Thanks for your help
Have you tried enabling generic value type sharing?
Go to the iOS project's options, iOS Build section. On the Advanced tab check: "Enable generic value type sharing".

I'm currently getting the following error and stacktrace when attempting to run UI Tests locally against my Xamarin.Android project. This error doesn't occur on every run, but its pretty frequent. A clean and rebuild will usually "fix" it, but when trying to run all tests is the suite this is a really annoying error.
I'm not really sure where to proceed from here. Any direction on where to look for debugging this error, or if anyone know what causes the error, would be greatly appreciated.

I also ran into this, and what worked for me was uninstalling the app on the device, then reinstalling with a fresh copy. Notably, I was connecting to a device that hadn't been used in a while, so it was several versions older than my current application.
Adding x86 as a supported ABI fixed this problem for me
I'm a noob for Visual Studio for Mac. My intention was to check out Xamarin development. My Visual Studio version is 7.3 (Build 799) Community Edition, I've installed on a MB Pro 2015 Mid model.
When I try to create a project in following way,
Multiplatform
App
Games (iOS, Mac)
SpriteKit Game (2D)
And then proceeded with the steps until pressing the create button giving project name and all it just gives me the following Alert and I cannot create the project.
Updated:
I found following Log by going to "Open Log Directory" menu item.

Has anybody out there encountered this kind of an issue? Any solutions or workarounds you already have worked out?
So the problem seems to be that if one of the project types used by the project template is unsupported then an unknown project type is created with an empty flavor guid. This then causes an exception in the Android designer.
In this case the Xamarin.iOS project type was considered to be unsupported since Xamarin.iOS was not installed.
This seems to be a bug in Visual Studio for Mac. Either the project template should not attempt to create a Xamarin.iOS project if it is not supported, or the unknown project should be created with no flavor guids instead of using an empty string.
I can't even compile the default project from visual studio. I created a new project from the new project menu in a fresh directory, changed the app identifier to my apple developer app name, and compile, and it tells me that Default-568#2x.png does not exist.
here is the full error:

This is a workaround to solve this issue.
I'm updating the tooling for my project llvm-fs, so I installed the new version of mono and tried to compile it. Using either mono 3.10.0 with fsharpc 3.1 under OS X or mono 3.2.8 with fsharpc 3.0 under ubuntu the compile fails with a stack overflow:

You can reproduce this error on linux or OS X by doing the following:
git clone git#github.com:fsprojects/llvm-fs.git
cd llvm-fs/
FSC=fsharpc ./build.bash
Under windows fsc 12.0.30815.0 the compile completes with no errors:
fsc --nologo --debug --sig:LLVMFSharp.fsi --target:library --out:LLVMFSharp.dll src/LLVM/FFIUtil.fs src/LLVM/Generated.fs src/LLVM/Core.fs src/LLVM/BitReader.fs src/LLVM/ExecutionEngine.fs src/LLVM/Extra.fs src/LLVM/Target.fs src/LLVM/Quote.fs
Is this a known issue and is there any way to work around it? I've tried passing different options to the mono runtime and none resulted in the compiler exiting normally. I do remember in the past mono has had some problems respecting tailcall instructions but I thought that those problems were mostly resolved. Thanks!
This is too long for a comment, but the error is triggered by this bit of code from generated.fs (in that commenting it out stops the stack overflow - there is an error later once this is commented out) (from line 6496-6506):
[<DllImport(
llvmAssemblyName,
EntryPoint="LLVMRunFunction",
CallingConvention=CallingConvention.Cdecl,
CharSet=CharSet.Ansi)>]
extern void* (* LLVMGenericValueRef *) runFunctionNative(

void* (* LLVMValueRef *) F,
uint32 NumArgs,
void* (* LLVMGenericValueRef* *) Args)
// I don't know how to generate an "F# friendly" version of LLVMRunFunction
The crash is occuring in the code that outputs the signature file.
Disabling the signature file fixes the problem (but there is still an underlying bug somewhere).
I have developed an ipad app in xamarin studio(monotouch), suddenly I cannot debug this app in ios device(ipad) any more, but in ios simulator everything works fine.
From the "Build Output" I got following information, any ideas would be nice.

This is probably caused by some oddity in your mounted file system in /Volumes/BOOTCAMP
Try moving your code out of it.
In the "iOS Build"->"Linker Options"->"Linker behavior" I set the value from "Link SDK assemblies only" to "Link all assemblies", and problem solved. But I still didn't understand the difference and don't know if there will be other problems by changing this setting.
