Cannot load developer teams in Xcode.
Hi, The ui error says unable to login, but I'm able to login (because if I don't give the correct password it's a different error). When Xcode tries to fetch the available teams though it errors out. I can successfully login and access my teams on a different machine that's on the same network. So I know the account and network are fine. Here's what the ui shows .. and I'm also including the Xcode logs from Console. Any ideas? Thanks! xcode.log

How to call API of tested app in UI Testing of Xcode7?
Hi guys, recently I've been investigating new UI Testing in Xcode7. There seems to be limited APIs we can call direct in UI test. Can I include header files and call public API of my tested app in UI Test? so that I can have more flexibility to set my app status before running test. I intent to call API method "-(void)reloadURL:(NSURL *)url" of my app in UI Test, but test failed with "XCTRunner -[_XCTRunnerAppDelegate myAppDelegateUtils]: unrecoginzed selector sent to instance 0x7cf0a992fe10"In Unit Test we can call any API of the tested app, does it support in UI Testing too? I'm a start learner of Xcode and its testing...could anyone help to answer this question? Thanks!

Is SFSymbol Customization officially valid as a method for using SVG in embedded widgets (lock-screen & watchOS)?
Is SFSymbol Customization officially valid as a method for using SVG in embedded widgets (lock-screen & watchOS)? I use this in UnitedPizzaHelper but wonder whether this is the prime cause why all widgets of this app gets missing on iOS devices? This issue only happened on at least 2 device in the recent 12 months (they are all on iOS 18, and one of them is running iOS 18.5... Rebooting device won't work.), and we currently have no clue how to troubleshoot this. Update: The guy running iOS 18.5 told me that the widgets are now discoverable after waiting for minutes. Seems that this is a random issue.

Xcode 16.3 Compile fails
After updating to 16.3, my project now fails to compile with the diagnostic: "Command SwiftCompile failed with a nonzero exit code". This is a SwiftUI document project with two local packages, the second of which is a rather large one with 112 SwiftUI files. It is this second package that is failing. There are no issues when compiling with 16.2. Without diagnostics I'm having a bit of difficulty in determining the cause. My thought is to regress the commits unit 16.3 gives a success, or shows issues. Although I'm not catching a similar issue in the forums, I'm seeing other problems with 16.3. Has anyone else had such build failure isolated to 16.3? Any advice on other ways to approach this problem? Thanks in advance

❗️Xcode-beta: “missing required module ‘SwiftShims’” and C99 PCH conflict
Hi all, I’m running into a persistent build issue with my Swift project ORSOFINAL after migrating from Xcode stable to Xcode-beta.app 26 (June 2025 version). ⸻ 💥 Errors displayed: 1. C99 was enabled in PCH file but is currently disabled 2. module file .../ModuleCache.noindex/SwiftShims-AXUM98L131W4...pcm cannot be loaded due to a configuration mismatch with the current compilation 3. missing required module 'SwiftShims' ⸻ 🛠 What I’ve already tried: • xcode-select -s /Applications/Xcode-beta.app/Contents/Developer • Deleted ~/Library/Developer/Xcode/DerivedData, ModuleCache.noindex, Archives, and Products • Ran sudo xcodebuild -runFirstLaunch • Clean Build Folder in Xcode-beta • Verified Command Line Tools setting points to Xcode-beta ⸻ ❓Looking for guidance on: • Whether this is a known bug in Xcode-beta • If SwiftShims/PCM conflicts are expected between versions • Best practices to safely migrate from Xcode stable to beta for Swift-based projects Any advice is much appreciated.

Xcode Test Pane for TDD and Unit Tests?
At the last place I worked it took roughly 5 minutes to do an application build. Which in turn made doing any sort of TDD or ever just regular Unit Tests extremely painful to do as the cycle time was simply too long. But that got me thinking. In recent versions of Xcode, Apple added Previews for SwiftUI Views that basically showed code changes to the View in real time. And Previews were made possible by extremely targeted compilation of the view in question. So... what if instead of a Preview pane in the Xcode IDE there was a Test pane the could be displayed such that Tests for a piece of code could be created and run almost immediately? Perhaps by adding a #Testing section to your code #Testing(MyService.self) // Define the entity to be tested. If you could drop the turnaround time AND provide a test playground for service level code that could speed development of such code greatly... and encourage interactive test development at the same time. What do you think?

