Xcode 设备不可用，未找到运行时配置文件

Question

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

刚刚将 Xcode 和 macOS 更新为运行 React Native 并像几天前一样继续练习......但每次我尝试运行:

react-native run-ios

我收到错误：

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列表，我得到：

react 默认需要 Iphone 6 才能使用，但它不可用

我怎样才能让它再次可用？为什么会这样？

Answer 1

pfff 它比预期的要简单...当安装 SO 和 Xcode 时，出于某种原因，整个设备列表被删除...去 Xcode UI菜单在这种情况下添加一个新的模拟器 iPhone 6 就足够了......我尝试重新启动并返回，等等不知道 UI 中有一个选项，因为我是新手 XCode环境。感谢您的回答。

在XCode菜单中，Window --> 设备 --> 添加新模拟器...

Answer 2

我去了 node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

我已经替换了：

if (version.indexOf('iOS') !== 0 )

和

if (!version.includes("iOS" ))

和

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

和

if (simulator.isAvailable !== true)

Answer 3

我在 xCode 9 和 10.2 中遇到过这个问题。

对于其他遇到同样问题的人，以下是对我有帮助的内容：

关闭xCode
重新启动你的笔记本电脑（我知道这很糟糕）
打开xCode并运行再次构建

Answer 4

TL;DR:

使用 xcrun simctl upgrade

将不可用的模拟器升级到最新的（或所需的）iOS 运行时

详情：

我可能在执行 xcrun simctl delete unavailable 之后遇到了这种情况，同时安装了 Xcode 10 和 Xcode 11（并且 Xcode 10 当前处于活动状态）。

正在执行 xcrun simctl list runtimes 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

但是当我执行xcrun simctl list时，有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 upgrade SIMULATOR_ID "com.apple.CoreSimulator.SimRuntime.iOS-13-1"

为了避免必须为所有模拟器手动执行此操作，我编写了这个小 ruby 脚本来一次升级所有 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

Answer 5

Xcode 12 beta 4 解决方法中缺少 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，因为 XC12-beta4 没有通过以下方式给我下载/创建选项：

xcrun simctl create <name> <device> <os>

例如

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

Xcode 设备不可用，未找到运行时配置文件

Xcode device Unavailable, runtime profile not found

ios
