我在我的 M1 MacBook Pro 上运行 Xcode 12.2 (12B45b)。每当我尝试在旧版 iOS 上运行模拟器时，例如:
这是行不通的。 Xcode 弹出这个错误:
当我按下 Details 时，会弹出一个屏幕显示:

System Information
macOS Version 11.0 (Build 20A2411)
Xcode 12.2 (17535) (Build 12B45b)

但是，如果我运行 14.2 等较新的 iOS，它会完美运行。这是 Xcode 预装的运行时。
我看了这个问题，iOS Simulator is Crashing on startup ，但答案几乎没有用。其他一些人在 Dev Forums 上遇到了同样的问题, 但也没有人有解决方案。
编辑: release notes 上似乎提到了这一点对于 Xcode 12.2:
Simulator runtimes for iOS 13, tvOS 13, and watchOS 6 and earlier don’t work on the Developer Transition Kit. Preferences offers these runtimes for download, but creating a simulated device from one of these runtimes fails, claiming the runtime is unavailable. Other Macs with Apple silicon support a limited set of older simulator runtimes for iOS and tvOS. (66115743, 70472441) (FB8157217)
最佳答案
我通过删除模拟器缓存解决了这个问题:
~/Library/Developer/CoreSimulator/Caches
macOS 蒙特雷 12.0.1，Xcode 13.3.1
关于ios - 在较旧的 iOS 模拟器上运行时，错误 "Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/65172944/
