Issue with StoreKit 2 Purchases: "unfinalized statements / unfinished backups" SQLite Crash
Hi, I’m running into a persistent error while implementing StoreKit 2 renewable subscriptions in my SwiftUI app. Context I have a two-screen flow: Screen 1: user selects a subscription plan (monthly / yearly). Screen 2: user fills out personal information and taps Subscribe that triggers the purchase function. On first launch or the first couple of purchases (on both Storekit's local and Sandbox testing), everything works fine. The App Store popup appears, the purchase goes through, and I get the transaction result. But after a few runs (3rd or 4th purchase attempt onward), my app crashes the moment the App Store purchase popup appears. Error Logs When the crash happens, the console shows: `unable to close due to unfinalized statements or unfinished backups BUG IN CLIENT OF libsqlite3.dylib: database integrity compromised by API violation: vnode unlinked while in use: /private/var/mobile/Containers/Data/Application/D8D97A11-DF06-4EF2-AC55-138C4739A167/Library/d6d2e85a60f0480c4c17834eeb827a14_MPDB.sqlite invalidated open fd: 21 (0x11) BUG IN CLIENT OF libsqlite3.dylib: database integrity compromised by API violation: vnode unlinked while in use: ...` Observations The error only shows after some time maybe due to multiple transactions and switching between plans for the same user, not on the very first purchases. If I land on the purchase screen immediately after app launch, the purchase works. But if I wait a while before navigating to the purchase screen, the popup causes the app to crash. I’m not using Core Data or my own SQLite database at all - so I assume this DB (MPDB.sqlite) is StoreKit’s internal persistence. Things I’ve tried so far Cleaning StoreKit caches: rm -rf ~/Library/Developer/CoreSimulator/Devices/*/data/Container s/Data/Application/*/Library/Caches/storekit Rebuilding from scratch, cleaning build folder. Switching between sandbox accounts, signing out/in again. Added await transaction.finish() after verified purchases. Added cleanup for unfinished transactions at app launch: for await result in Transaction.unfinished { if case .verified(let transaction) = result { await transaction.finish() } } Tried both StoreKit Configuration file and sandbox environment but issue persists in both. Questions Is this error StoreKit-specific (internal SQLite DB corruption) or something wrong in my implementation? Why would it only appear after a few runs / with a delay before navigating to the purchase screen? Am I missing something else in handling StoreKit 2 transactions? Screenshots of the errors are attached for context. Any insights would be really appreciated...I’m stuck because I can’t tell if this is an Apple bug with StoreKit 2 or something I’ve overlooked in my code. Specs: Xcode 16.4 Build version 16F6 iOS version: 18.6.2

"Build input file cannot be found" error occurs in Archive.
"Build input file cannot be found" error occurs in Archive. When running Archive to generate a build file, the build file generation fails with a "Build input file cannot be found: ..." error. When debugging, the build runs fine on the actual device without any errors. Comparing and modifying the Build Settings with other projects doesn't fix the issue. Deleting the Swift file and attempting to Archive results in a crash due to the missing file. Even after deleting and adding the Swift file, the same error persists when attempting to Archive. Even after deleting and re-adding the Swift file, the issue persists even after deleting all DerivedData file space on my Mac and restarting Xcode. Can you help me with this issue? It worked fine before the recent macOS update, and I successfully archived and published it to the App Store a few days ago. I believe this issue occurred after updating macOS to 26.0.1. My Xcode version is 26.0.1.

Xcode 15 performance tests ignore baseline
I'm trying to write performance tests with Xcode 15, but it's not working: even though setting a baseline seems to work (baseline data files are created), Xcode seems to ignore that baseline altogether whenever the test is run. As a result, performance tests never fail, no matter how bad performance gets. The source editor persistently displays a “No baseline average for Time” message. Has anyone else encountered this? Figured out how to sidestep the issue? Of note, the issue is easily reproduced: create a new (macOS in my case) app project with tests, add a dummy performance test; run the test once and save its baseline, and despite this subsequent tests will always succeed, even if you significantly slow the dummy test down. (I've filed this as FB13330139)

Xcode Code coverage shows zero; even after 245 successful tests
I have a project inside the project structure. I have around 300 unit tests in the project. I see that for some of the subprojects, the coverage numbers show up correctly, but for other subprojects and the main project, the coverage number shows zero, even though the tests are running successfully. The log I get is: Aggregation tool emitted warnings: warning: /Users/ABC/Library/Developer/Xcode/DerivedData/projectABC-hfzmkbdgpiswoxfvvnvhrafaiqyb/Build/ProfileData/A8EEC1FB-1699-4C29-A88C-D3DDA226DBC0/0A416494-A393-4319-AA47-502D72084C9C-43351.profraw: raw profile version mismatch: Profile uses raw profile format version = 8; expected version = 10 PLEASE update this tool to the version in the raw profile, or regenerate the raw profile with the expected version. I only have one Xcode (26.0.1) on my machine. I tried cleaning the derived data, the cleaning project, and rerunning the tests, but it hasn't helped. Please help me get the coverage number back. Thank you.