Does Xcode force to download latest iOS simulator after update?
I have Xcode on my mac. I am iOS Dev. I do not know what version of Xcode was before I did next steps, but I could say that I had iOS Simulator 18.3.1. So I update my Xcode to Version 16.3 (16E140). At this version is available iOS Simulator 18.4. But from some time before Xcode separate downloading components and actual Xcode itself. So i make update and do not download latest iOS simulator. What i have: in Xcode -> Settings -> Components under " Other Installed Platforms" i have iOS 18.3.1 and 17.5 in Choose Destination dropdown menu i have nothing. And Xcode say me that i need install iOS Simulator. After some time with ChatGPT I could not do nothing from this. I try go to : Window -> Device and Simulators and here create new simulator with 18.3.1 and make it appear Always. But it didn't help. Solution I did: I download latest version 18.4 because i could not wait because i need fix bug only 1 hour shift and it was this hour so i fast download the simulator. After downloading 18.4 in Choose Destination dropdown it appears all versions of simulaors and 18.3.1 and that i created and 17.5 Question: Does Xcode force to install latest version of iOS simulator? What is the sense of this upgrade that now Xcode is updating faster because it download 8 GB not 16 if eventually I need download 8 GB again ? The new what i could do download Xcode in the evening and Simulator in the morning?

App Clip cannot determine the source of the opening
Our business is to scan the code to open App Clip, but then App Clip will appear in App Library and Siri Suggestions. This can be opened quickly, but the URL of the last scan will be included. This will cause a problem, for example: if the previous scan was code A, but the user does not scan code B when going to place B and directly opens it through App Library or Siri Suggestions, the code I get is still code A, so the result I want is that I want to know where it was opened from, and then if it is opened quickly, I will clear the URL and remind the user to scan the code again. Or if it is opened by quick opening, do not include the URL

One of my recent version metrics disappear in Xcode organizer metrics
Hello, For one of my recent release (2 versions ago), I used to be able to check its p50 of Hang Rate, but now it disappear and not showing up in XCode Organizer Metrics anymore. The p90 of Hang Rate of this version is still there. It's so unpredictable. Is there something we can do to get this data to populate? If not, may I understand usually why this issue will happen, is it something frond-end bug or is it because there is some thing abnormal going on in the back-end data?

ISO 14443-4 Reading issue
I am working with a Texas Instruments RF430 NFC tag, which is compliant with: ISO/IEC 14443-4 (ISO-DEP) NFC Forum Type 4 Tag NFC-B protocol NDEF-formatted storage I’m using an iPhone 12 running iOS 18, and my app uses the Core NFC framework. Using NFCNDEFReaderSessionDelegate, I am able to successfully read the first NDEF message from the tag. However, the tag stores multiple NDEF messages, and I would like to access the others. Based on the tag’s specification, these messages are accessible via an NDEF file located at file ID 0xE104. To try and access this additional NDEF file, I attempted to use NFCTagReaderSession with the NFCTagReaderSessionDelegate, intending to issue APDU commands. However, the tagReaderSession(_:didDetect:) delegate method is never called, even though the tag is present and detected using NFCNDEFReaderSession. My questions: Does Core NFC on iOS 18 support issuing custom APDU commands to ISO 14443-4 (NFC-B) tags like the TI RF430? Is the use of NFCTagReaderSession with NFC-B fully supported for tags that implement ISO-DEP (even if they are NDEF-formatted)? Is there any known limitation or configuration required to ensure tagReaderSession(_:didDetect:) is triggered for NFC-B/ISO-DEP tags?

However, the tagReaderSession(_:didDetect:) delegate method is never called, even though the tag is present and detected using NFCNDEFReaderSession. My questions: Does Core NFC on iOS 18 support issuing custom APDU commands to ISO 14443-4 (NFC-B) tags like the TI RF430? Is the use of NFCTagReaderSession with NFC-B fully supported for tags that implement ISO-DEP (even if they are NDEF-formatted)? Is there any known limitation or configuration required to ensure tagReaderSession(_:didDetect:) is triggered for NFC-B/ISO-DEP tags?
