Save and cache images in a SwiftUI app | Continued Learning #27

[@tomb.6995]

I have done all 26 parts of SwiftUI Continued Learning and must say it was an excellent structured and high-quality course. everything worked without hiccups technically. Recommend Nick and his teaching style. #27 is a must :) Best one in this course. Thanks :)

Thank you for such great content . Will there be content on algorithms and their comparison depending on randomness ?

Regarding "NS"
"NeXTSTEP was a discontinued object-oriented, multitasking operating system based on the Mach kernel and the UNIX-derived BSD. It was developed by NeXT Computer, founded by Steve Jobs, in the late 1980s and early 1990s and was initially used for its range of proprietary workstation computers such as the NeXTcube."

Great video man! Would love to know that keyboard you're using, satisfying as hell

[@SwiftfulThinking]

This was 2019 MacBook Pro before they changed the keyboard 😰

This modification will delete the cache when you click on the button.
func removeFromCache() {
infoMessage = manager.remove(name: imageName)
cachedImage = nil
}

[@kevincosta2132]

Hello Nick, you said that there are third party libraries that will cache much more efficiently. Which one would you recommend?

[@SwiftfulThinking]

I’m gunna make videos on these soon, but in order:
1. SDWebImageSwiftUI
2. Kingfisher
3. NukeUI

Thank you very much, best content creator like always!@@SwiftfulThinking

Thank you , i implement this idea in my project

[@andresraigoza2082]

Thank you so much Nick. I have a question, is this computed property: "var imageCache: NSCache = { }()" the same as this one:" var imageCache: NSCache { }" ? Or what is the difference?

[@SwiftfulThinking]

We use the () to call the initializer to actually create the object

Great video!

[@ciaociccio5389]

but how can I save images in directory?I mean to show saved images when I re open the app

[@chuljinhwang8386]

Thank you so much, Nick. I have a question. For getFromCache(), due to returnedImage, it does not work properly. When I pressed save, get and remove buttons in order, the image from the cache remains on the screen.

[@dre5671]

Chuljin, this is because of your getFromCache(). When you added the “if let” to safely unwrap the optional, you got rid of the nil.
So, instead of “cacheImage” = nil, it will still = the last image.
If Nick were to try to remove the image from the canvas again at the end of the video, it wouldn’t work for him either.
If you want to have same effect, set cachedImage to nil like so
…} else {
cachedImage = nil
infoMessage = “Not found in cache”
}

[@1slyboy]

Modify the getFromCache else class to set cachedImage back to nil. Then when you get the image again and it is not found, the UI will remove the image from the screen.

thanks again happy to have done all

You are a machine! haha

Thanks Nick

Thanks as always Charlie!

The fact that you kept calling it catch instead of cash is odd hahahaha