XIB Files line seperator = none not be respected in iOS 26.1 ONLY
Hey All, Curious if you guys are seeing the same thing for those who are using Interface Builder Files (Xib) i set the line seperator to none and on my app (built against ios 18 on the app store, but doesnt matter if i build it against ios 26, or ios 26.1) when running on iOS 26.1 the line seperator will show even when i set it to None. Funny enough if i just play around with the XIB file and set it to single line and maybe RED color the IB file will show it but when running it its the same old default dark greyish color. BUT if i set the line seperator in CODE either to be none or with single line + red it looks good when running on sim / device. So it seems to be an issue with XIB files not being respected in iOS 26.1 (only) i have submitted a feed back FB20466783, hope this helps any xcode devs / uikit devs. thank you !

Issue in distributint my app on TestFlight.
Hi, yesterday when I was trying to release the TestFlight build of my app the xcode said that it could not authenticate my apple ID. I then came to know that it actually wanted me to complete and aggrement which was "Paid Apps Agreement". This agreeemnet is to be made if one has to sell their app on AppStore or make in-app-purchases. I want to ask if it was mandatory for me to sign that agreement? As the solution which I could come across suggested that xcode blocks the distribution if there is a pending agreement.

Existing Project Not Showing Installed iOS 26 Simulator (New Projects Work Fine)
Hello everyone, I'm encountering a frustrating issue with Xcode 26 and the iOS Simulator selection, and I'd appreciate any insight from the community. Problem Overview I have updated my Xcode to version 26.0. I have successfully installed the iOS 26 SDK and the iOS 26 Simulator runtime via Xcode's component settings. However, when I open an older, existing project, the device selection dropdown menu does not list the iOS 26 simulator. I can only select older versions, such as my locally installed iOS 18.6 simulator. Key Finding (Diagnosis) New Project Test: When I create a brand new Xcode project, the iOS 26 simulator is correctly available and runs as expected. Conclusion: This strongly suggests the issue lies with a specific configuration setting in the existing (old) project, rather than the Xcode installation itself. Troubleshooting Steps Taken I suspect a project-level configuration is somehow blocking the display of the new simulator. I've already checked: General -> Deployment Target: This is set to an older version, but theoretically shouldn't hide the simulator list. Build Settings -> Base SDK: This is set to the latest iOS SDK. Has anyone else experienced this behavior when upgrading projects to support iOS 26? What specific configuration files (e.g., .xcodeproj settings, Podfile configurations, or specific Build Settings) should I check to ensure my old project properly recognizes and displays the newly installed iOS 26 simulator? Any pointers or solutions would be greatly appreciated! Thank you.

Xcode 26 gets stuck frequently
Hi, Ever since I updated to macOS Tahoe and started using Xcode 26 daily, I've run into an issue where it gets stuck very frequently when launching and running my app in the simulator. It happens with the main app target as well as when running unit tests. If I restart Xcode and the simulator app, it works fine again for a while, but after some use, it goes back to the same situation. In Activity Monitor, Xcode ends up at 1000% CPU utilization for a minute or more, basically rendering the simulator and the debugger stuck. If I untick the "Debug Executable" option in the scheme editor, it works fine as well. Anyone else run into the same situation, or are there any tips I can follow to fix this issue? It makes it really tedious to make changes and then be stalled for a minute or more to see the app run. I've restarted the Mac, erased the booted simulator as well. I'm on a MacBook Pro M4 Pro. Everything used to run fine before macOS Tahoe / Xcode 26 on my main device. In fact, I used to run macOS Tahoe / Xcode 26 beta versions on a separate partition without any problems.

preferredImageDynamicRange is not marked as being available only for iOS 17 and above.
open var isAnimating: Bool { get } /// The preferred treatment to use for HDR images. By default the image view will defer to the value from its traitCollection. open var preferredImageDynamicRange: UIImage.DynamicRange /// The resolved treatment to use for HDR images. open var imageDynamicRange: UIImage.DynamicRange { get } This attribute is not marked as being applicable only in iOS 17+ versions. When viewing the UIImageView code in Xcode, the @available(iOS 17.0, *) annotation was not added, which resulted in successful compilation but caused a crash on iOS 16 devices.

