Throw, Try, Try? Try! Catch
Рет қаралды 3,934
4 жыл бұрынMany developers, including myself are confused by the different flavors of the `try` keyword. Swift defines three variations of the `try` keyword.`try`, `try?`, `try!`
You use the try key word when you have a function that throws. What the heck does that mean?
If you are like me, and confused as to what throw means and which flavour of try to use and why, then keep watching this video. Hopefully, I will be able so shed some light.

I followed your 9 part JSON series before coming here to find clarity on everything "throw, do, try, catch" related. I love how you took the time to relate these concepts to your JSON series. You have an extremely thoughtful and Pattern-Recognition-Friendly method of delivering information and interconnecting it to slowly reveal a larger framework. Thank you.

I always wondered why tutorials said try needed to be wrapped in a do catch and this always puzzled me and now I understand the errors are bubbled up to the top. Awesome! thank you very much

omfg this was easily easily the best explanation of this subject. I still don't really understand why a plain "try" is customary at init, but I will check out your decoding series for more info on that.
