Hello, my son's iphone 14 plus has an infuriating problem. He has a physical sim card for a Belgian carrier. When he enters Belgium his signal nornally works but then if it drops for whatever reason (in a train, car, cellar) it doesn't come back. We have to remove the sim, put it in another phone and then put it back in the iphone. Is this a known issue? Does anyone have any smart fixes? (we have tried network resets and the sim works on other phones, including my old android brick)

Is there a way to acces the hostfile in iPhone/iPad? if Yes, How can we edit a host file in iphone device?

I don't see any current posts about the warning that says "PosterBoard quit unexpectedly." on my Mac. Older posts say this is an error generated by Xcode Simulator. I tried one of those solutions but I still see this warning coming up. I am also not using Simulator. I'm using an actual device - an iPhone 13 Pro Max running iOS 16.6. When I click on Reopen in that alert box telling me that warning message, I get a warning in an alert box with a picture of the Finder icon on it, and it says "You can’t open the application “PosterBoard.app” because this application is not supported on this Mac.". Anyone else have this problem and know what do do about it? Like fix it or get around it?

I got this iPhone 14 in Product Red, 128 GB in February 2023, the same year I'm posting this. I've mainly used it for taking photos and calling my partner, with less than 8 apps and around 1,000 photos stored. I always use the original cable for charging and don't play games in the phone (TBH, I don't have any games in this phone) that could harm the battery. However, the battery health has dropped to 93%, which is lower than expected for just 6 months of use. While some may argue that this figure is still quite acceptable, it falls short of what I anticipated for a new device with only six months of usage. I can draw a comparison with my previous phone, my previous phone, an iPhone SE 2021, endured heavy gaming for 12 hours a day and didn't have such a battery drop in the same timeframe. I'm genuinely curious if there's an issue with this new phone, even though I follow charging best practices by not going above 80% or below 20%.

I built a few homemade iOS Web Apps that I built with Xcode. I somehow was able to get them on my old iPhone 13. They are in IPA format. I upgraded to a 14 and need help reinstalling them. I've tried using Apple Configurator as well as just dragging them through the finder, but keep getting the following error: "This app cannot be installed because its integrity could not be verified." I tried going into the Device management to trust the profile, but no profiles are shown. Like I said, I had them on there before. I just don't know how I did it. Please be specific and detailed with your instructions. This project was me experimenting to see if becoming a developer is in my future. Clearly I'm not meant for this. Thanks in advance.

what is model name of first iphone using bluetooth Low Energy in iphone series ? i asked this question to chatGPT, i got a answer that the name of first iphone using BLE is iphone 4S. is this right ? if it is right, i think the assumption that iphone models after iphone 4s support Bluetooth Low energy communication is right.

I have set the iPhone device settings to deny the use of the Safari camera. (Settings app>Safari>Camera>"Deny") When selecting a file on a website and choosing "Take Photo", the camera can be activated. Devices tested iPhone SE (2nd generation) iOS 16.5 iPhone 7 iOS 15.7.3 iPhone 13pro iOS 16.5.1 But, Chrome is able to deny it successfully. Do you know if this is using Safari or a glitch? And, do you know how to make the rejection work in Safari as well?

is it possible to prioritise the app contact over the device contacts while registering caller id via CXCallDirectoryManager ? If i'm registering a phone number with name john from my app. it that phone number is already mapped to name johny. then johny is displayed as callerid. Any way to prioritise the app's caller id.

I am writing to complain about an issue with my iPhone 11 screen. I have had the phone for over a year and have taken good care of it. I have never dropped it or gotten it wet. Recently, I noticed that a line had appeared on the screen. The line was thin and white, and it was located at the top of the screen. The line has been growing slowly over time. I have tried restarting my phone, but the line has not gone away. I have also tried updating my phone's operating system, but that has not fixed the problem either. I am concerned that the line is a sign of a more serious problem with the screen. I would like to request a replacement screen for my phone. I would appreciate it if you could look into this issue and provide me with a solution. Additional information: I have attached a photo of the line on my phone's screen. Thank you for your time and consideration.

