Will I get a lot of practice with Error Handling and protocols as I progress in the IOS track?

I understand the concept of protocols and error handling, although, it's still difficult for me to apply these concepts into my own code. Does anyone know if Pasan goes over how to apply these concepts later in the IOS track? Thanks.

Hi Lana,

The best thing I have discovered about Treehouse is that things are introduced at first so you can recognise them. In the future and especially in the Intermediate Swift Track they are all re-introduced and explored even deeper to further your knowledge of how they work.

It helps greatly to cover extra material from the Apple Documentation and YouTube especially to approach concepts if a different way. Further reading on Google and in text books is also a good way to solidify your knowledge.

At an early stage it will always be difficult to apply the code that you learn to your own work because the code that you learn are tools. When an app is actually designed then you can use these tools to match the specification.

Remember that it is a marathon learning Swift or any new language for that matter so it is perfectly fine not to grasp concepts at first and I wouldn't worry.

I wish you all the best,

Mitch
