Hi,
I tried to make a new branch of my project and upon doing so, all of my old files disappeared. They are no longer in my folder directory or available in Xcode. Please let me know if there is any way to recover these files. I don't see the files in my trash either.

I need to render a PDF and then make it downloadable to the mobile device. I can generate the PDF but I'm unsure how to configure the download aspect. I have the following code:
let renderer = UIGraphicsPDFRenderer(bounds: CGRect(x: 0, y: 0, width: 612, height: 792))
let pdf = renderer.pdfData { (context) in
context.beginPage()
let text = "Test" as NSString
text.draw(in: CGRect(x: 0, y: 0, width: 100, height: 25))
I have the following code for generating a one page PDF:
@MainActor func render() -> URL {
let renderer = ImageRenderer(content: pdfView))
let url = URL.documentsDirectory.appending(path: "output.pdf")
renderer.render { size, context in
var document = CGRect(x: 0, y: 0, width: 2550, height: 3300)
guard let pdf = CGContext(url as CFURL, mediaBox: &document, nil) else {
return
}
pdf.beginPDFPage(nil)
context(pdf)
pdf.endPDFPage()
pdf.closePDF()
}
return url
}
I'm trying to write code to create a multi-page PDF if there is multiple ImageRenderers. I tried something shown below but I'm not sure how to properly implement.
@MainActor func render() -> URL {
let renderer = ImageRenderer(content: pdfView)
let url = URL.documentsDirectory.appending(path: "output.pdf")
for image in renderer {
image.render { size, context in
var page = generatePage(image: image)
}
}
return url
}
func generatePage(image: ImageRenderer<<#Content: View#>>) -> CGContext {
var view = CGRect(x: 0, y: 0, width: 2550, height: 3300)
guard let pdf = CGContext(url as CFURL, mediaBox: &view, nil) else {
return
}
pdf.beginPDFPage(nil)
context(pdf)
pdf.endPDFPage()
pdf.closePDF()
return pdf
}
Any guidance would be greatly appreciated. Thank you.
Hi, I have a couple questions about background app refresh. First, is the function RefreshAppContentsOperation() where to implement code that needs to be run in the background? Second, despite importing BackgroundTasks, I am getting the error "cannot find operationQueue in scope". What can I do to resolve that? Thank you.
func scheduleAppRefresh() {
let request = BGAppRefreshTaskRequest(identifier: "peaceofmindmentalhealth.RoutineRefresh")
// Fetch no earlier than 15 minutes from now.
request.earliestBeginDate = Date(timeIntervalSinceNow: 15 * 60)
do {
try BGTaskScheduler.shared.submit(request)
} catch {
print("Could not schedule app refresh: \(error)")
}
}
func handleAppRefresh(task: BGAppRefreshTask) {
// Schedule a new refresh task.
scheduleAppRefresh()
// Create an operation that performs the main part of the background task.
let operation = RefreshAppContentsOperation()
// Provide the background task with an expiration handler that cancels the operation.
task.expirationHandler = {
operation.cancel()
}
// Inform the system that the background task is complete
// when the operation completes.
operation.completionBlock = {
task.setTaskCompleted(success: !operation.isCancelled)
}
// Start the operation.
operationQueue.addOperation(operation)
}
func RefreshAppContentsOperation() -> Operation {
}
I was wondering if errors are common for the code below for saving SwiftData data and what would be the best way to handle them (popup, closing the app)?
do {
try modelContext.save()
} catch {
print("error")
}
With the code below, JSON data is parsed and is stored in the variable data in the .onAppear function, however an empty set of data is passed to the Content view. How can that be fixed so that the JSON data passes to the DataView?
struct ContentView: View {
@State var data: [Data]
@State var index: Int = 0
var body: some View {
VStack {
DataView(data: data[index])
}
.onAppear {
let filePath = Bundle.main.path(forResource: "data", ofType: "json")
let url = URL(fileURLWithPath: filePath!)
data = getData(url: url)
}
}
func getData(url: URL) -> [Data] {
do {
let data = try Data(contentsOf: url)
let jsonDecoded = try JSONDecoder().decode([Data].self, from: data)
return jsonDecoded
} catch let error as NSError {
print("Fail: \(error.localizedDescription)")
} catch {
print("Fail: \(error)")
}
return []
}
}
I was wondering if there was a way to submit an app for review before completing the terms of service and privacy policy in case the app does not get approved.
