I found a problem with the latest Xcode 13.2/13.2.1 when compiling SwiftUI if-#available structure. When building with Release mode, the app always crashes on an older system. import SwiftUI struct ContentView: View {   var body: some View {     List {       if #available(iOS 15.0, *) {         Text("Hello").badge(1)       } else {         Text("Hello") // 💥 always crash: iOS 14 + release mode       }     }   } } Sample crash log: OS Version: iPhone OS 14.8.1 (18H107) Release Type: User Baseband Version: n/a Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000000 VM Region Info: 0 is not in any region.

Hello, In Xcode 15 beta 3, if a project embedded a Swift package (no matter static or dynamic), and the package has its own dependencies, the linker will always emit following warning: ld: warning: duplicate -rpath '/Users/.../Library/Developer/Xcode/DerivedData/MyApp.../Build/Products/Debug-iphonesimulator/PackageFrameworks' ignored The warning is not appeared on beta 2 and beta 1. Reproduce Steps [1] Create a new iOS project in Xcode 15 beta 3 [2] Create a new Swift package MyLibrary, and add any dependency in the Package.swift. Example: // swift-tools-version: 5.9 import PackageDescription let package = Package( name: "MyLibrary", platforms: [.iOS(.v16)], products: [ .library(name: "MyLibrary", targets: ["MyLibrary"]), ], dependencies: [ // 👀 Add any dependency to this package. // Here I use "Version" which is a simple pure swift package: .package(url: "https://github.com/mxcl/Version.git", .upToNextMajor(from: "2.0.0")), ], targets: [ .target(name: "MyLibrary", dependencies: ["Version",]), ] ) [3] In the project page, embed MyLibrary into the iOS app target. [4] Build the project. It will succeed but with link warnings. In addition, if you create a dynamic framework and embed MyLibrary, the warnings also reproduce. And this is only a simple case. In my real project, the linker will also emit a lot of warnings like this: ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$__TtP10SPConfetti18SPConfettiDelegate_ ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$__TtP10SPConfetti18SPConfettiDelegate_ ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionTaskDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDataDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDownloadDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSObject ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionTaskDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDataDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDownloadDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSObject

In Xcode 15 beta 6, building any Mac Catalyst project will encounter the following Linker warning. ld: warning: building for 'macCatalyst', but linking in dylib (/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa.tbd) built for 'macOS'

Hello :) My iOS project does not work with SwiftUI Preview in Xcode 14 beta. The project builds and runs fine, but Preview never works. The error message is as follows. HumanReadableSwiftError SettingsError: noExecutablePath(&lt;IDESwiftPackageStaticLibraryProductBuildable:ObjectIdentifier(0x000060002ac3e880):'AppCenterCrashes'&gt;) I do use the AppCenterCrashes dependency in my project. But I'm not sure if this error message is accurate, because sometimes it reports other packages. After I executed Generate Report, I found the following error in SerializationErrors.txt. Error Domain=NSCocoaErrorDomain Code=516 "“LogCaffeineIntent.swift” couldn’t be linked to “Intermediates” because an item with the same name already exists." UserInfo={NSSourceFilePathErrorKey=/Users/gong/Library/Developer/Xcode/DerivedData/.../Build/Intermediates.noindex/HiCoffee.build/Debug-iphonesimulator/IntentsExtension.build/DerivedSources/IntentDefinitionGenerated/Intents/LogCaffeineIntent.swift, NSUserStringVariant=( Link ), NSDestinationFilePath=/var/folders/lv/58r5dhv52j779_qn41gnq4c80000gn/T/previews-diagnostics-20220608-144336/Intermediates/LogCaffeineIntent.swift, NSFilePath=/Users/gong/Library/Developer/Xcode/DerivedData/.../Build/Intermediates.noindex/HiCoffee.build/Debug-iphonesimulator/IntentsExtension.build/DerivedSources/IntentDefinitionGenerated/Intents/LogCaffeineIntent.swift, NSUnderlyingError=0x600033223810 {Error Domain=NSPOSIXErrorDomain Code=17 "File exists"}} The problem seems to be related to the Intent generation code. I don't know how to fix it yet.