Can't install iOS 26.0 beta through xcodes or xcodebuild
I need to automate updating to latest iOS betas as part of my ci script, but I can't get it to install iOS 26.0 beta for the life of me, using xcodes or xcodebuild. I can see the version listed using xcodes runtimes --include-betas, and I tried sudo xcodes runtimes install "iOS 26.0-beta1", but I would get the error Downloading Runtime iOS 26.0-beta1: 0% Error: ProcessExecutionError()\ I also tried xcodebuild -downloadPlatform iOS -buildVersion 23A5260l, where I found the specific build id on apples dev images website. But I would get the error iOS 23A5260l is not available for download. Specific version download failed, trying downloadPlatform ios latest... And similar error for trying xcodebuild -downloadPlatform iOS -buildVersion 26.0 or other version ids I found online. But this command would work for any other versions and betas listed on the website. I was able to install iOS 26.0 through xcodebuild -downloadPlatform iOS, which automatically installed it for me, but this is unideal for my situation, as I want to control which betas to install instead of just the latest one (like iOS 18.6 beta that just came out). Is anyone else also struggling with these errors? xcodes version 1.6.2 Xcode version 26.0 Beta (installed and selected through xcode)

UIStepper can't reach min/max value
When I build my project with Xcode 26 the following code makes the stepper decrement option disabled: stepper.stepValue = 0.5 stepper.value = 1.0 stepper.minimumValue = 0.7 stepper.maximumValue = 4.0 I think the reason for this is that the (value - stepValue) goes bellow the minimumValue. But on all iOS versions before iOS 26 this made the decrement option enabled and it clamped the value to the minimumValue. The same issue can be reproduced for the maximumValue. Does anyone else have the same issue? Do we need to adjust the stepValue based on the current value?

StoreKit Configuration Not Syncing to Xcode
Hello! I am attempting to add Subscriptions to an App that Is already published on the App Store. I cannot get Xcode to actually sync what is in my App Store Connect. When adding the Storekit configuration file, I go through the automatic linking process and select the proper bundleID. The configuration file says 'Synced @ [CurrentTime]' however there are no subscriptions listed in there. I have attempted deleting the file several times, creating a new subscription group. With no success. Do I need to publish the subscriptions without the features first? Upon attempting to write the supporting code that will enable these features within the app, I cannot get Xcode to identify that I have these subscriptions. I have also tried pushing these to TestFlight, still with no success. Thank you.

Unable to launch any simulators in Xcode, XPC error talking to liblaunch_sim.dylib could not be opened
Hello, been beating my head against the wall for a few days with this. Originally got the error in Xcode 16, through the course of troubleshooting uninstalled and reinstalled Xcode multiple times, upgraded Xcode to 23 - same result. Create a different user on my computer and try, same result. Xcode > Settings > Components show both iOS 26.0 and iOS18.6 simulator, however no simulators show in Xcode, and Xcode hangs when you try to create one. 'xcrun simctl list runtimes' shows this: iOS 18.6 (18.6 - 22G86) - com.apple.CoreSimulator.SimRuntime.iOS-18-6 (unavailable, liblaunch_sim.dylib could not be opened) iOS 26.0 (26.0 - 23A343) - com.apple.CoreSimulator.SimRuntime.iOS-26-0 (unavailable, liblaunch_sim.dylib could not be opened). Does anyone have any ideas on what the issue could be?

Environment description: macOS Catalina version 10.15.7 iOS Simulator version 12.3 Target device iPhone 11 (iOS 13.2.2) Open Safari > go to website > mictests.com Result: "Could not find any media devices. It is very likely that your browser does not allow access to these devices." The Simulator does have access to the microphone. I can use Siri just fine. Only Safari cannot access the mic. I'm really stuck here, any ideas are welcome.

