Swifty
模块只是一个简单的结构
// MyStruct.swift
public struct MyStruct {
public var text = "Hello, World!"
public init() {
}
}
在Objc-cli
我试着像这样链接swift模块。
// main.m
#import <Foundation/Foundation.h>
@import Swifty <---- Not found
int main() {
NSLog(@"Hello from Objc");
return 0;
}
以下是Package.swift
的样子:
// Package.swift
import PackageDescription
let package = Package(
name: "MyTest",
targets: [
Target(name: "Swifty", dependencies: []),
Target(name: "Objc-cli", dependencies: ["Swifty"]),
]
)
遗憾的是,编译器无法识别objective-c模块中的Swifty
模块。这是输出:
$ swift build
Compile Swift Module 'Swifty' (1 sources)
Compile Objc-cli main.m
/tmp/TestPackage/Sources/Objc-cli/main.m:10:9: fatal error: module 'Swifty' not found
@import Swifty
~~~~~~~^~~~~~
1 error generated.
<unknown>:0: error: build had 1 command failures
我错过了什么或现在根本不可能吗?
答案 0 :(得分:0)
现在无法在C模块中导入Swift模块,它只能以另一种方式工作,将C导入Swift。
