What can cause this? It works in Xcode 11 but not in Xcode 12. 回答1: So it problem was my project had permissions that it can only run in sudo mode. When I tried to run the simulator in sudo mode, it failed. I had to change the permissions of my project, to be able to run in non sudo mode. When this

问题 Is there a way to include the architecture in a CocoaPods Podfile ? I am trying to build my app for both 32 and 64 bit but when I switch to Standard architectures (including 64-bit) in my project's build settings, it complains that I should let it automatically choose architectures. Doing this reverts my project back to Standard architectures . I have a feeling that Xcode is doing this because the Pods project (in my Xcworkspace) does not include 64-bit in its architectures. Is there a way to

问题 I've previously compiled OpenCV 3.0 successfully following this guide, which essentially consists of the following steps: Download all the prerequisites (XCode, Command Line Tools, CMake and OpenCV source) Build static libs by configuring CMake (via gui) with: Uncheck BUILD_SHARED_LIBS Uncheck BUILD_TESTS Add an SDK path to CMAKE_OSX_SYSROOT (if it matters, I used /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk ). Add x86_64 to CMAKE_OSX

问题 I am in the process of updating a project to iOS 11/Swift 4. I have updated to Swift 3.2 and have a project that builds with one warning: "Conversion to Swift 4 available". So I click the warning and start the migration assistant with the option "Minimize Inference" when asked about Swift 4 @objc Inference. The build fails quite quickly with this message: Command failed due to signal: Segmentation fault: 11 Stack trace: 0 swift 0x000000010afabdba PrintStackTraceSignalHandler(void*) + 42 1

问题 I found an interesting question about @available in Swift. I added a var "UISwipeActionsConfiguration" that supports iOS 11 and above to the TableView I encapsulated to support the left-slide edit and delete function of the list cell. I tried to imitate the writing of UITableView to decorate the Var, but the IDE directly compiles and reports an error. I can only try another set get method to decorate. I can't help but doubt how Apple's open source Swift source code is hidden. Compiled. Below
