10x worse Swift performance due to Obj-C bridging in framework?

问题 I'm working on a performance-intensive Swift app, with most of the fast code residing inside a framework. One of my expensive functions involves iterating over a two-million element array of structs. Unfortunately, the Obj-C bridge makes Swift Array performance about an order of magnitude slower than it should be. About 90% of my cycles are wasted on _ArrayBuffer._checkInoutAndNativeTypeCheckedBounds and bridging-related retains and releases. If I drop the framework and simply include those

Changed target setting Defines Module to YES. Similarly, "Product Module Name" is set to "MyProject". I can see the MyProject-swift.h a file name for the setting "Objective-C Generated Interface Header

So I'm trying to import this class in the bridging header. But after importing this file the app gives an error on the "#import "Sonic-Swift.h"" line "File not found". failed to emit precompiled header '/Users/krishna_mac_2/Library/Developer/Xcode

问题 I have a situation. I would appreciated if anyone has a solution for this I have an objC enum say Abc I declare this in a swift class, say, MySwiftClass.swift as var abc : Abc! I have created an instance of MySwiftClass ( mySwiftClass ) in another ObjC class (myObjC.m file) In myObjC.m, I’m trying to access enum Abc as mySwiftClass.abc . This is throwing an error - “Property ‘abc’ not found on object of type MySwiftClass *”. Basically the enum is not added as property in the “ProjectName

I am trying to add objective-c libraries to my Swift 3 project (Xcode 8 IDE). But objective c interface header is not getting generated automatically. I tried to add bridging header manually but showing linking error saying bridging header .h is not found. Any help would be appreciated :) Augustine P A Here the solution for the issue. Create a new header file and name it like " your project name-Bridging-Header.h ". The file must be saved to your project folder Select your xcode project -> select your build target -> select build settings -> click the "all" option at the top -> search for
