I'm using Xcode 11.7 and my app is targeted for 13.1 and when changing the State of a property in quick succession the app is crashing to a black screen and then returns to the lock screen.
I'm not getting any crash report on the device and when I hook it up to Xcode I just get the following errors:
2020-09-15 06:42:28.586026-0400 [26842:7830878] XPC connection interrupted
2020-09-15 06:42:28.589083-0400 [26842:7831204] [ServicesDaemonManager] interruptionHandler is called. -[FontServicesDaemonManager connection]_block_invoke
I'm not really sure how to troubleshoot this.

I noticed that with iOS14 navigationlinks and button content show all content as blue. The weird thing is if I pull down slightly on the sheet the colors revert.
Here's a video of what I'm talking about.
https://www.icloud.com/iclouddrive/02Ywhk6SiZn4NhUU45cZ2MNPw#iOS14
I tried using .renderingMode(.original) but that hasn't helped.
Starting in Xcode 12 buttons are causing my code to not compile.
At the basic level it's failing which was not failing in Xcode 11.*.
import SwiftUI
struct Foo1: View {
var body: some View {
VStack {
Button(action: print("How about now?")) {
Text("test")
}
}
}
}
struct Foo1_Previews: PreviewProvider {
static var previews: some View {
Foo1()
}
}
So I call FetchRequest to get the data.
@FetchRequest(fetchRequest: FavoriteItem.getAllFavorites()) var isFavorite:FetchedResults<FavoriteItem>
When I print out isFavorite I can see all the data in my coredata model, but I'm not sure how I can run a contain that data.
This is what I thought would work
if isFavorite.contains(foo.name) {
print("it's already there nerd")
}
I get the error Cannot convert value of type 'String' to expected argument type 'FetchedResults<FavoriteItem>.Element' (aka 'FavoriteItem')
Do I need to do a foreach and check each item?
I have an app that is crashing only in iOS13. I don't see this issue on my iOS14 device or the simulator.
Here's the error I get in the console and I included the breakpoint error. The crash is happening on line 14.

New SwiftUI files are no longer rendering preview in canvas. I'm getting the error
MessageSendingError: Connection interrupted: send previewInstances message to agent.	
Existing views still render so far, but the default hello world isn't rendering.
I've restarted Xcode, my mac, clean and rebuilt the project and no change. I've tried add .environment(\.colorScheme, .dark) to the preview and that made no difference as well.
What am I missing?
I created a class and a function to make an API call and return some data. I get the data back in the console, but I'm not able to use the data and I think it's because I'm not completing the data correctly. The data being returned is surrounded by { } instead of [ ].
The function looks like this:
func getBusinessInfo(completion: @escaping ([Welcome]) -> ()) {
...
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
...
if let yelpbusinessinfo = data {
let decoder = JSONDecoder()
let yelpbusinessinfo = try? decoder.decode(Welcome.self, from: yelpbusinessinfo)
print(yelpbusinessinfo?.reviews[1].text)
completion(yelpbusinessinfo!)
}
At completion(yelpbusinessinfo!) I get the following error in the compiler and I'm assuming it has to do with how the data is being returned.
Cannot convert value of type 'Welcome' to expected argument type '[Welcome]'
Any help on what the proper format should be?
I'm trying to plot out map annotations from a JSON Response using MapKit. I've figured out some basic ways to plot out map points, but I"m not sure entirely what MapKit is expecting for map points. In my JSON response my struct is
// MARK: - Business
struct Business: Codable, Identifiable {
let id, alias, name: String
let coordinates: Center
}
struct Center: Codable {
let latitude, longitude: Double
}
Then my code looks like this, but I think I'm using CLLocationCoordinate2DMake incorrectly.
@State var yelpbusinessdataMap: WelcomeBusiness? = nil
var body: some View {
Map(coordinateRegion: $region,
interactionModes: MapInteractionModes.all,
showsUserLocation: true,
userTrackingMode: $userTrackingMode,
annotationItems: yelpbusinessdataMap?.businesses ?? []
)
{ places in
var new2DCoord = CLLocationCoordinate2DMake(places.coordinates.latitude, places.coordinates.longitude)
MapAnnotation(
coordinate:
new2DCoord,
anchorPoint: CGPoint(x: 0.5, y: 0.5)
){
Circle()
.stroke(Color.green)
.frame(width: 44, height: 44)
}
}
I tried using coordinate: places.coordinates,, but I get the following compiler error
Cannot convert value of type 'Center' to expected argument type 'CLLocationCoordinate2D'
I found in the latest update of iOS and xCode that onTapGesture isn't consistently registering onTap. Here's a stripped down version of the code I'm using that reproduces this issue. In this case onTap for safari is not working.
I don't reproduce this with iOS13 or if I'm using onLongPress
Has anyone else experienced this in the latest update?

