Failed to emit precompiled header for bridging header

Question

I downloaded a project from GitHub, then pod the following files, some of which are written by OBJ-C and I used a bridge header.

pod ‘SnapKit’
pod ‘MJRefresh         


        

Answer 1

Note this can also happen if your bridging header imports Objective-C code that itself imports your app's Swift module via myproject-Swift.h. The solution is to use forward declarations for your Swift types and import the project Swift module in the .m file.

@class MySwiftClass or...

typedef NS_ENUM(NSInteger, MySwiftEnumType)

MySwiftEnumType is the lowest level name even for classes. So Swift enum MyClass.MySwiftEnumType becomes just MySwiftEnumType
