how to set up iOS code signing with a personal free provisioning team with xcodegen

set-up-xcodegen-signing-personal-team.md

I recently wrestled with the clusterfuck that is iOS code signing, so here's my setup to set up a swift xcodegen project signed with a personal (free) provisioning team. this doesn't require an apple developer account, just a regular apple id.

you'll be able to build whole thing from the command line without ever have to touch xcode ever again.

this was tested with xcode 10.0 (10A255) on High Sierra

• open xcode
• file -> preferences
• accounts
• log into your apple id
• create a personal team
• click manage certificates
• click the '+' and select "iOS Development"

save this script as xcodeteam.sh

#!/bin/sh

# pick a code signing identity and get the associated xcode team id
# requires percol (pip install percol)

cert="$( \
  security find-identity -p codesigning -v \
  | awk '{$1=$2=""; print $0}' \
  | sed '$d' \
  | sed 's/  //g' \
  | sed 's/"//g' \
  | percol \
)"

if [ -z "$cert" ]; then
  echo "canceled"
  exit 0
fi

security find-certificate -c "$cert" -p | openssl x509 -text \
| grep -o OU=[^,]* \
| grep -v Apple \
| sed s/OU=//g

install dependencies and run it

brew install python
pip3 install --user percol
export PATH="~/Library/Python/3.7/bin:$PATH"
chmod +x ./xcodeteam.sh
./xcodeteam.sh

the script will prompt you to pick one of your identities, you should pick one of the "iPhone Developer" ones that matches your apple id.

press enter to confirm and it will print out your team id. copy this, we'll need it in a moment

here's an example project that uses SnapKit

project.yml

name: example
options:
  bundleIdPrefix: $(OSX_NAMESPACE).example
settings:
  DEVELOPMENT_TEAM: $(OSX_DEVELOPMENT_TEAM)
targets:
  Example:
    type: application
    platform: iOS
    deploymentTarget: "8.0"
    sources:
    - AppDelegate.swift
    - ExampleViewController.swift
    - Info.plist

build.sh

#!/bin/sh

workdir="$(dirname $(realpath "$0"))"

rm -rf "$workdir/build" || exit $?
xcodegen && pod install || exit $?
xcodebuild \
  -scheme Example \
  -workspace example.xcworkspace \
  -configuration Debug \
  -allowProvisioningUpdates \
  BUILD_DIR="$workdir/build" \
  || exit $?

ios-deploy --noninteractive --debug --bundle \
  "$workdir"/build/Debug-iphoneos/*.app

Podfile

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target 'Example' do
  pod 'SnapKit', '~> 4.0.0'
end

AppDelegate.swift

import UIKit

@UIApplicationMain
class AppDelegate : UIResponder, UIApplicationDelegate {
  var window : UIWindow?

  func application(_ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions:
      [UIApplicationLaunchOptionsKey: Any]?) -> Bool
  {
    window = UIWindow(frame : UIScreen.main.bounds)
    window!.rootViewController = ExampleViewController()
    window!.makeKeyAndVisible()
    return true
  }
}

ExampleViewController.swift

import SnapKit

class ExampleViewController : UITableViewController {
  override func viewDidLoad() {
    super.viewDidLoad()
    view.backgroundColor = .red
  }
}

just put everything in one folder

install any dependency you might not have:

gem install --user cocoapods
export PATH="~/.gem/ruby/2.3.0/bin:$PATH"
brew install xcodegen ios-deploy

now you can build like so

export OSX_NAMESPACE=com.something
export OSX_DEVELOPMENT_TEAM=yourdevteam
chmod +x ./build.sh
./build.sh

yourdevteam is the team id you obtained earlier

you most likely want to export those environment variables in your ~/.bash_profile so they persist.

if your ipad or iphone is connected to your mac, the application should pop right up and display a red screen

have fun!
