Nick Walter Swift 5 Course - Part 6 (lectures 35 to 37)

So here we go! The last part of Nick's course. It's been a really useful 'refresher'. Having missed a month's worth of coding, and to be honest before that, I hadn't really touched on those concepts of late, it was much needed! I think it's healthy to go over the core concepts, especially when there have been updates to Swifts. I always glean useful things or had forgotten certain elements. The coding challenge at the end of the Intermediate Swift Chapter was soooo hard but I learned from it. Last part - Xcode app. Only several lessons ago so will probably be pretty basic. Still worth doing!

Start Time - 18:33

Labels

Just a walkthrough of the main view screen etc. Reminders of the device type affects screen size. Matching up the screen on Xcode to what you will view on for sanity's sake!

Outlets

Under Super.ViewDidLoad - this is separate to the main code on the view controller.

view.backgroundColor = .red

OK, maybe it's a Swift 5 thing but I used .red instead of UIRed. 

Paused at 18:48 (15 minutes so far)

Continued at 20:23

So I noticed this - 

Hi Nick!

 When changing the background colour to red, I found that you can do the following -

 view.backgroundColor = .red

 Same
So the UIColor keyword is not needed. Is this a feature of Swift 5? Or is it the case for accessing properties for views etc. in general?

 Thanks,

That's my message to put on the course Q&A!

Other key things with labels - checking the outlet, renaming etc. Things like that. I'm fine with connecting these.

Buttons

Again, all of this is easy.

@IBOutlet weak var textLabel: UILabel!
    
    @IBAction func changeText(_ sender: Any) {
        textLabel.text = "The text has now changed!"

    }



Finish Time - 20:42 (TOTAL TIME - 34 minutes)

I've ran out of time for today - just a short session with the interruptions! So will finish off tomorrow instead....or the next day! Either way, I feel good to be back in the coding zone. Next time it will be if statements and counting - all easy enough.

*Xcode Project Entry 2* F1 Quiz - part 1

Image
It's Christmas Eve and time to code! To think, a year ago, I was plodding along with some eBook, blindly convincing myself that I was on a steady road to coding greatness. Really, it was from June where I made the decision to start again, humbling as that may seem. It would have been comforting to have completed endless 'beginner' courses but branching out and applying the theory is the key thing, which brings us to this entry. Yes, my second Xcode OWN project! I thought about doing an educational one, as there is certainly a lot of scope and relevance for that, being a teacher and all. However, making a quiz makes sense, for various reasons.  First off, I have made this before through Angela's excellent tutorial. No offence to Sandra, but hers is not even close to the elegance and effectiveness of Angela's project. The one thing to take from Sandra is the stack views. Definitely something I will use from now on. This is one of the great things about learning from...

Angela Yu Course Part 10 (up to lesson 112)

It's unlikely that I'll be able to do any Swift tomorrow as I'm going to Eastbourne today, for the weekend. So I can give half an hour now, maximum! Coding Challenge - Destini App! Choose your own adventure books! I used to ADORE these. Angela explains that these have had some sort of revival through the Lifeline games. It's very binary - yes/no mostly. I have my own experience of this based on WDC... Now the challenge is to complete the game! Having followed the first few instructions, which I found a bit confusing it must be said, I was about to surrender and see the answer. Then I managed to stop myself - I CAN do this, or at least have a good go! Even if I don't get the correct answer, it will be good practice to put what I know into practice. This is my weakness, which I keep coming back to - that when some problem solving is required, I fold far too quickly. So here is what I need to do: Let's break this down... I need to use the...

Angela Yu Xcode 12 Course - Part 7 (lectures 74 to 79)

No time to waste! Only got a short amount of time now so going to get a few minutes or so in! Start Time - 20:14 Conditionals If statement for 'love calculator' example. So a simple example for this. The idea will be that conditionals are used to show that the print statement will do it differently for whatever the number is. With updated Swift, I would use the Int.random(0...100). Easy fix that would be. Also no UIInt32 needed but just an Int. So with the if statements, it would be a STRING being returned.   Linked to the whole choose your own adventure - if/else for each choice. BMI Challenge No need to do this - easy enough to be honest. Just skimming through. BODMAS principles... So something I picked up on before is not needing the greater than AND less than value for the middle line (for the else if bmi > 18.5) A better solution, which Angela is already explaining before I could say it is returning a string instead of a Double. So the...
