Hello, my production app is experiencing some crashes according to app store analytics. I cannot seem to reproduce it.
According to Xcode Orginzer the app is crashing

After upgrading to iOS 17, Thread Performance Checker is complaining of priority inversion when converting a CVPixelBuffer to UIImage through a CIImage instance. It might be a false-positive or an issue?
- (UIImage *)imageForSampleBuffer:(CMSampleBufferRef)sampleBuffer andOrientation:(UIImageOrientation)orientation {
CVPixelBufferRef pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);
CIImage *ciImage = [CIImage imageWithCVPixelBuffer:pixelBuffer];
UIImage *uiImage = [UIImage imageWithCIImage:ciImage];
NSData *data = UIImageJPEGRepresentation(uiImage, 90);
}
The code snippet above, when running in a thread set to the default priority results in the message below:
Thread Performance Checker: Thread running at User-interactive quality-of-service class waiting on a lower QoS thread running at Default quality-of-service class. Investigate ways to avoid priority inversions

Dear all,
I have the following code in a view:
import SwiftUI
struct RosaView: View {
@State var rosa: [Rosa] = Rosa.testRosa()
@State private var apriNuovoGiocatore = false
@State var stagione: String = "2023/2024"
var rosaFiltrata: [Rosa] {
Rosa.testRosa().filter {
$0.stagione == stagione
}
}
@State private var selezioneGiocatore: Rosa.ID? = nil
@State private var ordine = [KeyPathComparator(\Rosa.ruoloGiocatore)]
var body: some View {
VStack(alignment: .leading) {
Text("Stagione: \(stagione)")
.fontWeight(/*@START_MENU_TOKEN@*/.bold/*@END_MENU_TOKEN@*/)
.font(.headline)
.foregroundColor(/*@START_MENU_TOKEN@*/.blue/*@END_MENU_TOKEN@*/)
.padding()
Table(rosaFiltrata, selection: $selezioneGiocatore, sortOrder: $ordine) {
TableColumn(Text("Nome").foregroundStyle(.blue), value: \.nomeGiocatore)
TableColumn(Text("Cognome").foregroundStyle(.blue), value: \.cognomeGiocatore)
TableColumn(Text("Ruolo").foregroundStyle(.blue), value: \.ruoloGiocatore)
TableColumn(Text("Data di nascita").foregroundStyle(.blue), value: \.nascitaGiocatore)
TableColumn(Text("Età").foregroundStyle(.blue)) {
Rosa in
Text("\(Rosa.etàGiocatore)")
}
}
}
.frame(width: 900, height: 400)
.toolbar {
Button {
apriNuovoGiocatore = true
} label: {
Image(systemName: "person.badge.plus")
.foregroundColor(/*@START_MENU_TOKEN@*/.blue/*@END_MENU_TOKEN@*/)
}
.sheet(isPresented: $apriNuovoGiocatore, content: {
nuovoGiocatore()
})
}
.navigationTitle("Rosa")
}
}
struct nuovoGiocatore: View {
@Environment(\.dismiss) var dismiss
@State var nomeNuovoGiocatore: String
@State var cognomeNuovoGiocatore: String
@State var nascitaNuovoGiocatore: String
@State var ruoloNuovoGiocatore: String
@State var etàNuovoGiocatore: Int
var body: some View {
NavigationStack {
Form {
TextField("Nome:", text: $nomeNuovoGiocatore)
TextField("Cognome:", text: $cognomeNuovoGiocatore)
}
.navigationTitle("Nuovo giocatore")
.toolbar {
Button("Cancel") {
dismiss()
}
Button("Aggiungi giocatore") {
let nuovoGiocatore = Rosa(stagione: "2023/2024", nomeGiocatore: nomeNuovoGiocatore, cognomeGiocatore: cognomeNuovoGiocatore, nascitaGiocatore: nascitaNuovoGiocatore, etàGiocatore: etàNuovoGiocatore, ruoloGiocatore: ruoloNuovoGiocatore)
Rosa.testRosa().append(nuovoGiocatore)
dismiss()
}
}
}
}
}
#Preview {
RosaView()
}
On this, I'm getting a strange error which is "Failed to produce diagnostic for expression; please submit a bug report (https://swift.org/contributing/#reporting-bugs)" in the "var body: some View" statement of the view "nuovoGiocatore".
How can I avoid it? Am I doing something wrong in the coding?
Thanks,
A.

I am running xctests from command line on XCode 15.2 on iOS 17.2 simulators. As per WWDC2021 video on Memory issues, I am passing `-enablePerformanceTestsDiagnostics Yes' in following xcodebuild command.
xcodebuild test -project project_name.xcodeproj -scheme test-scheme -destination 'platform=iOS Simulator,name=iPhone 15 Pro' -enablePerformanceTestsDiagnostics YES
Final logs before test results:
Tests-Runner(16873) MallocStackLogging: stack logs deleted from /private/tmp/stack-logs.16873.10148c000.Tests-Runner.M6gFw
.xcresults is generated but no memgraph file is attached along with it.
Consider the following program, memory-leak.c:
#include <stdlib.h>
void *p;
int main() {
p = malloc(7);
p = 0; // The memory is leaked here.
return 0;
}
If I compile this with clang memory-leak.c and test the output with the built-in MacOS memory leak detector leaks using leaks -quiet -atExit -- ./a.out, I get (partly) the following output:
1 leak for 16 total leaked bytes.
However, if I remove the 'leaking' line like so:
#include <stdlib.h>
void *p;
int main() {
p = malloc(7);
return 0;
}
Compiling this file and again running leaks now (partly) returns:
0 leaks for 0 total leaked bytes.
The man page for leaks shows that it is only un-reachable memory that is considered a leak. Is there a configuration to detect un-free'd reachablemalloc segments?

xCode requested that I send in a bug report.
Failed to produce diagnostic for expression, please submit a bug report. I can't manage to paste the image here, so I'll just state that the latest Xcode, 15.1 seems to produce spurious error messages on screen which usually manage to disappear over time.
I'll send this in to feedback with the sysdiagnose report.
It's a major pain.

Our CI pipeline produces .xcresult bundles that allow developers to diagnose failures by opening them in Xcode. If the test crashes, we used to be able to open the diagnostic folders and inspect the raw test logs. As of Xcode 15, that option is no longer available. I know the Diagnostic data is there because I can view it with Xcode 14. Am I just missing something in the Xcode 15 UI? Or has the capability to browse the Diagnostics actually been removed?

Hi folks!
My iOS app has the MetricKit integration, and I'm processing the reports on my server. While looking at some MXCrashDiagnostic reports, I saw certain reports that has threadAttributed property as true, but callStackRootFrames is just an empty array. So the report looks like the following example
"callStacks" : [
{
"threadAttributed" : true,
"callStackRootFrames" : [ ]
},
// ...
// other callstacks where threadAttributed is false
// but callStackRootFrames is not empty
]
Looking at the documentation I can see threadAttributed is used to determine if the crash/exception occurred in this crash. So I can't understand how callStackRootFrames can be empty when threadAttributed is true.
Is this a bug or an expected behavior?
Also, is there a case where the crash/exception report does not have any callstack with threadAttributed as true? From the definition, it feels like there should always be exactly one attributed thread on each crash report.
Thanks for the help!
Hello I have a problem with xCode, I have this error : Cannot find « string » in scope.
