hy! apple developer community! No, I have a problem that's driving me crazy: Multiple commands produce '/Users/giulia/Library/Developer/Xcode/DerivedData/ScheduledStudy-dcmmhcdncitvfkdditbjoipfalqg/Build/Products/Debug-iphonesimulator/singintestwidgetExtension.appex/Info.plist'. Can you help me fix it? I know it's probably stupid, but I've been trying to fix it for days. There aren't two info.plist file, and that's why I don't quite understand. If you could help me, you'd be doing me a favor. Thanks for your time.
P.S. I'm sorry, but I'm just starting out with programming and I'm also quite young.

Ever since updating to Xcode 16.3, auto-completing variable names in lldb does not work.
Is this a known bug? Is there a workaround to get it do auto-complete again?
I'm trying to create a preview for my live activities when it's stale, so I created a preview provider. I followed some examples, but XCode says I'm missing preview context. Am I doing something wrong?
I tried adding .previewContext(WidgetPreviewContext(family: .systemSmall)) but that doesn't seem to work.
Hi Apple Developer Community. I have a problem with opening my Xcode File in Xcode 16. It says, that a specific File is missing and I don't know how to resolve this. Can someone help me?
Thanks for the help :)
Hello,
Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices.
Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations?
TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.
This is the Icon Composer from Xcode 26.0 Beta 1 (not the really old one Xcode6? 😆 that I find when I search here)
Is there a way to show the really cool 3D that they showed off during demos? Maybe all we get is which level is on top.
Upon export it only seems to be able to do 2x? - is there some way to get it to take 1x? Every time I change it - it jumps back to 2x and iOS wants 1x... maybe a feedback.
Also Xcode seems to want 3 icons - but there are 6 iOS ones exported. How do I get the other 3 in there?
It does seem pretty easy to import PNG's from Sketch and order them and move pieces around. I guess you can save individual lighting for each icon mode.

Canvas Previews (targeting macOS) in both Xcode 16.4 & Xcode 26 fail to load, when the project imports a Swift package that imports and uses WebKit.
I'm on macOS 15.5.
Tried also to bring minimum targets of both the project and the package to 15.0.
I see that there are some work-arounds for iOS simulator but nothing for the Mac.
Anyone facing the same problem?
Hi,
I am in the last step "preparing for submission" and everything excepts "age rating" is fine. How can I fix this?
I have two apps and on neither i can edit "age rating" :(
Anyone else notice that Xcode 16.1 seems to have stopped building universal binaries for both debug and release builds even though under "Build Settings-Build Active Architecture" both Debug and Release are set to NO. We had been using the universal binary builds out of Debug for preliminary tests on Intel based machines. The Architectures setting is set to: Standard Architectures (Apple Silicon, Intel) - $(ARCHS_STANDARD).
I started a brand new empty app and it does the same thing.
A workaround is to set the Destination in Xcode's menu bar to "Build on Any Mac" and then find the binary and drag it to the Intel computer. You can't run that one though from Xcode. Another workaround is to build an Archive and drag that one.
I am trying to run Xcode 15 on macOS 15.4.
As we need to build framework with older versions of Xcode.
Any work around for it?
I have a sample SwiftUI iOS app. As shown in the screenshot below, my project has three configurations: Debug, MyDebug, Release.
If I select the Debug or MyDebug scheme, I get a preview. But if I select the Release scheme, I get an error that says the following.
”***.app” needs -Onone Swift optimization level to use previews (current setting is -O)
, where *** is the app name.
It probably has nothing to do with the Preview error, but the Info.plist has a dictionary such that the key name is devMode, and the value is $(DEVMODE). And I have a user-defined setting as shown below.
My ContentView has the following.
import SwiftUI
struct ContentView: View {
@State private var state: String = ""
var body: some View {
VStack {
Text("Hello, world!: \(state)")
}
.onAppear {
if let devMode = Bundle.main.object(forInfoDictionaryKey: "devMode") as? String {
print("Development mode: \(devMode)")
state = devMode
}
if let path = Bundle.main.path(forResource: "Info", ofType: "plist") {
if let dict = NSDictionary(contentsOfFile: path) {
print("**** \(dict)")
}
}
#if DEBUG
print("Debug")
#elseif MYDEBUG
print("MyDebug")
#else
print("Que?")
#endif
}
}
}
#Preview {
ContentView()
}
So my question is how I get the preview for all three build schemes? Muchos thankos.
Is anyone else having trouble with the Documentation in the latest Xcode beta? I can't get any UIKit documentation to appear. UIKit is completely missing from the table of contents too. I've tried deleting the documentation caches but it isn't helping.

