Slow builds on Mac M1

[davidortinau]

Description

Here are build logs for iOS and Android on a newly installed M1 running Ventura, net7 and VS Mac public GA builds.

In general Android takes anywhere from 130s to 300+s to build cold. iOS is slightly better around 110s.

Verified that CLI is also long.

When I installed clean I noticed that installing MAUI uses Rosetta. Wonder how much this impacts build perf.

Steps to Reproduce

I'm building the CarouselViewDemos project after updating the project to net7.

<TargetFrameworks>net7.0-ios16.0;net7.0-maccatalyst15.4;net7.0-android33.0</TargetFrameworks>

Just to check does dotnet --info say it is arm64?

Android at least will need Rosetta for a while, Google's aapt2 is not built for arm64, for example...

CLI too, @jsuarezruiz . This isn't a VS issue.

dotnet build -f net7.0-android33.0 -bl

It doesn't make sense why this task is taking 7 minutes???

This task takes ~52ms on my M1, and should be about the same amount of time for any build:

I'll try the project above, though.

This issue is being closed due to inactivity. If this issue is still affecting you, please follow the steps above to use the VS Feedback Tool to report the issue.

I'm having the same issue as the OP.

I was about to start a new Xcode/SwiftUI project and decided to finally start playing with MAUI. The File->New MAUI app for .NET 7 takes almost ten minutes to build.

If however I delete and recreate using .NET 6, it's almost instantaneous.

There is definitely something wrong with this product. How do we address this?

For now, I can stick with .NET 6 but that's officially out of support, so that's not a real solution either.
