bridging-header

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

问题 Here I'm attaching a screenshot of created header file I have created a new header file in xcode and named it as (projectname)-Bridging-Header.h. But I am not able to find the path and make it work. How to find the path of the file? 回答1: First go to project build setting, Then search Swift in in the search box After that you will find a Objective C Bridging Header option in Swift Compiler Code Generation Area Add the bridging header path for this Objective C Bridging Header Option Path should

问题 I added to my project bridging-header file so I can use opencv in swift. I decided that I don't need opencv so I deleted the bridging header file , after I did it I couldn't run my project because of this error: :0: error: error opening input file '/Users/user1/Desktop/project_name/project_name/project_name-Bridging-Header.h' (No such file or directory) this error appeared in the Compile Swift source files > Precompile bridging header section. I tried cleaning my derived data and I tried

问题 I updated to Xcode 8.3 and Swift 3.1 and got this warning in my bridging header file, referencing to an Objective-C header file: Non-portable path to file "File.h"; specified path differs in case from file name on disk How can I resolve this? 回答1: It turned out that I misspelled the file's name, the correct name was "FILE.h" instead of "File.h". The warning appeared because of the soon coming APFS to macOS. 回答2: In my case, the !!project folder name!! isn't match the bridging header path. I

问题 In regards to a "dynamic framework" target, I need to bridge internal (private) objective-c headers to my swift counterparts. From my understanding I need to use a private module. Some of these swift counterparts are bridged back to objective-c using the @objc class TheClass syntax. I've gone ahead and created a module.modulemap and a module.private.modulemap file in a directory under $SRCROOT and added the "necessary" flags to the build settings. SWIFT_INCLUDE_PATHS =>$(SRCROOT)/... I've

问题 EDIT: Getting negatives for such a detailed and HONEST question? Sometimes I don't really get Stack Overflow. Really. Hi, I'm trying to create a PoC using Swift 5 (Xcode 10.2.1) and a modern rendition of ncurses (in this case, MacPorts' one, some 6.1.2018XXXX version) My Poc has no code as of now, as my problems start before being able to add any sensible line to my .swift files. So far I've done the following things: 1.- I have a proper working MacPorts ncurses library installed: that means

问题 In my xcode workspace (using cocoapods), I am not able to add Flurry.h in my bridging header . Other headers from other pods like Dropbox, etc are working fine. Only Flurry headers are not being recognized. I have my podfile as below: platform :ios, '9.0' use_frameworks! pod 'Alamofire', '~> 3.1' pod 'SwiftyDropbox', '~> 2.0.3' pod 'Flurry-iOS-SDK/FlurrySDK' pod 'Flurry-iOS-SDK/FlurryAds' pod 'Parse' My Bridging Header is as below (with the problem highlighted!): Here is the Pods project

问题 I have an existing Obj-C project that houses many targets that all share the same AppDelegate. I want to bridge a swift class that is used by select targets. I can do this easily when I have one target. When I add a swift file to the project, I select the desired targets and the necessary bridging-header.h files are generated, but when I try to import those -swift.h files, they are can't be found. Are there steps I'm missing when it comes to projects that have multiple build targets? EDIT -
