BaseUtils

Problem:

  • URLUtils contains a property queryParams implemented in Objective-C and apparently is NOT available in Swift on URL types but only on NSURL type. This looks odd to me because when declaring the same category in an App and using the bridging header file, then queryParams is also usable from URL type too.

Is this the expected behaviour for SPM packages containing Objective-C code?

// Swift file.
import URLUtils

func testURL() throws { // Problem: Testing with URL does NOT compile (With NSURL is compiles OK)
    let url = URL(string: "https://domain.com/path?a=123")!
    let queryParams = url.queryParams // error: value of type 'URL' has no member 'queryParams'
}

Try it:

Run swift test.

Stackoverflow & Swift Forums question

I asked the same question:

2023/06/14 Solution added

Solution explanation: NSURL and URL and not the same type and the compiler does the magic that makes them look like same, it is implemented using ReferenceConvertible. I think that only happens for types inside Foundation and/or App module. However if I create my own frameworks/library it will be a different module, different compiling time. Hence, I will not get the same benefits so I need to explicitly create a target for Swift too.