On downloading the app from app store everything works But, when I close the running app and launced it and it crashes. The app works fine in test environment and on appceter where it was tested but crashes on the restart of the app. On Examing the crash logs on xcode these are the logs which are hard to interpret. The crash log tool does not catch any crashes as well. The app is written in Xamarin. Does anyone have any suggestions? It is working fine on all my devices and on simulators. Here are some logs from the crash log. 30 UIKitCore 0x1c1bf1a50 -[UIApplication _handleDelegateCallbacksWithOptions:isSuspended:restoreState:] + 300 31 UIKitCore 0x1c1bf1174 -[UIApplication _callInitializationDelegatesWithActions:forCanvas:payload:fromOriginatingProcess:] + 2848 32 UIKitCore 0x1c1bf0150 -[UIApplication _runWithMainScene:transitionContext:completion:] + 856 33 UIKitCore 0x1c1befd9c -[_UISceneLifecycleMultiplexer completeApplicationLaunchWithFBSScene:transitionContext:] + 132 34 UIKitCore 0x1c1935e74 _UIScenePerformActionsWithLifecycleActionMask + 108 35 UIKitCore 0x1c1c77d78 __101-[_UISceneLifecycleMultiplexer _evalTransitionToSettings:fromSettings:forceExit:withTransitionStore:]_block_invoke + 216 36 UIKitCore 0x1c1b28adc -[_UISceneLifecycleMultiplexer _performBlock:withApplicationOfDeactivationReasons:fromReasons:] + 220 37 UIKitCore 0x1c1b28904 -[_UISceneLifecycleMultiplexer _evalTransitionToSettings:fromSettings:forceExit:withTransitionStore:] + 620 38 UIKitCore 0x1c1b284b4 -[_UISceneLifecycleMultiplexer uiScene:transitionedFromState:withTransitionContext:] + 252 39 UIKitCore 0x1c1b28380 __186-[_UIWindowSceneFBSSceneTransitionContextDrivenLifecycleSettingsDiffAction _performActionsForUIScene:withUpdatedFBSScene:settingsDiff:fromSettings:transitionContext:lifecycleActionType:]_block_invoke + 148 40 UIKitCore 0x1c220c56c +[BSAnimationSettings(UIKit) tryAnimatingWithSettings:fromCurrentState:actions:completion:] + 736 41 UIKitCore 0x1c22a6568 _UISceneSettingsDiffActionPerformChangesWithTransitionContextAndCompletion + 224 42 UIKitCore 0x1c19d4374 -[_UIWindowSceneFBSSceneTransitionContextDrivenLifecycleSettingsDiffAction _performActionsForUIScene:withUpdatedFBSScene:settingsDiff:fromSettings:transitionContext:lifecycleActionType:] + 316 43 UIKitCore 0x1c1e47294 __64-[UIScene scene:didUpdateWithDiff:transitionContext:completion:]_block_invoke.214 + 556 44 UIKitCore 0x1c1aa69a0 -[UIScene _emitSceneSettingsUpdateResponseForCompletion:afterSceneUpdateWork:] + 216 45 UIKitCore 0x1c1aa6810 -[UIScene scene:didUpdateWithDiff:transitionContext:completion:] + 244 46 UIKitCore 0x1c1aa5d64 -[UIApplication workspace:didCreateScene:withTransitionContext:completion:] + 520 47 UIKitCore 0x1c1aa5af0 -[UIApplicationSceneClientAgent scene:didInitializeWithEvent:completion:] + 288 48 FrontBoardServices 0x1d5444e90 -[FBSScene _callOutQueue_agent_didCreateWithTransitionContext:completion:] + 344 49 FrontBoardServices 0x1d54848f8 __92-[FBSWorkspaceScenesClient createSceneWithIdentity:parameters:transitionContext:completion:]_block_invoke.78 + 120 50 FrontBoardServices 0x1d5448c24 -[FBSWorkspace _calloutQueue_executeCalloutFromSource:withBlock:] + 168 51 FrontBoardServices 0x1d5484530 __92-[FBSWorkspaceScenesClient createSceneWithIdentity:parameters:transitionContext:completion:]_block_invoke + 360 52 libdispatch.dylib 0x1c6ce4f88 _dispatch_client_callout + 20 53 libdispatch.dylib 0x1c6ce8a08 _dispatch_block_invoke_direct + 264 54 FrontBoardServices 0x1d5452d40 FBSSERIALQUEUE_IS_CALLING_OUT_TO_A_BLOCK + 52 55 FrontBoardServices 0x1d54528dc -[FBSSerialQueue _targetQueue_performNextIfPossible] + 220 56 FrontBoardServices 0x1d5455184 -[FBSSerialQueue _performNextFromRunLoopSource] + 28 57 CoreFoundation 0x1bf798f24 CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION + 28 58 CoreFoundation 0x1bf7a52fc __CFRunLoopDoSource0 + 176 59 CoreFoundation 0x1bf7291c0 __CFRunLoopDoSources0 + 244 60 CoreFoundation 0x1bf73eb7c __CFRunLoopRun + 836 61 CoreFoundation 0x1bf743eb0 CFRunLoopRunSpecific + 612 62 GraphicsServices 0x1f9939368 GSEventRunModal + 164 63 UIKitCore 0x1c1c39668 -[UIApplication _run] + 888 64 UIKitCore 0x1c1c392cc UIApplicationMain + 340

My Iphone 13 is running in IOS 17 Public beta 6, recently I am noticing while using Whatsapp Status (only whatsapp) when I try to decrease volume in status its kind of not working, After that while I open Whatsapp i could see my volume goes or down and even when I come out the whatsapp the ringer volume goes up and down. I need to restart my phone to over come but this problem is consistent. My whatsapp is also upto date (and not an beta user). Pls suggest for any resolution.

