watchOS 2 new API summary
We read through all of the documentation, Xcode 7 header files, and tried to summarize everything we could figure out about watchOS 2. We hope this is a quick jumping off point for developers who just want a quick description and links directly into the Apple documentation. http://www.sneakycrab.com/blog/2015/6/8/watchos-20-tldrPlease give feedback, corrections and new discoveries, and we'll update the post with new information as we find it.

how to make external group for testers?
Hi, I'm trying to set up external testing for my iOS app on TestFlight but I can't find the External Testing option anywhere in App Store Connect. My setup: I'm the Account Holder I've uploaded two builds (build 128 via TestFlight Internal Only, build 130 via App Store Connect distribution) I have one internal group with myself added as a tester Both builds show as Complete The UI I see does NOT match the documentation. There is no sidebar with Internal Testing / External Testing sections. I access TestFlight via a dropdown at the top of App Store Connect, which takes me to an iOS Builds list. Clicking into a build shows Test Information, Groups, and Individual Testers — but no way to create an External group or find a public link anywhere. I've tried navigating directly to appstoreconnect.apple.com/apps/[APPID]/testflight/groups but get We can't process your request. Is there a new App Store Connect UI that has moved where External Testing lives? Is there anything else tha

Reply to Modal Presentation in UIKit Adds Solid Background in iOS 26
Is this change in modal presentation documented anywhere? I can't seem to find anything on it in the Apple Dev Documentation or from WWDC25. We don't document the implementation details, but the design change was mentioned in this video. (It is a SwiftUI video, but the design change applies to UIKit.) Best, —— Ziqiao Chen  Worldwide Developer Relations.

WWDC 2017 Apple File System Lab
These questions are community-driven. I am also not the original questioner, I'm just posting them with permission. Thank you to the anonymous folks who helped gather this information.Question: Will ASR continue to function with APFS? If not, will imaging via HFS+ (possibly converting to APFS afterwards) continue to be supported moving forward?Answer: Yes, ASR will continue to be supported.Question: Is fdesetup going to be the tool for interacting with APFS encryption, or will there be a new command line tool for managing APFS encryption? If there's a new tool, what is it?Answer: Yes, fdesetup is still the tool to use going forward.Question: Will the APFS per-file encryption / per-metadata encryption / per-extant encryption mechanisms each need their own recovery key?Answer: Full Volume Encryption for FileVault. Unclear on whether there are recovery keys when using e.g. per file encryption.Question: Can APFS recovery key(s) be escrowed when enabling encryption? The goal is to store the recovery key(s) somewhe

Move Group Crash Bug
Does anyone know a workaround for the well-documented bug that makes XCode crash whenever you move a group? This bug is reproducible 100% of the time and has been documented as far back as early 2017, yet I'm sure there must be a way to move a group. The only suggestion I've read is to turn off source control, but I'm unwilling to do so and lose my editing history. I've tried moving files into the group before moving it, moving it in different way, nothing works. And what's worse of course is that you have to reopen XCode twice after the crash to return it to a usable state.

Sign in with Apple for app group
I have a series of apps that use the same user database. With my Facebook and email/password logins this is easy to identify the same user. However, the sign in with Apple creates a different user_id for the same user across my group of apps. How do I allow the same user to login with the same user_id across the app group?

Single product in Subscription Groups
Hi iPhone Developper,This is Hayto from Tokyo, Japan. I am looking for how to make product without levels into subscription groups.As I am quoting as follows, I found the document which refers that we can make single product. But I can not find how we can set single product without levels into subscription groups or products with same levels.All subscriptions must be part of a group, however you are not required to differentiate them into levels. For example, you can choose to offer a single subscription in-app purchase, or you can choose to offer multiple subscriptions and assign them all to the same level within the group.URL which I quoted is as follows.https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnectInAppPurchase_Guide/Chapters/CreatingInAppPurchaseProducts.html#//apple_ref/doc/uid/TP40013727-CH3-SW10Could you kindly tell me how to make subscription product into subscription groups and how to make multiple products with same l

IAP subscriptions defaulted to different groups
Hi, In the new iTunes connect subscription groups feature, it seems Apple has defaulted to putting all of our In app purchase products into different groups. This is not what we want. We want them all in the same group so users can switch between them and we can maintain the 85% revenue share. I don't see any way to move subscriptions between groups. How can this be fixed? Thank you.

Unable to add build to group on testfight
In App Store Connect I've uploaded a new build, but I'm unable to distribute the App to my tester groups - including internal. The internal group is grayed out. I am able to Select an External group but they actually do not receive any email notification nor do they see any update within their TestFlight App. I've attempted to upload the build a few times, including old builds which had been distributed in the past to no avail. I'm not able to distribute to any tester group, please advise.

App Groups in Provisioning Profile
I'll preface by saying I am new to MacOS development. I've struggled with this issue for several days and have nowhere else to go for help. My MacOS app is an Electron build. It needs application-groups entitlement for IPC. But the developer portal, when generating the provisioning profile, always appends groups. to the start and I am unable to remove it. This renders my provisioning profile invalid and causes my app to be rejected by Transporter because it is not supposed to start with groups, but with my team identified for MacOS. Maybe I can still use the provisioning profile as is, but I've not found any way to do that. So I'm stuck unable to deliver. Any help with this is appreciated.

Change group for existing Renewable Subscriptions
I was wondering, we have already had Renewable Subscriptions items currently on sale on iTunes Connect, however, with iOS 10, the IAP group was introduced and I was wondering if it is possible to change the default group created in the iTunes Connect?If not and we have to create new items in the group, is it possible to migrate our user. (i.e unsubscribe from the current subscription group and move them to the new one)?Thank you

Here's what we said in WWDC25 Platforms State of the Union: As you evaluate your app's UI and the time you need to adopt the new design, we're providing an option to continue to use your app's current design with Xcode 26. We intend this option to be removed in the next major release. — Ed Ford,  DTS Engineer
