},
{
"name": "Debug iOS",
"program": "${workspaceRoot}/.vscode/launchReactNative.js",
"type": "reactnative",
"request": "launch",
"platform": "ios",
"target": "iPhone 5s",
"sourceMaps": true,
"outDir": "${workspaceRoot}/.vscode/.react"
},
{

"type": "reactnative",
"request": "attach",
"sourceMaps": true,
