I'm having problems doing 'Build and Run the scheme' in xcode to pass the project to an iPhone 4s device and test what I'm developing, from one day to the next it has stopped working and I have not touched anything on the project configuration.
The error he gives me is this:
Code signing is required for product type 'Unit Test Bundle' in SDK 'iOS 10.1'
If you need any more details do not hesitate to ask me, I am new to the development of ios and I'm in a project made by other people who are no longer in the company.
