I have defined some constants in my .m
files that I need to access form my swift code. They are defined:
const CGFloat testValue = 40.0;
and in my other objective-c .m
files I can access them by using extern
:
extern const CGFloat testValue
Is there an equivalent way of making these constants accessible from the .swift files?
Add the extern
to your bridging header and Swift should be able to access it.
This simple test worked for me:
ObjCTest.m
#import <Foundation/Foundation.h>
const CGFloat testValue = 40.0;
ObjCSwiftBridgeTest-Bridging-Header.h
#import <Foundation/Foundation.h>
extern const CGFloat testValue;
main.swift
println(testValue);
Output
40.0
Just put the var
declaration above the class - it will become a global variable.
