My assembly code generated for PowerPC architecture code 2 is Its assembly code generated for PowerPC architecture Code 1 is Should be in your Objective-C++ (.mm) file, it's useless in the bridging header, since Swift can't make sense of C++ anyhow. Interface is declared in the bridging header, but I don't see an implementation. In the project you attempted to build, I see where the #include "SuperpoweredBandpassFilterbank.h"įor C++ code, too, but they are probably using #import "SuperpoweredFrequencies-Bridging-Header.h" , you will see that it imports Objective-C headers: , which is not part of the library, but of the example, and is implemented in The bridging header in the SuperpoweredFrequencies example that you looked at introduces a From what I'm seeing you can mix Objective-C and C++ code in Objective-C++, which allows Objective-C to use C++ classes. However, you cannot interface directly with C++, and that's where Objective-C++ comes to the rescue. I haven't programmed in Objective-C++, but I do have experience with C, C++, Objective-C, and Swift, so here are some observations and ideas based on looking at the Superpowered SDK and sample code.Ī bridging header lets Swift interface directly with Objective-C, and since Objective-C is a strict superset of C, this implies interfacing with C as well. mm and I implementĪnd in my methods, I call the corresponding method of theĪnd finally I include all the wrapped classes in my Bridging-Header, like that I can instantiate my wrapped objects from Swift. , and I also prototype in it all the methods of the h file where I prototype my wrapper with the name Here is an example with the SuperpoweredRecorder object from the lib : So, as Swift cannot interact directly with C++ but can with Objective-C, I had to create objects in Objective-C++ (.mm file, a mix between C++ and Objective-C) that wrap C++ classes of the lib Superpowered. So yes, I'm a little bit confused with all that stuff, can you help me to understand how can I use all the Superpowered lib in my Swift project please ?Īs I said in comment to I had a little conversation with the CTO of Superpowered that helped me a lot to find the solution below. mm file and I don't know what I have to put in that. cpp files and I have to create a wrapper for cpp (a little bit like I did with the bridging header, no ?) but that includes a. Until here, it's great, except that I can't for exemple create aįile in my Bridging-Header-File I have these errors : My viewController file where the code in Swift is, and where I can create a Superpowered object thank's to the Bridging-Header-File, and call the methods that I've put in it. The same Bridging-Header-File that in the sample project except that I include So with this sample project in mind, I've created my own project, here is some screenshots : It comes out from nowhere, not even their lib files. The viewController file where the code in Swift is, and where I can create a Superpowered object thank's to the Bridging-Header-File, and call the methods that I've put in it.Īnd wtf I don't even understand why this Objective-C++ file is here and what it contains.
The Bridging-Header-File with the prototypes of the methods of the lib that I want to use within my Swift code (I don't like this but if it's the only way.). Here is some screenshots of the sample project with what I understand and what I don't :
SUPERPOWERED LATENCY TEST HOW TO
Superpowered gives us a sample app to show how to mix Objective-C++ and use their lib within a Swift project (Here's a link to the git if you want XCode: Undefined symbols for architecture arm64 errorĪnd I tried all the solutions that I found on the web for that, still no way to compile. h files path in Xcode > Target > Build Settings > Search Paths > Library Search Paths.īut with that I have the error "ld: symbol(s) not found for architecture arm64" a in "Linked Frameworks and Libraries" in Xcode > Target > General (and so in Xcode > Target > Build phases > "Link Binary With Libraries" too) and index the. a and headers files in my project (Xcode create for me a bridging header file), add the. I want to make an app in Swift that simply record via the mic of the iPhone and then play the sound recorded.įor that, I'd like to use the lib Superpowered that is a static library with header files.įor that, I tried to drag and drop the.
