Xamarin Forms iOS Deploy with simulator Failed To Install ERROR

Question

I installed xamarin on the mac and followed the instructions here to to allow remote logins (so that I can use a simulator on my windows machine), I was able to connect via mac agent without problems, however when I run i get this error:

Was wondering if any of you had these problems?

When I created a solution in xamarin studio on my MAC and ran the app on the MAC it worked without giving any errors... any ideas that might help?

Answer 1

I've got the same problem. After searching the solution for 4 hours... and reading all Internet with no result, I found that problem is when on the Mac machine in user account confuguration you have different NAME ACCOUNT and FULL NAME ACCOUNT. These 2 fields must be filed with the same names. Otherwise, the path from VS iosEMualtor doesn't match (it takes FULL NAME).

To do so just follow the steps of this Apple-KB-Article: https://support.apple.com/en-us/HT201548 (Yosemite instructions shown below)

1. Choose Apple menu  > System Preferences, then click Users & Groups.
2. Click the lock button, then enter an administrator name and password.
3. From the list of users, Control-click or right-click the user that you want to rename. Choose Advanced Options from the shortcut menu.
4. Change the name in the “Full name” field, then click OK.

Answer 2

I got this error yesterday when I updated xamarin to the latest on both mac and windows. I was able to run the simulator on mac but not on windows. I fixed it by installing the iso simulator to the preview version on windows and the remote simulator works again. iOS Simulator (for Windows)

Answer 3

1. delete folder /Users/xxxx/Library/Caches/Xamarin/mtbs/builds/ProjectName (on Mac)
2. Rebuild Project
3. run debug on simulatorPhone
