Singleton - Good or Bad?

Показать описание

Singleton is one of the most controversial design patterns and in this video, I've tried to analyse if it is actually bad, or some bad practices which makes it look bad. I've discussed the concept, implementation, examples and downsides of Singleton. Also tried to answer the question that if Singleton is so bad, why it has been accepted as a Design Pattern.

Very Very well explained video. I am making an app and at first I too was going to be using it to store variables I needed globally, but turned out what I was looking for was AppStorage. But, now I need to make sure that only one instance of a class is made, and I appreciate that instead of just saying "Singletons are always bad" you explained the reasoning behind it. Thanks a ton!! :)

Hi Pallav, great explanation about singleton. We are still waiting for the 6th video in the series of mastering concurrency.

Hi thanks for the detailed video. i have a query like, if you said manage userdata or coredata functions with singletone then what will be the other approach to manage such kind of usage ? where we need to save or fetch same data multiple times .

Hi, You told about Singleton, But you didn’t explained what should be use instead of Singleton..?

If I am not going to use singleton then what should I use. What patterns similar to Singleton.

"Breaks SOLID"... man i'm sick of solid rules sometimes... we are in 2024 we can skip some of the solid rules... also Apple is using singleton in UserDefaults. Everyone uses userdefaults so this mean we break the solid shitprinciples?
