I'm programmatically adding a contact with an image with the intention the image should display in full screen size when a caller matching the number of the contact calls (as opposed to the image appearing as a tiny round icon next to the caller name). I'm creating an image of the same size and scale factor as the iPhone, and so far its working out ok - I have about 15 different phones, of various dimensions and scale factors, ranging from an old iPhone mini up to the most recent iPhone Pro Max, and on all of these it works as intended. But there's an exception, an iPhone 12 Pro (which has dimensions 390 * 844 and scale factor 3), on this phone when there is a call the contact image appears as a tiny icon. Why. Why is this phone different? How can I know what size image should be added to a contact to appear at full size in the call screen when every phone has different dimensions and they are not behaving the same? Additional question - the iPhone applies some cropping and expansion to whatever image gets added, is it possible to know what's being done to the image in order to make it display perfectly? (i.e. if the image contains some text, the fact the OS crops away some of the edge of the image, then expands what's left to fill the screen dimensions results in some pixelation)

This takes 2 minutes to recreate: Create a new project in XCode Run pod init to create a pod file Add some pod to the pod file, I tried with MMWormhole or PhoneNumberKit or Realm Run pod install The app can be built however an archive cannot, it generates an error: rsync error: some files could not be transferred (code 23) at /AppleInternal/Library/BuildRoots/97f6331a-ba75-11ed-a4bc-863efbbaf80d/Library/Caches/com.apple.xbs/Sources/rsync/rsync/main.c(996) [sender=2.6.9] Switch to Xcode 14.2 however and the archive can be built

An app can legally link into its own section of the Settings app, and if it uses CallKit, it can link into the Call Blocking & Identification section. Linking anywhere else into Settings is making use of private URL schemes and is supposed to not be permitted and the app rejected during submission. However the Robokiller app deep links into the Settings app with the page scrolled down to where the Phone section is. How are they doing that? Is there some new API that permits the app to link to there? Or are they making illegal use of private URIs and have been getting away with getting past App Store review for years?

I intentionally deleted iOS development/distribution related certificates from my keychain (Login, Local Items, System, System Roots). Then built my app in Xcode. Automatically manage signing is turned on and Xcode created/installed an Apple Development certificate to my keychain). But if I create an archive, I am able to successfully create a development distribution, an ad-hoc distribution, and even upload to App Store Connect. Yet I don't have a distribution certificate anywhere in my keychain. I therefore don't understand how this was possible. How could I create all those distributions without a distribution certificate in the keychain?

I've linked my contacts app on my iPhone to my company contacts database, and it shows up in the contacts app as "My Company Global Address List", and I can tap on it and search within it. However using CNContactFetchRequest doesn't retrieve any of those contacts, is it something that's possible to do, if so how?

Without exception, every single code example/tutorial for adding a contact group uses a nil container value i.e. the toContainerWithIdentifier parameter is nil, as below. I've not been able to find an example usage where it isn't nil. let group = CNMutableGroup() group.name = "whatever" let saveRequest = CNSaveRequest() saveRequest.add(group, toContainerWithIdentifier: nil) do { try store.execute(saveRequest) } catch { handle error } I've been running this code and 99.9% of the time it works as expected. However on one handset the catch is being executed with Error Domain=CNErrorDomain Code=207 "Container is read-only" How should I deal with this? How can I find out what container it is being added to? Why would it be read only? If nil means add to the default container, why is the default container in this case read only? How can I change the code that it will always run on every device? I've not been able to find any examples/tutorials for creating a custom container to which the group can be added.

In the past I've used lipo to remove unwanted architectures from fat frameworks, using lipo -remove. However when attempting to do similarly with a .xcframework I keep getting errors, its not just the -remove command. If for example I run lipo -info someFramework.xcframework then the error is: can't map input file: someFramework.xcframework (Invalid argument) if I cd into the xcframework and run lipo -remove ios-arm64_x86_64-simulator then the error is unknown architecture specification flag: ios-arm64_x86_64-simulator in specifying remove operation: -remove ios-arm64_x86_64-simulator

With Xcode 15 if you attach an iPhone (with iOS 17 installed) and then select Window|Devices & Simulators, then you can see the connected iPhone of the left hand side of the organizer. However with the iPhone selected, when the Open Console button is clicked it doesn't launch the console for the phone but instead for the Mac. There's therefore no way to view the handset logs (you can see the app logs within Xcode as per usual, but you can't view the holistic handset logs).

