Answer 1

• Connect the iPad or iPhone to the Mac and sync it as usual
• Hit Command+Shift+G and navigate to ~/Library/Logs/CrashReporter/MobileDevice/
• For those with multiple iOS devices, select the proper device that you want to retrieve the crash log from
• Look for files with the app name you want the crash reports from, copy that out of the folder, or copy multiple logs and zip them up

Answer 2

You can collect an Xcode sysdiagnose log using the following command in the terminal:

sudo sysdiagnose Xcode

This presents the following information:

This tool generates files that allow Apple to investigate issues with your computer and help improve Apple products. The files might contain personal information found on your device or associated with your iCloud accounts, including but not limited to your name, serial numbers of your device, your device name, your attached peripheral devices, your user name, your email address and email settings, file paths, file names, Siri suggestions, your computer's IP addresses, and network connection information.

This information is used by Apple in accordance with its privacy policy (www.apple.com/privacy) and is not shared with any other company. By using this tool and sending the results to Apple, you consent to Apple using the contents of these files to improve Apple products.

The process can take up to 10 minutes to complete.

The resulting tar.gz file will be found in /private/var/tmp when completed and can be 100's of Mbs in size.

Answer 3

I do not believe Xcode writes a dedicated log file. However, the Console app should have everything you need (you'd need to filter by PROCESS|Xcode to see only Xcode entries).

Alternatively, starting Xcode from the terminal window (via /Applications/Xcode-beta.app/Contents/MacOS/Xcode) should produce only Xcode logs.
