Reply to IOS 14 HEATING MY IPHONE
SOLVED (at least for me)! Over several weeks after upgrading from 13.7 to 14.4.x I tried turning off MANY Settings and offloading all 3rd-party apps -- to no avail. Still sluggish, overheating, and fast battery drain anytime screen was on. An apple-support tech mgr suggested doing a full Settings&Content Reset to confirm if a hardware problem. And phone worked fine as as empty new phone... so was definately confused software. So I re-did a full reset and restored from iCloud backup and it SOLVED this problem on my iPhoneSE(1st gen). So do THIS: do a full icloud-backup (pay 99 cents for 1 month increased storage) (Settings/General/RESET ALL CONTENT AND SETTINGS (As it reboots it will reset/reinstall to 14.4.2) Follow phone setup steps and login into your apple ID and restore from the iCloud backup. After doing those my SE was back to normal!! :)

Help Me: SpotlightNetHelper Hijacks System is this a Virus?
To Whom It May Concern:I apparently have a self propagating virus that was introduced to my network by purchase of a used Mac computer from Amazon.com on approximately December 24, 2015. That is when I first started noticing erratic behavior on my machines. I have clean formatted and reinstalled OS from computers on an isolated network that was not infected. As soon as I connect the newly reinstalled OS iMacs to the infected network they become reinfected on first boot. I've spent something like 40 labor hours on this so far and I can't afford anymore resource allocation to this issue until there are some steps to cure the system.This activity on my computer appears to be a nasty virus. From what I can tell, it tries injecting itself in every executable it can locate. It trys to obtain the icloud login credentials, it attempts to obtain administrator credentials, and on one computer it appears to have secured and stolen my credentials to completely hijack the computer. Once it hijacks the computer it deletes

Reply to macOS Big Sur Not Enough Free Space
I have a 128 Gig Mac Mini. I was ready to give up on Big Sur after seeing how much free space I needed to free up. Here's how I made the space available. Copy the Big Sur installer to a removable drive and remove it from your startup drive. Run the installer to see how much more space you need. Follow Apple instructions to offload Music and Photos libraries to a removable drive. If you are a developer, you probably have a huge Developer folder in your user library. Copy it to a removable drive and remove it temporarily. These steps worked for me and I was able to upgrade to Big Sur. The installer seemed to do a very good job of cleaning up OS X folders because I had 50 GB available after the install. Plenty of space to copy the Developer folder back to the startup drive.

hi, I don't hope setting your network to less secure is the answer.

What does this error log message mean?
When I'm debugging my VPN tunnel provider application on the iPhone device I found some error logs in the console: udp_validate_cksum_internal [C8.1:1] udp incorrect IPv4-UDP non-offload checksum 0xeaff ulen 1502 It only appears when I'm tuning the MTU to a bigger value for the NEPacketTunnelNetworkSettings. What does this message mean? Does it mean the inbound udp packet has a bad checksum and will it be dropped by iOS?

Reply to What does this error log message mean?
And another found is that on the home Wifi network(which has PPPoE router provided by carrier) with an iOS 14 iPhone the message will be like udp_validate_cksum_internal * udp incorrect IPv4-UDP non-offload checksum * ulen 1506 And the pppoe header length is 6. Compared with previous network with Vlan the error message showed ulen is 1502. I believe there most probably a bug exists somewhere in iOS 14 kernel or in network extension. Since I didn't found such issue under the same condition on iOS 12, this issue may only exists in iOS 14. The reproduce condition is with NEPacketTunnelProvider set the MTU of the UTUN to be a value bigger or equal than 1480(Theoretically we should be able to set this value to a very big size like 65535 and without any problem) or overhead size to be 0, and run it on an iOS 14 iPhone, on a Wifi network which has a Vlan setting or PPPoE, on inbound packets there will be such problem.

