Why is Objective C dead?
According to the February 2020 update: Objective-C lost another seven positions in the TIOBE index this month and is on the cusp of slipping out of the top 20. This decline lasted much longer than expected. In 2014, Apple announced the new programming language, Swift, as the successor to Objective-C.
Why is Objective C better than Swift?
Swift is faster than Objective-C, as it removed the limitations of the C language and enhanced it by using advanced software development technologies that were unavailable when C was developed. Speed depends on a programmer’s level and capabilities, as a slow app can also be written in Swift.
Is Flutter better than swift?
As a native technology, Swift should be more stable and reliable on iOS than Flutter. However, that’s only the case if you find and hire a top-notch Swift developer who can get the most out of Apple’s solutions.
