Hey all, my first time posting on these forums as I've finally become completely stumped. I'm working to implement a ShareLink to share data between users on my app, and have gotten pretty far (file saves, sends correctly), but am having significant issues getting the link to open in my app when sharing by email and not getting any action at all when tapping a shared link in iMessage. I'll go through my setup below: I have declared my new UTType, and created my new model which conforms to transferable here: struct transferTemplate: Codable { var id: UUID = UUID() var name: String = "TempName" var words: [String] = ["word1","word2"] } extension transferTemplate: Transferable { static var transferRepresentation: some TransferRepresentation { CodableRepresentation(contentType: .oltemplate) } } extension UTType { static var oltemplate: UTType { UTType(exportedAs: "com.overloadapp.oltemplate") } } I have declared the document type in my info.plist: <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeName</key> <string>Template Session</string> <key>LSHandlerRank</key> <string>Owner</string> <key>LSItemContentTypes</key> <array> <string>com.overloadapp.oltemplate</string> </array> </dict> </array> I have declared the Exported Type Identifier: <key>UTExportedTypeDeclarations</key> <array> <dict> <key>UTTypeConformsTo</key> <array> <string>public.json</string> </array> <key>UTTypeDescription</key> <string>Template Session</string> <key>UTTypeIconFiles</key> <array/> <key>UTTypeIdentifier</key> <string>com.overloadapp.oltemplate</string> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>oltemplate</string> </array> <key>public.mime-type</key> <array> <string>application/json</string> </array> </dict> </dict> </array> I've also included the "LSSupportsOpeningDocumentsInPlace" boolean to True in the PLIST. My physical ShareLink setup is: @State private var transferred: transferTemplate = transferTemplate(name: "NameTemplate", words: ["One","Two"]) ... ShareLink(item: transferred, preview: SharePreview("Share your template", image: Image("tanLogo"))) Heres where the above code gets you: ShareLink brings up the share sheet and allows you to send the file (with the .oltemplate file extension). Sharing via iMessage will send a file, but within iMessage, the file cannot be opened at all. By email, the file can be opened but does not show any information. If you open the ShareSheet within the email attachment, you can manually choose to open the file in my app. If the file is saved to "Files", it will open my app when it is tapped (work as intended). Heres what I have tried to fix this: Modifying the Exported File Type "Conforms to" value. Ive used public.data, public.text, public.json. Including and not including the mime type I've scoured forums trying to solve this issue, and it doesn't seem like there is a clear cut solution for this issue. I appreciate any help you can provide! Please let me know if I can include any more helpful information.

