Messages

Resolved Issues

  • Fixed: Stickers (Memoji and 3rd party) might appear blank. (120994483)

Object Capture

New Features

  • A new manual bounding box flow is now initiated if automatic object detection fails to find an object, particularly in cases where there is no salient ground plane. In this flow, the user is expected to utilize the standard manual bounding box controls to indicate the bounding box of the object to capture by adjusting the provided starting box placed in the world in front of the user. You can determine if this mode has been activated by observing for the new element .objectNotDetected, which will be added to the ObjectCaptureSession’s Feedback set when the manual flow has been activated. You can use this to provide notification and/or instructions to the user about this manual box flow as desired. (113474123)

Resolved Issues

  • Fixed an issue where an ObjectCaptureView was incorrectly rotating the point cloud view in landscape UI orientations. (114248688) (FB13030239)
  • Fixed: PhotogrammetrySession creation on iOS is now significantly faster. (114458164)

Shared iPad

Resolved Issues

  • Fixed: Users might be greeted with a “Loading” screen in the Files app immediately after log in on a Shared iPad. (122092017)

Siri

New Features

  • Siri can respond in a combination of English and Hindi, depending on the primary language you use to interact with Siri. In the Settings app, go to Siri & Search > Language > English (India) and choose English & Hindi as the Preferred Response Language. Then ask Siri something in Hindi. (114742290)

StoreKit

New Features

  • In StoreKit testing in Xcode, a billing error StoreKit message will be sent when a subscription tries to renew while the Enable Billing Retry on Renewalsetting is enabled in the StoreKit configuration file. Use the messages listener API to control when StoreKit messages are displayed in your app. (101869442)
  • productDescriptionHidden(_:) API can be used to configure the visibility of product descriptions in ProductView, StoreView and SubscriptionStoreView instances within a view hierarchy. When building with Xcode 15.3, the view modifier can be used even if your app is running on iOS 17.0, iPadOS 17.0, macOS 14.0, tvOS 17.0, watchOS 10.0, visionOS 1.0, or later.
    When implementing a product view style, it can support this new view modifier by checking the descriptionVisibility property on the configuration value. (110414819) (FB12261973)
  • You can use SubscriptionStoreView to present promotional offers by adding the subscriptionPromotionalOffer(offer:signature:) modifier.
    If you’re already using inAppPurchaseOptions(_:) modifier to support promotional offers for StoreKit views, you should adopt the new API instead when your app is running on iOS 17.4, iPadOS 17.4, macOS 14.4, tvOS 17.4, watchOS 10.4, visionOS 1.1 or later. Do not use both APIs to apply a promotional offer for the same view. (115358806)

Resolved Issues

  • Fixed: The isEligibleForIntroOffer property and isEligibleForIntroOffer(for:) method now reflect ineligibility in cases where a customer would otherwise be eligible for the offer if they weren’t actively subscribed. This means a customer which is not currently eligible for an introductory offer may become eligible in the future.
    Customers who redeem an introductory offer for a given subscription group will continue to never be eligible for another introductory offer in that subscription group. You can detect this case this by checking if any one transaction with a matching subscriptionGroupID has the type property on offer set to introductory. (103604770) (FB11889732)
  • Fixed an issue causing SKAdNetwork versions 2.2 and 3.0 to not accept impressions or send postbacks. (121223565)
  • Fixed an issue causing some approved Ask to Buy purchases to fail. (121249405)

SwiftUI

New Features

  • Table now supports dynamic numbers of columns with the new TableColumnForEach. (79492167) (FB9189673)
  • Popover presentations now automatically dismiss if they go outside the safe area. (100811375)

Resolved Issues

  • Fixed: Resolved an issue with programmatically present an alert or sheet simultaneously with dismissing another sheet. The new alert or sheet would not show but now it will. If you have code that presents the same sheet programmatically from multiple places in your view hierarchy at the same time, that sheet might no longer appear. Make sure that any sheet modifiers that are in the view hierarchy at the same time use distinct isPresented or item bindings. (117475214)

WebKit

Resolved Issues

  • Fixed HTML content not displaying in a Simulator, affecting projects using the web extension project template. (121338366)

Did anyone else’s app version of the Apple TV remote stop being able to find your Apple TV? Mine has been stuck on the “Searching…” spinner every time I tried using it since updating to 17.4

Will try out Podcast transcripts and also the new emojis. The new battery health section is also good along with call identification.

