Hi im experiencing a crash when applying a extension macro.
I cannot share the actual source code since its from my job and i did not manage to extract a reproducible example (the macro is applied to a lot of types and i dont know where to start searching)
I suspect that this is a compiler bug, since when i inline the macros in some places it builds without problems
With Xcode 15 Beta 7

For extra context, I have a macro that is both a member and extension macro.
it is supposed to work roughly like this allowing me to extract a open-api spec from my swift types.
protocol APIModel: Codable {
public static func resolveSchema(in registry: Registry) -> JSONSchema
}
@APIModel
struct MyType {
let int: Int
let string: String
}
// expands to
struct MyType {
let int: Int
let string: String
// generated by member macro
public init(from decoder: Decoder) throws { // decode }
public func encode(to encoder: Encoder) throws { // decode }
public static func resolveSchema(in registry: Registry) -> JSONSchema {
// generate json-schema describing this type and store it in the registry
}
}
// generated by extension macro
extension MyType: APIModel {}
the macro is defined like this
@attached(extension, conformances: APIModel)
// @attached(conformance, conformances: APIModel)
@attached(
member,
names:
named(init(from:)),
named(encode(to:)),
named(resolveSchema(in:))
)
public macro APIModel() = #externalMacro(
module: "OpenAPIMacros",
type: "APIModelMacro"
)
Hoping this helps resolve the issue or looking for tips how to resolve it.
Happy to provide extra info if needed via a private channel
