ios - iOS Simulator connection timed out

Question

When I try to simulate my iOS app using Xcode version 9.4 simulator, it keeps on loading and loading till it sends me the following message:

Failed to initiate service connection to simulator. Connection timed out

My Internet is fast and I have updated my macOS HighSeirra 10.13.4 in no time.

Answer 1

正确关闭Xcode（也从您的扩展坞）

关闭模拟器

并重新启动Xcode 和模拟器。

让它构建和索引项目

之后它应该可以正常工作..

谢谢

快乐编码 ;)