Hello Apple Developer Forums, We are building an iOS app that needs to receive images and PDFs shared from the system share sheet. The sources include Screenshots, Photos, Files, and third-party apps. The desired user experience is similar to apps such as ChatGPT or Claude: when the user taps our app in the share sheet, the main containing app opens and starts importing or uploading the shared image or PDF. We are trying to understand the supported public API for this behavior. Why opening the containing app is important For our use case, it is important that the containing app opens during the share flow. The import/upload operation depends on the user’s authenticated session. If the Share Extension attempts to upload the file directly, the auth token available to the extension could be missing, expired, or invalid. We would prefer not to make the Share Extension responsible for authentication-dependent behavior such as: validating the user session refreshing tokens handling expired credentials presenting login or re-authentication UI owning upload retry logic tied to auth state In our architecture, authentication and token refresh are owned by the containing app. The Share Extension should ideally only receive the shared file, persist it in an app group container, and hand off to the main app. The main app would then validate auth state, refresh tokens if needed, and perform the import/upload. So the desired flow is: Share Extension receives image/PDF → Share Extension stores file in app group container → Containing app opens → Containing app validates auth/session state → Containing app imports/uploads the file The alternative flow is problematic for us: Share Extension receives image/PDF → Share Extension attempts upload directly → Upload may fail if auth token is expired or unavailable → Share Extension would need auth/session responsibilities We are trying to avoid having an authentication dependency inside the Share Extension implementation. What we have tried CFBundleDocumentTypes We added document type support for: public.image public.png public.jpeg public.heic public.heif com.adobe.pdf This works for some document-open flows, such as opening files from Files or Photos in certain cases. However, it does not make the app appear reliably as a share target from Screenshot Share or from some third-party app share sheets. App Intents We tried using App Intents with IntentFile and: static var openAppWhenRun: Bool = true However, this does not seem to create a general-purpose share-sheet receiver for arbitrary image or PDF NSItemProvider payloads. Share Extension We also implemented a Share Extension that: Receives the shared NSItemProvider. Stores the image or PDF in an app group container. Attempts to open the containing app. However: NSExtensionContext.open(_:completionHandler:) does not appear to foreground the containing app from a Share Extension in the way we need. We also tested responder-chain openURL: trampoline approaches, but those do not work reliably and appear to be unsupported as a public API contract. Questions Is there a supported public API for an iOS app to appear as a share target for arbitrary image/PDF NSItemProvider payloads and then directly open the containing app? If apps such as ChatGPT or Claude appear to switch directly into the main app from the share sheet, is that behavior achievable using public APIs available to third-party developers? If directly opening the containing app is not supported, what is the recommended architecture when the import/upload depends on authenticated app state? Is Apple’s recommended design that the Share Extension itself must perform the full import/upload operation, even when that operation depends on auth validation or token refresh? Is there a supported handoff mechanism where the Share Extension can persist the file in an app group container and then ask the system to open the containing app to continue the flow? Are App Intents intended to support this kind of share-sheet attachment import flow, either currently or in a future iOS version? Reproduction Steps We created a focused sample project to reproduce the issue. Build and run the app on a physical iPhone. Leave the app installed. Capture a screenshot. Tap the screenshot thumbnail. Tap the Share button. Choose the app’s Share Extension from the share sheet. Observe that the Share Extension receives the image payload. Attempt to open the containing app from the extension. Expected Result The Share Extension receives the shared image or PDF, stores it in an app group container, and the containing app foregrounds. The containing app then validates the user’s authenticated session, refreshes tokens if needed, and performs the import/upload. Actual Result The Share Extension receives the image payload and logs the provider type identifiers, but the containing app does not reliably foreground. NSExtensionContext.open does not provide the desired transition, and responder-chain URL-opening workarounds do not appear to be supported or reliable. Minimal Question For image/PDF imports from the iOS share sheet, where upload/import requires authenticated app state, what is the supported implementation? Is it expected to be: Share Extension receives the file → Share Extension performs auth-dependent upload/import itself or is there a supported way to implement: Share Extension receives the file → Share Extension stores the file in app group container → Share Extension opens or hands off to containing app → Main app performs auth validation and upload/import Any guidance on the supported architecture would be appreciated. Thank you.

The question: Is there any chance that Apple will integrate Intune SDK into Apple apps such as Mail or Calendar, or create Siri-compatible Intune SDK-integrated versions of Mail and Calendar? The reason for the question: My team has been asked by VIPs in our company (e.g. execs and board members) if Siri can be used with Outlook, and the only way is through Shortcuts or by adding the Outlook account to Mail. Both of these options would violate our security policies for these reasons: Since our company policy and federal regulations don't permit us to allow access to company resources on non-MAM-protected apps, we can't allow our users to login to the Mail app and make full use of Siri, due to the lack of MAM controls for Mail and Calendar. We only allow users to transfer data between policy-managed apps which have integrated the Intune SDK allowing us to enforce DLP and other security measures. The only way to enable Shortcuts would be to disable these security measures.

I'm working with images selected from the iOS Photos app using PHPickerViewController. Some images appear as HEIF in the Photos info panel — which I understand are stored in the HEIC format, i.e., HEIF containers with HEVC-compressed images, commonly used on iOS when "High Efficiency" is enabled. To convert these images to JPEG, I'm using the standard UIKit approach: if let image = UIImage(data: heicData) { let jpegData = image.jpegData(compressionQuality: 1.0) } However, I’ve noticed that this conversion often increases the image size significantly: Original HEIC/HEIF: ~3 MB Converted JPEG (quality: 1.0): ~8–12 MB There’s no resolution change or image editing — it’s just a direct conversion. I understand that HEIC is more efficient than JPEG, but the increase in file size feels disproportionate. Is this kind of jump expected, or are there any recommended workarounds to avoid it?

