Prereqs

Install xcode

Quick Start

  1. yarn rn-gobuild-ios (build the go library)
  2. yarn rn-start ios (start the packager)
  3. open ios/Keybase.xcworkspace (Open workspace (not xcodeproj))
  4. In xcode, select the target Keybase and run.

Building the Go Library

# Build the go keybaselib
yarn rn-gobuild-ios

# if this fails with something like one of these:
#   * xcrun: error: unable to lookup item 'Path' in SDK 'iphoneos'
#   * gomobile: -target=ios requires XCode
# you might have a partial xcode install. try:
xcode-select --switch /Applications/Xcode.app/Contents/Developer

Running on a device

To run on a real phone, first you need to get Nojima or Marco to invite your Apple ID to the Keybase team. Once you accept the invite, you should be able to connect your phone to your computer and get XCode to build onto it.

However, you first have to edit ios/Keybase/AppDelegate.m to use the bundler running on your computer. Look for the comment "Uncomment for prod JS in dev mode" and follow the instructions there.

Alternatively, you could choose "Profile" instead of "Run", which does a prod build and thus doesn't need any bundler changes.

Notifications

They don't work in the simulator at all. If you choose "Run" and build on a phone, they should just work. If you want to do a "Profile" build, look in local-debug.native.js and move config.isDevApplePushToken = true to outside its enclosing if statement.

Troubleshooting

Error watching file for changes:

If you get this error in the React Packager:

React packager ready.

the easiest way to fix it is simply to install watchman:

brew install watchman

clang: error: no such file or directory: ...

If you have Xcode 10 or later and see an error that .../node_modules/react-native/third-party/double-conversion-1.1.6/src/strtod.cc is missing, set Build System to Legacy Build System under file -> Workspace Settings.
