Failed to find a suitable device

更新了 Xcode10.3 后运行报错
Assets.xcassets:-1: Failed to find a suitable device for the type IBSimDeviceTypeiPad2x (com.apple.dt.Xcode.IBSimDeviceType.iPad-2x) with runtime iOS 12.4 (12.4 - 16G73) - com.apple.CoreSimulator.SimRuntime.iOS-12-4

方法1：

$ sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

# 可用可不用 看情况
$ sudo xcode-select -s  /Applications/Xcode.app/Contents/Developer

方法2：

$ xcrun simctl erase all

一脸黑人问号 ？？？

不定期更新 不合适的地方 还请指点~ 感激不尽
