+## Day 4 - HackingWithSwift - 100DaysOfSwiftUI Challenge
+
+> It's hardware that makes a machine fast, but it's the software that makes a machine slow. - Craig Bruce
+
+### Loops
+
+Today I learnt about:
+
+- For loops
+- While loops
+- Repeat loops
+- Exiting loops (ie: ```break```)
+- Exiting multiple loops 
+- Skipping items (ie: ```continue```)
+- Infinite loops
+
+The summary of the entire day was:
+
+- Loops let us repeat code until a condition is false.
+- The most common loop is ```for```, which assigns each item inside the loop to a temporary constant.
+- If you don’t need the temporary constant that ```for loops give you, use an underscore instead so Swift can skip that work.
+- There are ```while``` loops, which you provide with an explicit condition to check.
+- Although they are similar to ```while``` loops, ```repeat``` loops always run the body of their loop at least once.
+- You can exit a single loop using ```break```, but if you have nested loops you need to use ```break``` followed by whatever label you placed before your outer loop.
+- You can skip items in a loop using ```continue```.
+- Infinite loops don’t end until you ask them to, and are made using ```while true```. Make sure you have a condition somewhere to end your infinite loops!
+
+**That's all for the Day 4 of 100DaysOfSwiftUI!**
