종종 Xcode 에서 소스 자동완성이 안될 때가 있다. 아래의 방법으로 해결

Xcode 안에서

CMD + SHIFT + K                       프로젝트 클린

CMD + SHIFT + OPTION + K      빌드폴더 클린

Preference -> Locations 에서  DerivedData의 작은회색경로표시의 화살표 클릭해서 파인더에서 DerivedData지우기

1

Run this command in the project directory if you use cocoapods:

2

Clean Cached Data

Clean the Project -> Cmd+Shift+K

Clean the Build Folder -> Cmd+Shift+Option+K

If you skipped step one:
Delete Derived Data
Xcode Preferences -> Locations ->
Arrow Symbol Takes you to DerrivedData -> Delete Folder

3

Check your Build Phase's Compile Sources.

Every .swift and .m file in the project should be in this list or it won't autocomplete in those files.

4

Optimize your Editor:

Use fileprivate on every class property and function that you can to reduce the scope of the Compilers work per item.

Write modular/OOP code so you have less code for the compiler to read.

Avoid using Type Inferance when the result is a complex calculation, and try to break down complex calculations into let this = smallerOperation statements