I'm trying to bring up an existing macOS app workspace to build against the macOS 26 SDK, however Xcode 26b1 is producing the following error, and I'm unable to proceed:
/Users/tonyarnold/Documents/Reveal/<unknown>:1:1: error reading '/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/include/module.modulemap': No such file or directory
/Users/tonyarnold/Documents/Reveal/<unknown>:1:1: failed to emit precompiled module '/Users/tonyarnold/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/_Builtin_stdbool-LVR359SH1U4537HG9T3JOGN.pcm' for module map '/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/include/module.modulemap'
I've checked and the module map that it claims is missing is there on the filesystem.
Is this a known issue with this beta?

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

Hi
I've downloaded the latest version of Xcode 14.2 but when I run the app in Simulator I can only test it on iOS16.2 Is there a way to run it in 16.3?
I've created a new project in Xcode. I'm running the Xcode 16.4 and MacOS 15.5.
I'm trying to run my barebones project on my iPhone 16 (I'm just getting started). I turned on developer mode on my iPhone and went through the whole process. But in the Signing & Capabilities of my project under status I see two errors...
There is a problem with the request entity
A device with number 'XXXX8801C' already exists on this team.
Provisioning profile "iOS Team Provisioning Profile: [MyBundleID]" doesn't include the currently selected device "My iPhone" (identifier XXXX8801C).
I noticed in the devices on the developer portal that my device is showing as "Processing." I feel ike it's stuck. But I can't figure out how to clear it all out and try again. It's been 24 hours since this error came up.
I've tried to clear trusted computers on the iPhone. I've deleted the "Derived Data" folder. I've removed my developer account from Xcode and added it again. I've restarted both my Mac and my iPhone multiple times.
I've noticed it asked to authorize my computer twice. When I clear the authorized computers and then plug the phone back in it asks twice again. So I'm not sure if this is the issue? No idea why it asks twice but I'm only ever able to respond to the second request as the first request gets blocked in the UI by the second requests if that makes sense?
I'm also not able to turn off developer mode on my iPhone. The switch isn't there as the docs state it should be. So again, I feel like this is the phone and the developer portal stuck causing the problem.
Note: I saw someone else had encountered this problem and I replied to it and boosted it. But it looks like it was posted in 2017? Hence this new post.

I am having similar problems to this guy on Stack Overflow over a year ago:
https://stackoverflow.com/questions/77627852/functions-of-iouserscsiperipheraldevicetype00-class-in-scsiperipheralsdriverkit
There are also a few questions on this forum about this object, none of which have answers.
I can get my driver to match and instantiate, but
nobody calls my UserDetermineDeviceCharacteristics (which does nothing, just returns kIOReturnSuccess)
I can attempt to call UserSuspendServices(), UserResumeServices() or UserReportMediumBlockSize() and all of them return kIOReturnUnsupported. It doesn't matter if I've unmounted the disk or not.
Is the custom driver supposed to be instantiated beside the kernel's IOSCSIPeripheralDeviceType00, or should it replace it?
What should its IOProviderClass be?
What should its IOClass be - IOUserService, or something else?
see FB19678139 and FB19677920

Hi! I´m new developing in this app, I have a problem.
The preview screen is showing me the image bellow, There is no other response, I dont know what could happened.
Thanks!
I use Carthage to build a set of dependencies. I generate .xcframework files with code for both macOS and iOS. This works through Xcode 26 beta 4. With Xcode 26 beta 5, the resulting .xcframework files seem to have code only for iOS, not macOS. Each framework has a ios-arm64 directory and a ios-arm64_x86_64-simulator directory, but no macos-arm64_x86_64 directory.
This is affecting 3 of my 7 cross-platform dependencies that I compile with Carthage. What those 3 seem to have in common is that each has one target and scheme for the shared library – instead of one for iOS and another for macOS.
I may have to create a second scheme and target in each of these dependencies, or move to SPM. But I am wondering if anyone has another suggestion.
Thank you.
John
