How to symbolicate iOS crash logs in Mac?
(Provided you have the crash log, the iOS build in which the crash occured and the .dSYM file)

1. Copy the .crash file and .dSYM file into a folder and navigate to the folder in terminal
2. Run the following command to make sure the correct XCode developer tools is selected, in case you have multiple XCode versions.
     `sudo xcode-select --switch /Applications/Xcode\ 6.3.app/Contents/Developer`
3. Finally run the following command to get the symbolicated crash log in the same folder.
    DEVELOPER_DIR=`xcode-select -print-path` /Applications/Xcode\ 6.3.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash  -o ./MyApp.crash ./MyApp.crash ./MyApp.app.dSYM

- Connect the device via USB and make sure debugging is working
- Run `adb tcpip 5555` in the terminal. This makes the device to start listening for connections on port 5555
- Look up the device IP address with `adb shell netcfg` or `adb shell ifconfig` with 6.0 and higher
- You can disconnect the USB now
- Type `adb connect <DEVICE_IP_ADDRESS>:5555` in the terminal. This connects to the server we set up on the device on step 2
- Now you have a device over the network with which you can debug as usual.
