sample.xcodeproj cannot be opened because the project file cannot be parsed. while opening the Xib file in Xcode interface builder

Question

I am developing an app in Xamarin using Visual Studio for Mac.

When I try to open a .xib (or any other interface builder file) in Xcode(8.3) interface builder for designing, I get the error

sample.xcodeproj cannot be opened because the project file cannot be parsed.

Does anyone have solution to this?

Answer 1

Visual Studio for Mac Preview 8 (7.0 build 2845) fixes this problem.

Answer 2

I found that the problem was in Info.plist file. Some of the mandatory fields that are empty cannot be parsed when trying to open a .xib file. And in my case Minimum system version field somehow happened to be empty.
