My system has run out of application memory(app) - ios

This problem appeared when i wrote Text("Today i made:"............), 68 line and i don't know how to fix it.
My thought, that probably problem with #AppStorage(in HomeView i have same variable.... var savedSalary = Double()). But in this View i decided to write #AppStorage with different variable, i just added one more "y" in the end and wrote(var savedSalaryy: Double = 8.75).
Restart didn't help me too.
Before the reading the code watch this screen
import SwiftUI
struct DayOnWorkView: View {
#State private var ifTapped = false
#State private var startTime = Date()
#State private var timerInt = 0 // was string
#AppStorage("SALARY_KEY") var savedSalaryy: Double = 8.75 // was savedSalary = Double()
let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()
var body: some View {
NavigationView {
ZStack {
BackgroundView()
VStack(alignment: .center) {
Button(action: {
self.ifTapped.toggle()
}, label: {
Image(systemName: ifTapped ? "person.crop.circle.badge.checkmark" : "person.crop.circle.badge.xmark")

How to open custom view and bottom sheet in tabbar views and Subview with sticky bottom tabbar in SWIFTUI?

Given code is for custom bottom tab-bar with plus button in center by using we need to hide and show one detail view and from last tab we are just opens menu from bottom sheet.
Problem :- When we are hide and show a detail view using center button that refresh the ui and redirect us on root from any subview. while we are using bottom sheet that works fine for us.
When we are open bottom sheet in subview that is start view from top of tabbar.

SwiftUI: Longpress Gesture Hold for only 1 Second

Using the Long press gestures on SwiftUI only keep the long press hold gesture for 1 second then automatically releases the long press. I would like for the user to press up to 1 minute or more. Is this possible and how can it be done.
Check out my code below, which currently only supports a 1-second duration long-press gesture.
struct IgnitionDriveView: View {
#GestureState private var drivingGestureState = false
#GestureState private var reverseGestureState = false
#State private var showDriveAlert = true
#State private var showOutOfGasAlert = false
#State var distanceCovered: Float = 1.0
var body: some View {
let circleShape = Circle()
let driveGesture = LongPressGesture(minimumDuration: 1)
.updating($drivingGestureState) { (currentState, gestureState, transaction) in
gestureState = currentState
}.onChanged { _ in
if distanceCovered < 1000 {
self.distanceCovered += 10
} else {
showOutOfGasAlert = true
}
}
let reverseGesture = LongPressGesture(minimumDuration: 1)
.updating($reverseGestureState) { (currentState, gestureState, transaction) in
gestureState = currentState
}.onChanged { _ in
if distanceCovered > 0 {
self.distanceCovered -= 10
}
}
VStack(alignment: .leading) {
Text("Distance Covered in Km: \(distanceCovered)")
.font(.headline)
ProgressView(value: distanceCovered > 0 ? distanceCovered : 0, total: 1000)
.frame(height: 40)
HStack {
ZStack {
circleShape.strokeBorder(style: StrokeStyle(lineWidth: 2))
circleShape
.fill(drivingGestureState ? .white : .red)
.frame(width: 100, height: 100, alignment: .center)
Text("D")
.bold()
.padding()
.foregroundColor(.green)
.font(.title)
}.foregroundColor(.green)
.gesture(driveGesture)
Spacer()
ZStack {
circleShape.strokeBorder(style: StrokeStyle(lineWidth: 2))
circleShape
.fill(reverseGestureState ? .white : .red)
.frame(width: 100, height: 100, alignment: .center)
Text("R")
.bold()
.padding()
.foregroundColor(.red)
.font(.title)
}.foregroundColor(.green)
.gesture(reverseGesture)
}.padding()
}.alert("Press D to Drive and R to Reverse", isPresented: $showDriveAlert) {
Button("Okay") { showDriveAlert = false }
}.alert("You ran out of Gas, Reverse to Gas Station", isPresented: $showOutOfGasAlert) {
Button("Sucks, but fine!") { showOutOfGasAlert = false }
}
.padding()
}
}
here is a very basic approach that you can build on, based on the code in:
https://adampaxton.com/make-a-press-and-hold-fast-forward-button-in-swiftui/
struct IgnitionDriveView: View {
#State private var timer: Timer?
#State var isLongPressD = false
#State var isLongPressR = false
#State private var showDriveAlert = true
#State private var showOutOfGasAlert = false
#State var distanceCovered: Float = 0.0
private func circleShape(isPressed: Binding<Bool>) -> some View {
Button(action: {
if isPressed.wrappedValue {
isPressed.wrappedValue.toggle()
timer?.invalidate()
}
}) {
ZStack {
Circle().strokeBorder(style: StrokeStyle(lineWidth: 2))
Circle().fill(isPressed.wrappedValue ? .white : .red)
}.frame(width: 100, height: 100, alignment: .center)
}
}
var body: some View {
VStack(alignment: .leading) {
Text("Distance Covered in Km: \(distanceCovered)").font(.headline)
ProgressView(value: distanceCovered > 0 ? distanceCovered : 0, total: 1000).frame(height: 40)
HStack {
ZStack {
circleShape(isPressed: $isLongPressD)
.simultaneousGesture(LongPressGesture(minimumDuration: 0.2).onEnded { _ in
isLongPressD = true
timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true, block: { _ in
if distanceCovered < 1000 {
distanceCovered += 10
} else {
showOutOfGasAlert = true
}
})
})
Text("D").bold().padding().foregroundColor(.green).font(.title)
}.foregroundColor(.green)
Spacer()
ZStack {
circleShape(isPressed: $isLongPressR)
.simultaneousGesture(LongPressGesture(minimumDuration: 0.2).onEnded { _ in
isLongPressR = true
timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true, block: { _ in
if distanceCovered > 0 {
distanceCovered -= 10
}
})
})
Text("R").bold().padding().foregroundColor(.blue).font(.title)
}.foregroundColor(.green)
}.padding()
}.alert("Press D to Drive and R to Reverse", isPresented: $showDriveAlert) {
Button("Okay") { showDriveAlert = false }
}.alert("You ran out of Gas, Reverse to Gas Station", isPresented: $showOutOfGasAlert) {
Button("Sucks, but fine!") { showOutOfGasAlert = false }
}
.padding()
}
}
The LongPressGesture is updating after the minimum time no matter if the user lifts its finger or not. Take a look here on how to register to the onEnded even which I guess is what you want to wait for. i.e when the user takes his/hers finger off screen - https://developer.apple.com/documentation/swiftui/longpressgesture

