Hi, we recently starting moving toSwiftUI and unable to preview. we are getting a below crash. App is running using Rosetta on M1 Mac Xcode 14 iOS 16 All we did is to enable swift previews in build settings.

HI, I have an issue displaying SwiftUI previews with Xcode 14. My project has iOS and an watchOS Target. It also includes a lot of SPM, most of them only used by the PhoneApp. The project build successfully for both iOS and watchOS. I can see that when building the watch target, only SPM that are included in this target are build for for watchOS The issue is when I try to build a swiftUI preview of the watch target. In this case I can see on the build for Preview log that Xcode try to build ALL spm defined in the Xcode project, including the one that are not used by the watch Target, As a lot if spm are for iOS only, and doesn't build for watchOS, the build for preview fails, and I'm unable to preview my swiftUI views on the AppeWatch. Note that my project is working fine on Xcode 13. This issue is easy to reproduce in any Xcode projects containing a iOS and watchOS target by adding a SPM that is only for iOS. Any workaround to fix this issue ?

Failed to decode landmarksData.json from bundle because it appears to be invalid JSON. Full disclosure - Im extremely new to this and am playing around with the swift tutorials to see what it can do and see if I could build an app. Any advice is appreciated. I added a few locations to the SwiftUI Tutorial for Lanmarks and this is what happened. I have checked that JSON file and all commas are in the correct place everything is correct but im getting this error. Not sure what im doing incorrectly. Can anyone give me assistance on how to fix this. I can only preview favorite button, circle image and map. Everything else appears as Fatal Error in ModelData.

The the enhancements to Xcode Previews in Xcode 14 are very helpful. I just had a situation where I wanted to take a screen capture of a preview of a view. Is there a built-in way to do that from Xcode, similar to taking a screen capture of the simulator screen? I realize I can just use a system-level screen capture, but then I have to adjust the size of what I capture to the area of the view in the preview. It would be great to just be able to have a button or shortcut and have the correct area captured.

The Build for Previews builds all my targets including the test targets. Is there a way to configure the relevant targets? I do not see an option in the schema editor, and disabling Find Implicit Dependencies has no effect either.

SwiftUI Preview Don't work. Progress Preparing iPhone Simulator for Previews. SwiftUI Xcode version 13.0 macOS Big Sur version 11.6

I have an iOS app by using a swift package to hold most of the logic. However, the previews of SwiftUI views often fail with following error: HumanReadableSwiftError BuildError: failedToGenerateThunkInfo(Error Domain=com.apple.xcbuild Code=19 "could not generate preview info: noTargetBuildGraph" UserInfo={NSLocalizedDescription=could not generate preview info: noTargetBuildGraph}) To reproduce this, please clone https://github.com/pointfreeco/isowords and check for preview of ChangelogView.

Hi everyone, I'm trying to follow the Landmarks project tutorial and got stuck in the second part, in the second section (Create the Row View), step 6 where it says "Modify the text view to use the landmark property’s name." This must be done in the LandmarkRow.swift file. https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation The tutorial shows that after doing this, the preview will display the name of the landmark (Turtle Rock) instead of the usual "Hello world" greeting. But my replacement is not happening. Moreover, from this point on, the preview stops working. There are no error messages in the code, except for the message that the preview could not be performed. I checked and rewrote the code several times, replaced the data source files, but nothing helped. At the same time, the preview works well in other view files. I can't figure out what's wrong with my code? Any ideas as to what the reason will be is appreciated. Below is the code of two files, the LandmarkRow.swift, where view does not work, the second is ModelData.swift and it is related to the previous one. LandmarkRow.swift import SwiftUI struct LandmarkRow: View {     var landmark: Landmark     var body: some View {         HStack {             landmark.image                 .resizable()                 .frame(width: 50, height: 50)             Text(landmark.name)             Spacer()         }     } } struct LandmarkRow_Previews: PreviewProvider {     static var previews: some View {         LandmarkRow(landmark: landmarks[0])     } } ModelData.swift import Foundation var landmarks: [Landmark] = load("landmarkData.json") func loadT: Decodable(_ filename: String) - T {     let data: Data     guard let file = Bundle.main.url(forResource: filename, withExtension: nil)     else {         fatalError("Couldn't find \(filename) in main bundle")     }     do {         data = try Data(contentsOf: file)     } catch {         fatalError("Couldn't load \(filename) from main bundle:\n\(error)")     }     do {         let decoder = JSONDecoder()         return try decoder.decode(T.self, from: data)     } catch {         fatalError("Couldn't parse \(filename) as \(T.self):\n\(error)")     } }

Repro steps: Create new project Create WidgetKit extension (verify that previews work) Create dummy framework (verify that previews still work) Link dummy framework to the widget extension At that point, preview stops working with the following error: "RemoteHumanReadableError ProcessError: Failed to launch widget extension: The operation couldn’t be completed. (CHSErrorDomain error 1050.)" What can I do to make this work?

Any help with preview crash on an App that is building just fine and runs on simulator fine? Are there logs that I can access somehow? The previews were working just fine, but then stopped and I have reverted all changes since and the previews are still broken.

I have two (local) Swift packages (both with a single library product): RemoteImage, which defines setImage(from:) function on UIImageView and SatelitUI package which directly depends on the first one and defines some views. But when I'm trying to preview views from the second package I'm getting the following error: linker command failed with exit code 1 (use -v to see invocation) LinkDylibError: Failed to build TrailerView.swift Linking failed: linker command failed with exit code 1 (use -v to see invocation) ld: warning: directory not found for option '-F/Applications/Xcode-beta.app/Contents/SharedFrameworks-iphonesimulator' Undefined symbols for architecture x86_64:   "(extension in RemoteImage):__C.UIImageView.setImage(from: Foundation.URL?) -> ()", referenced from:       (extension in SatelitUI_PreviewReplacement_TrailerView_2):SatelitUI.TrailerView.(previewupdate in _8C3731B0EF007627509BEEB93277D681)(with: SatelitUI.Trailer?) -> () in TrailerView.2.preview-thunk.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) Apparently, Xcode fails to link the library from the first package because it's dynamic. Static linking works as expected. It's a bug I believe?

I keep getting a Xcode Previews error in Xcode 12 from a package that imports other packages. As soon as I remove the dependency I'm able to see the SwiftUI preview. I'm only able to use previews in packages that have no dependencies The error I get is: "LoadingError: failed to load library at path...Library not loaded " then it point to the dependency that it could not load in the current package. How can I access Xcode Previews from a package that depends on other packages?

I'm trying to preview a view from a swift package which is located in one of the target's directory subdirectories: . ├── Package.swift ├── README.md └── Sources 		└── SatelitUI 				└── Views 						└── MenuBar.swift When I'm previewing a view from the MenuBar.swift file I'm getting following error: NoBuildableEntriesError: active scheme does not build this file Select a scheme that builds a target which contains the current file, or add this file to a target that is built by the current scheme. Which is unexpected because the file should be a part of the SatelitUI target. The thing is it works just fine if I move it into the root target's directory (SatelitUI).
