问题 I am using swift 2 and Xcode7 for iOS9. I want to know if I can maintain a function (that checks for something to delete) running "forever" even if the user kills the app? I am deleting contacts from the contact list according to some rules and time. It is running ok, but just with the app opened or in second plan.

问题 When using XCode to compile a Cocoa application, I'm running a custom Bash script in the build phase. Unfortunately, I'm having to spell out full paths.

问题 After upgrading my project to Swift 2.0 and using Xcode 7 (GM) I noticed some of my view controllers freeze the app on navigation. Instruments show me that CPU usage is over 9000% and is used by UIKit and Foundation. Have you encountered this problem? 回答1: It seems to be one of those Interface Builder issues. I've successfully defeated this by removing any text from UITextView in storyboard. And it comes again if I set text property back. Hopefully, this will help someone to not waste

问题 In my swift project, I am using convergence dev branch source code. I have added ADALiOS files manually in my project. Currently retrieving access token from refresh token is a problem.
