I'm trying to create a USDZ object with the tutorial from Apple
Creating 3D Objects from Photographs. I'm using the new PhotogrammetrySession within this sample project: Photogrammetry Command-Line App.
That's the code:
let inputFolderUrl = URL(fileURLWithPath: "/tmp/MyInputImages/")
let url = URL(fileURLWithPath: "MyObject.usdz")
var request = PhotogrammetrySession.Request.modelFile(url: url,
detail: .full)
guard let session = try PhotogrammetrySession(input: inputFolderUrl) else {
return
}
I'm getting the following error:

I'm using an M1 iMac with macOS Monterey 12.0 Beta (21A5248p) and Xcode 13.0 beta (13A5154h).
tl;dr: Try another set of images, probably there is something wrong with your set of images.
I've had it work successfully except in one instance, and I received the same error that you are getting. I think for some reason it didn't like the set of photos I took for that particular object. You could try taking just a few photos of another simple object and try again and see if that is the problem with your first run.

------LE: We ended up removing the encryption of the database because with realm team suggestions it got worse - all we could do was to remove the database and loose all stored info. Now we encrypt in keychain only the fields we need.------
I have an app released in store and after updating their iOS version to 14+, users started to complain about info not being populated from database. Not all users with iOS 14+ have this issue, it appears randomly on some devices.
The issue goes away for awhile if they reinstall the app or after they update it to another version, but after using it for a few minutes it happens again.
My database uses encryption as documented here.
The store version of my app uses Realm 5.4.8, but I tested their last version (10.0.0) and the issue is still present.
I checked this issue but it's not the case for me, I don't have a shared app group container or a share extension.
Here's how the initialisation of realm looks like:
override init() {
super.init()
do {
guard let config = getMigrationAndEncryptionConfiguration() else {
realmConfigured = try Realm()
return
}
realmConfigured = try Realm(configuration: config)
} catch let error as NSError {
// this is where I got the error:
//"Encrypted interprocess sharing is currently unsupported.DB has been opened by pid: 4848. Current pid is 5806."
}
}
func getMigrationAndEncryptionConfiguration() -> Realm.Configuration? {
let currentSchemaVersion: UInt64 = 19
if Keychain.getData(for: .realmEncryptionKey) == nil {
var key = Data(count: 64)
_ = key.withUnsafeMutableBytes { bytes in
SecRandomCopyBytes(kSecRandomDefault, 64, bytes)
}
Keychain.save(data: key, for: .realmEncryptionKey)
}
guard let key = Keychain.getData(for: .realmEncryptionKey) else {
return nil
}
let fileUrl = Realm.Configuration().fileURL!.deletingLastPathComponent()
.appendingPathComponent("Explorer.realm")
var config = Realm.Configuration(fileURL: fileUrl,
encryptionKey: key,
schemaVersion: currentSchemaVersion, migrationBlock: { (migration, oldVersion) in
if oldVersion != currentSchemaVersion {
print("we need migration!")
}
})
return config
}
I had another question opened for the same issue on SO, but it was closed because I didn't have enough details. After another release of my app with more logs, I could find the error that appears at initialisation of realm:
"Encrypted interprocess sharing is currently unsupported.DB has been opened by pid: 4848. Current pid is 5806. "
This appears after the app goes to background, it gets terminated (crash or closed by the system/user) and when the users opens it again, realm fails to init.
I read all about encrypted realm not being supported in app groups or in a share extension, but I didn't implement any of that in my app, is there any other reason why this error happens?
I also removed Firebase Performance from my app because I read that this module could generate issues on realm database, but it didn't help.
I opened an issue on realm github page, but I got no answer yet.
Does anyone have any idea how to fix this or why is this happening?
Thank you.
I am working out how to use the Contacts framework, however some fairly simple code to create a contact is failing with an unexpected result. This is my code:
let Store = CNContactStore()
Store.requestAccess(for: .contacts, completionHandler:{ success, error in
if success {
let Contact = CNMutableContact()
Contact.givenName = "Dave"
Contact.familyName = "Nottage"
let SaveRequest = CNSaveRequest()
SaveRequest.add(Contact, toContainerWithIdentifier: nil)
do {
try Store.execute(SaveRequest)
print("Success")
}
catch let error as NSError {
print(error.localizedDescription)
}
} else {
print("No access")
}
})
..and this is the result:
2019-02-22 10:30:56.050344+1030 ContactsTest[30329:25254955] [default] Unable to load Info.plist exceptions (eGPUOverrides)

