Swift 4

Whatever you are coding - code clarity is your goal.

To create a .pem file, is quick once you have your .p12 certificate.  I won't go through the process regarding p12 file generation as there are many sites that outline these steps.  If you cannot find a site that outlines this make a comment below and I'll point in the right direction.

Open the terminal and go to the path where you save the apns-cert.p12. where and follow the below command to generate the .PEM file.

I had the issue where I needed to filter an array list by a specific column.  In my instance, the column is language.  To be able to reduce the query to the language column the code required is

levels = selectedCategory?.levels.filter("language = %@", language)

Language can be any string, in this instance for me language is a two alpha character such as 'fr', 'en' or 'de'.

Further to this you can continue to chain this query through including sort as per

iOS localization on the fly

If you have added languages to your app... shortly afterwards you'll be getting yourself knee deep in changing the language on the fly.  Followed by the question – how do you change the language of the app without having to restart the app?  To change the language of the app there are a couple of key steps involved:

A handy resource list of fonts for iOS:

After a short amount searching I came across Kyle Browning Waterwheel Pod.  I flipped down to installation and there it is in three steps.  Super.  But wait.  Step one, CocoaPods.  What are pods?

Easy to follow, in no time cocoapods are added.

Ha you have read it before, one of those throw away lines that is written "just create a cartfile".  So your thinking carthage update, carthage init, create a plain text document, etc... all wrong.  How do you know... when you run carthage update, you receive the following error

Get this error: "No such file in directory"

So how do you "just" create a Cartfile?

After coding for 16 years... I have decided to have a go at building apps in iOS.  Eventually these articles will tell my story as a newbie to app development.

My initial plan is to learn completely differently to how I would normally.  I usually, read a bunch of books about the subject and jump straight in with coding.  This time I will force myself to slow down.  Watch a couple of videos and follow there steps.  Hmm, I will require patience for this!
