问题 I have just updated my Xcode to 11.4 from 11.3 and my project written in SwiftUI started to behave differently. I used to call toggle() function for boolean values and it used to trigger didSet property observer, however, it is not working any more. Let' say we have a State property called isSettingOn . I used to call this: isSettingOn.toggle() which was triggering didSet observer of the property. Now, only if I call this: isSettingOn = true it is working. My projects are all based on this

问题 I just updated XCode and the command line tools to 11.4. Now when I run svn it says "svn: error: The subversion command line tools are no longer provided by Xcode". The release notes say "Command line tool support for Subversion — including svn, git-svn, and related commands is no longer provided by Xcode. If you need Subversion or related command line tools the you need to install the Command Line Tools package by running xcode-select --install." I seem to be in a loop here, as the tools are

问题 Our app crash on os 10.3.3 10.3.4, iPhone 5c /5 iPad4 (armv7s 32) compiled by Xcode 11.4, swift optimization on. We find the PC register point to a hole address without virtual address and no stack information. If we close swift optimization, it works. So do anyone find the problem and any solution? It's certain that it's related to Xcode 11.4 swift optimization. I find the same question here. https://www.reddit.com/r/iOSProgramming/comments/frcpsc/xcode_114_builds_crashes_on_ios_10/ Incident