I know about .onDelete modifier, but say I want to remove an item from Coredata using onTapGesture is that possible?
.onDelete { indexSet in
let deleteItem = self.isFavorite[indexSet.first!]
self.managedObjectContext.delete(deleteItem)
do {
try self.managedObjectContext.save()
}catch {
print(error)
}
}
I tried doing
.onTapGesture { indexSet in
let deleteItem = self.isFavorite[indexSet.first!]
self.managedObjectContext.delete(deleteItem)
do {
try self.managedObjectContext.save()
}catch {
print(error)
}
}
But that didn't go well.
I'm running into an issue where I'm trying to do two things
Uncheck an existing checkbox when another one is checked. Basically only allow for one state to be active.
When I have one boxed checked every box is showing checked when the pages appears as a sheet.
Here's a repro of what i'm working on.
struct Themes: View {
var body: some View {
List {
ForEach (themeData) { themedata in
ThemesView(themedata: themedata)
}
.padding()
}
}
}
struct ThemesView: View {
var themedata: themes
@State var themedCheck = UserDefaults.standard.bool(forKey: "ThemeChecked")
@State var themeColorUserSetting = UserDefaults.standard.string(forKey: "ThemeColor")
@State var themeColor = "card3"
var body: some View {
HStack(spacing: 16) {
Circle()
.fill(Color(themedata.color))
.frame(width: 25, height: 25, alignment: .center)
Text(themedata.name)
.font(.custom("ProximaNova-Regular", size: 18))
Text("\(self.themeColor)")
Spacer()
ZStack {
RoundedRectangle(cornerRadius: 7)
.stroke(style: StrokeStyle(lineWidth: 1.5))
.frame(width: 35, height: 35)
.foregroundColor(themedCheck ? Color("card2") : Color.gray.opacity(0.2))
RoundedRectangle(cornerRadius: 7)
.trim(from: 0, to: 1)
.fill(themedCheck ? Color("card2") : Color.gray.opacity(0.2))
.frame(width: 25, height: 25)
if themedCheck {
Image(systemName: "checkmark")
.foregroundColor(Color.white)
}
}
.onTapGesture{
if !self.themedCheck {
withAnimation(Animation.easeIn(duration: 0.5)) {
self.themedCheck.toggle()
UserDefaults.standard.set(self.themedCheck, forKey: "ThemeChecked")
UserDefaults.standard.set(self.themeColorUserSetting, forKey: "ThemeColor")
self.themeColor = themedata.color
}
} else {
withAnimation{
self.themedCheck.toggle()
UserDefaults.standard.set(self.themedCheck, forKey: "ThemeChecked")
self.themeColor = "card3"
}
}
}
}
}
}
struct themes: Identifiable {
var id = UUID()
var name: String
var color: String
}
let themeData = [
themes(name: "Default", color: "card3"),
themes(name: "Theme 1", color: "Theme1"),
themes(name: "Theme 2", color: "Theme2")
]
I have a userDefault using Appstorage and would like to have a function access that value to use in a switch. What would be the best approach to accomplish this?
I have two views where I'm trying to get View 2 to run the function in the Observable object and\or update an array so far I've not been able to get it to run or update the array. I'm still learning how to work with ObservableObjects. Thanks!
View1.swift:
@Published var arrayInt = [6, 6.5]
@Published var fooString = "Name"
func appendToArray() {
fooString = "Boom, updated!"
arrayInt.append(11)
}
}
struct GraphView: View {
@StateObject var graph = graphData()
var body: some View {
.... some data
}
}
View2.swift:
struct DetailView: View {
@StateObject var graph = graphData()
var body: some View {
....Some data
.onAppear{
graph.appendToArray()
graph.arrayInt.append(11)
}
}
}
Here's the model of the API that I'm using
// MARK: - Welcome
struct NOAAWeatherDecoder: Codable, Identifiable {
var id = UUID()
let type: String
let geometry: Geometry
let properties: Properties
enum CodingKeys: String, CodingKey {
case type, geometry, properties
}
}
// MARK: - Properties
struct Properties: Codable {
let updated: Date
let units, forecastGenerator: String
let generatedAt, updateTime: Date
let validTimes: String
let elevation: Elevation
let periods: [Period]
}
// MARK: - Elevation
struct Elevation: Codable {
let value: Double
let unitCode: String
}
// MARK: - Period
struct Period: Codable {
let number: Int
let name: String
let startTime, endTime: Date
let isDaytime: Bool
let temperature: Int
let temperatureUnit: TemperatureUnit
let temperatureTrend: JSONNull?
let windSpeed, windDirection: String
let icon: String
let shortForecast, detailedForecast: String
}
I am able to get upto periods, but nothing after that. Here's the part of the code where I'm running into the issue
ForEach(noaaWeatherData.weathernoaadata) { day in Text(day.properties.periods[0]) After this I'm not entirely sure. }
Thanks!
I'm racking my head here trying to figure out the best way to do this, but I have two arrays. One array is a range of dates and another is a return of data.
Here's the function that returns an array of dates
func numberOfDaysBetween(startDate: Date, raceDate: Date) -> [Date] {
let numberOfDays = Calendar.current.dateComponents([.day], from: startDate, to: raceDate).day!
let week = (-numberOfDays...0).compactMap {
Calendar.current.date(byAdding: .day, value: $0, to: raceDate)
}
return week
}
I'm trying to get the dates to align to the weekdays listed here. https://api.npoint.io/6a55ea69409d7f3d90b4.
Would a ZStack be appropriate here?
