Ok, here is the snippet. import SwiftUI struct ContentView: View { @State var str: String = "Drag me" var body: some View { VStack(spacing: 100) { Text(str) .frame(width: 100, height: 100) .background(.blue) .onDrag { NSItemProvider(object: String(str) as NSString) } VStack { Text("Drop Here!") } .frame(width: 200, height: 200) .background(.red) .onDrop(of: [.text], delegate: MyDelegate()) } } } struct MyDelegate: DropDelegate { func performDrop(info: DropInfo) -> Bool { return true } } #Preview { ContentView() }

I've reported this issue on FB and this issue will be fixed in 18.1!

Hi, My Xcode is 16.3.1 (beta) and simulator is 18.4 (beta) but xcframeworks break again. But interest things are GMS* which is related with google maps.

Hi, I filed a feedback. The number is FB16747894.

Any updates?

As you said, GoogleMaps.a is not a static library when I check it with lipo -info GoogleMaps.a the result is Architectures in the fat file: GoogleMaps.a are: x86_64 arm64 And I'm using GoogleMaps v8.3.0 as the package's dependency and it produces a same result when I change it to v9.3. But it works when I make a new project and only add GoogleMaps with dependencies not package's dependencies and both results are the universal object GoogleMaps.a not the static library. FYI, I found GoogleMapsTarget.o which is static library in the same directory where the GoogleMaps.a is. Finally when I change GoogleMaps.a to .o Xcode regenerates GoogleMaps.a and produces results == PREVIEW UPDATE ERROR: FailedToLaunchAppError: Failed to launch previews.com.apple.PreviewAgent.iOS ================================== | [Remote] JITError | | ================================== | | | [Remote] CouldNotLoadInputStaticArchiveFile: Could not load static archive during preview: /Users/***/Library/Developer/Xcode/DerivedData/BOA-eiluspltxasszsfkpqrnnsxsjhth/Build/Products/Debug_BOA_Inhouse-iphonesimulator/PackageFrameworks/GoogleMaps.a | |

No it's private package. In our package, We have several 3rd party maps and these maps are compiled with the predefined settings in Xcode and the google map is one of them. Due to security reasons, we cannot share the internal structure. However, when Google Maps is required, it is added as a target in the project, as shown below. static var google = PackageDescription.Package.Dependency.package( url: "https://github.com/googlemaps/ios-maps-sdk.git", from: "8.4.0" ) ... ... ... static var google: [PackageDescription.Target] = [ .target( name: .google, dependencies: [ .byName(name: .core), .product(name: "GoogleMaps", package: "ios-maps-sdk"), .product(name: "GoogleMapsBase", package: "ios-maps-sdk"), .product(name: "GoogleMapsCore", package: "ios-maps-sdk") ], resources: [ .copy("Theme/dark.json") ] ) ]

Ok, sounds good! I'm waiting and please tell me if you need more information.

@Frameworks Engineer Is there any news for this subject? I'm looking forward to see the fix in new Xcode beta release.

This issue has been resolved on Xcode 26. Thank you!

As I mentioned, within the same package, preview works for a file in one target, but a file in another target throws the error mentioned above. It seems like a memory violation issue, but it's been difficult to find a reliable way to reproduce it. We'd like to share our code, but due to security constraints, that's not easy. We're looking for an alternative way to reproduce the issue. Are there any plans to fix memory-related preview issues in Beta 5?

It works for me after relaunching Xcode 26 beta 5. I tried it in Settings -> Components.

Hi, For your information, in Xcode 26 beta 5, the crash report provides some interesting new information.
