Image Not Displaying on Some Devices – Same Code, Inconsistent Behavior
I'm encountering an issue where certain images are not displaying on some iOS devices, while the same code works perfectly on others. There’s no error or crash — just some images fail to load or display. I've confirmed the image URLs and formats are correct. Has anyone faced a similar issue or could suggest what might be causing this inconsistent behavior? Thanks in advance!

Swift/C++ interoperability issue in std::string
In scope of one of our project we've faced an issue with constant crashes when integrating C++ library in Swift code using Swift/C++ interoperability. Investigating the root causes of the issue we've discovered that with new version of Swift bug was introduced. Long story short: for strings bigger than 27 symbols memory is feed incorrectly that causes the crashes. By creating this post I wanted to draw community's attention to the problem and promote it to be solved quicker as for now it is not addressed.

Load bundle resources in UI Tests
I want to load images from my bundle, which works fine when running the main app. However this does not work when running UI Tests. I read that the test bundle is not the main bundle when running tests. I try loading the bundle via this snippet: let bundle = Bundle(for: Frames_HoerspielUITests.self) This is my test class wrapped these the canImport statements so it can be added to the main app target and used for getting the correct bundle: #if canImport(XCTest) import XCTest final class Frames_HoerspielUITests: XCTestCase { override func setUpWithError() throws { continueAfterFailure = false } override func tearDownWithError() throws { } @MainActor func testExample() throws { let app = XCUIApplication() app.launch() } @MainActor func testLaunchPerformance() throws { measure(metrics: [XCTApplicationLaunchMetric()]) { XCUIApplication().launch() } } } #else final class Frames_HoerspielUITests { } #endif However while this works when running the main app, it still fails in the UI tests. It is a SwiftUI only app. and I can't add the images to the asset catalog because they are referenced from another location. Any ideas? Thank you

Customization in Swift ArgumentParser's help command and error output
Hello I want to implement customisation to swift argumentparser, Here are following changes want to do it in my cli changing default footer present in help command output currently help command output coming like this OVERVIEW: clisample USAGE: clisample <subcommand> OPTIONS: --version show the version. -h, --help show the help. SUBCOMMANDS: logs (default) Export logs for clisample processes. See 'clisample --help' for more information.' so instead of See 'clisample --help' for more information.' I want my own string For more details, run 'clisample help <subcommand>' customise error string getting from validation error Error: Missing value for '-t <time>' Help: -t <time> Time window (e.g. 10h, 30m, 2d). Usage: clisample logs --time <time> See 'clisample logs --help' for more information. so I want error output with example and customised footer, like this Error: Missing value for '-t <time>' Help: -t <time> Time window (e.g. 10h, 30m, 2d). Usage: clisample logs --time <time> Example: clisample logs -t 5m For more details, run 'clisample help <subcommand>' Is this changes possible from anyway?

Error `Type of expression is ambiguous without a type annotation` when trying to create a Task.
Hi, I've got this view model that will do a search using a database of keywords. It worked fine when the SearchEngine wasn't an actor but a regular class and the SearchResult wasn't a Sendable. But when I changed them, it returned Type of expression is ambiguous without a type annotation error at line 21 ( searchTask = Task {). What did I do wrong here? Thanks. protocol SearchableEngine: Actor { func searchOrSuggest(from query: String) -> SearchResult? func setValidTitles(_ validTitles: [String]) } @MainActor final class SearchViewModel: ObservableObject { @Published var showSuggestion: Bool = false @Published var searchedTitles: [String] = [] @Published var suggestedKeyword: String? = nil private var searchTask: Task<Void, Never>? private let searchEngine: SearchableEngine init(searchEngine: SearchableEngine) { self.searchEngine = searchEngine } func search(_ text: String) { searchTask?.cancel() searchTask = Task { guard !Task.isCancelled else { return } let searchResult = await searchEngine.searchOrSuggest(from: text) ?? .notFound guard !Task.isCancelled else { return } await MainActor.run { switch searchResult { case let .searchItems(_, items): showSuggestion = false searchedTitles = items.map(\.title) suggestedKeyword = nil case let .suggestion(keyword, _, items): showSuggestion = true searchedTitles = items.map(\.title) suggestedKeyword = keyword case .notFound: showSuggestion = false searchedTitles = [] suggestedKeyword = nil } } } } }

Swift Package file - resources .copy rule with nested directories
Does anyone know if the resources .copy rule in a Swift .package file is supposed to recursively copy the full contents if it's pointed at a directory? The docs say… If you pass a directory path to the copy rule, the compiler retains the directory’s structure. …but you can interpret that in a few different ways. It also doesn’t appear to work if the directory you specify only contains directories.

vDSP.DiscreteFourierTransform failed to initialize with 5 * 5 * 2^n count
I am implementing the FFT using vDSP.DiscreteFourierTransform. According to the official documentation, the count parameter has requirements as outlined below: /// The `count` parameter must be: /// * For split-complex real-to-complex: `2ⁿ` or `f * 2ⁿ`, where `f` is `3`, `5`, or `15` and `n >= 4`. /// * For split-complex complex-to-complex: `2ⁿ` or `f * 2ⁿ`, where `f` is `3`, `5`, or `15` and `n >= 3`. /// * For interleaved: `f * 2ⁿ`, where `f` is `2`, `3`, `5`, `3x3`, `3x5`, or `5x5`, and `n>=2`. Despite adhering to these specifications in theory, my attempt to initialize an interleaved DFT with count = 2 * 2 * 5 * 5 (equivalent to 5×5 × 2²) resulted in a failure. Below is the code snippet I used for the initialization: do { let dft = try vDSP.DiscreteFourierTransform( previous: nil, count: 2 * 2 * 5 * 5, direction: .forward, transformType: .complexReal, ofType: DSPComplex.self ) print(dft) } catch { print("DFT init failed:", error) } Could somebody more knowledgeable with these APIs have a look? Thanks!

Data Disappeared
Hi, writing a database app for storing equipment details. Spent the day doing minor changes and tidying with many backups made, and always re-building to check its all working. Everything ok but then next build looses all data, what's the best thing to check to see if the data is still there, any help would be fantastic.

PHP and Swift interoperability
With Swift being brought to new places, is anyone working on interoperability with PHP? I'd love to replace much of my PHP and Javascript web code with Swift (and ideally SwiftUI for UI design). Are there any projects/people working in this space?
