[iOS] "Could not find a part of the path" Firebase CloudMessaging

[k4p1cz]

Description

Hello.

I have a problem that I've been strugling with.
I want to test Firebase notifications for my iOS project so I've created a new one to test it on.
I've added Xamarin.Firebase.iOS.Core and Xamarin.Firebase.iOS.CloudMessaging as well as GoogleService-Info.plist and Entitlements.plist.
I've edited the AppDelegate.cs accordingly. When I try to build it, it builds with no issues but when I try to deploy the app to my local device I get a deploy error.

The log from Xamarin\Logs\17.0 is listed in "Relevant log output" but the error is:
"An error occurred while trying to create the .ipa file for TestIOS2. Details: Could not find a part of the path 'C:\Users\FantasyCZE\AppData\Local\Temp\Xamarin\HotRestart\Signing\TestIOS2.app\out\Payload\TestIOS2.app\TestIOS2.content\Firebase.CloudMessaging.resources\FirebaseMessaging.xcframework\ios-arm64\FirebaseMessaging.framework\Headers\FIRMessagingExtensionHelper.h'."

If you need anything that will help you, let me know.
I'm new in .NET MAUI.

Thank you!

Assuming you're using VS for Windows, this is the "max path" error. Enabling long paths in Windows won't help; VS ignores that setting.
This problem has been known for years and may never be fixed. Your options are to:

• Shorten your paths down to be VERY short, as in one or two characters. This includes your NuGet package cache folders, the folder(s) that contain your project, and the overall folder that contains all of your projects/source code. Shortening the NuGet package path is probably best done by using a nuget.config file.
• Do NuGet restores and builds only from the command line. This is after enabling long paths in the Windows registry.
• Only restore/build on a Mac. This is a Windows-only problem.
• Use what used to be known as "slim bindings." Firebase is one of the examples here. The trend is to have us manage our own bindings rather than centralize it (although some bindings will be maintained such as AndroidX, etc.)

In short, this is not a MAUI problem, and not even a .NET for iOS problem (specifically). It's a Visual Studio on Windows problem.

@brunck Thank you. I'll try that. But where can I find nuget.config file?

@brunck Thank you. I'll try that. But where can I find nuget.config file?

You create it yourself. Search the documentation; it’ll have more information.

I don't think this is the MaxPath issue. From the logs I can tell you are using Hot Restart and as part of the limitations you cannot use xcframework resources.

If you want to use this, you will have to deploy through Mac hardware.

Closing this here as there is nothing we can do about this currently.