Very weird bug where sheet cover is not working in Swift iOS 14.1-ios 14.4 but working for iOS 14.5 and above

this bug has been scratching my head for the past few days and I still don't know why the problem is arising and what the fix is. I have a camera screen and integrated it with the TOCropViewController (https://github.com/TimOliver/TOCropViewController) to allow a user to select a picture from their photo library and crop it to show a new post. For some reason the image picker is detecting that it should change the view to the ImagePicker from the camera view screen but it's not displaying it on ios14.4 and below but it works just fine for iOS 14.5 and above.
Here is my camera view code:
struct CameraView: View {
#StateObject var model = CameraModel()
#State var currentZoomFactor: CGFloat = 1.0
#StateObject var registerData = RegisterViewModel()
#StateObject var newPostData = NewPostModel()
enum SheetType {
case imagePick
case imageCrop
case share
}
#State private var currentSheet: SheetType = .imagePick
#State private var actionSheetIsPresented = false
#State private var sheetIsPresented = false
#State private var originalImage: UIImage?
#State private var image: UIImage?
#State private var croppingStyle = CropViewCroppingStyle.default
#State private var croppedRect = CGRect.zero
#State private var croppedAngle = 0
#StateObject var userData = UserViewModel()

I would greatly appreciate any help on how to get the ImagePicker view to show up for iOS 14.1-ios 14.4 I've been scratching my head since I worked on it assuming anything that works on iOS 14.5 and above should work on below but only this specific ImagePicker is not working as intended. Thanks!

Date Picker Button / Swiftui

I've created a date picker but don't know how to place the buttons under it.
Can you do that?
swiftui i am learning new.
I have attached the sample Design image.
I want the same as in the picture.
#State private var zaman = Date()
#State private var tarihGorun = false
#State private var tarih = "Tarih Seçiniz"
DatePicker("",selection: $zaman,displayedComponents: .date).labelsHidden()
.accentColor(.white)
.frame(width: 300, height: 50, alignment: .center)
.font(Font.system(size: 25, design: .default))
.padding(5)
.font(Font.system(size: 15, weight: .medium, design: .serif))
.overlay(
RoundedRectangle(cornerRadius: 30)
.stroke(Color(red: 45 / 255, green: 0 / 255, blue: 112 / 255), lineWidth: 1))
.onTapGesture {
self.tarihGorun = true
}
if tarihGorun {
HStack{
Button(action:{
let zamanFormatter = DateFormatter()
zamanFormatter.dateFormat = "MM/dd/yyyy"
let alinanTarih = zamanFormatter.string(from: self.zaman)
self.tarih = alinanTarih
self.tarihGorun = false
}){
Text("Tarih Seç")
}
Button(action:{
self.tarihGorun = false
}){
Text("Kapat").foregroundColor(Color.red)

