It's hardware that makes a machine fast, but it's the software that makes a machine slow. - Craig Bruce
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
whileloops, which you provide with an explicit condition to check. - Although they are similar to
whileloops,repeatloops 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 usebreakfollowed 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!
