Hello,
I have an open source Objective C framework, which I'd like to provide using Swift Package Manager as well.
Normally, I have public headers set in the Xcode project, which, when the framework is built, are copied under the framework bundle, and are discovered when linked with by Xcode.
I can't, however get it to work with SwiftPM.
I created a modulemap for my framework (there are more public headers than just the umbrella header):
framework module LNPopupController {
umbrella header "LNPopupController.h"
export *
module * { export * }
}
and I define the library like so in the Package.swift:
let package = Package(
name: "LNPopupController",
platforms: [
.iOS(.v12),
.macOS(.v10_15)
],
products: [
// Products define the executables and libraries a package produces, and make them visible to other packages.
.library(
name: "LNPopupController",
type: .dynamic,
targets: ["LNPopupController"]),
],
dependencies: [
// Dependencies declare other packages that this package depends on.
// .package(url: /* package url */, from: "1.0.0"),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages this package depends on.
.target(
name: "LNPopupController",
dependencies: [],
path: "LNPopupController",
publicHeadersPath: ".",
cSettings: [
.headerSearchPath("."),
.headerSearchPath("Private"),
]),
]
)
When added as a project dependency in Xcode, the framework compiles just fine, but when the dependent target attempts to import LNPopupController
, an error is thrown: umbrella header 'LNPopupController.h' not found
Looking at the build folder, indeed, I see that Xcode has built a binary, but has not copied the public headers.
Any way to specify which headers are public, and make the build system copy them for import?
My attempts to play with SPM are here: https://github.com/LeoNatan/LNPopupController/tree/SPM
Thanks!
