❗ Build Issues on Version 2.9.0 (iOS & Android)

Hi, I'm also encountering build issues after upgrading to pdfx: 2.9.0. These errors occur on both iOS and Android platforms.

📱 iOS Build Error Output

Running pod install...                                             17.9s
Running Xcode build...
Xcode build done.                                                  29.9s
Failed to build iOS app

Swift Compiler Error (Xcode): Type of expression is ambiguous without a type annotation

Swift Compiler Error (Xcode): Cannot find type 'NSColor' in scope
→ /Users/XXXX/.pub-cache/hosted/pub.dev/pdfx-2.9.0/ios/Classes/Hooks.swift:2:10

Swift Compiler Error (Xcode): No exact matches in call to initializer
→ /Users/XXXX/.pub-cache/hosted/pub.dev/pdfx-2.9.0/ios/Classes/SwiftPdfxPlugin.swift:367:34

Uncategorized (Xcode): Command SwiftCompile failed with a nonzero exit code
Encountered error while building for device.

⚠️ Cause:

This appears to be caused by the inclusion of NSColor in Hooks.swift, which is macOS-only. Since NSColor isn’t available on iOS (UIKit uses UIColor), Xcode throws an error during compilation.

BUILD FAILED in 12s
Running Gradle task 'bundleRelease'...                             13.2s
Gradle task bundleRelease failed with exit code 1

⚠️ Cause:

The Messages.kt file seems to be missing a required argument (forPrint) in one of its function calls. This results in a Kotlin compilation failure during the Android build.

---

🛠️ Temporary Workaround

• I’ve reverted back to pdfx: 2.8.0, which builds correctly on both platforms.
• For iOS, wrapping NSColor logic in a platform check (#if os(macOS)) could resolve the Swift compile error.
• For Android, the Kotlin function call needs to be updated to pass the missing forPrint parameter.

📌 Summary

Version 2.9.0 of the pdfx package introduces breaking changes that prevent building for both iOS and Android. I recommend holding off on using 2.9.0 until these issues are resolved.
