// I have a object "CentralProcesser". I can get the user and system usage of the CPU. I want to get the total.
let system: Double = CentralProcesser.current.usage.system // 10.8746757975 or something like that
let user: Double = CentralProcesser.current.usage.user // 23.24123412424 or something like that
// And now I add them together, right?
let total: Double = system + user // nan
Why?

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?
I know there should be a easy solution to this mess but I JUST CAN'T FIND IT AHHHHHHHHHH
cd ......
error: Build input file cannot be found: '/Users/xxx/Library/Developer/Xcode/DerivedData/ColorLibrary-hakdntgphjogwuawcvuxomfrjzex/Build/Products/Debug-iphonesimulator/ColorKit iOS.app/ColorKit iOS' (in target 'ColorKit iOS' from project 'ColorLibrary')
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)
What I want: I'm learning developing by building a document-based todos app and just want my code to run.
What I get:
My app went stuck every time I open a document
So I create a new project and moved all of my code there
Nothing changes
I think that's because I added Touch Bar support so I clear Touch Bar code off
Still nothing changes, but in the LLDB console there's a message:
2022-06-06 09:17:14.098990+0800 Todos[5747:307926] [default] Failed to get state for list identifier com.apple.LSSharedFileList.ApplicationRecentDocuments Error: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" (Access to list denied) UserInfo={NSDebugDescription=Access to list denied}
And I think there's sth to do with App Sandbox, and I added some File Access configuration.
Nothing changes
Then I realized I forgot to add a development team in the new project
Nothing
ALSO1:
when I changed the Signing Certificate to Development
The message in the LLDB console disappeared.
I couldn't find any reference on it.
ANY HELP IS GREATLY APPRECIATED!!!!!!
The requested version of macOS is not available. Please check if your Mac is compatible with this software.
I remembered there's a message that says that you cannot modify this video or whatever at the end of every session. So, if I trim the video and send it to my friend, is it allowed?
Bonus: where can I find the background music for every daily debrief video (if I can)?
It says there's an error uploading the image so I can't get a image up here in a moment
EDIT AFTER RESTARTING SAFARI:
Oh no still won't work
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

(lldb)
HELP I'VE NEVER THIS BEFORE I JUST WANT TO KNOW IF It"S MY BUG OR SWIFTUI'S
AND I JUST WANT MY APP DONE🫠

just curious about it
OK I'm trying to make a sprite(model.Emmiter) that shoots balls(EnergyBalls) and the balls wont emit at the touch location:
import SpriteKit
import GameplayKit
class Sprites {
var Emmiter: SKSpriteNode = .init(imageNamed: "Emmiter")
}
class GameScene: SKScene {
var model: Sprites = .init()
var Emmiter = Sprites().Emmiter
var playableRect: CGRect = .zer
var lastTouch: CGPoint = .zero
override func didMove(to view: SKView) {
Emmiter.position = CGPoint(x: size.width / 2, y: size.width/* view.frame.minY + 100 */)
print(Emmiter.position)
self.addChild(Emmiter)
}
func touchDown(atPoint pos : CGPoint) {
lastTouch = pos
let rotation = -atan2(
lastTouch.x - Emmiter.position.x,
lastTouch.y - Emmiter.position.y
)
Emmiter.run(
.rotate(
toAngle: rotation,
duration: 0.25
)
)
fireEnergyBall(atPoint: lastTouch)
}
func touchMoved(toPoint pos : CGPoint) {
}
func touchUp(atPoint pos : CGPoint) {
}
func fireEnergyBall(atPoint location: CGPoint) {
let EnergyBall = SKSpriteNode(imageNamed: "Energy")
EnergyBall.position = Emmiter.position
print(EnergyBall.position)
let fly: SKAction = .run {
EnergyBall.run(.move(to: location, duration: 1))
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
EnergyBall.un(.sequence([.scale(to: 0, duration: 0.125), .removeFromParent()]))
}
}
EnergyBall.run(fly)
self.addChild(EnergyBall)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
let rotation = -atan2(
touches.first!.location(
in: self
).x - Emmiter.position.x,
touches.first!.location(
in: self
).y - Emmiter.position.y
)
Emmiter.run(
.rotate(
toAngle: rotation,
duration: 0.25
)
)
fireEnergyBall(atPoint: touches.first!.location(in: self.view))
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
}
override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent?) {
}
override func update(_ currentTime: TimeInterval) {
}
}