Hello everyone, I'm trying to figure out how to transmit a UIImage (png or tiff) securely to an application running in my desktop browser (Mac or PC). The desktop application and iOS app would potentially be running on the same local network (iOS hotspot or something) or have no internet connection at all. I'm trying to securely send over an image that the running desktop app could ingest. I was thinking something like a local server securely accepting image data from an iPhone. Any suggestions ideas or where to look for more info would be greatly appreciated! Thank you for your help.

Hello, In our application, we have implemented an app extension to allow users to open the main app directly from the share activity window. To achieve this, we used the openURL(:) method from the NSExtensionContext class, as documented here: openURL(:). However, we received one post from Apple stating that opening the main app directly is typically only supported in extensions such as Today widgets or iMessage apps. They also mentioned that this approach may require an additional review during the App Store submission process. Link: https://developer.apple.com/documentation/foundation/nsextensioncontext/1416791-openurl Could someone clarify: If using openURL(_:) in a share extension to open the main app would lead to potential issues during App Store submission? Are there specific guidelines or alternative approaches we should follow to ensure compliance? Any insights or recommendations would be greatly appreciated. Thank you!

Hello! I’m trying to handle custom URLs (e.g., customurl://open?param=value) that open the app. However, while the app launches via the custom URL as expected, the parameters are not being passed to or are accessible from the iOS-specific implementation. Currently, if I open a custom URL via Safari, the app gets launched but the custom URL and parameters are not accessible. customurl://open?hello=test According to the iOS Docs ( https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Handle-incoming-URLs ) any URLs should be passed to: func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:] ) -&gt; Bool I do not register the above application function to be called but instead this one is executed during app start with launchOptions always being nil: func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -&gt; Bool This is the case regardless of if the App is started fresh or was already running in the background. My pInfo entry for the custom URL: &lt;key&gt;CFBundleURLTypes&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;CFBundleTypeRole&lt;/key&gt; &lt;string&gt;Viewer&lt;/string&gt; &lt;key&gt;CFBundleURLName&lt;/key&gt; &lt;string&gt;dev.customurl.project&lt;/string&gt; &lt;key&gt;CFBundleURLSchemes&lt;/key&gt; &lt;array&gt; &lt;string&gt;customurl&lt;/string&gt; &lt;/array&gt; &lt;/dict&gt; &lt;dict/&gt; &lt;/array&gt; TLDR: How can I access the parameters, passed with the URL? Any thoughts on what I am doing wrong?

My app monitors users heart beats and if critical reading is noticed, it auto -dials 911 for emergency and ambulance help. I was under the impression that auto-dial may not be permitted or possible on the platform. Can anyone confirm and provide any additional guidance on if it is possible in the newer SDK/API stack or using any 3rd party service ? Thank you in advance!!

Hi, I have developed iOS app using Cordova platform, now I am trying to open the upi app which is not happening. Can anyone guide me how to do this. From my app i am hitting the below URL location.href='phonepe://'

how to save the state of my APP when I open another APP so that It can restore when I re-open it? my app will use over 10mb memory so if I open another APP(my app will go background) it will closed at all. when I re-open it it will restart. but I do not want it I want if I open Page A and then it go background and when I re-open it it still is Page A and do not restart.

In my app SexyPeri (https://apps.apple.com/fr/app/id6738291985), I create an album with some pics Album is called SexyPeri Now, I wish to redirect the user from my app SexyPeri DIRECTLY to the album SexyPeri There is no doc about your scheme photos-navigation, or I didn't see it. Some guys retro-engineered it, but I couldn't make this work. photos-navigation://album?name=SexyPeri doesn't work. So my question is: how can I redirect to the album directly ?

