Convert iOS application to 64bit

Question

I'm try to convert my iPhone application to 64bit , because the apple announce that apps can be uploaded only with 64bit support from February.

From what i read i need to add arm64 to this values(In the targets):

Architecture
Valid Architecture

The problem not is that when i add the arm64 and build the application so i get build failed message. But there is no error message in the Issue Navigator .

Any idea why it happen?

There will be an error in the Report Navigator. In the left hand panel in Xcode it is the right hand button, highlighted blue in the attached screen shot. You may need to scroll up the list to see the error.
