How would I be able to make an if statement that could check the current time in the local time zone and see if it is between two set times.For example, I want the if statment to be like If the current time is between 13:00 and 15:00, run the code in the if statment.How can I do this?

I am facing an error regarding crypto kit in Touch ID device. I am using secure enclave for storing login credentials using Touch ID.During Touch ID setup and storing the data on secure enclave are working fine but I am getting below error intermittently on iOS 13 while retrieving the data.Error Domain=CryptoTokenKit Code=-2 Failed to get externalisedContext from LAContext.I can't find any answer online. Thanks in advance.P.S.- I am getting this issue only on touch ID (working fine for face ID) devices and on iOS 13.

Hi, I'm making this post partly as a bug report, and partly to help others that run into what I just did using SwiftData (and probably happens in CoreData). I have a model I just added in my app that looks kinda like this: @Model final class Reference { // represents a reference to an external web source var project: Project } and I tried adding a relationship to a parent model: @Model final class Project { @Relationship(deleteRule: .cascade, inverse: Reference.project) var references = [Reference]() } I then started getting a crash with EXC_BAD_ACCESS(code=2 on Previews, and running it in simulator/device revealed the crash to be happening on the ModelContainer initialization at the App startup: After hours of searching for a solution, I saw some mention of similar unexplained crashes occurring due to some property names that CoreData doesn't like, but are not documented as such. So I changed the references variable in Project to projectReferences on a hunch (references is a core programmin

I am trying to rewrite the following code into Swift 3, can anyone Help? self.queryDidUpdateObserver = NSNotificationCenter .defaultCenter() .addObserverForName(NSMetadataQueryDidUpdateNotification, object: metadataQuery, queue: NSOperationQueue.mainQueue()) { (notification) in self.queryUpdated() } self.queryDidFinishGatheringObserver = NSNotificationCenter .defaultCenter() .addObserverForName(NSMetadataQueryDidFinishGatheringNotification, object: metadataQuery, queue: NSOperationQueue.mainQueue()) { (notification) in self.queryUpdated() }

I am having trouble getting the puzzle to reload -- the gems and switches are in pixel form and never fully load into the maze. I've tried resetting the page and force closing the app. I can't get my code correct on the first try, so I'm out of luck. Using an iPad Air 2.

I'm currently writing a code to achieve the RSA encryption via C++, and I stumbled across this error message when I was running it. The first part of my code is to generate random prime numbers based on the digit from the input for the encryption. For example, if you enter 6 then the code will generate two prime numbers, M and m, between 100000 to 999999. The fin variable equals (M-1)*(m-1), and based on fin I will create an int array the size of [fin+1] in the Random e section. However, if I enter a number greater than 3 ( which means fin will go beyond 6 digits) the crash will occur and the error message will show. I can't seem to find the problem anywhere, and if my input is no greater than 3 then the code will work exactly as I wanted it to. Is there something I missed? Thank you very much.

Hi,I am using SecKeyCreateSignature to sign the data. It works for most users but for some iOS 13 users we are getting following error:Error Domain=CryptoTokenKit Code=-2 Failed to get externalizedContext from LAContext UserInfo={NSLocalizedDescription=Failed to get externalizedContext from LAContext}The error is only happening on iOS 13 devices and happens intermittently. I have copied the relevant code below:-(NSData*) signData:(NSString*) textData withAuthenticator:(SANDKSecurityDeviceAuthenticator) auth andUID:(NSString*) userID error:(NSInteger*) errorCode { Authenticator *authenticator = [AuthenticatorManager getAuthenticator:auth]; // Get private key selected for signing NSString *alias = [NSString stringWithFormat:@%@%@, userID,authenticator.type]; SecKeyRef privateKey = (SecKeyRef)[authenticator getPrivateKeyRef:alias]; // Generate digest NSData* dataToSign = [textData dataUsingEncoding:NSUTF8StringEncoding]; NSData* hashedDataToSign = [HashUtils hasData:dataToSign withAlgo

I'm a newbie to IOS but coming along. I have a single view swift 2 project that I would like to use to connect to an Arduino and send data back and forth.The examples I find on the internet are mostly objective c and too difficult for me to convert. And frankly I think with swift 2 they are a bit out of date.I found one app that sends the changing values of a slider to an Arduino BLE Shield. I have changed the UUID to match the UUID of the Arduino shield but I don't see where they connect as I walk through the code with breakpoints.I am looking for someone who can help me one on one, to get over the hump, with this simple app.

I have 1 UIViewController with a type of CustomTableView and 1 UITableViewController with a type of usual UITableView. Both conform to NSFetchedResultsControllerDelegate and implemented its delegate methods with the repeated code. For now it's in extensions. Is it possible to move that code out to a separate swift file? I tried to move it to separate file with class NSFetchedResultsView, but when I copy that delegate methods to the new file, it doesn't know anything about tableView inside it's methods... How can I separate that methods properly? Delegate methods I want to separate: func controllerWillChangeContent(_ controller: NSFetchedResultsController) { tableView.beginUpdates() } func controllerDidChangeContent(_ controller: NSFetchedResultsController) { tableView.endUpdates() } func controller(_ controller: NSFetchedResultsController, didChange anObject: Any, at indexPath: IndexPath?, for type: NSFetchedResultsChangeType, newIndexPath: IndexPath?) { switch type { case .update: if let in

Hello everyone,Greeting for the day...!!!!I have two different projects, let's say PROJECT 1 and PROJECT 2. In both projects some files (code and design) are common. Now I want to create PROJECT COMMON that should contain common files and make it separate application. And also want to create all three targets (PROJECT 1, PROJECT 2 and PROJECT COMMON) in single application.How can it possible, please help me if anyone have an idea.Thanks.

Hi folks the solution I used is outside the box and is a lot of fun. The expert appears, grabs the gem, disappears, reappears on next square facing different compass point and so on. No walking or working and still successful!See outcome at: https://youtu.be/Rids5hiVr4UThis is a big deal to me as a newbie.Oz

I have tried to use Screen Time API. The problem is that I can't get access to FamilyControl framework on parent's device.
