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 In an attempt to optimize the build time of my app I've added the following to my OTHER_SWIFT_FLAGS : OTHER_SWIFT_FLAGS = -Xfrontend -warn-long-expression-type-checking=75 -Xfrontend -warn-long-function-bodies=75 I got a warnings for this specific type checking being slow, and I cannot figure out if I can help the compiler in some way here. var delay: TimeInterval = TimeInterval(index) * 0.05 Any suggestions what can be done to speed up the compile time for such basic arithmetic operations up

问题 I'm making my app modularized using Swift Package Manager by separating various parts of the app into different layers (packages): Presentation, Business and Data to make it as clean as possible, and I link those manually created packages with the project in project settings -> Frameworks, Libraries and Embedded Content section. However, I'm still in need for Cocoa Pods in some parts of the project, for simplicity my pod file contains the following: target 'SampleApp' do use_frameworks! pod

问题 I am trying to debug my Maya plugin that I build for Maya 2013 using Xcode 4.6.3 debugging features.

I'm trying to set the accessibility label/identifier/value on the image so that I can verify its presence via a UIAutomation test, but no matter what I do I'm not getting the accessibility label/identifier/value on the DOM in my test. Here are the things I have tried: Setting directly on the image. UIImage *uiImage = [UIImage imageWithData:bfCaseStudy.image]; uiImage

问题 I am creating backend based on Vapor 3.1.10 using Xcode 11.2 and Swift 5.1, database is PostgreSQL 12. I have a question: how to interact with database (CRUD) without POST and GET requests. All tutorials show how to CRUD only based on Request through HTTPS. But what if my app needs to save something in database without interacting with network? Look at my code: import Vapor import FluentPostgreSQL final class Device: PostgreSQLModel { var id: Int? var isWorking: Bool var serial: Int init
