Xamarin Forms iOS集成Firebase推送后出现错误90-713及90-546的技术求助

Hi everyone,

I've been maintaining a Xamarin.Forms app that's been stable for 3 years. After a recent redesign, it's been live on the App Store for 2 months. This week, I integrated Firebase push notifications into the app—everything works perfectly on Android, but I'm hitting a roadblock with iOS.

First, I ran into error 90-713, which I managed to fix after 5 days thanks to a community member's solution. Now, though, I'm stuck on error 90-546, and none of the troubleshooting steps I've tried have resolved it.

My Development Environment #

• Windows-based Visual Studio 2019 16.10.0 (latest version at the time)
• Project structure follows VS2019 Solution Explorer standards
• Physical Assets folder contains all required icons

Info.plist Configuration #

Here's the relevant section of my Info.plist:

<key>CFBundleShortVersionString</key>
<string>23</string>
<key>CFBundleIcons</key>
<dict>
<key>CFBundlePrimaryIcon</key>
<dict>
<key>CFBundleIconName</key>
<string>AppIcons</string>
<key>CFBundleIconFiles</key>
<array>
<string>Icon-76.png</string>
<string>Icon-App-76x76@1x.png</string>
<string>Icon-App-76x76@2x.png</string>
<string>Icon-App-60x60@2x.png</string>
<string>167.png</string>
<string>152.png</string>
<string>120.png</string>
<string>Default</string>
<string>Default@2x</string>
<string>Default-568h@2x</string>
<string>Default-Portrait</string>
<string>Default-Portrait@2x</string>
</array>
</dict>
</dict>
<key>XSAppIconAssets</key>
<string>Assets.xcassets/AppIcons.appiconset</string>
<key>XSLaunchImageAssets</key>
<string>Assets.xcassets/LaunchImage.launchimage</string>

Steps I've Already Tried #

• Both keeping and removing the <key>XSLaunchImageAssets</key> entry and its value in Info.plist
• Creating a VS2019 for Mac project and a native Xcode project on a Mac to compare Info.plist configurations against my project

I'm really stuck here and would appreciate any technical guidance or insights you can offer.
