Ios Xcode设备不可用，未找到运行时配置文件

在以下环境中：

Xcode 8.3.2
react-native-cli 2.0.1
react-native: 0.44.0
macOS Sierra 10.12.5

刚刚更新了Xcode和macOS以运行React Native，并像几天前一样继续练习。。。但每次我尝试跑步时：

react-native run-ios

我得到一个错误：

Scanning 555 folders for symlinks in /Users/juangarcia/projects/react-tests/CountDown/node_modules (6ms)
Found Xcode project CountDown.xcodeproj

Could not find iPhone 6 simulator

我尝试查看可用设备的列表，得到：

react默认使用Iphone 6，但不可用

我怎样才能使它再次可用？为什么会发生这种情况？

pfff这比预期的要简单。。。当安装SO和Xcode时，由于某种原因，删除的所有设备列表。。。在本例中，进入Xcode UI菜单添加一个新的模拟器iPhone 6就足够了。。。我试着重新启动并返回，所以我不知道UI中有一个用于此的选项，因为我是XCode环境的新手。谢谢你的回答

在XCode菜单中，窗口-->设备-->添加新的模拟器…

node_modules/react native/local cli/runIOS/findMatchingSimulator.js

我替换了：

if（version.indexOf（'iOS'）！==0）

与

if（！version.includes（“iOS”）

及

if（simulator.availability！=='（available）

与

---

if（simulator.isAvailable！==true）

我在xCode 9和10.2中遇到了这个问题。

对于其他在这里遇到同样问题的人，以下是对我的帮助：

闭合xCode

重新启动你的笔记本电脑（我知道这是一个巨大的麻烦）

打开xCode并再次运行构建

TL；博士：

使用

xcrun-simctl-Upgrade

详情：

我可能是在安装了Xcode 10和Xcode 11（并且Xcode 10当前处于活动状态）的情况下执行了

xcrun simctl delete unavailable

之后遇到这种情况的

执行

xcrun-simctl-list运行时

我发现列出了iOS 13.1运行时：

iOS 11.4 (11.4 - 15F79) - com.apple.CoreSimulator.SimRuntime.iOS-11-4
iOS 13.1 (13.1 - 17A844) - com.apple.CoreSimulator.SimRuntime.iOS-13-1
tvOS 13.0 (13.0 - 17J585) - com.apple.CoreSimulator.SimRuntime.tvOS-13-0
watchOS 6.0 (6.0 - 17R575) - com.apple.CoreSimulator.SimRuntime.watchOS-6-0

但当我执行

xcrun simctl list

时，几个模拟器被列为不可用：

    iPhone 8 Plus (B08025C1-B7A2-40C0-B6D5-517EC8BB3C45) (Shutdown) (unavailable, runtime profile not found)
    iPhone Xs (0A1C1EAA-8E18-4508-9E14-C376D944984B) (Shutdown) (unavailable, runtime profile not found)
    iPhone Xs Max (84C692F5-6CF3-449D-B166-0EA26B1FAC4B) (Shutdown) (unavailable, runtime profile not found)
    iPhone Xʀ (7581E116-5CFB-4A94-94A0-30B5B8871874) (Shutdown) (unavailable, runtime profile not found)

我的解决方案是将不可用的模拟器升级到所需的iOS运行时（在我的例子中是iOS 13.1）：

xcrun-simctl升级模拟器\u ID“com.apple.CoreSimulator.SimRuntime.iOS-13-1”

为了避免对所有模拟器手动执行此操作，我编写了一个小ruby脚本来一次性升级所有iPhone：

#!/usr/bin/ruby

uuid_regex = /([0-9A-Z]{8}-[0-9A-Z]{4}-[0-9A-Z]{4}-[0-9A-Z]{4}-[0-9A-Z]{12})/
unavailable_iPhones = `xcrun simctl list | grep iPhone | grep "runtime profile not found"`.split("\n")
unavailable_iPhones.each do | row |
    uuid = row.match(uuid_regex).captures.first
    system("xcrun simctl upgrade #{uuid} \"com.apple.CoreSimulator.SimRuntime.iOS-13-1\"")
end

Xcode 12 beta 4解决方案中缺少ios14模拟器选项：

查看这篇关于

simctl

的精彩文章

我创建了一个iOS14 sim卡，因为XC12-beta4没有通过以下方式为我提供下载/创建选项：

xcrun simctl create

前

---

xcrun simctl创建iPhone-8Plus-14 com.apple.CoreSimulator.SimDeviceType.iPhone-8-Plus com.apple.CoreSimulator.SimRuntime.iOS-14-0

请检查系统中是否有iPhone6模拟器？我也有同样的问题。但我重新启动系统，它会对我有效。它们在Xcode中显示吗？在run按钮的右边。等等，所以你将所有模拟器的os版本升级到了iOS 13.1？不，只有那些被列为“不可用”的版本…我在更新到Xcode 12后出现了这个问题，退出Xcode，模拟器修复了这个问题。
