Xcode 11でReact Nativeアプリが起動しなくなった場合の対処法

Last updated at Posted at 2019-09-30

Xcode 11に更新後、既存のReact Nativeアプリが実行時エラーで起動しなくなりましたが、以下の方法で対処して起動できました。

Xcodeから実行して、実行時エラーが出た場合 (1)

以下の実行時エラーが出た場合の対応を記します。

Synchronous remote object proxy returned error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service on pid 0 named com.apple.commcenter.coretelephony.xpc was invalidated."

以下のコマンドで、シミュレータの設定をしてください。

xcrun simctl spawn booted log config --mode "level:off"  --subsystem com.apple.CoreTelephony

情報源はこちら。

Xcodeから実行して、実行時エラーが出た場合 (2)

以下の実行時エラーが出た場合の対応を記します。

[error][tid:main][RCTModuleMethod.mm:375] Unknown argument type '__attribute__' in method -[RCTAppState getCurrentAppState:error:]. Extend RCTConvert to support this type.

react-nativeを0.59.9以上に更新してください。

react-nativeを更新したくない場合は、node_modules/react-native/React/Base/RCTModuleMethod.mmを直接書き換えてください。(公式リポジトリでの修正はこちら

static BOOL RCTParseUnused(const char **input)
{
  return RCTReadString(input, "__attribute__((unused))") ||
         RCTReadString(input, "__attribute__((__unused__))") || // この行を追加
         RCTReadString(input, "__unused");
}

react-native コマンドからシミュレータを起動できない場合

例えば以下のように、シミュレータを起動できなかった場合の対応を記します。

$ react-native run-ios --simulator "iPad (5th generation)"
Found Xcode project YourProject.xcodeproj
CoreData: annotation:  Failed to load optimized model at path '/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Frameworks/InstrumentsPackaging.framework/Versions/A/Resources/XRPackageModel.momd/XRPackageModel 9.0.omo'

Could not find iPad (5th generation) simulator

Error: Could not find iPad (5th generation) simulator
    at resolve (/Users/YourName/Documents/YourProject/node_modules/react-native/local-cli/runIOS/runIOS.js:149:13)
    at new Promise (<anonymous>)

    at Promise.resolve.then (/Users/YourName/Documents/YourProject/node_modules/react-native/local-cli/cliEntry.js:117:22)

node_modules/react-native/local-cli/runIOS/findMatchingSimulator.jsfunction findMatchingSimulator(simulators, simulatorString)内を、以下のように修正してください。

    if (!version.startsWith('com.apple.CoreSimulator.SimRuntime.iOS') && !version.startsWith('com.apple.CoreSimulator.SimRuntime.tvOS')) {
//  if (!version.startsWith('iOS') && !version.startsWith('tvOS')) { この行を修正

情報源はこちら

        simulator.isAvailable !== true
//      simulator.isAvailable !== 'YES' この行を修正
