Output from build
I have created an iOS Bindings Library for my cross platform project called iOS.Crop. The native library I'm linking to is TOCropViewController 2.0.12. I used a couple of tutorials for using cocoa pods.
I added the iOS.Crop Bindings Library to the project on my Mac as well as all of the Objective Sharpie commands (obviously). I added the generated ToCropViewController.framework as a Native Reference and updated the APIDefinition and Structs. The iOS.Crop project compiled fine.
I then added a reference to iOS.Crop in my iOS project and made calls to the native library and everything worked fine on my Mac. The problem is when I go back to my windows machine with VS 2017. The native project (iOS.Crop) builds fine, but my iOS project throws the following error (Krizzma.iOS is the name of my iOS project) .
Error Native linking failed for '/Users/jeremyalley/Library/Caches/Xamarin/mtbs/builds/Krizzma.iOS/77444036d2543f1c892fafac1b7559f2/obj/iPhone/Debug/device-builds/iphone7.2-10.3.2/mtouch-cache/arm64/libiOS.Crop.dll.dylib'.

Thanks for looking into this. I have attached a sample project.
Hi Prashant, any update on this issue? Is there anything else I can provide?
# Non Engineering team observations -
Building solution from VS on Windows and **Mac** fails with following error
> error : Native linking error: framework not found TOCropViewController
While building just a binding project works on both Mac and Windows
Looks like the attached test case is missing the TOCropViewController.framework
Could you share it with us? It will help us to troubleshoot the issue
I am marking this bug RESOLVED INVALID.
In the sample the _TOCropViewController_ static library is targeting devices (armv7 & arm7s), we get build errors on building the project targeting simulator.
To fix this issue -
Remove TOCropViewController.framework from native references
Rename `TOCropViewController` to `TOCropViewController.a`
Add TOCropViewController.a to the iOS.Crop project
Use the device build configuration i.e Debug|iPhone or Release|iPhone
@Jeremy, please reopen the bug if you continue to have an issue with the build
Thanks again for the assistance. I followed the steps above and I was able to get the BindingsTest.iOS project to build. However, when I deploy to my device using Debug|iPhone the app crashes. If I remove all references to the iOS.Crop project everything works fine. Were you able to deploy it to a device?
You mentioned that the static library is targeting devices (armv7 & arm7s). When I do a lipo -info on the library on my mac, it states the architectures are: armv7 and arm64. Are you seeing something different?
> However, when I deploy to my device using Debug|iPhone the app crashes.
Could you share the new crash logs? I am not able to see this issue.
> Are you seeing something different?
armv7 and arm64 indicate that library is built for devices. I see same output.
Simulator architecture is `i386`