Long loading time when showing/hiding the Code Review window in Xcode 26.0.1
When showing or hiding the Code Review window in Xcode 26.0.1, a loading screen appears and Xcode freezes. The loading screen appears for about 30 seconds, then disappears and the Code Review window appears. During this time, Xcode also freezes and cannot function. It doesn't seem to be an error or bug, but people who frequently switch between Code Review windows find the long loading time inconvenient. Is there any way to improve this? (MacBook Pro 16, M2 Max, 64GB memory, macOS 26.0 (25A354))

Xcode 26 Debug Error Display Issue
I recently installed Xcode 26.0.1. (MacBook Pro 16, M2 Max, 64GB memory, macOS 26.0 (25A354)) Normally, when debugging, a red error appears in the left-hand Issues navigation, and you can click on it to access the location of the error. However, currently, when debugging, the red error does not appear in the "Issue Navigation" on the left-hand side of the Xcode screen. There is an error, but it isn't displayed. It does appear, but disappears after 1 second. (It disappears before I can click on it.) The error doesn't appear or disappears after 1 second, so I can't pinpoint the exact location. Please help me resolve this issue. Additionally, I deleted all Xcode development-related files inside my Mac and restarted my MacBook, but the symptom still persists.

.tint() has no effect on macOS Liquid Glass toggles (on state background)
Environment: • macOS 26.0 (25A354) • Xcode 26.0.1 (17A400) Issue: Applying .tint(...) to a macOS Liquid Glass style Toggle does not change the background color when the toggle is in the on state. Expected behavior: The .tint(...) modifier should apply the chosen color. Actual behavior: The toggle remains system blue (accent color), regardless of the tint specified Notes: I’m hearing that .tint() behaves normally on iOS, so this may be macOS-specific.

Used Xcode AI to Clear 100+ Sendable Warnings
I have two apps in which I have fixed warnings on Sendable, however there's one app where I did not and it looks like the rent's come due with Xcode 26.0, as I am getting over 100 warnings about Sendable. On a lark, I let the AI work on the warnings. There were so many that I ran out of free ChatGPT time and had to wait 24 hours. But today I cleared every remaining warning, but did the app still work? I figured I'd have to trash this code and do it by hand. But to my surprise, the app is working properly so far. More testing needs to be done and I need to dig into the code to make sure it's right, but so far, so good.

xcodebuild failing when package plugin is added to project
I have created a build tool plugin in one of my SPM packages, and am trying to get it working in my project. It works fine when I build from Xcode, or have at least built the project in Xcode once before with the plugin. But if I try to build the project using xcodebuild on a machine where I have never built the project before, it fails with this error: error: '2.3.0': Invalid manifest (compiled with: ["/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc", "-vfsoverlay", "/var/folders/5_/q4yl04gs2kld1zztqxkqjdgh0000gq/T/TemporaryDirectory.BWwJWG/vfs.yaml", "-L", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/pm/ManifestAPI", "-lPackageDescription", "-Xlinker", "-rpath", "-Xlinker", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/pm/ManifestAPI", "-target", "arm64-apple-macosx14.0", "-sdk", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.5.sdk", "-F", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Frameworks", "-F", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks", "-I", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/usr/lib", "-L", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/usr/lib", "-swift-version", "5", "-I", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/pm/ManifestAPI", "-sdk", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.5.sdk", "-package-description-version", "5.7.0", "/private/var/folders/5_/q4yl04gs2kld1zztqxkqjdgh0000gq/T/SwiftTemplate/1FA05B4D-851D-4D2B-ADD6-E5A0DF70CD37/2.3.0/Package.swift", "-o", "/var/folders/5_/q4yl04gs2kld1zztqxkqjdgh0000gq/T/TemporaryDirectory.HUxmAq/2.3.0-manifest"]) <unknown>:0: error: error opening '/var/folders/5_/q4yl04gs2kld1zztqxkqjdgh0000gq/C/clang/ModuleCache/PackageDescription-3TZGMDBKTLI5E.swiftmodule' for output: /var/folders/5_/q4yl04gs2kld1zztqxkqjdgh0000gq/C/clang/ModuleCache/PackageDescription-3TZGMDBKTLI5E.swiftmodule: Operation not permitted /private/var/folders/5_/q4yl04gs2kld1zztqxkqjdgh0000gq/T/SwiftTemplate/1FA05B4D-851D-4D2B-ADD6-E5A0DF70CD37/2.3.0/Package.swift:4:8: error: failed to build module 'PackageDescription' for importation due to the errors above; the textual interface may be broken by project issues or a compiler bug 2 | // The swift-tools-version declares the minimum version of Swift required to build this package. 3 | 4 | import PackageDescription | `- error: failed to build module 'PackageDescription' for importation due to the errors above; the textual interface may be broken by project issues or a compiler bug 5 | 6 | let package = Package( On a machine where this isn't working, if I open Xcode and build the project once, then xcodebuild will succeed.

Is it possible that the sandbox being applied to the plugin is also being incorrectly applied to something involved in parsing and caching the manifest file? Or if there is something I am doing wrong, please let me know. This is using Xcode 16.4 on macOS 15.5.
