Problem

You can't use bridging headers within a framework.

Solution 1 (umbrella header):

Xcode will automatically create umbrella header for you Cocoa Framework project. That will be the file named <FrameworkName>.h in the <FrameworkName> group/folder (where the rest of your sources are).

1. To include the required Obj-C header you need to set it as Public: select it in the project explorer (left pane) and change the property Target Membership (left—Inspectors—pane) from Project to Public.
2. Open umbrella header (<FrameworkName>.h) and import the required header as:

1-1 스위프트 API 디자인 가이드라인

https://swift.org/documentation/api-design-guidelines/

• 사용할 때 기준으로 명확하게 작성하는 게 가장 중요한 지향점이다. 메소드나 프로퍼티 같은 개발 요소는 한 번만 선언하고 반복적으로 사용한다. API를 만들 때는 사용하기 명확하고 편하게 만들어야 한다. 설계를 검증할 때 선언 부분을 읽는 것만으로는 부족하다. 그 대신 사용하는 상황에서 맥락에 맞고 명확한 지 늘 고려해야 한다.

• 명확한 표현이 압축한 간결성보다 더 중요하다. 스위프트 코드는 압축해서 간결하게 작성할 수 있지만, 단지 글자수를 줄여서 가장 짧은 코드를 만드는 게 목표는 아니다. 스위프트 코드의 간결성은 자연스럽게 반복적으로 재사용하는 코드(boilerplate)를 줄이는 기능과 강한 타입 시스템의 부수효과로 드러날 뿐이다.

so A and B are structurally identical
C reverses the order of the 8 and 32 bit Ints
and D substitutes a string for the Int8
then I try to read aaaa’s bits using B C and D overlays 😊
C is printing the 8 bits of the A integer j and then the first 8 bits of integer k but somehow that still works out to one

when I hit D it doesn’t find a string so prints a blank

but the important point is: it doesn’t check anything, and doesn’t crash