Hi everyone, I am working on creating an NFC-enabled Apple Wallet pass but have been unable to get the NFC functionality to work. While the pass itself adds to Wallet without issues, the NFC feature does not activate. Here’s a summary of what I’ve done: 1. Developer Setup: Registered a Pass Type ID in my Apple Developer account. Generated and installed the Pass Type ID certificate. Installed the latest WWDR certificate. 2. Pass JSON Configuration: My pass.json file includes the following NFC configuration: "nfc": { "message": "Tap to unlock door", "encryptionPublicKey": "MY_ENCRYPTION_PUBLIC_KEY", "payload": "encrypted_nfc_payload" } 3. Testing Results: When the pass includes the nfc field, it adds to Wallet but NFC does not work. If I remove the nfc field, the pass works fine (minus NFC, of course). What I Need Help With: 1. A step-by-step guide for correctly implementing NFC in Wallet passes, including details about encryption, key generation, and any additional setup steps. 2. Information on whether there are specific device or iOS version requirements for NFC-enabled passes. If there are any prerequisites or specific configurations I might be missing, please let me know. I’d really appreciate detailed guidance or resources that could help resolve this issue. Thank you!

when my iPhone15 pro max upgrade to iOS18.1.1，it can not connect to hotPot of my lot device(os android5.1) any more and my iPhone12(iOS 18.1.1) has no issues. Both the 15 pro max and the iPhone12 works well with another device (OS android 10.0). had tried: 1.Forget Network (and re-add your desired Wifi network), 2.Reset Network Settings (under Settings/General/Transfer or Reset iPhone) 3.Turn Airplane Mode On then Off after a few seconds 4.Restart the iPhone. 5.Rest all setting 6.Disable VPN 7.close the the settings from rotating my WiFi address Did anyone have similar issues?

Here’s a suggestion: Apple should provide a feature for iPhone users to automatically log the specific time and date whenever they reset their phone. This log would allow users to easily track when resets occur. Additionally, Apple could enhance backup options by enabling users to restore any data lost during a reset. This might include automatic backups before each reset or a more intuitive process for recovering previously backed-up data.

I recently upgraded my iPhone 13 to iOS 18, and I'm facing two issues. I didn't get the call recording feature. When I make a call and the person picks up, the call recording icon is not showing. The option to take notes during a call has disappeared. Earlier, the notes option used to be available on the call screen itself. Please help fix these two issues, or let me know if it's possible to resolve them from my end.

Hi everyone, I recently updated my iPhone to iOS 18 and have been experiencing significant issues with my cellular network since then. The primary problems include: Random disconnections from the cellular network Frequent "call failed" errors during phone calls After some troubleshooting, I identified that these issues are related to the modem firmware. In an attempt to resolve this, I downgraded my iPhone to iOS 17.6, but the modem firmware remained unchanged and the problems persisted. Today, I updated to iOS 18.1, hoping it might address the issue, but unfortunately, it didn't help either. Has anyone else experienced similar problems? Any suggestions on how to resolve this issue or if there is an expected update to fix this modem firmware problem? Thanks in advance for any help or advice! IPhone 15 pro, iOS 18.1

I am developing an app and having trouble implementing NFC HCE functionality on iOS. From what I found, NFC HCE seems possible in the EEA, but I need help doing it in other countries. Is there any way to achieve this through a specific license or certification from Apple? Any guidance or references would be greatly appreciated.

Hi, can you help me please? I have downloaded the iOS 18 beta and on Tuesday I run in update. Since than my mobile service is not working. I can make calls and receive them, but there is no 5G at all. I turned on off the device , I have reset the network system. waiting for your recommendation 😊

Hello, we are currently developing a VPN application. Recently, we have encountered several cases where the Network Extension process terminates unexpectedly. We cannot find any related crash logs on the device, but we can find system SystemMemoryReset logs. The timestamps in these logs closely match (with millisecond accuracy) the times when our VPN process terminated unexpectedly. We have a few questions: 1.How is the SystemMemoryReset event generated, and can this event be avoided? 2.When a SystemMemoryReset occurs, can it cause our VPN background process to be killed or the system to reboot? 3.If the background process can be killed, what conditions need to be met for this to happen, and what methods can we use to prevent the VPN background process from being killed? 4.Based on these logs, does our application have any related issues (the process name is CorplinkTunnel)? Do you have any suggestions for modifications? SystemMemoryReset-2024-06-25-232108.log SystemMemoryReset-2024-06-29-025353.log SystemMemoryReset-2024-07-01-024655.log
