Greetings! A project that worked perfectly fine in Xcode 12.5.1 and earlier doesn't archive anymore in Xcode 13 Beta 5. It fails with this error.

CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compiler (in target 'Vectornator' from project 'Vectornator')
<Build command>
error: input file '/PrivatePath/Other Sources/R.generated.swift' was modified during the build
error: input file '/PrivatePath/Other Sources/R.generated.swift' was modified during the build
Command CompileSwiftSources failed with a nonzero exit code

The project is an iOS app with a Catalyst version. iOS builds, runs and archives fine. Catalyst builds and runs fine, but fails to archive. Here's the build phase setup.

Does anyone have any idea what's going wrong?

I will retest with Xcode 13 RC tomorrow and update the issue.

The currently latest alpha release of R.swift (5.0.0.alpha.2) supports Swift 4.2 and Xcode 10.

However, there is a known build system issue. We want to fix this issue before releasing the official 5.0 version of R.swift.

If you can work around the build system issue, feel free to use the alpha version of 5.0, it works pretty much like R.swift 4.0, but for Swift 4.2. (See complete list of differences)

Issue: R.swift build step and the New Build System

When the new build system is used, with a standard R.swift build step, this build step is not run before the Compile Sources build step.

Because of this, the initial compilation will fail, because there's no R.generated.swift file, and references to the R struct in the rest of the source code are invalid.

While it's easy to "build twice" during development in Xcode, this is particularly a problem on CI servers, where the build will simply fail because of the missing R.generated.swift file.

Partial solution: Adding R.generated.swift as an output file

As a fix for the above issue, you can add R.generated.swift as an output file:

This will make sure the R.swift step has finished, before the Compile Sources step starts. However, with this output file, the step will only run once:

Issue: Build step with output file only runs once

When R.generated.swift is configured as the output file (and there are no input files), the R.swift build step will only run once. On subsequent incremental builds, the step is skipped. Because of this, new resources won't show up in the R struct.

It is sometimes possible to list the resource files used als input files for the build step, but not always.

For example, when adding a new image to the asset catalog, the new filename isn't known beforehand.

Workarounds

These are possible workarounds:

1. Use the Legacy Build System. This behaves like before, and the R.swift build step will always run.
2. Commit the R.generated.swift file. This means during development, you can "build twice" and commit the resulting up-to-date file to git.
3. Clean build when resources change. Configure the output file for the build step, and manually do a clean build whenever one of the resources are changed.

None of these workarounds are ideal, so we're still looking for a proper solution.

This is a first draft of skipping resource files.

Not Implemented, yet

At this moment, following features are not implemented.

• wildcard
• skipping all files in folder
• must not start with "/" (.gitignore ignores first slashes)
• negation ("!" symbol at the beginning of the line)

Sample skip file

Same as .gitignore file, developers should specify relative path from --rswiftignore file. (I don't think it should accept using "..")

# filter Colors.jpg
ResourceApp/Images/Colors.jpg
# filter GdyBkltter1911.ttf
ResourceApp/Fonts/GdyBkltter1911.ttf

Hi I have problem in using R.swift. I do every step of installing R.swift using Pods in Xcode 10 but I have this error and no R.generated.swift generated : [R.swift] The folder “R.generated.swift” doesn’t exist.

Can we add support to recognize the local files stored in the project? Sometimes we add videos, html or json files to the project directory. We should add capability to recognize those files as assets as well.

Happy to create a PR for this if someone can give me directions on how to implement.

I installed with CocoaPods.

Then i got warning [R.swift] File could not be parsed as Info Plist from URL: /path/to/project/module_name/ $(SRCROOT)/project_name/my_path/Info.plist on xcode 11.2.1.

However i can use R.swift methods.

Using version

• Xcode 11.2.1
• CocoaPods: 1.8.4
• R.swift (5.1.0)
• R.swift.Library (5.1.0)

Hello,

We are trying to get R.swift setup with our project and we are running into the following error when building the project.

Command /bin/sh failed with exit code 132

We installed R.swift via Cocoapods and added the following Run Script above Compile Sources and below Check Pods Manifest.

"$PODS_ROOT/R.swift/rswift" "$SRCROOT"

We were able to get R.swift to work in a newly created project.

We are using Xcode 8.3.3 and targeting iOS 9.0. The project is Objective-C and Swift 3.

Any help would be greatly appreciated! :)

I am using R.swift in my project. I some of my view controllers are of instances of GRKStoryboardProxyViewController.

I have upgraded to R.swift version 3.1.0 and now the R.generated.swift file doesn't import GRKStoryboardProxyViewController

I am getting "use of undeclared type" errors in

/// Optionally returns a typed version of segue `showCustomer`.
/// Returns nil if either the segue identifier, the source, destination, or segue types don't match.
/// For use inside `prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)`.
static func showCustomer(segue: UIKit.UIStoryboardSegue) -> Rswift.TypedStoryboardSegueInfo<UIKit.UIStoryboardSegue, BookingViewController, GRKStoryboardProxyViewController>? {
    return Rswift.TypedStoryboardSegueInfo(segueIdentifier: R.segue.bookingViewController.showCustomer, segue: segue)
}

and other parts of the file where GRKStoryboardProxyViewController is referenced

I am sorry in I have done some thing wrong and this is not an issue, but any help would be greatly appreciated

Hi,

Using the new build system (the default setting) with Xcode 10 Beta 6 results in the first build failing. Subsequent builds pass.

