Swift Vs Objective-C the ultimate answer

Since 2014 Swift programming language has gotten the fascination of developers and strangers, but what about the old and reliable Objective-C, that for years has been the default language in iOS and OSX applications. Is Objective-C dead? Do the new generations should only know Swift? Is Swift the tool for everything? In this article, I will try to answer those questions, by comparing them in different categories. > In this article I am not considering backend development with Swift

What and where precision matters

It is well known in all programming languages the floating point math loses some accuracy. Therefore we have something like the following statement 0.1 + 0.2 != 0.3 This is explained in detail in here, but basically, is because some fractional numbers aren’t well represented on binary, and the carryover loses accuracy, but it keeps precise. There are several ways to mitigate this effect, the most known use double numbers or big decimal representations, the problem with those is the operations tend to use more computing resources, especially with BigNumbers, that usually are objects with large strings and complicated math behind.
