“Xcode”

Hello! I'm new to xcode and am developing an iOS app. I hit the following error when build my app: MY_SHA no identity found Command CodeSign failed with a nonzero exit code I have generated my certificate through xcode. I can see the Certificate and the private key in Keychain -> login. But it's not that private key is under the Certificate. They are listed in parallel. The certificate appears in Certificate tab but not in My Certificate Tab. Would that matter? security find-certificate -a -Z | grep -A1 Apple Development Gives me the certificate. But security find-identity -v -p codesigning give 0 valid identity found. Could you help me figure out what could be the reason for this? I've been stuck for several days now. Thank you so much!

Objective: Downloading and running an old Swift iOS App on iPhone 5s with iOS 12.5.8. Development System and Tools: Apple macBook, M4 Pro, running macOS Tahoe 26.3.1 (25D2128). Xcode Version 26.3 (17C529)

I am unable to use my iPhone 17 Pro as a run destination in Xcode. The device appears at a low level, but CoreDevice / devicectl keeps reporting it as unavailable. Environment • Mac mini (Apple Silicon) • macOS 26.3 (Build 25D125) • iPhone 17 Pro • iOS 26.3 • Xcode 26.3 (Build 17C529) • Xcode 26.4 beta 2 (Build 17E5170d) Symptoms • The iPhone appears in Finder • On the iPhone, I tapped “Trust This Computer” • Developer Mode is enabled • Apple ID is added in Xcode Accounts • Team is configured in Signing & Capabilities • iOS Platform Support is installed • The device still does not become available as a run destination • Devices and Simulators does not show it in a usable state • xcrun devicectl list devices still shows unavailable Output of xcrun devicectl list devices Failed to load provisioning paramter list due to error: Error Domain=com.apple.dt.CoreDeviceError Code=1002 No provider was found. UserInfo={NSLocalizedDescription=No provider was found.}. devicectl manag

DeviceActivityReportExtension sandbox blocks all output channels — how to export resolved Application.bundleIdentifier? Application.bundleIdentifier only resolves to a non-nil value inside a DeviceActivityReportExtension (ExtensionKit/XPC). The main app and DeviceActivityMonitor extension always return nil. However, the Report Extension's sandbox silently blocks every output channel I've tested: UserDefaults (App Group): Reads succeed, writes silently dropped File writes (App Group container): Fail silently or throw HTTP requests: Network blocked entirely Local Notifications: Couldn't communicate with a helper application UIPasteboard: Writes silently fail iCloud KVS: synchronize() returns false Both targets share the same com.apple.security.application-groups entitlement and group identifier. The main app reads and writes to the shared container normally — only the extension's writes fail. This means resolved bundle identifiers can only be rendered in the extension's own SwiftUI view and cannot be communicat

iOS 15 - iOS 26.x, SwiftUI, Xcode 26.1.1 (rewritten without links) I’m attempting to add the capability to export a file from CoreData. Since ShareLink requires iOS16+, I found an article showing how to create a UIKit wrapper for 'UIActivityViewController' This does work, but I end up with multiple files instead of one. How do I merge this into one file? Note: I don’t think I want to write to the app’s document directory – rather I’d like to allow the user to export to iCloud. Eventually, I’d like to share a list of dates with descriptions and if someone puts a sensitive date in there – I don’t want it to be left in a directory. I would include a warning that the file that they export needs to be handled with care if there are any sensitive dates. Some might consider birthdays as private information, right? I'd also like to be able to name the file - so far when the share sheet comes up, I select Save to Files and it uses a default name of text.txt My next step is to be able to import a CSV file (rou

I tried to build my project with -fsanitize=fuzzer. This failed to link with libclang_rt.fuzzer_osx.a not found when attempting to link the code. I mean really!! Why on earth would you exclude this from the version of clang that ships with XCode!

I'm trying to download the iOS 26.2 simulator, but it fails both in Xcode and via the command line. When I run: xcodebuild -downloadPlatform iOS -buildVersion 26.2 -exportPath ~/Downloads It returns: iOS 26.2 is not available for download. I would like to know: Why iOS 26.2 simulator cannot be downloaded at the moment. Whether iOS 26.2 simulator is still available, or if it has been removed or replaced. How to properly get and install the iOS 26.2 simulator. Any official explanation or solution would be greatly appreciated. Thank you!
