Ios Development Questions
In iOS development, a filter is a component that processes data or modifies its behavior in some way. It takes an input and produces an output based on a specific set of rules or criteria. Filters can be used to perform tasks such as data validation, data transformation, or data manipulation.
On the other hand, a filter chain is a sequence or collection of multiple filters that are applied in a specific order. Each filter in the chain takes the output of the previous filter as its input and produces a new output. The purpose of a filter chain is to apply a series of transformations or operations on the data in a systematic manner.
In summary, the main difference between a filter and a filter chain is that a filter is an individual component that processes data, while a filter chain is a collection of filters that are applied sequentially to achieve a desired outcome.
