{
 "version": "0.2.0",
 "configurations": [
 {
 "name": "Debug Android",
 "program": "${workspaceRoot}/.vscode/launchReactNative.js",
 "type": "reactnative",
 "request": "launch",
 "platform": "android",
 "sourceMaps": true,
 "outDir": "${workspaceRoot}/.vscode/.react"
 },
 {
 "name": "Debug iOS",
 "program": "${workspaceRoot}/.vscode/launchReactNative.js",
 "type": "reactnative",
 "request": "launch",
 "platform": "ios",
 "target": "iPhone 5s",
 "sourceMaps": true,
 "outDir": "${workspaceRoot}/.vscode/.react"
 },
 {
 "name": "Attach to packager",
 "program": "${workspaceRoot}/.vscode/launchReactNative.js",
 "type": "reactnative",
 "request": "attach",
 "sourceMaps": true,
 "outDir": "${workspaceRoot}/.vscode/.react"

 {
 "name": "Debug in Exponent",

 "program": "${workspaceRoot}/.vscode/launchReactNative.js",
 "type": "reactnative",
 "request": "launch",
 "platform": "ios",
 "sourceMaps": true,
 "target": "iPhone 6s",
 "outDir": "${workspaceRoot}/.vscode/.react"
