How to use Charles Proxy on the Xcode 6 (iOS 8) Si

Question

It seems that the directory for the iOS Simulator has changed. It used to be in ~/Library/Application\ Support/iPhone\ Simulator/ and now it's in ~/Library/Developer/CoreSimulator/Devices/.

Answer 1

I didnt see the configuration shell script on that page. I did the following and it worked for me:

Answer 2

Another way to do it is to browse to the certificate http://charlesproxy.com/charles.crt on the device

which will present you with the screen:

Answer 3

For those who struggling with untrusted connections on Xcode 9 beta's simulators:

I don't know if install script works or not but you are able to install charles' cert in same way as on physical device - through Safari.

Last step that is needed (of course after installing certificate either through script or via Safari): Go to Simluator's settings -> general -> about -> Certificate trust settings -> Charles Proxy Custom Root... -> enable

Update: Charles 3.9.3+ has a built-in function to configure your iOS Simulators (i.e. installing the Charles SSL Certificate). This can be found in the Help menu within the Charles application. (Help > SSL Proxying > Install Charles Root Certificate in iOS Simulators)

The following applies to Charles 3.9.2:

Download the configuration shell script from the Charles Proxy website. Then, replace the script with the following, and run it on your Mac:

#/bin/bash
install() {
if [ -f "$SQLITEDBPATH" ]; then
cp -n "$SQLITEDBPATH" "$SQLITEDBPATH.charlesbackup"
sqlite3 "$SQLITEDBPATH" <<EOF

Some things to note:

• you must open Charles before launching the simulator. If you close Charles, network requests will fail until you restart the simulator
• you will need to do this every time you "Reset Content and Settings..." on the simulator
• For Xcode 5: if you're looking to setup Charles Proxy on Xcode 5 and earlier, you don't need to modify the original script. Just download it from the Charles website and run it as-is

Answer 5

Check this out:

As of Charles v3.9.3 there is an item in the Help menu, "Install Charles CA SSL Certificate in iOS Simulators", which will automatically install Charles's SSL CA certificate in your iOS Simulators.

Alternatively, you can change your code so that NSURLConnection accepts any SSL certificate. Please see the question and answer on Stack Overflow: How to use NSURLConnection to connect with SSL for an untrusted cert?

You can check it on this link: http://www.charlesproxy.com/documentation/faqs/ssl-connections-from-within-iphone-applications/

Answer 6

I just tested Charles over Xcode 7 / iOS9 simulator. Just a few pointers I want to add if you're having trouble:

• Make sure "Enable Mac OS proxy" and "Use HTTP Proxy" are checked under Charles' Proxy | Proxy Settings; and optionally check "Enable Mac OS X proxy at startup" if you don't want to do this step every time you start Charles.
• If your Automatic Proxy Configuration (and/or Auto Proxy Discovery) is set in your System Preferences | Network, you need to uncheck it lest Charles' Web Proxy (HTTP) and Secure Web Proxy (HTTPS) will not take effect.
• If your company requires proxy server independent of Charles, you need to manually replicate the settings inside Charles lest they are overridden by Charles and you won't be able to access the internet. Make note of the proxy URL and port numbers before starting Charles. Transcribe these Web Proxy and Secure Web Proxy settings under Charles' Proxy | External Proxy Settings.
• "Enable SSL Proxying" and add your endpoint on the list, via Charles' Proxy | SSL Proxying Settings.
• "Install Charles Root Certificate in iOS Simulator" via Charles' Help | SSL Proxying menu.
• And yeah, make sure Charles is setup and started first before you start the simulator.
• Finally for now, disable ATS during development until we hear more from Apple.