Reply to System Storage Full
It is November 2020, and my Iphone 6s has just been reset to factory settings because of this. So, no, we cannot assume that Apple has fixed anything in the new updates, nor will they. I've been experience a slow decay of storage space on my, already too compact, 16gb phone. 6gb taken by the storage, so this phone is actually a 9gb phone, sold as a 16gb phone. Over the past 2 months my phone went from the occasional offloading of an app, to having almost 0gb of space. I was so confused, as apple does little to nothing to explain to their customers how to handle the defuncts in the system. I started using icloud, uploading everything possible to it. It did absolutely nothing, nothing at all. You have to go through absurd hoops and hurdles to export your iphone photo library into your computer and separate them from icloud, so that they won't disappear when you delete them off your phone. Learned that lesson before, should out to apple iCloud for losing 500-1000 of my pictures to iCloud in 2018. So, ev

Reply to App quits right after it is launched from home screen
Similar here, but even worse! We are having more and more users who have the same issue after any kind of updates (os updates as well as app updates). The app shows the launch screen and then quits, no even calling didFinishLaunching. In same cases, the workaround is to send the app to icloud (offload) and then restart it, restoring all data from the cloud. Unfortunately, this worked fine in iOS 13 but does not always work in iOS 14.0. Currently, the only way to make the app work again is to delete and reinstall it, letting the user lose all of the data assign to the app. THIS IS A DESASTER for most of our users. We URGENTLY need a solution.

same with me, I installed iOS 14 beta on my iPhone 11 Pro Max and after that it just started kicking me out of apps and randomly disconnecting bluetooth. My AirPods 2 and the Pros. I then downloaded iOS 14 and now 14.0.1 and offloaded the beta. But nothing helped. It’s really getting frustrating, especially when your on a phone call. I hope this gets resolved asap.

Reply to Update SwiftUI View on NSManagedObject edit
hi, one correction to my last reply: point number (3) wasn't quite right (i had it backwards; sorry, it was the last thing i wrote before heading off to bed). it should have been: (3) instead, if you write something like ExerciceHistoryRow(name: exerciceHistory.name!) and you use var name: String for the View, that will be updated properly. be sure to NOT define this variable using @State, because that gives ownership of the View to SwiftUI. and in general, you'll obviously want to pass along more than just date for a single field in the object ... my conclusions about this whole display not updating situation, especially with Core Data objects (one i've been struggling with for some time): passing a reference to an object to a RowView works fine if it is an @ObservedObject -- and if the RowView makes any changes to the object, you'll know about it. however, deleting that object will crash if the RowView is still held onto by SwiftUI when the deletion occurs.

Reply to Passing ObservableObject to View within NavigationView and editing it
hi, i'll offer three suggestions. there's no need (or there may be, but not in this example) for User to be a class. make it a struct and kill the ObservableObject protocol. struct User: Identifiable { let id = UUID() var name: String init(name: String) { self.name = name } } treat the Users object as a viewModel, and when a change is made to a user's name, provide a method for the Users object to do that. class Users: ObservableObject { @Published var users: [User] init() { self.users = [ User(name: John Doe), User(name: Jane Doe) ] } func updateUsername(for user: User, to newName: String) { if let index = users.firstIndex(where: { $0.id == user.id }) { users[index].name = newName } } } and treat the UserDetailView to not be a live edit, but one where you have parameters users and user coming in; you offload the name you want to edit when the view comes on screen; and when you save the edit, ask the Users object to make that change for you. something like this (with the Save button now also dismissi

Reply to Data flow and managed objects in SwiftUI
Okay I've cracked it open and tried out the method of passing in the data rather than the object itself by offloading to a struct. That definitely solves the issue, optically, but I need to refactor editing of deleting the item from the modal. I'm sure i'll figure it out tonight. If I get stuck again or have further questions I'll be back! Regardless, thanks DMG for the help and great ShoppingList project as a resource!

Reply to How might I reset "maximum number of apps for free development profiles has been reached"?
To clarify, this is a bug: Any iCloud offloaded apps installed on the phone are counted as developer installed apps until reinstalled or deleted. You can confirm this in the console when looking at the MIFreeProfileValidatedAppTracker error message. Once these have been either reinstalled or deleted, then the list of offending apps will disappear.
