Hi there,
I am currently programming an app for certain medication usage for paramedics in my region. For that, I made a List inside a NavigationStack with NavigationLinks to further Swift files, each one for one drug. The problem is, that when I add more than 16 NavigationLinks to the NavigationStack, the app stops working and crashes. Is it too much code or do I have to do anything else? I am very new to programming in general so I would love to hear from you!
Greetings

Hey there,
I am quite new to SwiftUI and currently trying to implement a pdf file into my app. When run the app on my iPhone the pdf file opens without any problems but I always get this Error:
Unable to open mach-O at path: default.metallib Error:2
I do not actually understand the code completely I found on multiple websites, but what am I doing wrong? I attached my used code.
Thanks for your help!

Hey there,
I am quite new to SwiftUI and I am currently programming an app with several NavigationLinks. The app should be in German in the end, but I have no idea how I can translate the back buttons into other languages. Can someone help?
Thank you so much!

Hi there,
I am still quite new to Swift and have following problem: Many animations in my app have bugs, like you can see in the attached images. I cannot attach a video so I attached images from the video. Here is my description: When I click on a NavigationLink, the title of the following page appears after the animation and the whole content of the page moves up. What can I do against this?
This is my code from the first page:
struct Medikamente: View {
var body: some View {
NavigationStack {
List {
Group {
NavigationLink(destination: Acetylsalicylsaeure()){
Image("AcetylsalicylsaeureMediLabel")
.resizable()
.frame(width:60, height: 30)
Text("Acetylsalicylsäure")
}
NavigationLink(destination: Amiodaron()){
Image("AmiodaronMediLabel")
.resizable()
.frame(width:60, height: 30)
Text("Amiodaron")
}
NavigationLink(destination: Atropin()){
Image("AtropinMediLabel")
.resizable()
.frame(width:60, height: 30)
Text("Atropin")
}
NavigationLink(destination: Butylscopolamin()){
Image("ButylscopolaminMediLabel")
.resizable()
.frame(width:60, height: 30)
Text("Butylscopolamin")
}
// More medication
}
}
.navigationTitle("Medikamente")
.navigationBarTitleDisplayMode(.automatic)
}
}
}
#Preview {
Medikamente()
}
And this is the code from the second page.
struct Acetylsalicylsaeure: View {
var body: some View {
NavigationStack {
List {
Section {
Image("AcetylsalicylsaeureMediLabel")
.resizable()
.scaledToFit()
}
NavigationLink(destination: List {
Section {
Text("**500 mg Trockensubstanz** + 5ml Lösungsmittel")
Text("diverse orale Darreichungsformen")
} header: {
Text("**Allgemeine Informationen** \nKonzentration")
}
Section {
Text("Thrombozytenaggregationshemmer")
} header: {
Text("Arzneimittelgruppe")
}
.navigationTitle("Acetylsalicylsäure")
.navigationBarTitleDisplayMode(.inline)
}) {
Text("Allgemeine Informationen")
}
// More NavigationLinks...
NavigationLink(destination: List {
Section {
Text("Im Rettungsdienst nicht möglich")
} header: {
Text("**Erfolgsprüfung**")
}
.navigationTitle("Acetylsalicylsäure")
.navigationBarTitleDisplayMode(.inline)
}) {
Text("Erfolgsprüfung")
}
NavigationLink(destination: List {
Section {
Text("Lt. BPR „Akutes Coronarsyndrom“, Heparin 5.000 I.E. i.v.")
} header: {
Text("**Folgemaßnahmen**")
}
.navigationTitle("Acetylsalicylsäure")
.navigationBarTitleDisplayMode(.inline)

Text("Folgemaßnahmen")
}
.navigationTitle("Acetylsalicylsäure")
.navigationBarTitleDisplayMode(.inline)
}
}
}
}

Hi there,
I am currently developing an app for iPhone and iPad. I made a sidebar with various items which are linked to other pages via NavigationLink.

Hi there,
I am currently developing an app. I would like to make NavigationLinks from certain words inside an implemented .pdf-file to other Swift view files. Is there a possibility to do this?
Here is my code:
import PDFKit
struct BasismassnahmenPDF: UIViewRepresentable {
let pdfDocument: PDFDocument
init(showing pdfDoc: PDFDocument) {
self.pdfDocument = pdfDoc
}
func makeUIView(context: Context) -> PDFView {
let pdfView = PDFView()
pdfView.document = pdfDocument
pdfView.autoScales = true
return pdfView
}
func updateUIView(_ pdfView: PDFView, context: Context) {
pdfView.document = pdfDocument
pdfView.minScaleFactor = 0.6
pdfView.scaleFactor = pdfView.scaleFactorForSizeToFit
}
}
struct Basismassnahmen: View {
let pdfDoc: PDFDocument
init() {
let url = Bundle.main.url(forResource: "Basismassnahmen", withExtension: "pdf")!
pdfDoc = PDFDocument(url: url)!
}
var body: some View {
BasismassnahmenPDF(showing: pdfDoc)
}
}
#Preview {
Basismassnahmen()
}

Hi there,
I am currently developing an app with a tab view. Unfortunately some the symbols I use only work for iOS 17. I would like to change a symbol but only for iOS 16. Is this possible?
Thank you for your help!

Hi there,
I am still quite new to Swift. Is there a easy way to search a list with navigation links to other swift pages?
Thank you so much for your help!

Hi there,
I am still quite new to Swift and want to combine a few views into one single view. But the problem is, that if I do it like in the following code, there are windows for each view. Is there a chance to code it that it is one coherent view where I can scroll through?
Thank you for your help!

Hi there,
I would like to implement a search bar into my existing list, filled with NavigationLinks. Is there a possibility to mark all my existing NavigationLinks with variables that I can show them in my search list?

var body: some View {
NavigationView {
List {

Hi there,
I am quite new to SwiftUI and got this problem: I want to implement TipKit in my app but as soon as I put DisplayFrequency and datastoreLocation into my code, I get this error message:
I know that I somehow could look it up in the documentation but unfortunately I am still so new, that I don't understand it. Could someone help?

Hi there,
I am still quite new to SwiftUI and made a .searchable list as you can see in my code below. When I search, all list headers are displayed, even if there aren't any results in that list. How can I fix that?
Thank you for your help!

Hi there,
I have got a question but I don't know if this is the right place. I am using an M1 Mac mini and have installed Fedora Asahi Remix for certain developing Tasks next to MacOS. How is the fan speed controlled? Does Fedora turn on the fan when the CPU gets warm or does the hardware firmware set the fan speed?
Thank you for your answers!