Configuration

• Xcode 10 Beta 6
• R.swift added via cocoapods
• R.swift build script as follows $PODS_ROOT/R.swift/rswift" "generate" "$SRCROOT

Result error: Build input file cannot be found: '/Project/R.generated.swift'

On a local machine, this is not a problem, as we can build again. However, on a CI environment such as Buddybuild, the build continuously fails as it performs a clean build every time.

I would like to use localized strings in addition to NSLocale.currentLocale().

Pattern 1:

struct string {
  struct localizable {
    let locale: NSLocale
    init(locale: NSLocale = NSLocale.currentLocale()) {
      self.locale = locale
    }
    /// Locales: en, ja
    static func helloWorld() -> String {
        return String(format: NSLocalizedString("HelloWorld", comment: ""), locale: self.locale)
    }
  }
}

Pattern 2:

struct string {
  struct en {
    /// Locales: en, ja
    static func helloWorld() -> String {
        return String(format: NSLocalizedString("HelloWorld", comment: ""), locale: NSLocale(localeIdentifier: "en"))
    }
  }
}

Hi!

I was using R.swift 5.0.0-alpha2 and had a unit test running validate() which was correctly failing whenever I had a wrong asset or font in a XIB:

XCTAssertNoThrow(try R.validate())

I've just updated to 5.0.0 and checked if that was still working before merging this update, but the test now passes for the same incorrect asset/font that fails the test at 5.0.0-alpha2.

Am I doing this in a deprecated way or is the feature broken?

Thanks!

Env: macOS Monterey 12.6 Github Actions Virtual machine Xcode 14.2 R.swift 7.2.4 (SPM install)

The error log is as follows

sandbox-exec: execvp() of '//Users/runner/Library/Developer/Xcode/DerivedData/RSwiftCI-ebevhdqipdqdlhcxuuhqrvdkfehb/Build/Products/Debug/rswift' failed: No such file or directory
Command PhaseScriptExecution failed with a nonzero exit code

I was using version 6.x in the project before and it was installed using mint, everything was working as expected in CI also. Today I migrated to version 7.4.2 using SPM, the project builds locally but fails on CI.

I have created a public repository to reproduce the issue and share logs Link to the above CI run - https://github.com/abin0992/RSwiftCI/actions/runs/3848557429/jobs/6556494563

Xcode build command is xcodebuild -project 'RSwiftCI.xcodeproj' -scheme 'RSwiftCI' -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 14 Pro' -UseNewBuildSystem=YES -skipPackagePluginValidation

Everything works as expected when I build locally using the same command.

Kindly let me know if I am missing something in Xcode build command or configuring CI environment.

In my project, there is a folder with images that should be used only for working with the database, and in my code I do not explicitly refer to them (for example, R.image.closeIcon()). This directory is located inside asset and has the path: /Users/anatoliy/Documents/develop/work/ELEL/iOS/mobile-ios23/DMVGenius/Resources/Assets/AssetsDMV.xcassets/imagesUS

I attached a screenshot of what the asset structure looks like in Xcode and in Finder:

I added exceptions to the .rswiftignore file for such a folder so that R.swift objects are not generated for the image from this folder:

# **/AssetsDMV.xcassets/imagesUS/*

DMVGenius/Resources/Assets/AssetsDMV.xcassets/imagesUS

**/imagesUS/*

But that didn't work for me and I still get xcode warnings:

[R.swift] Skipping 974 images because no swift identifier can be generated for all of these images: '050520132206252694', '050520132211282376', '110320131739549584', '110320131744509927', '140320131714351981', '1573301280',

Any ideas how to get the exception to work and not throw errors for a particular directory (imagesUS)?

P.S. The remaining folders with images and icons inside this assets are used by me explicitly in the project code.

This is what I wrote in the pod spec file:

s.dependency 'R.swift'

s.script_phases = [{ :name => 'R', :script => '"$PODS_ROOT/R.swift/rswift" generate --access-level public "$SRCROOT/FolderName/R.generated.swift"', :execution_position => :before_compile, :input_files => ["$TEMP_DIR/rswift-lastrun"], :output_files => ["$SRCROOT/FolderName/R.generated.swift"] }]

And this is what the R.generated.swift file produces:

private class BundleFinder {} let R = _R(bundle: Bundle(for: BundleFinder.self))

struct _R { let bundle: Foundation.Bundle func validate() throws {

}

struct project { let developmentRegion = "en" } }

The R.swift version is : 7.1.0

Hi there,

We recently migrated to V7, and it works perfectly, in our local machine and CircleCI.

The issue now is with Xcode Cloud, as we are getting this error from logs.

PhaseScriptExecution R.swift\ generate\ resources\ for\ application\ APPLICATION_NAME/Volumes/workspace/DerivedData/Build/Intermediates.noindex/APPLICATION_NAME.build/Debug-iphonesimulator/APPLICATION_NAME.build/Script-72183A77293DDBE600A947EF.sh (in target 'APPLICATION_NAME' from project 'APPLICATION_NAME')

Error: You don’t have permission to save the file “R.generated.swift” in the folder "Resources".
LLVM Profile Error: Failed to write file "default.profraw": Operation not permitted

Looks like the build script doesn't have access to Resources folder in Xcode cloud 🤔 We've done everything as the migration guideline suggested.

Do you have any suggestion? 🤔

Thanks!
