I have updated the NuGet packages Microsoft.Maui.Controls, Microsoft.Maui.Controls.Compatibility and Microsoft.Maui.Essentials from version 8.0.61 to 8.0.70. Then I got the following error when I tried to build my iOS project:
Error MSB4019 The imported project "C:\Program Files\dotnet\packs\Aspire.Hosting.Sdk\8.0.2\Sdk\AutoImport.props" was not found. Confirm that the expression in the Import declaration "C:\Program Files\dotnet\packs\Aspire.Hosting.Sdk\8.0.2\Sdk\AutoImport.props" is correct, and that the file exists on disk. IOSTest C:\Program Files\dotnet\sdk\8.0.303\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.ImportWorkloads.props
Why am I getting this error?
Then I removed my project´s bin and obj folder and opened it again in Visual Studio Community 2022 (64-bit) Version 17.10.4. Then I saw that the NuGet packages automatically switched from version 8.0.61 to 8.0.70.
Why can I not use version 8.0.70 in my iOS project?

You created a MonoGame iOS Application, that is a kind of .NET for iOS application, it will create native iOS application, why you add the Microsoft.MAUI.Controls nugget package in it? Microsoft.MAUI.Controls packages apply for the cross-platform framework project (iOS, Windows, Android and Mac Catalyst).
If you want to implement user-interface in MonoGame iOS Application, you can refer to the Xamarin.iOS user-interface document. This document could be used in the .NET for iOS application.

This is happening in for me in a Maui project also after "dotnet workload restore". I've no idea what Aspire is and I've tried uninstalling but still get the error.

nuget package references are stored in the project file. you probably did not save the project file after updating the packages. so when reopened it was reverted. you should save all after updating packages. you should also delete the bin & object folders before doing a restore/build.
I suspect your dotnet workloads need updating or are corrupt. The Maui and Aspire workloads are often problematic:
