just curious about it

I tried to implement ExpressibleByIntegerLiteral to my code and it has been terrible. At last, it asked me to implement this init // Cannot find type 'Builtin' in scope init(_builtinIntegerLiteral value: Builtin.IntLiteral) { }

I have a M2, 13" MacBook Pro import Cocoa import IOKit import Foundation var blob = IOPSCopyPowerSourcesInfo() // cannot find 'IOPSCopyPowerSourcesInfo' in scope

SwiftUI's Refreshing mechanism is driving me crazy. Say that I have this view: NavigationView { List($datasource) { $item in NavigationLink { SubView(item: $item) } label: { Text(item.someAttribute) } } } SubView: TextField("Placeholder", text: $item.someAttribute) And each time I edit the value in the SubView, the SwiftUI's navigation controller retreats the view to the home page(the initial view). Why?

In Safari:

I wrote an app that users can create utilities using terminal commands I'm experiencing a bug that's driving me crazy: I have an array of utilities, and by extension, I made Array<Utility> and Utility RawRepresantable: Part of the declaration for Utility public init?(rawValue: String) {     guard let data = rawValue.data(using: .utf8),           let result = try? JSONDecoder().decode(Utility.self, from: data)     else { return nil }     self = result } public var rawValue: String {     var encoder = JSONEncoder()     encoder.outputFormatting = .prettyPrinted     guard let data = try? encoder.encode(self),           let result = String(data: data, encoding: .utf8)     else {         return ""     }     return result } extension for Array<Utility> extension Array: RawRepresentable where Element: Codable {     public init?(rawValue: String) {         guard let data = rawValue.data(using: .utf8),               let result = try? JSONDecoder().decode([Element].self, from: data)         else { return nil }         self = result     }          public var rawValue: String {         let encoder = JSONEncoder()         encoder.outputFormatting = .prettyPrinted guard let data = try? encoder.encode(self),               let result = String(data: data, encoding: .utf8)         else {             return "[]"         }         return result     } } And now, because of some strange SwiftUI bug (FB11401294) When I pass a binding down a view hierarchy such as List or ForEach they update weirdly. I implement an "edit" feature for my utilities so I will not directly use binding but to call a function that takes an inout of Array<Utility>, the original item, and the item after being edited: func replace(_ sequence: inout [Utility], item: Utility, with replace: Utility) {     var raw = sequence.rawValue     print(raw)     let rawReplaced = raw.replacingOccurrences(of: item.rawValue, with: replace.rawValue)     print(item.rawValue, replace.rawValue)     print(rawReplaced)     sequence = [Utility].init(rawValue: sequence.rawValue.replacingOccurrences(of: item.rawValue, with: replace.rawValue))!     print(sequence) } And the problem is it works and after implementing another completely different feature it stopped working from my debugging, the input of the function is correct and the problem is inside the function. But, as the error seems to be on this line: sequence = [Utility].init(rawValue: sequence.rawValue.replacingOccurrences(of: item.rawValue, with: replace.rawValue))! Now i have completely no idea why this works last time and won't now This line of code works completely well in playgrounds and is now freaking me out Help anyone?

Without dependencies on other third-party frameworks Just a function that receives a string, outputs a string and throws

I have a swiftUI app after I decided to add a document type After I opened the infos tab I clicked on "documents" and Xcode crashed. I've filed a bug (FB10465644). Any way so I added the imported & exported document and now its won't work. I ran the executive in my app and it gave me this: .....frovasvohxblobefzbrrwtvqtyuu/Build/Intermediates.noindex/Previews/UtilityScript/Products/Debug/UtilityScript.app/Contents/MacOS/UtilityScript ; exit; SwiftUI/AppWindowsController.swift:1103: Fatal error [1]    30982 illegal hardware instruction   Saving session...completed.

Can I export a SwiftUI Color / UIKitUIColor / AppKit NSColor to a .clr file? How? Bonus: Can I transfer them to each other?

I add searchable to my SwiftUI List But the search TextField isn't showing Here's my code NavigationView { List(searchResults, id: \.self) { item in NavigationLink { LegendDetailView(item: item) } label: { HStack { Text(item.name).padding(1) Spacer() Image(systemName: "chevron.right").imageScale(.small) } } } }.searchable(text: $searchText)