sorry to hear you’re having such problems - it always sucks when an update doesn’t go smoothly!

are you in the EU/one of the countries affected by the new App Store changes? maybe banking/etc apps that check for “jailbroken” devices incorrectly detect the new iOS (with EU changes) as jailbroken? hard to know how a banking app detects “jailbroken”, so probably hard to figure out the exact cause.

i think in the past, jailbreaking would allow normal apps to do things that they aren’t normally allowed to do (like writing to system files). that’s how some apps would detect jailbreaking - if the OS allowed them to (for example) write to system files, then it’s clearly not a ‘stock’ iOS install. I’m sure the EU changes don’t allow you to write to system files, but maybe there’s something else that was ‘illegal’ in older iOS versions that is now allowed in the EU 17.4?

if so, this is an unfortunate side-effect of the new EU rules. presumably (eventually), banking/etc apps will be updated to recognize the new iOS.
Yes, in the UK and had the 17.4 update show description concerning new EU related App Store changes.
I began the update at 35% battery and it was plugged in, let it boot up and didn't touch it for a while until it was 80%, then went to App Store, force refreshed to check for updates to ensure all apps were updated.
Loaded a few apps, noticed they were crashing, loaded another one which accused me of using a jailbroken device :D though doing a forced restart would fix it, instead it never booted up again so I was forced to do a Restore, which erased all content and settings.

Same. It would be nice to be able to use something other than what Safari is built on, and maybe to have an ability for extensions.
For me, third party browser engines would have the potential to make my “iPad Pro” actually be a Pro device. I create, code, and test things on the web. It would be nice if I could actually do that all from my iPad. It would also be nice to have Visual Studio Code, which is Chromium based on my iPad.

I am in the EU and I have an opposite question - where can I actually try side-loading? 😉
Just get some app outside of the App Store. There are thousands for years, and I'm pretty sure at this point there's dozens of alternative stores. Just check on wherever jailbreaking is a topic, I'm sure the community is all over this.

Apple did not adopt sideloading as their EU solution. Limited sideloading is still available via TestFlight and Xcode.
I'm aware of this.

Apple's solution for the EU is alternative App Stores. Don't download and create an account with an alternative App Store and then you won't be able to use it.
So it's actually disabled by default if you don't install any alternative store and what prompts the system to work is installing one? I'm not going to install any others stores, I'm just concerned this will be exploited in a way that'll lead people to unknowingly approve installing an app that may or may not contain malware. I'm pretty sure this will be exploited, I'm just not sure if my fears are out of proportion and/or if I/we can be targeted.

So you think we can go ahead and install any .ipa file we can find?

I updated my 15 Pro Max, then realised some apps are refusing to load because it thinks it's a jailbroken device, and others kept crashing on launch. I forced a restart, it got stuck in a boot loop. Contacted apple support, they said to connect it to a Mac and Update, but Update didn't work, so now I am being forced to do a factory reset/Restore.
What a complete and utter nightmare, this update is a disaster.
Same thing happened to me! I was updating my iPad Air (4th gen), it failed with "unknown error", only options to Update or Restore. Both of these also throw "unknown error" right at the end of the process.

I just got back from the local Apple Service Provider who says it's unfixable and I have to buy a new iPad. I'm furious.

He’s not there to help you fix your problems. He’s only there to sell stuff.

I bet he just said it’s not fixable - and knows that it is - to try to convince you to buy a new iPad from him.

It’s a bit like a car salesman saying if you have a flat tyre you need to buy a new car.

Well no. You don’t.

Gotta be in it to win it
My impressions:
- On my 15PM it took a few minutes to load
- Battery life is very good
- Navigation is fast and fluid
- I didn't have any issues with wireless connectivity so no change there
- Telsa bluetooth key seems to be working better than on 17.3.1
- All in all a fairly good update

I should’ve taken my own advice, iOS 17.4.0 is a hot mess, they really rushed it for the EU deadline, I don’t know how an email application changes have anything to do with the EU regulations.

The latest snafu is it scrambles your emails, when you look at the reply to address it can show email addresses from other emails.

My brother made a mistake of hitting reply all and it was sending emails to people that it wasn’t even related to.

The only way to fix it is to quit and launch mail but it keeps coming back, if you’re using the email program always check your other address fields before sending.

Example:
It’s mixing my Cracker Barrel email address with my Adobe account.
