Swift: Use of undeclared type

Question

I'm implementing a class but I'm getting this error:

Use of undeclared type 'myProtocol'

Here is my code:

class LocalContactService: myProtocol{

Any of you knows why I'm getting this error?

Answer 1

i had the same error .in my case i found accidentally that i added my swift files into "copy bundle resource" in "build phase" i removed all swift file except assets then everything worked fine.

Answer 2

the issue is caused when the classes in question do not belong to the same targets, usually the test target is missing. Just make sure the following check boxes are ticked. you can refer to original answer: https://stackoverflow.com/a/30737191/3992606