When a button is pressed, I want the modal sheet to transition from the bottom edge of the device to the centre of the screen, which I have somewhat accomplished. However, the animation somewhat fails when dismissing the modal view, as seen in the provided video, and I'm having difficulties figuring out why this is.
The animation of the modal view I'm using is
.animation(Animation.spring().speed(1.5))
.transition(.move(edge: .bottom))
For the sake of completion, here is my modal view:
struct AddEventView: View {
#State var eventName: String = ""
#State var endDate = Date().addingTimeInterval(60)
#State var gradientIndex: Int = 0
#EnvironmentObject var model: Model
let existingEvent: Event?
let linearGradients: [LinearGradient] = Gradient.gradients.map {
LinearGradient(
gradient: $0,
startPoint: .topTrailing,
endPoint: .bottomLeading
)
}
/// This closure is invoked when the view is dimissed, with a newly created Event passed as its parameter.
/// If the user cancelled this action, `nil` is passed as the parameter
let onDismiss: (Event?) -> Void
var body: some View {
print("Redrawing AddEventView")
return VStack(spacing: 30.0) {
HStack {
Spacer().frame(width: 44)
Spacer()
Text(existingEvent == nil ? "Create Event" : "Edit Event")
.font(.title3)
.bold()
Spacer()
Button(action: {
onDismiss(nil)
}) {
Image(systemName: "xmark.circle.fill")
.imageScale(.large)
}
.frame(width: 44)
}
.padding(.bottom, 5)
.padding(.top, 8)
HStack {
Text("Name of Event").padding(.trailing, 20)
TextField("My Birthday", text: $eventName)
.frame(height: 35)
}
DatePicker(
"Date of Event".padding(toLength: 19, withPad: " ", startingAt: 0),
selection: $endDate,
in: Date()...
)
.frame(height: 35)
ColorChooser(
linearGradients,
selectedIndex: $gradientIndex
)
.frame(height: 75)
Button(action: {
let adjustedEnd = Calendar.current.date(bySetting: .second, value: 0, of: endDate)
let event = Event(
name: eventName,
start: existingEvent?.start ?? Date(),
end: adjustedEnd!,
gradientIndex: gradientIndex
)
onDismiss(event)
}) {
RoundedRectangle(cornerRadius: 13)
.frame(maxWidth: .infinity)
.frame(height: 42)
.overlay(
Text(existingEvent == nil ? "Add Event" : "Edit Event")
.foregroundColor(.white)
.bold()
)
.padding(.horizontal, 1)
}
.padding(.top, 8)
.disabled(self.eventName.isEmpty)
}
.padding(.all, 16)
.background(Color.white)
.cornerRadius(16)
.shadow(radius: 16)
.onAppear {
if let event = existingEvent {
self.eventName = event.name
self.endDate = event.end
self.gradientIndex = event.gradientIndex
}
}
}
}
and my ContentView:
struct ContentView: View {
#State var progress: Double = 0.0
#State var showModal: Bool = false
#State var showPopover: Bool = false
#State var modifiableEvent: Event?
#State var now: Date = Date()
#State var confettiView = ConfettiUIView()
#EnvironmentObject var model: Model
let timer = Timer.publish(every: 1, on: .current, in: .common).autoconnect()
let columns: [GridItem] = Array(repeating: GridItem(.flexible(), spacing: 10), count: 2)
var alertButtons: [Alert.Button] {
return Model.SortableKeyPaths.map { key, _ in
.default(Text(key)) { model.sortedKey = key }
}
}
func onEventEnd() {
self.confettiView.emit(with: [.text("🎉")])
AudioManager.shared.play("Success 1.mp4")
let taptics = UINotificationFeedbackGenerator()
taptics.notificationOccurred(.success)
}
var grid: some View {
LazyVGrid(columns: columns, spacing: 10) {
ForEach(model.events, id: \.self) { event in
SmallCardView(event: event)
.contextMenu {
Button(action: {
modifiableEvent = event
withAnimation {
self.showModal = true
}
}) {
Text("Edit")
Image(systemName: "slider.horizontal.3")
}
Button(action: {
model.removeEvent(event)
}) {
Text("Delete")
Image(systemName: "trash")
}
}
.animation(.linear)
}
if !showModal || modifiableEvent != nil {
AddEventButtonView() {
modifiableEvent = nil
self.showModal = true
}
} else {
Spacer().frame(height: 100)
}
}
.navigationBarTitle(Text("My Events"), displayMode: .large)
.navigationBarItems(
leading: Button(action: { }) {
Image(systemName: "ellipsis")
.imageScale(.large)
},
trailing: Button(action: { self.showPopover = true }) {
Image(systemName: "arrow.up.arrow.down").imageScale(.large)
}
.actionSheet(isPresented: $showPopover) {
ActionSheet(
title: Text("Sort Events"),
buttons: alertButtons + [.cancel()]
)
}
)
}
var body: some View {
return ZStack {
NavigationView {
ScrollView {
grid.padding(.horizontal, 16)
}
.padding(.top)
}
.brightness(self.showModal ? -0.1 : 0)
.blur(radius: self.showModal ? 16 : 0)
.scaleEffect(self.showModal ? 0.95 : 1)
if self.showModal {
AddEventView(existingEvent: modifiableEvent) { event in
if let event = event {

self.model.addEvent(event)
}
withAnimation {

}
}
.padding(.horizontal, 16)
.zIndex(1.0)
.animation(Animation.spring().speed(1.5))
.transition(.move(edge: .bottom))
}
EmptyView().id("\(self.now.hashValue)")
}
.overlay(
UIViewWrapper(view: $confettiView)
.edgesIgnoringSafeArea(.all)
.allowsHitTesting(false)
)
.onReceive(timer) { _ in
if !showModal { self.now = Date() }
if model.events.contains(where: { -1...0 ~= $0.timeRemaining }) {
onEventEnd()
}
}
}
