Error: error MT: Failed to launch the simulator. MT0069: The app directory doesn't exist

Question

I use in order to develop cross platform application in xamarin forms but I have an issue. I use vs 2015 enterprise. There is a problem, when I simulate my application on iphoneSimulator. I selected "Configuration" mode as Debug and "Platform" mode as IphoneSimulator. In Windows side I use Xamarin.ios 11.2 and macbook side is same xamarin.ios sdk too. And I can connect windows to macbook successfully. I use xcode version 9.2.

When I run my application,

Launch failed. The app 'ADF.XPF.iOS' could not be launched on 'iPhone 5s iOS 11.2'. Error: error MT0069: The app directory '/Users/yazilim/Library/Caches/Xamarin/mtbs/builds/ADF.XPF.iOS/3d07b519b07c870401ed8b5058cf1d91/bin/iPhoneSimulator/Debug/trgovegmmobil.app' does not exist.

Can you help me about it ?

Answer 1

I hope this is helpful for somebody.

I had the same problem.

The message says that some folder of the path does not exists, so in my case i went to the MAC and i realized than the folder mtbs was not created.

Solution

Create the missing folder

After that clean, rebuild and launch the application again.

Answer 2

I also met this before.

1.Delete the app in simulator

2.Delete bin,obj folder

3.Run again

This should solve the problem.

Answer 3

I had a similar problem, nothing helped until I manually added the Xamarin.Build.Download package version 0.10.0

YourApp.iOS.csproj:

<PackageReference Include = "Xamarin.Build.Download" Version = "0.10.0" />

The accepted answer did not work for me. I took a slightly more radical reproach, and re-cloned my entire GitHub repository on my windows machine. I didn't change anything on the mac, and it worked first time.