Hello, everyone, for a few weeks now I've been trying to make a full backup of my iPhone by connecting it to my Mac with a data cable. Unfortunately the problem is always the same: it takes about 12/13 hours to get almost to the end but then it freezes. I am currently using the latest beta of iOS 17 and the latest version of macOS Ventura. How can I fix this? Thanks!

Hello, I am interested in developing an iOS app that can monitor and potentially block third-party applications while a specific app is running. I would like to inquire about the feasibility of implementing such functionality within the iOS ecosystem and if there are any privacy terms or restrictions that I need to be aware of to ensure compliance with Apple's policies. Thank you for your guidance.

Hello, I am interested in developing an iOS app that can monitor the names of third-party applications running in parallel without collecting any user-specific data. I would like to inquire about the feasibility of implementing such functionality within the iOS ecosystem and if there are any privacy terms or restrictions that I need to be aware of to ensure compliance with Apple's policies. Additionally, I want to emphasize that the app will not collect any user-specific data but only the names of third-party apps for operational purposes. Thank you for your guidance.

Good morning, my company needs to develop a screen reader (like VoiceOver more-or-less) with added custom features for blind people. I wanted to know if there's any possibility to implement a third-party screen reader on iOS, or if someone could suggest any workaround for it. Thank you

From recent days we are facing a serious random crash issue in our iOS app related to UICollectionView. We are having listing page where we have 4 sections with different data model. We have faced the below crash issue which happened all times when we update collection view. NSInternalInconsistencyException - Invalid update: invalid number of items in section 3. The number of items contained in an existing section after the update (60) must be equal to the number of items contained in that section before the update (40), plus or minus the number of items inserted or deleted from that section (0 inserted, 0 deleted) and plus or minus the number of items moved into or out of that section (0 moved in, 0 moved out). With below solution if #available(iOS 15.0, *) { if isPagination { var paths = [IndexPath]() for item in 0..<(localResult.products?.items ?? []).count { let indexPath = IndexPath(row: item + self.productItemData.count, section: 3) paths.append(indexPath) } self.productItemData.append(contentsOf: localResult.products?.items ?? []) self.mainCollectionView?.insertItems(at: paths) } else { self.productItemData.append(contentsOf: localResult.products?.items ?? []) } } else { self.productItemData.append(contentsOf: localResult.products?.items ?? []) } With the above solution, crash which happened all times when we update the collection view is resolved. But now, we are facing with another new issue as below and this is happening randomly based on different data set. This crash log is becoming the highest one and its affecting our app performance very seriously. And its happening with mostly above iOS 15. Is there any gap that we missed with latest iOS version update and why its happening without any much code change? Any better solution will be appreciated. Latest crash details: NSInternalInconsistencyException - attempt to insert item 20 into section 3, but there are only 3 sections after the update NSInternalInconsistencyException - Invalid batch updates detected: the number of sections and/or items returned by the data source before and/or after performing the batch updates are inconsistent with the updates. Data source before updates = { 4 sections with item counts: [1, 1, 1, 340] } Data source after updates = { 4 sections with item counts: [1, 1, 1, 340] } Updates = [ Insert item (3 - 320), Insert item (3 - 321), Insert item (3 - 322), Insert item (3 - 323), Insert item (3 - 324), Insert item (3 - 325), Insert item (3 - 326), Insert item (3 - 327), Insert item (3 - 328), Insert item (3 - 329), Insert item (3 - 330), Insert item (3 - 331), Insert item (3 - 332), Insert item (3 - 333), Insert item (3 - 334), Insert item (3 - 335), Insert item (3 - 336), Insert item (3 - 337), Insert item (3 - 338), Insert item (3 - 339) ]

I've received a latter from a law firm advising me that my app is infringing on their client's BWE patents. Specifically, the app uses the smartphones sensor based technology without a proper licensing agreement. Has anybody every heard that an app has to pay licensing fees to using the technology with a smartphone?

Dear community, I've been learning Swift, currently reading "Development Swift Fundamentals" (page 484). I have added 2 items to the tab bar controller. If I use one of the default "system items" (icon+label), it works fine in the simulator. However, if I change that to "Custom" and choose a different icon from the "Selected Image" menu, it shows that normally in Xcode but it does not show that at all in the Simulator or in my iPhone. Please see the images attached. Any thought? Please find below how I see that in the Simulator (or in my iPhone): Thanks, Rodrigo