The operation couldn’t be completed. (Foundation._GenericObjCError error 0.)
Any ideas on what might be causing this?
Edit: Note also that this is being compiled for macOS 10.14 SDK, and is running on macOS 10.14.3
The answer is to check the Contacts checkbox of App Data in the App Sandbox section in Capabilities and turn on the switch for App Sandbox.
Make sure you added key NSContactsUsageDescription in Info.plist.
Please refer to link.
Important
An iOS app linked on or after iOS 10.0 must include in its Info.plist
file the usage description keys for the types of data it needs to
access or it will crash. To access Contacts data specifically, it must
include NSContactsUsageDescription.
Initial use and testing of the framework. The examples provided and most of the searches from across the internet are using "local" or downloaded CSV files to the device, with (path:).
I would like to pass various remote URLs but there are not many examples, using (url: URL).
So far, I am simply in viewDidLoad() following the same code as provided with the sample playground file, and trying to output to the console.
I have tried to run this in a simulator for the iPhone 8 device. Running Xcode 10.1.
From the documentation, there is an ".onFail" handler, which gets invoked on the sourceURL's I have provided, but I do not know what error objects exist to do any further troubleshooting.
let sourceURL = URL(string: "https://files.datapress.com/leeds/dataset/leeds-city-council-dataset-register/Dataset%20register.csv")
guard let sourceURL2 = URL(string: "https://minio.l3.ckan.io/ckan/ni/resources/2477b63a-b1c4-45cc-a5ee-8e33e5b20b5b/supplies-and-services-contracts---2014.2015-yr.csv?AWSAccessKeyId=aspjTDZu90BQVi&Expires=1546982840&Signature=dLDVWMu%2Fp4RiePIRhntCX6WFMpw%3D") else {
fatalError("URL string error")
}
let importer = CSVImporter<[String]>(url: sourceURL)
importer?.startImportingRecords { $0 }.onFail {
print("fail")
}.onFinish({ importedRecords in
print(importedRecords.count)
})
I have two projects: an iOS project using iOS Charts that plots the data without any problems and a Mac companion app that fails when assinging the data to the lineChartView.data object. I also get a warning:
'warning: could not execute support code to read Objective-C class data in the process. This may reduce the quality of type information available.'
Here is my code:
let values = (0..<count).map { (i) -> ChartDataEntry in
let value = recordingpoints[i]
return ChartDataEntry(x:Double(i), y: value)
}
let data = LineChartData()
let dataset = LineChartDataSet(values: values, label: "Glucose Trends")
data.addDataSet(dataset)
self.lineChartView.data = data
I cannot find where the error is generated. Here is a screenshot of the error:

As Parse crash report is depreciating, we are moving to Google Analytics.
I follow the guide to and receive view tracking and exception reports successfully.
here is how I setup the GA
// Configure tracker from GoogleService-Info.plist.
var configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
// Optional: configure GAI options.
let gai = GAI.sharedInstance()
gai.trackerWithTrackingId("UA-XXXXXX-1")
gai.trackUncaughtExceptions = true // report uncaught exceptions
gai.dispatchInterval = 1
gai.defaultTracker.allowIDFACollection = true
#if DEBUG
gai.logger.logLevel = GAILogLevel.Verbose // remove before app release
#endif
And I tried to make a crash by (in AppDelegate.swift didFinishLaunchingWithOptions ):
delay(20.0) { () -> () in
let _ = [String]()[10];
}
And I can't get any crash report from GA dashboard.
I've tried to move this line to an IBAction, but failed.
My testing steps:
debug on device ->(20s)-> crash
debug on device 2nd time ->(20s)-> crash
run the app without debugging ->(20s)-> crash
run the app without debugging ->(20s)-> crash
It turns out that Google Analytics only supports reporting of uncaught Objective-C exceptions. It does not report Swift throws. The following creates a Swift throw (and is not reported by GA):
let crashArray:Array = [0]
crashArray[1]
The following does create an Objective-C exception and is reported by GA:
let array = NSArray()
let _ = array.objectAtIndex(99)
Some useful information here...
How should I use NSSetUncaughtExceptionHandler in Swift
We can force an Objective-C exception from within Swift by using the following command (i.e. from within a catch).
let error = NSError(domain: "Some error.", code: 0, userInfo: nil)
NSException.raise("Exception", format:"Error: %#", arguments:getVaList([error ?? "nil"]))
There is not a way I can find to automatically capture all throws and relay them as an Objective-C exception.