The Xcode 15 beta does not have a 17.* folder within Developer/Platforms/iPhoneOS.platform/DeviceSupport. How therefore does it build/install/run on a a phone with iOS 17 installed? Is there a different mechanism for device support used from 17 onwards than has historically been the case? I want to build/run using Xcode 14.n with an iOS 17 phone, but without being able to locate the iOS 17 support file am unable to do so. Where is the iOS 17 device support files with Xcode 15? How can I build using Xcode 14 for iOS 17 if its not present in Xcode15 (in order to drag and drop it into Xcode 14)

On my iPhone, in Settings, I've added my company Exchange account. Consequently, within the Contacts app, 4 new lists appear - the bottom as shown in the attached image. There's a few thousand contacts in the Company Exchange account, so why are the count values showing as 0? If I click on the Global Address list and search, it can succfully find whatever I search for. I want to programatically retrieve the contacts within the Exchange account, in addition to those stored locally or within iCloud, however if I execute the following code, for the container of type exchange, the count of results of the call to unifiedContacts() is 0. How can I programatically get the Exchange contacts? If the call to unifiedContacts() is resulting in 0 because the count for the lists when viewing the Contacts app is 0, then how to make it not 0 in the Contacts app (but if that were the case, how come manually searching for a contact is successful?) let keysToFetch = [ CNContactFormatter.descriptorForRequiredKeys(for: .fullName), CNContactPhoneNumbersKey, CNContactEmailAddressesKey, CNContactThumbnailImageDataKey] as [Any] var allContainers: [CNContainer] = [] do { allContainers = try CNContactStore().containers(matching: nil) } catch { print("Error fetching containers") } var results: [CNContact] = [] for container in allContainers { let type = container.type let identifier = container.identifier let fetchPredicate = CNContact.predicateForContactsInContainer(withIdentifier: container.identifier) do { let containerResults = try CNContactStore().unifiedContacts(matching: fetchPredicate, keysToFetch: keysToFetch as! [CNKeyDescriptor]) let count = containerResults.count results.append(contentsOf: containerResults) } catch { print("Error fetching containers") } }

My app has several app extensions and I'd like to be able to unify the logging between them such that they write to a single shared file (which can be read from and subsequently uploaded to things like Crashltyics or Bugsnag etc.) Its possible to log directly to things like Crashlytics, however none of them I've investigated have a unified approach for the app and extensions (for example, if you use Crashlytics you have to configure the app and the extensions separately, so any logging goes to two entirely separate consoles.) Hence, instead I'm wondering if there a library that provides the ability to log to a file, and that file can be shared and simultaneously written to (in the case where the app and its extensions are running simultaneously). Do any of the existing log libraries for iOS have this ability?

I'm getting loads of these appearing in my console, I can't find anything for it from googling. What does it mean?

In the console app, there is an option to turn on/off the displaying of Info and Debug message levels: However I don't see an equivalent to do likewise with Xcode's console. Is there one?

I've got a crash occurring at app launch time, its crashing too early for Crashlytics to have a chance to send off its stuff to its website. The person on who's phone it is crashing is tech savvy so we've managed to extract the Apple crash report and the Crashlytics directly full of loads of stuff. The Apple crash report is very useful, but I'd like to supplement the information obtained from the with that from Crashltyics (not the actual crash stack, Crashlytics can't improve on what Apple do) but some breadcrumbs that Crashlytics ought to have. I've opened all the files but there's nothing human readable, I asked this question of their customer support but they never replied. Anybody happen to know if the raw Crashlytics files can manually be munged into a human readable form, or manually uploaded to the Crashlytics web site?

Xcode has had the ability to debug app extensions for many years. However, several years ago it used to be so bad as to be unusable (extremely slow to load, very slow to run, and just utterly utterly unreliable). I'm glad to say this situation changed and for the past few years its been great, interactively running app extension with Xcode 14.2 or 14.3 is as stable and almost as quick as interacting with the main app. But unfortunately there's been a big step back in reliability in Xcode 15. Many times with Xcode 15 it just stops working, its just not possible to step into the code, stop at a breakpoint for app extensions. It's not like this all the time, sometimes it works just fine, but the problem is quite often it just stops working (by not working I mean breakpoints set in an app extension aren't hit, despite the path of control going through them and the extension being selected as the scheme to execute) The problem is once it stops working there's no way I've found to get it working again, restarting XCOde, rebuilding, restarting the phone, none of this works. Once Xcode has decided to stop working for debugging app extensions there's no apparent way to get it going again. It doesn't matter what type of extension it is - action extension, unwanted communication extension, notification service extension, ..... There's just something fundamentally regressed in XCode 15 that didn't exist with Xcode 14. Apple please can you investigate fixing this, it makes developing and debugging app extension impossible. At least are there any tips to try to attempt to reset Xcode to try and get it working again once its stopped interactively running the extensions?
