map.ChartSolarElevationValues(theRequiredTimeOfDay: "00:06:00", theCalculatedElevation: -61.11000735370401)]] // Prints :: [theData_New :: [My_Map.ChartSolarElevationValues(theRequiredTimeOfDay: "00:12:00", theCalculatedElevation: -61.315092082911875)]] // Prints :: [theData_New :: [My_Map.ChartSolarElevationValues(theRequiredTimeOfDay: "00:18:00", theCalculatedElevation: -61.47403413313205)]] So, I am misintepreting the required coding structure to properly append the Elevation Chart, and the Azimuth Chart with the calculated data. I know something is amiss, but for the moment, I do not know how to address this issue. Your suggestions would be welcome ... :] jim_k

Need iOS 18.3.2 Device Support Files for Xcode 14.3.1 on macOS Ventura 13.7.4
Hello everyone, I’m facing an issue with running my app on my iPhone, and I’m hoping someone can help. Here’s my situation: I’m using Xcode 14.3.1 on macOS Ventura 13.7.4. My iPhone is running iOS 18.3.2 (Model: iPhone 14 Pro). When I connect my iPhone to Xcode, I get the error: "Could not locate device support files. You may be able to resolve the issue by installing the latest version of Xcode from the Mac App Store or developer.apple.com." I understand that Xcode 14.3.1 only supports up to iOS 16.4, and my iPhone’s iOS 18.3.2 is much newer. Unfortunately, I cannot update my macOS to Sonoma (14.x) due to hardware limitations, so I cannot install a newer version of Xcode (like 15.x or 16.x) that supports iOS 18.3.2. I’ve tried adding device support files manually, but the repositories I found (e.g., iGhibli/iOS-DeviceSupport and JinjunHan/iOSDeviceSupport) only have files up to iOS 16.4 or 17.3, and they don’t work for iOS 18.3.2. Does anyone have the device support files for iOS 18.3.2 (or a close version like 18.3) that I can add to my Xcode 14.3.1 to make it work with my iPhone? Alternatively, does anyone know a reliable source where I can download these files? Any other suggestions to resolve this issue without upgrading my macOS would be greatly appreciated! Thank you in advance for your help! [Your Name or Username]
