| Say you have a list of a random hashable type (the same type throughout), in an arbitrary order. | |
| How do you find the most common item in the list (along with its count) after the first instance of a given item? | |
| Examples: | |
| [1, 1, 1, 2, 3, 4, 4, 1], 2 -> (4, 2) | |
| [1, 1, 1, 2, 3, 4, 4, 1], 1 -> (1, 3) | |
| ["red", "green", "blue", "green", "blue"], "green" -> ("blue", 2) | |
| What we're really looking for here is not just a working solution, but well-crafted, idiomatic Swift. | |
| We want to see an API that fits with Swift APIs, with clear separation of concerns and well-named functions and variables. |
Sublime Text includes a command line tool, subl, to work with files on the command line. This can be used to open files and projects in Sublime Text, as well working as an EDITOR for unix tools, such as git and subversion.

| // Swift's untyped errors are a goddam PiTA. Here's the pattern I use to try to work around this. | |
| // The goal is basically to try to guarantee that every throwing function in the app throws an | |
| // ApplicationError instead of some unknown error type. We can't actually enforce this statically | |
| // But by following this convention we can simplify error handling | |
| enum ApplicationError: Error, CustomStringConvertible { | |
| // These are application-specific errors that may need special treatment | |
| case specificError1 | |
| case specificError2(SomeType) |

It is important to enable Bitcode in all libraries if the app is going to enable Bitcode. These scripts check each static library for Bitcode and echo a string which shows up as a warning in the build log. It is an easy way to always check that the dependencies have what is needed.
Place check_bitcode.sh in your project directory. Then add a Run Script in Build Phasese with the script named RunScript.sh. Name that new section as Check Bitcode and run the build. It may be necessary to make the shell script executble using chmod u+x check_bitcode.sh on the command-line.
At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.
git commit --amendThis will open your $EDITOR and let you change the message. Continue with your usual git push origin master.

This is a well known issue, and it has a solution that is confirmed to work for the Mac side.
sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid
After you run this script, the issue will go away and BT connections will remain stable.
| 1. Open Terminal | |
| 2. cd to your Xcode project | |
| 3. Execute the following when inside your target project: | |
| find . -name "*.[hm]" -print0 | xargs -0 wc -l |
