Swift is designed in a manner that allows the development platform to automatically eliminate entire lines of unsafe code. The development platform relies upon an array of in-built functionalities that allow developers to create almost deployable apps.

What are those functionalities?

Well, some of the most revered functionalities of the Swift development platform are mentioned in the sections below.

  • Variables will be initialized before they are used
  • Both integers and arrays will be checked to keep overflows at bay.
  • Memory management is carried out automatically.
  • Exclusive access to memory guards is enforced in a bid to keep programming mistakes at bay.
  • Swift-based apps are highly scalable and performance-oriented

Swift, as a development platform, adds an impressive scalability factor to apps. Swift is used to developing high-performance apps that entail complex architectures and the project entails high standards. To put things into perspective, here is a short list of apps that are developed using Swift:

  • Facebook
  • Slack
  • LinkedIn
  • Lyft
  • Uber
  • WhatsApp.

Conclusion Both development frameworks entail certain Unique Selling Points. To choose the best development platform, feel free to consult with our iOS app development experts by calling +91 9910409680 or by sending an email to ankur@wearetechtonic.com
